#51 Exploring the digital revolution paradox from a UN perspective with Paz Pena and Pablo José Gamez Cersosimo

It’s a 252 pages report with the foreword of António Guterres, the Secretary-General of the United Nations, talking about digitalization and sustainability. And, for once, it’s not another report from the UN stating “let’s digitize everything to boost sustainability”. Quite the contrary as it states a “unequal ecological exchange between developed and developing countries regarding digitization”. To discuss this “scientific report based on an ethical approach” as he described it, we welcome one of its contributors, Pablo José Gamez Cersosimo, based in the Netherlands. Another contributor, Paz Pena Ochoa, based in Chile, joined us to share her unique perspective on Latin America. Together they shared great insights about:    🗺️ Colonialism and Digitalization   🪨 Geopolitical Importance of Critical Minerals   💧 Water Footprint of Digitalization   ⚒️ Water Usage and Mining in Chile   🔎 The Digital Divide: A Growing Gap   🇺🇳 The Role of the UN in Digital Sustainability   And much more!❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode, twice a month, on Tuesday!📧 Once a month, you get carefully curated news on digital sustainability packed with exclusive Green IO contents, subscribe to the Green IO newsletter here.  📣 The CFP for the 2025 Green IO Conferences is now live.

It is the water that makes virtuality possible. That digital light is as blue as the fresh water that make it possible.Gaël Duez (00:19)Hello everyone, welcome to Green.io. I'm Gaël Duez and in this podcast we empower responsible technologists to build a greener digital world, one byte at a time. Twice a month, our guests from across the globe share insights, tools and alternative approaches enabling people within the tech sector and beyond to boost digital sustainability. This episode is the first of 2025. And being released on January 30th, I can still wish you a happy new year, full of positive impacts. I hope you will find many occasions in 2025 for using technology responsibly, in order to maintain our world livable and our societies just inclusive and at peace. Full disclosure, I am sorry if I couldn't release this first episode of the year sooner, but January was a bit rough both on professional and personal level. Fortunately, everything is getting back on track, including your bi-monthly podcast. And something that is still on track is accessibility and transparent information remaining in the DNA of Green.io, so all the references mentioned in this episode as well as the full transcript are in the show notes. You can find these notes on your favorite podcast platform and of course on our website, greenio.tech.Gaël Duez (01:53)it's a 252 pages report with the foreword of Antonio Guterres, the secretary general of the United Nations, talking about digitalization and sustainability. And for once, it's not another report from the UN stating, let's digitize everything to boost sustainability. Quite the contrary, the report highlights the growing environmental impact of the digital economy and underscores the urgent need for environmentally sustainable and inclusive digitalization strategies. Quite a change. To discuss their insights and their implications, I am delighted to have with me two of its contributors. Pablo Jose Gámez-Certrozimo, based in the Netherlands, and Paz Pena Ochoa based in Chile. So yes, another 3 time zones Paz has dedicated more than 15 years to studying the intersection between technologies, social justice and gender. She has spent the last 5 years researching the socio-environmental impacts of digital technologies in Latin America, creating in 2021 the Latin American Institute of Terraforming. And in 2023, she published a summary of that research in the book Technologies for a Burning Planet, which is in Spanish, but I won't try to say it in Spanish, but you will have the link as usual in the show notes. And by the way, this book also made a great contribution to the branch magazine of Climate Action Tech. Pablo is an external researcher for the United Nations Conference on Trade and Development, UNCTAD, as well as a coach and a scientific journalist. His research includes the publication of Depreda... I shouldn't say it in Spanish as well, but I'm going to try. His research includes the publication of Depredadores Digitales 2021, which is a global investigation that sheds light on the complex digital carbon water and waste footprints of digitalizations.Welcome Paz, welcome Pablo. It's great to have you on the show today.Pablo Gámez Cersosimo (04:15)Thank you for having us in your program.Paz Peña (04:18)Yeah, thank you very much for having us.Gaël Duez (04:20)My pleasure, both of you.So Paz, is it the first UN-backed report ever to address the environmental impact of digitalization?Paz Peña (04:30)Yes, it is.Gaël Duez (04:32)So that's a kind of a game changer, isn't it?Paz Peña (04:34)Yes, I will say absolutely. As you said before, is a report that I will say one of the first reports by the UN saying that digitalization is not all good. Even more saying that the social environmental impacts of digitization are huge, but not only huge, are differential depending on where you are in the world.And this is very important because what it's saying is that the social environmental impacts of digitization, which are growing through the time, is being paid by the poorest of the world. The developing countries, the poorest countries. And again, the benefits of digitization.are being enjoyed almost only for the developed world, which brings us a very classical and difficult concept, which is the colonial relationships that are again being deployed in digitization, which is something really difficult to address in the UN, but it's so necessary in these times where sustainable or sustainability is being discussed as a justice issue. And that actually brings us to discuss how digitization can be a justice issue in terms of sustainability.Gaël Duez (06:09)And just to understand like the concept of colonialism or neo colonialism was brought to light in the UN report or is it more like an underlying evolution in the state of mind of UN representatives starting to incorporate this concept also in a main report as this one?Paz Peña (06:30)Yeah, they will not name colonialism as it is. I don't know, Pablo, if you saw that concept as it is, because it's a very political, difficult concept for a UN fora, However, yeah, exactly. However you can see powerful concepts as, you know, unjusties, you know, different effects between the world, etc. You can see actually what they are saying is about colonialism, but of course they are not named as it is, because probably it's a very difficult concept to address in the UN.Pablo Gámez Cersosimo (07:01)It is in between lines, I will say it. And to add what Paz already said, this report is the result of a process of a critical thinking process that took almost 18 months from 2023 to 2024. And it is also the result of the work of several scientific researchers from all over the world that were here for the first time, let's call it the first time at Geneva, to address the externalities regarding the digital ecosystem we are dealing with and not only that, that we are seeing intensifying in a way that we have never seen before. This is really important to address and this is the timely that explains the importance of this critical report. It is a scientific report based on an ethical approach.If you go deeply in this report, it says developing countries are suffering disproportionately from digitalization's negative environmental externalities of effects, as well as missing out on economic development opportunities to digital divides.It used the term unequal ecological exchange between developed and developing countries regarding digitalization. And this is also an complementary part of what Bas already said and your question. It is in between colonialism or neocolonialism.Gaël Duez (09:20)just before we deep dive into the importance of this report and maybe what's in this report, two short questions. The first one you mentioned that it was a scientific work. Was it mostly based on primary data or is it more an aggregation of other scientific studies that were used to build the end results?Pablo Gámez Cersosimo (09:44)It took and it used several primary and secondary resources. it is the most comprehensive integral report until now. It looks back from 1996 from the first ever report on digital sustainability until now. It addressed the problematic behind the methodologies that every single report used to say this and to say that. And there is no continuity at all because there is no universal understanding of methodology on how to deal with what we call the digital ecosystem. What is the digital ecosystem? That's your e-bike right now is part of the digital ecosystem or your Tesla car because they are already computers. They are already intelligent. They are already smart. We use also the primary data United Nations has with several agencies all around the world. And what you read, And this is really important to say also is a really comprehensive report. It is right in a common language that you and me can understand.Gaël Duez (11:22)So if I understand both of you right and if you indulge me to sum up a bit what you've said, this is the first of its kind tackling this issue. It has a broad ambition of tackling quite difficult topics, even if some of them are not named, but at least they are addressed.And it's also one of the most comprehensive based on several studies, quite a lot of researchers being involved. So I think it's a fair statement to say that pretty much everyone working in the digital economy should have a look at it. Am I right?Pablo Gámez Cersosimo (12:04)it is for everyone, for you and me, for the common ones, for all the ones involved in a digital transformation society. It is not only for politicians, it's not only for ICT. No, it is for the common people, for you and me.Gaël Duez (12:27)So I think we've teased enough about this report. Maybe Paz, if you allow me to ask you these questions. On the impact side, and we will talk a bit later on this very important social justice concept that you've raised, but on the impact size, what are the main findings? Maybe what are the one or two numbers that you believe everyone should be aware when it comes to the environmental impact of digitalization?Paz Peña (12:56)Sure, so first I will say that one of the greatest thing about this report is that Big Tech is not present there in terms of giving their reports as evidence. It's a very independent report, which is not so common even in the UN. I will say ANTAT is one of the few UN agencies that is still very independent in terms of funding, et cetera. And you can find here that this is a proof that big tech, these big companies are not present there. Actually, we were with Pablo doing the peer review in a couple of meetings with people of, UNCTAD's people, they were all independent researchers, which was very, very rich because the discussion was very, very honest. That is the first thing that is important to say because what you're gonna see in this report, it's scientific evidence, it's not big tech evidence, And the second thing that is really interesting is when you see actually the evidence of environmental impacts of sustainability is not a conversation only focused on CO2 emissions, which is a very important thing because of the use of energy and increase of the use of energy of digitization, but it's very...focus on the necessities of the global north, which is of course very important because the global north doesn't have energy matrix that is clean yet. But that is not actually a very big issue for the global south. For example, Latin America is the continent that has today the most clean energy matrix in the world.So the use of energy of digitization, it's important, of course, but it's not really the main issue here in the global south in terms of the environmental effects of digitization. So one of the things that for me, it's more interesting about the report is that actually has complete evidence there about carbon and digital technologies largely compete for the same critical minerals, especially in the global South. So...Minerals are a geopolitical factor that is actually activating policies around the global south from the global north to actually have access to these minerals. And then here you can actually start the discussion about how these geopolitical necessity of the global north of accessing to these critical minerals is actually affecting developing countries in terms of how this is feeding illegal mining for example or unsustainable practices in mining because that is where the money is today.Gaël Duez (16:07)I'd like to ask you one last question to get things a bit more concrete here, because you mentioned several times how the report is important, but most of the listeners, will not have read the report. So let me ask you this question to give you the opportunity to provide a bit of numbers or facts that are mind blowing enough for people to remember and to understand what you are highlighting. So, Paz, you've mentioned that actually digitalizations and the transition towards low carbon economy, they tend to compete for the same resources, especially minerals.Pablo Gámez Cersosimo (16:54)By 2050, we will need more than 150 billion tons of minerals annually. And that will include 50 new lithium mines, 60 new nickel mines, and the production of rare earth metals must be increased at last 12 folds. If you look...into e-waste this year or just published a couple of days ago by 2022 the world generated 62 billion kilograms of e-waste.It is extremely important to say the complexity we are dealing with when we try to define once again what is a digital device, what is a digital infrastructure, and what is not. Because if you look once again the example of an e-bike or a Tesla car.then we have to consider them as part of this digital ecosystem, but at the same time as part of the transitional electrification that we are dealing with. The way IoT devices are being created is a moving target that makes really difficult the definition right now of what is a digital device, what is not a digital device. But the main point here is how transitional minerals, that's the word we use in the report to refer to critical minerals, how the amounts of transitional minerals we are going to need. We are talking about open-bit mining. We are talking about the renaissance of the mining industry. We are talking about that we are completely dependent on all elements of the periodic and to obtain them you are not going to find them in Europe. You have to go to Global South to get them.Gaël Duez (19:19)And my question, Pablo, regarding this is really, what is the share of digital? mean, if I understand you right, what you're saying is pretty much everything is digital now. Am I right?Pablo Gámez Cersosimo (19:29)electrify and digital. We are living an electrification era and at the same time we are dealing with an internet intelligent era that is taking for its own almost everything, almost every device we use daily.Gaël Duez (19:52)Because in the research field, there are several, I would say, debates still going on on how you define what is the ICT sector and what is not the ICT sector. And what is the share of greenhouse gases emitted by the ICT sector? And usually it's believed between 2 and 4%, depending on the studies, et cetera, et cetera. And your point is...It's slightly irrelevant because the digital economy is fueling the entire economy I mean, you follow Malmöder, for instance, he has a very strong stance on what should be in the digital economy or counted as ICT and what should not like the TV debate, et cetera, et cetera. Your point isAnd that's maybe the point in this report as well. That doesn't really matter that strongly to draw a very clear boundary because electrification is everywhere, digitalization is everywhere, and that fueled the trend in this massive increase in mineral resources that you've just described a bit earlier. Am I correct to rephrase you that way?Pablo Gámez Cersosimo (21:06)you are completely correct.Gaël Duez (21:08)Okay, thanks. I got it.Pablo, you were mentioning having a holistic view on everything and I guess both of you, you stressed quite a lot the abiotic resources, mostly metals and minerals. But there are also other impacts that are touched upon in this report.We cannot list all of them, but can I briefly ask you to share maybe one or two figures or one or two facts that you believe are also very important when it comes to environmental impacts? And as far as I know, Pablo, you're quite keen on studying the water usage of the digital sector. Maybe you've got some things to tell us about.Pablo Gámez Cersosimo (21:55)Sure. we can understand this better if we say that the more virtual we become, the more fresh and potable water we need for that. And that means that our digital world is literally liquids. We surf the internet, navigating and diving into its waters. And I want to be here clear enough, Kyle. It is the water that makes virtuality possible. That digital light is as blue as the fresh water that make it possible.Now I'm talking here about data center industry. Here I'm talking now about the semiconductor industry. I'm talking here about the open pit mining industry.I'm talking here about the production of our gadgets,Gaël Duez (23:04)I there are quite a lot of examples about this, maybe Paz being based in Chile. I think this is one of the countries where the tension between the mining industries and the population regarding water usage has been one of the fiercest. So do you want to comment on what Pablo just said?Paz Peña (23:26)Yes, absolutely. in all Latin America, one of the biggest climate effects today is drought. And you can see that in different states. But in the case of Chile, Chile is suffering a historical drought for over 30 years where water is scarce, even for human consumption. And you can see that many of the territorial fights for different communities is actually the access of fresh water. And this is something that is present in mining activities, but also which are related to the digitization, for example, in terms of the lithium mining in the north of Chile, which is one of the biggest worldwide resources of lithium to digitization and green energies. And the fight there from indigenous communities is actually how this mining is affecting the access of fresh water for indigenous community there, which is basicallyhaving a very concrete impact in terms of the environment. Natural, different animals, for example, are being displaced from that place because of this scarcity of water. But also these indigenous communities are being displaced of their territories because of this, which is again something that we must discuss as a society why indigenous communities that haven't actually contributed to the ecological crisis and climate crisis that we are facing as a world, why they are paying the price of having green energies and digitization. This is one thing. But also, Gael...For example, here in Santiago, public policies are being deployed to be some sort of data center hub in Latin America. So there's a lot of data centers being built here in Santiago from like Big Tech, Alphabet, Microsoft, et cetera.And it's very interesting because many of the territorial fights that you can see here in Santiago are regarding the access of fresh water. It's about fighting the building of this huge infrastructure, digital infrastructure for example, in this year, actually at the beginning of this year, in February, I think, a court of law rescinded part of the authorization of the construction of this data center built by Google because there wasn't enough proof of the effects on the access of water for communities, how that will be affected by this huge infrastructure. And actually a couple of weeks ago, Alphabet desisted from insisting on the original design of this data center. And this, it means that they will modify and start all over again. But this is important, Gael, because it shows that people, organized people can actually fight this kind of infrastructure that is designed without seeing actually the environmental effects of its deployment, especially in terms of freshwater in this context of drought, but also in the context of the ecological and climate crisis.Pablo Gámez Cersosimo (27:15)Absolutely right.Gaël Duez (27:16)And Paz, what is the current trend in I've heard about some water quotas also for the mining industry. I've heard also that the mining industry was now building massive water pipeline to bring seawater into the mountains, has obviously a huge environmental and ecological and energy toll, but also to mitigate the water crisis. is it just one piece of news completely out of context that doesn't really describe properly what is at stake in the current train or actually is Chile getting more and more concerned about this water consumption issues and has started to regulate or to mitigate or to slow down the rising water consumption by both the mining industry and now because you've put that under the spotlight as well, the data center industry.Paz Peña (28:19)That's a very interesting question, Gael, because in Latin America, and especially, for example, in countries as Chile, we call ourselves a mineral country. We basically provide minerals to the world. So copper, for example, is a very important mineral for the Chilean economy. And now lithium, it is being really important because of this, because of green energies and because of digitization. So all our public policies are based on that extraction in terms of get money and pay everything that we need as an estate. So it's a very historical discussion are the environmental costs of mining in Chile because of this. But I will say in the last 15 years, the discussion around the access of fresh water is increasing, especially in the public opinion, because of the ecological and climate crisis that we're facing. we are now understanding that we are not going back to our earlier climate condition. Now we are living with drought for all our life. So this is a discussion that is increasing. It's a very difficult discussion to have because it depends on the economy, know, mineral economy which is why it's so important actually this kind of reports because it shows you actually who is paying the costs of green energies but also digitization in terms actually of access of fresh water.Pablo Gámez Cersosimo (30:14)I mean, without the natural resources of global south, it's no possibility to talk about digital transition or green energies. Another really interesting example, not only talking about the mineral countries in Latin America or the ones that are dealing with data centers, it is now the semiconductor industry that is taking over the region. And do not forget that this industry consumes over 264 billions gallons of water per year. And that is more than Hong Kong. And this industry needs a lot of ultra-pure water and you can find it in places as Costa Rica, for example, chosen from the Biden administration to hold Intel expansion in the region. And this is, again, one of the new debates that are taking over in the region.is this the economical progress we want to go in and with and that will cost this precious element we need to survive. put it in another way, data needs at this moment more water daily than you and me to exist.Gaël Duez (31:47)So we've covered quite a lot of the environmental impacts. We could also talk about the energy consumption. We could also talk about a bit more in details, greenhouse gasses. We could also talk about the share of electricity consumption used by the digital economy. But actually both of you at the very beginning of the interview, brought under the spotlight some very key and differentiator aspects with this report around social justice and some geopolitical significance of this report. And maybe I'd like to give you the floor now to talk a bit more about what I've understood to be some sort of a digital revolution paradox which is that those contributing the most in terms of resources, including human resources, I mean workers, are not the one benefiting more of it, of this digital revolution. I know that this is one of your specialties. Could you tell us a bit more? how you analyze this discrepancy.Paz Peña (32:52)Yeah, actually in the report you can see that UNCTAD is addressing that today digitalization is under a very concentrated market. That means that few companies actually are available to actually developed these very digital economies of the 21st century. And many of those companies are based in the US, others are in China, some of them very few are in Europe. And many of them are what we known as big tech companies. They have the power to have the infrastructure, the worldwide infrastructure to actually be able to address this need of digital economy in the world. So when we talk about digitization, for me it's really interesting to say, but who is behind that digitization? There are not many companies behind that. There are not many countries behind that.you can count the companies that are available to actually address this task. And there are a few of them, probably 20, 25 in the world. So this is the first thing that I think we need to discuss. Who is actually enjoying the benefit, the economic benefits? Yes, they are, you know, developing countries, industrialized countries of digitization, But not all the people actually. The ones that are enjoying the benefits of digitization the most is, these companies, no? Why there's this need to make everything digital is because there's a big push in terms of lobby to do that because these companies know that is where the money come from. So this is the first thing I believe is important to understand and this report will help us to understand that. The UNCTAD is addressing that there's a concentration of market in digital economy and this is a huge problem. This is the first thing. And the second thing I will say is that, as you said, Gaël the biggest question that we need to address here is also who is bearing the costs of digitization.And you can see this worldwide where there's a gap between developing countries with industrialized countries. And there's a gap there that we have been discussing in this podcast. But also we need to address that even in developed countries, there is also communities that are bearing the cost of digitization. communities that are actually being cut off the access of fresh water in, for example, Europe, etc. And also this is a question of justice, but it's not only a question of justice between developed and developing world, but also in our communities in all the world, which is something that is very important to understand.Gaël Duez (36:20)when you say, and let me be the devil advocates here. When you say, Big Tech is benefiting the most from digitalization. Does it overlook all the benefits that quite a lot of people get also from digitalization via new jobs, better services, more productivity, you name it. mean, there are countless of reports and you've mentioned at the beginning that quite a lot of them are also sponsored by the digital industry, a lot of them are biased. But I would say for the average North American or European or Japanese or Chinese citizen, believing that digitalization doesn't bring mostly valuable things would be quite hard to sell. question is, sure, Big Tech is reaping quite a lot of the benefit, at least in the global north, does overall the population also benefit from this digital revolution?Paz Peña (37:28)Yes, but that is something that you can actually discuss. how digitization is actually benefiting our economies because you can say also that you are lowering the work standards that we had before digitization, for example. You can see, and there's many reports on how digitization is influencing this trend of uberization of economy, there's no doubt that developed countries are having more benefits because they have a more digital economy.But you have to understand that today in the current state of capitalism, for many theorists, digitization is actually lowering the standards of work, for example, without even discussing all the other implications of digitization in terms oftechno-capitalism today in terms of, for example, mental health through being connected all day to social media, cetera. So this is not so clear. It's not so clear that all is benefits. But also, I think it's important to say that in developing countries, many developing countries, even I'm from Chile, so Latin America is a region that I know. In many countries in Latin America, the digital economy is not well developed yet. So when we are going through this global discourse of saying, so to be sustainable enough, we need digitization, digitization of everything. That means concretely today that the gap between these countries that are not having a digital economy well developed, that means that those countries will increase the with industrialized countries, with Europe, with Japan, et cetera. So that gap, that inequality gap is something that is not being discussed very seriously in the world. And I think, again, this and that report help us to understand that kind of new gap that we are creating with this discourse of saying, OK, we need to digitalize everything. Yes, that's maybe something good for the developed countries, but you have to be aware that developing countries are still behind that. And this could actually widening that gap, which is very, very serious matter.Gaël Duez (40:09)how would you define social injustice actually when it comes to the digital economy and could you provide one or two examples of this imbalance that you've described previously?Paz Peña (40:22)Sure, so I think we can define that... ...unjustice in the context of digitization is that... ...most of the added value created in the digital economy is captured by developed and digital advanced developing countries. many of the social environmental costs of digitization are paid by developing countries. And this is especially important, for example, in terms of mineral extraction, where the global south is basically the most affected by the extraction of minerals that are needed by the digital economy.And minerals are being extracted from the Global South, that means a lot of pollution, a lot of illegal mining, which means human rights violations of people, displacement of indigenous communities, scarcity of fresh water, et cetera. Many people, for example, say that there's no way that green mining is possible. All mining have a lot of social environmental costs. And that is something that is as important to examine. So the latest UNTAD report actually what does is to examine those social environmental impacts of digitization in developing countries, which means to not only review evidence, scientific evidence, but also have a call, an international call for countries not only developing countries, but also industrialized countries to understand the need of sustainable digitizationBut also, Gael, I just want to add something that I believe is really important to understand. It's that what we're seeing today is a geopolitical discussion where digital economy is really important. today digitalization or the digital economy is being discussed together with the transformation of our energy matrix to a more greener one. These two things, green energies and digitizations, is being discussed as one thing, as something that is needed for a more sustainable world. who is the boss in digital economy and who is available and have the capacity to have most important share of green energies in the world. So this is where the discussion is happening today.Gaël Duez (43:17)And what about the UN with this geopolitical impact? I this is supposed to be the place where nations are talking to each other. And, know, when I've read the report, I've seen all the recommendations about what should be done. And it sounded a bit like a wishful thinking list. And I was discussing it with a Green IO listener, Benjamin Davy, and he was really questioning whether the UN should or even is able to actually shift a bit from a reporting stance. This is how things are going to a more pedagogical stance and even maybe a bit of name and shame if possible, So my question is, what can actually the United Nations do about it and what actually should we do about it also?Pablo Gámez Cersosimo (44:16)United Nations UNCTAD in this case has adopted digital sustainability as a priority under the understanding the principle of common but differentiated responsibility as high relevant.It is time also to extend the calls for both actions to the entire life cycle of digitalization and to systematically track its social environmental footprint. Be aware of the socio-environmental footprint of the mechanics behind the digital economy and be aware that the problem or part of the problem can be solved with the circular design. But be aware that if we do not follow that way, we are going to deal with really complex problems in the near future. I think this is the main thing, or one of the main things of this UNTACD report.Gaël Duez (45:31)Paz what do you think about the potential for collaboration at UN level and what the UN should do about it?Paz Peña (45:39)The UN is going through a huge political crisis because of the war between Israel and Palestine and Lebanon. And also because the lack of concrete action in terms of the climate and ecological crisis we are facing through. But there's also a lot of critics regarding the UN forum and its role in the technological, digital internet governance, because mainly there's a lot of big tech influence in there, et cetera. So I think we need to be realistic and understand the political limits of the UN. There's a lot of fight inside. There's a lot of interest there. I mean, I'm very critical about that, but that doesn't mean that you can actually take these kind of reports and do your own political work as a community, as a territory, as a researcher, et cetera. I do like a lot of many of the conclusion of this report and that reports. really believe that circular as Pablo said, can be something important in terms of the designing of the digital economy. But I do also believe that circular economy is just a mitigation policy. It's not addressing the biggest problem of digital economy, which is basically this logic, this capitalist logic of extraction. This idea, as Pablo said, the idea that we have infinite resources for the economy, which is a completely crazy idea in terms of our reality, in terms of natural resources. And I don't think we can find in any report, including the UNCTAD report, a recommendation that is addressing the problem of capitalism today in digitization, which for me is the biggest problem. But that doesn't mean that these kind of reports that are designed with independent scientific science can help actually communities to understand their reality and actually start to have a more political reaction to it. So I will say, of course, I don't think the UN can do something more relevant in this issue, but I do believe that this kind of report can actually be very useful for communities around the world.Gaël Duez (48:32)So more awareness than actual actions because of the ongoing political crisis, according to you, Paz. I? Okay, got it. And my last question for both of you would be,Paz Peña (48:40)I will say, yeah, yeah, yeah.Gaël Duez (48:46)As someone working in this digital economy and many listeners of this show are actually workers of the digital economy.What can we do? How should we react to such a report? And what would be your two cents on tackling the different large issues that are highlighted in this report?Pablo Gámez Cersosimo (49:02)We need to go back to our critical thinking.And with the critical thinking, break the magical digital thinking we are dealing with.Understand that cyberspace has a growing footprint, multi-dimensional, that every time we use, we deal with our digital environment has a consequence.Paz Peña (49:38)I believe that digital workers are essential for change in digitization and in digital economies, are essential. And I actually have two concrete suggestions for workers in the digital industry. First, one of the most important is think about tech differently. try to experiment with new designs of tech that can be actually more sustainable, that cannot necessarily think in growth and growth and growth and maybe think in technology that can be used in territories with the participation of communities, et cetera. Let's try to think out of the box and believe in other tech is possible.the second thing, if you're working in a big tech company and in the industry, it's so, so important for workers to fight for more transparency in terms of the social environmental impacts of that company in different territories. fight for transparency. You are key in this. Today what we are dealing with is that companies tend to be very obscure in how they report their environmental impacts. If we can fight for more transparency, it's something that is so key not only for scientific but also for territories, for people in their territories that can actually start a dialogue with companies. And I think workers are key for that. And for me, this is the second very concrete suggestion. Fight for transparency.Gaël Duez (51:34)fight for transparency. Quite a tagline for this episode.What would be a positive piece of news that both of you would like to share regarding the ongoing trend in the digital economy?Pablo Gámez Cersosimo (51:47)I see there is more attention to the importance of the circular design in our digital world. I also see more efforts, for example, at the… European Union level to address critical matters regarding not only the circular design, but also the power of Big Tech Corporates regarding artificial intelligence.And what I'm also is a more critical thinking approach on the digital ecosystem we have, the nature of it, and the chances we have to correct.Paz Peña (52:35)I completely agree with Pablo. Five years ago, even three years ago, you didn't see many news in the outlets around the social environmental impacts, for example, of AI, of the digital economy. Today that is completely changed, I think.There's also a lot of critical thinking or more critical thinking around digitization, but also that means there's a lot of territorial movements saying, know, these digital technologies have a very concrete material impact in our realities. That means that there are people, not necessarilypeople that is related to tech, but people in their communities saying, you know, let's discuss about this. And this is something that you can see in the media outlets. And I think that is very, very positive because that means that people is alive actually, know, trying to change and to have a better world, a sustainable world, even in digital technologies.Gaël Duez (53:49)thanks a lot, both of you for highlighting the rise in awareness, at least in our industry. And let's hope that it will have some impact at some point, but awareness is always the first step. And this is a very reason of this podcast as well.And yeah, it was really nice to have you both of you on the show, not talking the regular green software or responsible AI topics, but zooming out a bit and discussing massive geopolitical and social issues. So thanks a lot, both of you for this.Paz Peña (54:12)Thank you, Gael, for the invitation.Pablo Gámez Cersosimo (54:20)thank you very much for make this space possible. And this is also really positive to mention the attention that you are giving also to this issue. Thank you very much.Paz Peña (54:30)Yeah.Thank you and so nice to see you, Pablo.Pablo Gámez Cersosimo (54:39)That's it. Bye!Gaël Duez (54:44)Thank you for listening to this Green.io episode.

#48 - Greening the video game industry with Ben Abraham and Maria Wagner

3 billion gamers worldwide, billions of devices, terabytes of data streamed, the gaming industry comes with pretty big numbers starting with its $455 billion sales in 2023. Is its environmental footprint as big? (Not) fun fact, not a single executive in this sector could answer the question. A new non-profit initiative, the Sustainable Gaming Alliance, is trying to get these numbers right and to equip the industry with the right framework. Its Managing Director, Maria Wagner, and its Research and Standard lead, Dr Benjamin Abraham joined this Green IO episode where great insights were shared on:👿 The periodic table of torture for gaming device,🖼️ The Gaming industry dependency on graphics to boost its sales🕹️ Why “this game is beautiful” should be replaced as a praise by “this game is so enjoyable”📋 Why GHG protocol is not adapted to the gaming industry🌋 How to shake up a multi-billions industry in 10 weeks ?🔄 Why the project mode in the game industry - and elsewhere? - doesn’t help a GreenOps culture to flourish😴 Energy consumption at idle state❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode, twice a month, on Tuesday!📧 Once a month, you get carefully curated news on digital sustainability packed with exclusive Green IO contents, subscribe to the Green IO newsletter here. 📣 Green IO next Conference is in Paris on December 3rd, 4th and 5th (use the voucher GREENIOVIP to get a free ticket) Learn more about our guest and connect: Ben's LinkedInMaria’s LinkedInGreen IO website Gael Duez's website 📧 You can also send us an email at contact@greenio.com to share your feedback and suggest future guests or topics.   Ben and Maria's sources and other references mentioned in this episode:The Sustainable Gaming Alliance Website The SGA youtube channel (with recorded workshops and interviews) The SGA discord channel SGA - How it all started: 10 weeks to save the games industry Greening the Game Industry, Ben’s newsletterBenjamin’s book “Digital Game after Climate Change”Wattwise the game jam dedicated on the energy consumption of video gamesGodot game engineUnreal game engineDigital Collage workshopNature article on climate protests Giovanni’s Celeste gameThomas Beaufils’ newsletter “Tales from the Tech”Signatories against gaming in MetaverseTranscript (automatically generated)Ben (00:00)the idea that the gaming industry globally has a footprint probably the size of a country like Sweden.was just on no one's kind of radar.

I'm Gael Duez and in this podcast we empower responsible technologists to build a greener digital world, one byte at a time. Twice a month, on a Tuesday, our guests from across the globe share insights, tools and alternative approaches enabling people within the tech sector and beyond to boost digital sustainability. And because accessible and transparent information is in the DNA of Green.io,All the references mentioned in this episode as well as the full transcript will be in the show notes. You can find these notes on your favorite podcast platform and of course on the website greenayo.tech.I'm all in mushrooms at the moment. This is how a few months ago Giovanni Celeste started to describe his new game. He kept on. They're incredible and you can tell great stories with them. Of course, to be more mainstream, the first part of my new game is about bees. But I'll do scenes with mushrooms. Giovanni is a pillar of the small but vibrant gaming sector in Réunion Island where I live.He crafts games focusing on the ecological transition. He works either with a small team or by himself. He's what is called an indie developer. Before our discussions, I hadn't realized how diverse and complex the gaming industry was. For me, it was mostly massive studios delivering entertainment to more than three billions of gamers worldwide.or discussions, reactivated a question I had in the back of my mind for some time. How is the gaming industry doing with its environmental footprint? With massive data transfers, billions of devices sold, and all of the computing power used to develop and run the games, it cannot be negligible. Thomas Bouffis, from the Tales from the Tech newsletter, pointed out to me several signs showing a modest interest in the sector.Starting with very few C-level offices exclusively in charge of sustainability in the main studios. Sure, here and there some initiatives are emerging such as a petition against developing games in the metaverse, the ongoing work of the French agency ADEME on a referential for sustainable gaming, or what was the active game jam on the energy consumption of video games.Still, most of the buzz is about the gaming industry helping to raise awareness on climate change and ecological transition, almost nothing about its ownThis is where Giovanni told me about the Sustainable Gaming Alliance. And voila, I eventually found experts to discuss the gaming industry environmental footprint.Maria Wagner and Dr Benjamin Abram respectively the SGA Managing Director and SGA Research and Standard Lead kindly agreed to answer my questions about the footprint and more importantly what a tech worker in the game industry sector should do about it. Ben has written an entire book on the topic digital games after climate change based on his PhD work. Maria's personal story could be the scenario for a video game.Before becoming a seasoned actor in the gaming industry, she worked in diplomacy, intercultural conflict management, as a political observer in Syria, or ran a refugee camp. Wow,the perfect fit to run a global multi-stackholders initiative to green a 455 billion dollar market.Gaël Duez (04:00)So welcome Ben, welcome Maria. It's great to have you on the show today.Ben (04:06)Thanks, Gael. It's great to be here.Maria Wagner (04:06)Thanks for having us.Gaël Duez (04:09)You're welcome. Just to understand a bit the context before deep diving into the environmental footprint of the gaming industry and the many, many, different topics that I'd like to cover with you. What makeGaël Duez (04:24)The gaming industry is so specific within the tech industry. And how come that we usually don't incorporate in the big green software, green IT, sustainable IT, you name it, momentum, which is happening around the world, what is related to the gaming industry itself. And as I said in my introduction, the gaming industry is pretty big, both in terms of a number of gamers, employees and workers.So I guess in terms of footprint as well. Maria, you're a very knowledgeable person of this industry. Could you maybe try to give us an answer?Maria Wagner (05:00)Yeah, I think the games industry is very special when it comes to the connection to the people and of course also the reach, right? As you have said, we are reaching basically half of the globe and this is something which a lot of people forget that we are the medium ofthe times. So compared to movies and films or the TV, there is no other medium which reaches so many people and I think this makes us really special.Gaël Duez (05:33)It's a question of reach according to you more than the technical setup behind it.Maria Wagner (05:38)The technical setup behind it, of course, as well, I would say it's way more complicated because it connects so many different parts when it comes to games. There are so many parts which need to come together to make a game happen and this is maybe something also Ben can cover perfectly because he looks into the value chain.Ben (05:55)The thing that separates the game industry from just general software and tech to my mind is that it is a software industry, but it's also an art form. It's an art industry. it's both artistic practitioners who work with digital tools. So there's like 3D artists, there's also coders, there's also community managers. There's a really strong emphasis on engagement with the end users.Games companies are very aware of what their users are interested in and care about. And so it is just a software company. Games are just a software development exercise, but they are also an artistic exercise as well. There's a creative dimension to it.Gaël Duez (06:47)Which makes them pretty specific, I would say, because I've never heard about a piece of SAP reporting being branded as arty.What about its environmental footprint? We're talking about billions of users. We're talking about hundreds of millions of devices worldwide. So I guess it's pretty big. I couldn't really see any global report onthe environment and footprint of the gaming industry. So maybe that's an issue that we should discuss a bit later in the episode. But what are the numbers or the order of magnitude that you could share with us to grasp how much is the gaming industry impacting the planet?Ben (07:29)So in terms of orders of magnitude, I think that's the right question to ask because we really only have a rough sense. It is in the tens of millions, almost certainly. Is it less than a hundred million? Possibly. When I started the research work that became the book that I wrote, Digital Games After Climate Change, there washardly any kind of research out there. I couldn't find anyone who was even really thinking about what the impact globally of the games industry was in terms of emissions at any rate. There was a bit of awareness of things like e-waste, resource consumption, that, know, vaguely there's this thing called the cloud that's probably not great for the environment. But the idea that the gaming industry globally has a footprint probably the size of a country like Sweden.was, was just on no one's kind of radar. and so My best guess is that it's somewhere in the tens of millions of tons. The disclosures that I've added up over the last couple of years from the biggest game companies in the world point to a figure somewhere around about 20 to 50 million tons per annum. And that's just, just playing games. That's players that's.infrastructure, making the games themselves, offices, it's everything. the complexity of it really does sprawl.Gaël Duez (08:54)And Ben, you're mentioning to greenhouse gas emissions when you mentioned talking about millions. That was the main focus of your study in terms of environmental impact. Am I right here?Ben (09:05)It was, yeah. So I, I tried to break down the production process into different phases and looked at what is involved in each phase. So developing games, it's a lot of power in offices, it's IT purchases, new equipment. distributing games involves data centers, the digital distribution networks of steam, the Apple store, the Google play store, you know, all these devices that are getting games downloaded to them.And then the end users themselves and the devices that they play games on, whether that's a games console or a PC or a smartphone. And each one of them has vastly different levers of decarbonization potential and vastly different levels of transparency even in terms of what we know about each phase.Gaël Duez (09:56)And did you manage to calculate also the embedded carbon or was it only carbon emitted by the energy consumption or alsothe carbon emitted during the manufacturing and extraction phase, so through the entire life cycle of all the devices.Ben (10:14)So I did also look at embodied carbon and I also actually looked at a little bit of the other non-climate environmental impacts, so things from like mining rare earth materials and things like that. So actually in my book, there's a really interesting table, like I call it the periodic table of torture, where I go through a list of elements that were detected via this advanced ICPMS method.of analyzing what are the atomic elements inside a PS4 chip. And I go, okay, well, what are they probably doing in there? Where do they come from? What are they used for? Are they part of the transistors? Are they part of some other part of the lithography process? Yeah. And so when it comes to games consoles, at least, companies like Microsoft and Sony have gotten a bit better over the years at disclosing what the embodied carbon is in those.consoles. So we know a little bit about them, but PCs, because there's so many device manufacturers, there's so many different hardware components. Yeah, again, that's just this big question mark unknown area.Gaël Duez (11:18)That's interesting because you mentioned embedded carbon, so everything related to greenhouse gas emissions, but you also touched upon the material footprint, which is how much we need to extract to get one piece of console or chip to be manufactured.When I facilitate digital collage workshop, that's a figure we use a lot, which is basically for two, 300 grams smartphones, we need to extract around 70 kilos of resources. this ecological backpack is pretty big. Do you know if this is this same order of magnitude for a console orCan it be a bit smaller?Ben (12:00)It's a really hard question to answer. My suspicions are that they're about the same.I don't have any hard numbers exactly, so my study was done on the smell of an oily rag. I had no money to do it and my research lab couldn't actually tell me the exact quantities that are in them. it's a good guess that most games consoles are probably equivalent to like a smartphone.Okay, well, that's pretty big. It's a ratio in terms of hundreds times more than the actual weight of the device. pretty good. Maria, are there other environmental impacts that the gaming industry is starting to get aware of?Maria Wagner (12:37)At the moment we are in the phase of raising awareness in general when it comes to the footprint of the value chain and really producing games because I think there is a big focus when it comes to the reach and what people can communicate through their games. when it comes togetting their own house in order and looking at the value chain and decarbonizing the value chain itself. There we still have a long way to go.Gaël Duez (13:09)I think I'm going to hire you to explain to everyone why this podcast is about cleaning our hand house rather than doing green tech or tech saving the world, etc. That's exactly the approach I've got. Okay, so before deep diving into the industry and more specifically a tech worker in the gaming industry can do, I've got one questionSo as a gamer in my personal life, are there some things that I should specifically focus on to reduce my environmental footprint? Maybe Maria, do you have some idea?Maria Wagner (13:46)you can look at your electricity grid. So where do you get your electricity from is a huge factor. And of course, you also have to ask yourself if you always have to have the newest hardware, which is out there, or if it's possible to play your favorite game, maybe on like an older device.Yeah, so I think this is something what players can do for sure. And of course, being more vocal about it. Ask your favorite game studios about their footprint and responsibility and the same goes, of course, also for the hardware.Gaël Duez (14:24)Regarding the devices, what is the churn rate? Smartphones used to be crazy. the average use span of a smartphone used to be a year and a half. So people were literally dropping perfectly functionable devices to get the newest one. It gets a bit better since a few years. I think it's a bit above two years, which is completely insane.And you think about all the energy and materials and resources put into this incredibly sophisticated device. anyway, I've heard that the gaming industry, the console, people tend to use them a bit longer. So how much the device is something that we as gamers should also focus on? Or how much is it more about energy consumption, as you mentioned a bit before?Ben (14:48)It's still so short, yeah.Maria Wagner (15:16)I mean, this is a question or this is a topic we actually discussed, I think, just like last week. So, of course, it takes up a lot of resources to produce new hardware. So I think we should in general question our culture of...having software which always needs new devices, know, so basically adapting the software in a way that we can still use the old devices and it still would run perfectly. So it's hard to say because of course if we would use hardware way longer then it would be more an energy question and optimizingthe software to use less energy. But as long as we keep pushing the boundaries and need always new hardware, this is still a big question.Ben (16:15)Maybe I'll just add a little bit extra context or a little bit extra color there then. The games industry has been basically since the 1980s, it's relied on selling games or marketing games via a kind of approach thatthat sells based on graphics, right? Like this, it's slowed down a little bit in the last five to 10 years, but for the longest time it was like, you know, it went from eight bit graphics to 16 bit to 32, and then you get polygon counts, resolutions, frame rates. And so that's been kind of embedded in the games industry for a really, really long time now. The expectation is we're going to sell games by saying, ooh, this year's model is better.There's more polygons or it's, you know, it goes up to 200 frames per second or it's more responsive or it's got this new engine or that new feature. And that drives the hardware upgrade cycle. So even though console generations, so if we're just talking about console gaming last for somewhere between six, seven, maybe eight years at the very most in terms of like, you know, a new one comes along and it's upgraded and better.Usually what ends up happening is we get these mid cycle refreshes where you know get the ps4 pro or the ps5 pro or you know these upgraded ones Yeah, so basically the games industry has been locked into the hardware upgrade cycle for a really really long time And we're really really reaching the limit of that in in the last year or so The games industry has been through a real shake-up. It's been through a real crisisIt's because production costs of making games has been so high because of this churn of graphics and visual fidelity that just means you need to throw more and more artists at the problem, more and more 3D modelers, more and more texture and all of this sort of stuff. And that's to sell more consoles, to sell more games. And that's part of this unsustainable trajectory that we really need to rein in.Gaël Duez (18:21)And you know, Ben, it super interesting because I remember that when I used to magazine, yes, paper magazine on games, the best way to praise a game was, is beautiful. It is an interesting choice of word. Like, it is a beautiful game. And it was,As you say, a lot based on graphic and not necessarily how enjoyable it was to play with this game. we could have expected a journalist wanting to praise a game saying, it's incredibly gameable or enjoyable to play with, or it got many twists or you get completely hooked by the story.That's true that most of the time it's all about how beautiful, how well crafted, how pixel perfect the game is. I think it has started to change a bit in the industry. it was really something that struck my mind when you mentioned it, this vicious cycle of always more hardware. to wrap up what you both said for a gamer, it's really about...questioning the need for the latest shiny stuff and considering keeping the hardware longer and make sure that the electricity grid is as decarbonized as possible, especially, I guess, if the person plays a lot via streaming solutions. Am I right to summarize it that way?Maria Wagner (19:47)I maybe would also just add there are so many beautiful games out there which don't have like the craziest newest like graphic and the craziest needs when it comes to hardware and this is something which we need to cherish and I think it's just like as you said before a marketing question thatespecially like the big corporations is on the shiniest versions and like the games which need a lot of resources but there are also games out there which are completely the opposite and are beautiful as well.Ben (20:25)Just to add on to that as well, I think one of the things that I want to emphasize too is that this is what we know at the moment, right? So the ability for consumers to actually affect their end emissions when they're playing games is actually quite limited, right? A lot of the power is in the choices that have already been made by people upstream, by big corporations, by big companies.will be things that consumers can do. And that's sort of what I think needs to kind of happen. And what we're hoping to do with the SGA actually is to get the whole of the industry, consumers, producers, fans, know, even people who hate the games industry, all to be on the same page about, where do the biggest interventions need to happen? Where do we get the most bang for our buck?Gaël Duez (21:19)Ben, what a wonderful transition. Let's talk about the gaming industry itself.So maybe it's time to talk a bit of, first of all, as a worker in the IT industry, sorry, in the gaming industry.How much am I exposed to the fact that I'm also part of the problem and I emit greenhouse gases and I consume a lot of non-renewable resources, et cetera, et cetera? What is the level of awareness in the gaming industry at the moment?Maria Wagner (21:49)Yeah, I mean, this is exactly the question which, like one of the other co-founders, Jiri Kupjainen and I was asking ourselves when we did our 10 weeks to save the games industry tour, where we really wanted to interview the leaders of the industry and just find out what is their knowledge level on this topic. so...Maria Wagner (22:14)like we interviewed around like 40 industry leaders within 25 cities and found out that they don't know anything about it. most of the people,Maria Wagner (22:30)A lot of people think that because games are digital that they are automatically green or that they say, okay, compared to other industries, we don't have such a huge footprint. So we don't need to focus on that, which is of course crazy because we don't have any data.Gaël Duez (22:51)The level of awareness seems to be very, very low, even compared to other subparts of the IT industry. mean, usually, the, it's in the cloud, so it doesn't pollute anymore.It's something a bit of the past now in the IT industry. That was something that you could hear maybe five years ago, but not that much today.Gaël Duez (23:10)So you mentioned the Sustainable Gaming Alliance and I guess you created the SGA as a reaction when you realized with Yuri and other people that the level of awareness was super low. Could you tell us a bit more about this organization? Why you created it and how is it helping to contribute today to a greener, if I may use the word, gaming industry?Maria Wagner (23:33)Yeah, basically, before founding the Sustainable Games Alliance, I for my part was leading the Games Forest Club, another NGO, was helping games companies to donate to forest protection. And there I realized very fast that a lot of companies usethe forest protection or planting trees as a way to, you know, think of themselves that they're done their part and being green. But the problem is, of course, that they never looked at themselves and at the value chain. So they did not understand that they need to decarbonize and need to, yeah, really basically change the way they're doing business.to be sustainable. So in the conversations which we were having together with Jiri, found out that we need numbers. We basically need numbers to be able to address this topic. there are no comparable numbers at the moment. At the moment, every company can just like...publish and say whatever they basically want, what their current footprint is. And this is something we want to address because like only with comparable numbers, we will be able to talk about best practices and how to optimize and yeah, more efficiently reduce the footprint and decarbonize the industry.Gaël Duez (25:02)Maria, there is something that I don't understand. Most of these companies, they are pretty big. they already, they should already report carbon audit. mean, especially if they're European based or even in some states in the US, you've got now compulsory carbon reporting following GSG protocol or other protocol in France. So how come that the numbers are not comparable?Maria Wagner (25:08)Yeah. It's because these reports are based on the greenhouse gas protocol so far. mean, there is the corporate sustainability reporting directive in Europe, which is based on the ESRS. But the problem is it's not game specific. So basically, when you do your reporting, the framework and methodology is so vague, it leaves so much room for you to make decisions andadapt your numbers, that in the end you get non-comparable results. for example, up until now, companies could leave out category 11, the use of the product. And it's like in gaming, a huge part of the mission.Maria Wagner (26:15)If companies leave this out, the numbers are not comparable.Ben (26:18)Yeah. The reason I think that a lot of that happens is that again, because games like they like the games industry relies on these larger tech platforms. Like there's not a lot of direct to consumer sales of games, right? It all goes through the steam or the app store or that's about it. Really. There's no buying a game directly from the producer. Usually there's like a platform between you.And so what that's meant is that most of the companies have been like, well, I didn't design the Xbox. I didn't design the PlayStation. So that energy profile is like outside of my control. So I guess they just decide, and this is like open to them based on the interpretation of the greenhouse gas protocol that yeah, use for sold products. That's not my responsibility. It's actually the console owners responsibility. like Microsoft's or Sony's responsibility.It ends up with this situation where there are large parts of the games industry that are number one, just not being added up, they're not being calculated properly. And then number two, we have no plan for how to reduce them. No real actionable strategy for how to get to net zero in the games industry.Gaël Duez (27:26)There is no in the SBTi framework any specific guidelines for the gaming industry. Not at all.Ben (27:37)I don't believe so, no.Gaël Duez (27:38)And could you share another example? Is there any discrepancies or way of calculating that creates so incomparable reports?Ben (27:52)well, I think a lot of it just comes down to it not being a practice for lots of games companies, right? yes, it is quite surprising that a lot of the big companies aren't disclosing, that is changing over time, but, quite a lot of the biggest game companies, if you think about like Nintendo, based in Japan, Japan doesn't yet have a mandatory,reporting standards. Nintendo actually does disclose quite a bit, but there are lots of other Japanese games companies, South Korean games companies, North American games companies as well that it's just not, hasn't been on their radar. No one, guess, has really asked them to do this reporting yet.Maria Wagner (28:32)Maybe one more thing is, so the problem is there are so many different components within the value chain. I think this is something which is really special that the greenhouse gas protocol does not provide the boundaries between the different service providers. So we have, for example, ads, right? Like if you have a mobile game and it's free to play and you have all the ads.which are played during the gameplay. There is no clear definition of who is responsible for the emissions of this ad which are played during your game. And this is just like one example of how many different companies are involved within the value chain. And because the boundaries are so unclear, you have completely incomparable numbersBen (29:25)And the same goes too for game engine makers. most modern games are made on a software platform. They're made in Unity or they're made in Unreal. And so there you go. You're like, OK, well, I don't have control over Unity. I don't have control over Unreal. Is it really my responsibility to do something about the efficiency of my software? Or what are the levers that I even have? It's not visible within any of them yet.you know, what you're actually asking of your end user and their energy consumption, you know, and this could be millions of people that you're potentially selling and playing your game.Gaël Duez (30:02)That's a beautiful example, Ben, because I've done a bit of research and actually there is a third solution named Godot. And that's a bit insane without any piece of data, I think it's something 60 gigabytes of data just to install Unreal.And then you've got this other game engine called Godot, and it's 160 megabytes. So it's just insane the difference.So it seems that for a developer working in the game industry or a small studio, there are some leewayOr am I completely misunderstanding the issue here, Ben?Ben (30:45)No, I think that's right.It's hard to know exactly because it's just never been part of the culture to really think about the performance. I mean, it has been for specific platforms. Like you need to hit your target. You know, maybe the new call of duty will have a frames per second target of 60 frames per second on, you know, this specific kind of hardware thing. And so they will always like push the limit right up to their, you know, squeezing as many pixels and stuff as you can.But yeah, there are absolutely alternatives that use less space, less power, less like resource intensive, less taxing on the player's device. And, you know, if you just take a different artistic approach, you take a game development methodology, basically, you you develop something smaller, you're not making a big blockbuster here. If you're an indie developer and you're working in a small team,You don't need all the features of Unreal. You're not going to need them all.Maria Wagner (31:44)I I think this is also like the exciting part of our work that because it's so new to the industry, there are so many low hanging fruits and potential because like people just have not looked into this topic much. And yeah, that's the exciting part about it.Gaël Duez (32:02)How easy do you believe the change in mindset will be?Ben (32:05)I mean, it's partly mindset, but it's also partly the business model that the games industry has used and relied on to sell games. that approach to marketing the game as being the newest, biggest, brashest, most advanced game andyou know, selling a new game every couple of years, right? And you're, moving on to the next project, you know, as soon as your game is out, at least until fairly recently when with the advent of games as a service, a lot of the games, you know, they would just get shipped and then you start the next project immediately. So there's nothing really to optimize or there's no chance even to, to optimize in the development cycle for saving money in the servers, unless you are running a game like Fortnite or something with big servers. And then, yeah, that's, think where it's probably starting to happen.Gaël Duez (32:59)And where things are starting to move, because you mentioned several times the business models, but we talk more and more about streaming game. We can also see that some, maybe a fraction, I don't know how big it is, but of the gaming industry is focusing or refocusing on the narrative, the beauty of the story and the beauty of the gameplay rather than the beauty of the game itself. So.Are these trends potent or are they still marginal? And what is changing in the industry that could positively impact the reduction of its environmental footprint?Maria Wagner (33:36)I think actually that the industry is getting more mature at the moment because of the problems it has been through or is still in. I think before the eyes were also not on the industry that much. So there has been this discussion within the industry, are games political?or not, you know, do we have a responsibility as game developers to be political? And I think it also goes into do we have a responsibility to decarbonize or is this up for our service providers and the politicians to deal with that topic? And I think at the moment there is a change that the industry is getting more more mature and is ready to take on more responsibility.Just because we have on the one hand the regulation and also politics are getting more and more interested in games and what is going on on the platforms. yeah, I think also the society is now a little bit more aware that that the games industry is a huge industry. And before...they were able to just be something on the side and be not heard of.Gaël Duez (34:55)It's the number one media today, maybe with video streaming, but I'm not even sure. think video gaming is bigger than video streaming. And just to bounce back on what you've said, I've never heard about a single cultural product which is not political per se. By not willing to be political, it is political, it means that it's just conservative. And I guess if you look at the story of Call of Duty,Gaël Duez (35:22)It's just a living recruitment ad for the US Army and it has been copycat by almost all the armies around the world for recruiting purpose. So it is very political what you put in the game.So let's play a game, pun intended. Let's say that we are a team of a small indie studio, because big, big cooperation, it's a different story. And we are, I don't know, 20, 30, 40 people in the room. And we are brainstorming And we're saying, OK, what are the top three thingsthat we should consider changing or we should consider start doing to truly make our games sustainable.According to you, would be the three things that a small indie studio should consider?Ben (36:16)certainly I think the top one is to support older hardware because that's the big challenge, right? A lot of the games industry, we have the solutions, we just need to kind of implement them so we can buy renewable electricity and we can run our servers on renewable electricity.do digital downloads renewably as well, but when it comes to hardware, that's just always going to have a huge emissions and huge other environmental footprint attached. doing things to opt out of the hardware upgrade cycle to make devices last longer, I think is the number one thing for a small team to do.Maria Wagner (36:57)I actually would agree when it comes to that and my number two would be get in touch with other studios who are already working on the topic because like I still think that at the moment the industry is barely connected when it comes to sustainability and games and there are a lot of great examples out there.And of course, yeah, like talk to us because we can provide you with the tools to measure your impact.Gaël Duez (37:32)you mentioned several times the framework or actually the tools that the SDA can provide to anyone in the gaming industry to help get better measurement or calculation. you want to say something about it.Ben (37:49)Thanks Gael. at the SGA our main mission is to produce a methodological standard for how we measure, how we collect the data and how we calculate the end greenhouse gas burden of making games, of playing games, of selling, distributing games, the whole value chain.we're working on this standard and it's going to be an open source standard. It's going to be open to anyone to use and apply. And we want as much input as possible. Like we're already consulting with lots of games companies. The goal of it really is to just save everyone a whole bunch of time, right?Gaël Duez (38:28)And is it more a tool or a or a framework? Is it like plug and play? That's my first question. You know, you've just dropped numbers from, I don't know, your accounting system or wherever you need those numbers from. Or is it more something that you get your own people trained to understand how to apply this methodology into your company?Gaël Duez (38:53)That will be my question number one and my question number two, because it might be a bit related, is how connected is this work that you're doing with the GHG protocol or other, I would say, meta protocol or meta way of measuring the footprint?Ben (39:09)So it is a little hard to describe because it is a work in progress. We obviously have massive big vision for it. We want it to be like the kind of plug and play thing. You can just like connect it up to all your existing systems. But at the moment, it's just a set of methodologies and some spreadsheets that I've made to kind of test the methodologies and.and work as a tool for people who maybe don't have anything to use at the moment.Maria Wagner (39:36)I mean, basically, our goal is to help the games companies to comply with CSRD. So the methodology sits on the baseline of the greenhouse gas protocol and the ESRS. So it is basically helping the games companies to understand all this blurry lines.which the greenhouse gas protocol leaves open at the moment. So what we are doing with this at the moment spreadsheets and supportive numbers is that we reduce the time and efforts of the companies to doing the research themselves and also to be alone making this decision, decisions which are going into the reporting.For example, what is material for my studio? This is something which you cannot put into a spreadsheet or a calculation. This is something which you need to decide case by case. And what we are doing is we helping the industry to have this conversations and decide basically what is material and what is not. So they're not alone.At the moment, this legislation is still a moving target. So it would be stupid to now develop like a tool, right? Because it would be outdated in two months. So it's kind of a moving target. And we are offering a community with experts discussing all these topics. like this poor...reporting sustainability managers are not alone having to make these decisions, but that they can basically connect with each other, exchange knowledge, and in that sense, save themselves time and share best practices.Gaël Duez (41:30)So I've got a better understanding of what is currently offered by the sustainable gaming aliens and the big vision I would say. So thanks a lot both of you. I think we have some sort of an action plan now with the brainstorming exercise plus the explanations you provided with the SGA methodology.Maria Wagner (41:53)And when it comes to the story, I...wanted to add on that a little bit. Of course, it always depends on what kind of game you're developing. But sometimes the stories within games are very focused on extraction of goods. I think game developers should just like, but I think most of the game developers do, just be more aware of what kind of storydo you convey to your players? Does it always have to be gather everything and throw it away afterwards? Does it need to be this extraction? Because there are already more and more games which are keeping that in mind, that there is always a cost to extraction. But this is something which is quite new, I would say.Gaël Duez (42:47)Yeah, we should create an extension to Age of Empire, where actually when you ran out of mine, you know, and especially gold or whatever, it's not like stable because it happens, you know, I was always very shocked when I used to play with this game that, okay, it's over. You know, we collected everything on the map and it's over and you stay at the same level of civilization and it should be like an immediate drop back to...prehistorical age, like you don't have the gold to pay whatever the resources are. Boom, end of game, end of civilization. But I got your point that the philosophy of being a bit more aware of how our biosphere works and that it's not just extract, extract and strike and then the game is over because actually in the real world, we don't want the game to be over.Gaël Duez (43:39)Ben, you want to add another action?Ben (43:42)It's probably a little bit less relevant for small indie studios, but it's still something they can do. it's actually something that the Microsoft Xbox sustainability team pioneered. So what they realized is that there is a lot of waste in games, a lot of wasted energy. When players are sitting on a menu screen because they're in between rounds or they've gone off to make acup of tea or get some food or whatever. You don't need to be pushing all those pixels on a idle state, right? So, and they worked with a couple of different studios, big studios, small studios. And they realized that, yeah, if you just shave a few frames per second off the menu screen and you lower the resolution,you can save a substantial amount of power from that device while it's in that state. And I think the result for Epic Games who make Fortnite was in the order of megawatt hours of power a day, just from this one change. So if you've got a really big audience, you can make a big impact.And that's pretty amazing because it's user aware electricity consumption. Like if no one is actually using the game, no need to consume crazy amount of energy if I follow you right here. But could we envision a word when we move a step forward with carbon aware? Like if I know that my electricity grid is highly carbonized at the moment because of the time of the day or because where I am, I will...offer my user to maybe play with a lower quality or resolution being a bit degraded Or is it something that at least at the R &D stage, like not being rolled out already, is something considered on it's a bit of a taboo, like all the time best services ever should be delivered to our user?Ben (45:38)I think it's possible. It's definitely achievable. I think the barriers there are actually just cultural. is like, we've always got to have the most powerful, most beautiful image. And we are starting to see attitudes in gamers change. A bit of research done in 2021, think, asked gamers, a thousand gamers in the US, likeBen (46:04)a whole bunch of climate and sustainability related questions. And even then, a majority of them said, yeah, the games industry has a responsibility to reduce its emissions. So I think players are starting to be aware of this. it's up, it's at the point where we just need to connect those desires with the solutions that developers already have.Maria Wagner (46:26)I'm just thinking, it wasn't the eco mode version, like the Fortnite event, what they did. I mean, it was playing with reduced frame rate, as far as I know, but there was no study done how the players received it, right?Yeah, I'm not aware of, I can't remember what was in the white paper. They have a published white paper that you can go look at and see. But I think the goal mainly there was to be as unobtrusive as possible. It's really not a thing yet in the games industry to connect with those gamers that do have those green impulses and make use of them.Maria Wagner (47:12)Also, sorry to add on that, I definitely think that there is the potential and for like an indie game studio, in that sense, I would say the number one thing would be to get together with others and put pressure on the big service providers, the platforms, or not pressure, but like working with them together to decarbonize the whole industry.Because I think if we see the big picture and we have comparable numbers, it will be way easier to decarbonize as a whole industry than one studio doing little tweaks.Gaël Duez (47:51)Before closing the podcast, know that you've already shared some resources, but is there any other resources on top of the SGA and your book, Ben, that you'd like to share that could be very, very useful for a tech worker in the gaming industry?Maria Wagner (48:07)I think at the moment we are also shooting a bunch of different interviews with industry experts. And I think it's actually interesting to hear what is happening there. So this is definitely something I encourage people to look into because we are interviewing the different sustainability managers with their challenges and solutions within the industry.we are really coming from the industry and the solutions we design are for the game developers, like really for people working at the games and which will be applicable. like Yirik Kupyainen, who is one of the founders and had won the ideas, is an engineer himself. He had a bunch of likeMaria Wagner (48:55)companies within the industry. also, Petri Jerviletto is one of the co-founders of Remedy, who is backing us. And of course, also David Helgeson, the founder of Unity. So we are backed by industry experts.Gaël Duez (49:15)So thanks a lot for these extra resources and extra explanations on what you're trying to achieve with the SGA. Now, traditionally, and this time I will make no exception, I love to close the podcast with a positive note. So I would like to ask both of you, what is the positive piece of news that you would like to share regarding sustainability and maybe even sustainability in the gaming industry?Ben (49:41)well, yeah, so I was really encouraged by the recent publication in, think it was a nature journal, looking at the effect of what, I guess what we might consider the more extreme climate protesters was on public sentiment. I think they ran a study on the public public opinion after like before and after the just up oil intervention that I think threw some soup on the, on one of those artistic works.And the result was actually that rather than like harming the cause or anything actually it the support for more moderate climate sustainability action rose after those sort of extreme interventions. So I thought that was really encouraging. It just made me want to like go out and do the Andreas Malm thing and blow up a pipeline.Maria Wagner (50:31)Yeah, I think it's very encouraging to see that more more companies are reporting on their scope three emissions because of course on the one hand they have to anyway because of the European regulations but it's encouraging to see that also a lot of companies doing that like out of free will.and that we get more and more data within the market. And because of that, it is also more and more clear that we need to have more refined methodologies and that we are basically all connected because I think many times we think we can sweep over the responsibility to someone else. But when it comes to solving climate change or decarbonizing the industry,It's really about working together. yeah, think, yeah, seeing more and more companies disclosing their scope three emissions is something which will help to recognize that.Gaël Duez (51:34)So transparency in working together. I think that could be the tagline of this episode.Maria Wagner (51:39)Yeah, yeah, yeah, actually, yeah.Gaël Duez (51:42)So thanks a lot both of you for joining the show. I think I will very carefully consider which kind of device I will buy to put under the Christmas tree.As I said in the introduction, that's a sector I absolutely have no clue on how it works. So I learnt a lot thanks to both of you. once again, it was great to have you on the show and I hope that we will keep on having a very interesting discussion.Ben (52:07)Thanks, Gael.

#46 - Green SEO with Natalie Arney and Stuart Davies

🔎 Green SEO? Not the most widespread concept in the sustainability field. Still, seasoned web designers and developers know it well: folks in charge of SEO often have the final say when it comes to content, design and even sometimes technical choices. And on top of this influence, SEO practices also carry their own environmental footprint being very data hungry. 🎙️ In this episode, Gaël DUEZ invites two seasoned SEO practitioners and pillars of BrightonSEO - one of the world’s top conferences on the topic - Stuart Davies, founder of the Ethical Agency Creative Bloom, and Natalie Arney, an SEO Consultant with a knack for sustainability to explore Green SEO.Some Takeaways:↔️ the transversality of SEO functions,💻 the alignment of the core web vitals with sustainability goals,🌐 The importance of choosing sustainable hosting providers,♻️ Practical sustainable SEO practices, and much more.❤️ Subscribe, follow, like, ... stay connected the way you want to never miss our episode, every two Tuesday!📧 Once a month, you get carefully curated news on digital sustainability packed with exclusive Green IO contents, subscribe to the Green IO newsletter here.  📣 Green IO Paris is on December 4th and 5th 2024 --> use the voucher GREENIOVIP to get a free ticket! Learn more about our guest and connect: Nathalie Arney’s LinkedInStuart Davies' LinkedIn Green IO website Gaël's website 📧 You can also send us an email at contact@greenio.tech to share your feedback and suggest future guests or topics.   Natalie and Stuart's sources and other references mentioned in this episode:Search Engine Land’s interesting study among SEO folksGreenSEOJean-Christophe Chouinard’s blog Core web vitalsGreen Web FoundationScreaming Frog SEO Spider Update – Version 20.0 GreenSEO Meet-Up Green SEOTranscript Gael Duez 00:00Hello everyone, welcome to Green IO! I’m Gael Duez and in this podcast we empower responsible technologists to build a greener digital world, one byte at a time. Twice a month on a Tuesday, our guests from across the globe share insights, tools, and alternative approaches, enabling people within the Tech sector and beyond, to boost Digital Sustainability.And because accessible and transparent information is in the DNA of Green IO, all the references mentioned in this episode, as well as the transcript, will be in the show notes. You can find these notes on your favorite podcast platform, and, of course, on our website greenio.tech. Green SEO, I had never heard the word before last year when I started discussing the topic with Jean-Christophe Chouinard who happened to be one of the thought leaders on this concept. He reminded me something that I actually experienced many many times in my past years as a CTO: folks in charge of S E O often have the final say when it comes to content, design and even sometimes technical choices. And on top of this influence, SEO practices also carry their own environmental footprint being very data hungry. Hence to investigate more this angle, I invited 2 pillars of BrightonSEO, one of the top conferences worldwide on the topic, who are also actively launching a fringe event called the GreenSEO Meet-Up on October 2nd Stuart Davies and Natalie Arney. Both are seasoned practitioners in the SEO industry with a more technical angle for Stuart, who Stu founded the Ethical Agency Creative Bloom in 2014 and is also a passionate surfer. And with a focus more on content for Natalie who has been freelancing for 5 years and is also a singer in the Brighton-based community choir. And I must admit this hit a soft spot for me having spent a wonderful year in Brighton when studying at the University of Sussex in … well shall I say this … in 1998. That's quite a long time ago. Hello, Natalie. Hello Stuart. It's great to have you on the show today.Stuart Davies 02:26Good morning.Natalie Arney 02:27Thanks for having us. Morning.Gael Duez 02:30So, as I said, I think I've never realized the pivotal role that SEO could have in enhancing green IT practices. I just wanted maybe to kickstart our discussion with a very simple question, why should we care about Green SEO at all? And maybe, Stuart, if you could share some ideas on it.Stuart Davies 02:54Okay, thanks. Thanks, Gael. It's great to be here. So, Green SEO, it's two funny words to put together. In 2012, I commissioned some of my team to do some research on to the impact of websites and digital content on the Internet, and I had an itch back then, the vocabulary sustainable net digital sustainability started to permeate a little bit towards me, but it hadn't quite resonated. Obviously, I run an ethical agency. I've always worked with the green and the good and the good local businesses. So it felt that by helping them with their mission, we were helping to do something positive, but we didn't really have a good handle on the impact that we were making. And I think that research to me was a real eye opener. It was a game changer, it was a significant impact. I think there was one stats which really blew my mind. I think at the time there was a study done by a gentleman and he calculated the carbon impact of the Internet to work out that currently he thinks it's a 7th. If it was a country, the Internet was a country, it would be the 7th largest emitter of carbon emissions on the planet and it's on track to be the second of the United States. So it's quite significant what we're doing. So it felt important that SEOs, because we often, I think, as you said, SEOs sit across the divide of digital often. So we sit against digital strategy, we sit against content, we sit against technical, there are many other facets and rings that we actually kind of sit against and we can help influence a much, many factors as well as SEO itself. So it felt like there was a space for a conversation and a space for learnings to be given and a space for open resource tool sets, and here's how to do your jobs. And that's the place that Green SEO is doing. So we're at the beginning of the discovery curve in terms of SEOs and digital sustainability. But that was the point of Green SEO. It started with three of us, initially in Brighton, and those three have grown to 30, of which Natalie Arney is one of our brilliant speakers in our April BrightonSEO meetup. And we're planning to make that 100 next time. That's our plan.Gael Duez 05:24That's a good, healthy, sustainable growth, the one we want. And what about you, Natalie? What brought you to this concept of Green SEO?Natalie Arney 05:35I think I've always been into making the world at a better place in lots of different ways. And obviously, as I've kind of changed my lifestyle to better suit the way that I do things in every part of my life, obviously, work is one of those things that I haven't always been able to control. But now, as a freelancer, I'm able to do that a lot more, from client choices to things like helping them improve the impact of their websites and their marketing activity on the rest of the web, so that we're able to be good examples for other people.Gael Duez 06:23Your clients, Natalie, are they aware of these topics? How do you bring the topic of, hey, I'm an SEO expert and I'd also like to discuss the sustainability angle. How do you kickstart the conversation with them?Natalie Arney 06:39So some of them have already got it on their KPI's and things. So a lot of the brands that I do work with will have targets. So, for example, at the moment, one of my clients actually is being audited to see by a graduate. They're being audited to check every element of their business because what they don't want to do is obviously promote and preach themselves as being a sustainable business and driving all of their activity without doing it in the best way that they can. Some of them, it's part of their brand, as in, we are an e-commerce site that sells things like sells products… It's an interesting one. For example, one of my clients is an e-commerce site, and they dissuade people from buying things.Gael Duez 07:40Wow.Natalie Arney 07:43So, yeah, so obviously it's being able to be a kind of, if you need something, if you really need something, buy it from them and buy the best option. But if you don't, just don't buy it. And it's funny, you know, having worked for agencies in the past where everything's like, “We've got to sell as much as possible and we've got to hit all of these targets.” And it's actually like, well, and I've had a couple of clients that have got this Simmons, like, the same attitude now. It's like, well, actually, we only really want people who really need the product. And rather than driving this kind of high consumption, we all know of Shein and Temu and those kinds of sites, but it's not just them heavy consumers that's obviously then driving waste, driving, overconsumption, driving unsustainable working practices, child labor, so many different things that the impact is beyond the world or beyond the environment is the world rather than just the environment. And, yeah, being able to kind of work with businesses like that is great, but we don't always have the choice to do so. So it's working with people like that when I can, and then when I'm not, it's looking to see, “Okay, what can I do with my brands to help them become better in terms of, you know, accessibility, security, site speed, anything.” And then a lot of the SEO best practices do then feed into, you know, best practices on the sustainability side. But, yeah, it's kind of slowly and surely with some brands and then with others, it's from day one, as soon as you have your kind of call with them, you know exactly what you're going to be doing with them. So it is quite varied. And not everyone has the benefit of being able to say yes or no, whether they're, you know, agency leaders like Stu or freelancers like myself, we both have a lot more control over who we can work with. Whereas if you're an exec and you're just starting out in your career or you're a couple of years in, you don't always have that ability to do that. So obviously taking, getting involved in maybe company projects and things like that, or seeing what you can do internally and attending meetups like GreenSEO can really help as well because you're skilling the team up on understanding and being able to communicate it. Because if you're working with B-Corps, if you're working with businesses that's got all these big goals, you're going to have to be able to work with them anyway and understand and feed it in and it can help get things signed off as well. It's always nice to get an extra thing, an extra ticket signed off just because it's got a green impact, as well as improving keyword rankings, for example.Gael Duez 10:41If we go a little more concrete now, I'd like both of you to explain what are, according to you, the techniques, the SEO techniques that help reduce the environmental footprint of a website, digital services, etcetera. And maybe a bit later we will talk about what is specifically related to SEO. But I mean, we've heard about the size of a website, image management, etcetera, but I'd like you to cover the different angles, not necessarily all of them, but with this extra question, is this aligned or not aligned with what Google expects from us… because eventually they are the big moneymaker here with their ranking.Stuart Davies 11:34As Natalie has touched on, I think that some of the core principles or the big ticket items that you could do for sustainability to make your site cleaner do align with the principles of, say, core web vitals and site speed and performance and up to date relevant content rather than content for content's sake. And these kind of big factors which can impact the website. How much of it is Google? I mean, it's quite interesting. During the last GreenSEO, we did post a post, a tweet, no, an x, as it is now, to all of the search engines asking would they consider applying sustainable digital factors in their ranking algorithms? We're yet to have a response, but we will be reminding them of that question again in October. So if, you know, one of probably the biggest things you could do is find an accredited renewable energy data host. Okay, so somewhere where your, your website is going to be, it's because that's the problem. It's energy use. And if you can, at least the minimum requirement I think, is if you can find, and you can find accredited green energy hosts on the greenfoundation.org website, there's some really good resources on there. You can find yourself a green energy host and you're moving, you know, from potentially a fossil fuel held data center to a potentially green energy accredited data center. I think that's one of the biggest things like the number one impact. Number one things that a lot of organizations can do. Whether or not that doesn't impact, that's not going to impact the front end of the website, the design or kind of the strategy. And this is just where the website is held. Obviously you need to be able to have the same requirements you need for your hosting and the developers will need to get around that. But that feels for me like a good win. If one thing that people would maybe take away from this, that they're not sure where to hit first, that's one of the big ticket items for me.Gael Duez 13:45First things first, make sure you are sustainably hosted. Now once we've got this basic layout, you mentioned that most of the best practices are aligned with the core web vitals. And by core web vitals I guess you refer to the set of best practices that has been pushed by Google as the best way to get good ranking because the information will be easily accessible and as transparent as possible.Stuart Davies 14:16It's also how the website loads, how the website renders, how it responds to people who are coming back, how the images are served, how the layout of the pages moves around with the user or doesn't, how certain features react on desktop and mobile. So all of this is starting to go into the world of design and user experience. The core web vitals does hit into that as well. How fast your website loads, obviously, and what's behind it and how that content actually loads to the users as well. So that's some of the core principles of core web vitals and SEO 101.Gael Duez 14:56And SEO experts will be fully aligned with sustainably or green IT experts on most of these vitals. Could you maybe name the top three top five that are the no-brainer that as an SEO expert, as someone taking care of the SEO ranking of the website because you don't necessarily hire experts all the time in every company. What will be the top three top five things to keep in mind to make sure that you've got both a good ranking and the lowest possible environmental footprint.Stuart Davies 15:35So with core web vitals again, I didn't come up with this word. We use a lot of jargon in our industry and I'm not a techie jargon. Some of the people who work for me and work with me, I call this “make the website quick”. So there, as I know there are three major, three major areas. One is called LCP, Largest Contentful Paint, and that's how quickly the most important content on the page loads. Okay, so you know the banner of the image, however, so you know developers can do things to make that quick. That should occur within 2.5 seconds. That's Google's recommendation for SEO ranking factors. And then that also creates a quickly loaded, presentable website. You then have something called First Input Delay, and that measures how long it takes for a site to respond to a user's first click. Again, these should be very quick metrics and these are some of the things that designers and developers can, can focus on. And then you've got something called CLS, Cumulative Layout Shift. So that measures the page's visual stability as well. So it's about reserving space for images, videos, iframes and optimizing fonts. LCP, Largest Contentful Paint, is all about how to look, how, how you prioritize loading resources, making files smaller, the host resources on the same server and feed. First Input Delay is about reducing the amount of JavaScript and where you can use web workers.Gael Duez 17:21And Natalie maybe more on the content side and the philosophy of searching data, are there any things that you'd like to add on these three biggest topics that Stu just covered?Natalie Arney 17:37So on the content side, I think a lot of it's to do with graphics when we talk about core web vitals, but also JavaScript. So a lot of people will use JavaScript to load menus and add little fun things to navigate content. And alongside that, some people might even just use JavaScript across their whole site. Now that can be really great in some ways. However, the web is still built on HTML and CSS and that's what search engines usually crawl. They have got better at crawling and rendering JavaScript. However, it's not always as efficient as it should be. So usually they go to the HTML first. So making sure that there's fallbacks is really, really important, not just from, from a search engine point of view and a search perspective and having an impact on the core web vitals, but again, like adding in additional layers to that is good for accessibility as well. So it allows people to navigate content, whether they're, no matter what device they're using, wherever they are, they're able to access that content. So rather than having JavaScript disabled on certain browsers, or just not wanting to have things load as fast, and some people will use stripped out browsers, for example, being able to actually access that content is so, so important. And yet not using as much JavaScript or at least having a fallback is super important because yeah, as Stu's mentioned before, not only is that load time having an impact on things like core web vitals, but it frustrates the user as well and then it increases bounce rate and decreases the value of the content and then there's, there's lots of other impact from there onwards.Gael Duez 19:33And so if I kind of gather your point of view, there is one aspect which is basically the size, size, size, size, which is very much aligned with the sustainability angle because the bigger, the more resources, blah, blah, blah, blah, blah. It's a complex story. It's not linear, obviously. Absolutely not linear. But eventually, when we multiply by dozens more times the size of websites since a decade, as brilliantly proven in the Web Almanac Sustainably Chapter, I really encourage anyone to read this chapter because it's kind of mind blowing to see the average size of a web page just exponentially growing over just a decade. So it's really about reducing the size. But Natalie, what you'll see advocating, it's also a technical choice, like not using that much JavaScript. It's not just the question of size, but also some choices that could make this website more difficult to load or reduce user experience. And before I ask the elephant in the room question, I've got a final one which is regarding when everything is well aligned. Did you already see some website size decreasing? Like did you manage to reduce the size of web pages and websites? Or is it still very, very hard to reverse the trend that we are seeing in our industry at the moment?Natalie Arney 21:07Oh, from my point of view. So it's an interesting one because obviously from the content side of things, my talk when I spoke at BrightonSEO in April was all to do with how content audits can really play a massive part, not just on the SEO side, but environmentally as well because obviously there are so many sites and so many brands that are continuing to believe that the more content you have on your site, the better you're going to rank. And we see on a daily basis in the SEO world, people saying how they're going to scale the content on their website. And oh, we've seen these great exponential growth in all of these places and we've driven traffic so, so high now. Like, you know, we've ten x'ed it, we've hundred x'ed it, we've done all of this. And then it's like, well, is that, has that content got any use to the user? What is the environmental impact of that content? How much time and effort has that content made? If you've not got a team creating that content, how are you creating it? Are you using an LLM? And obviously then there's the impact of the use of LLMs from the environmental footprint side of things, but also from the ethical standpoint as well. And then we've also got the fact that you can have loads and loads of pieces of content that are just not getting any traffic or not getting any decent traffic. So although you might be driving a lot of traffic to your website, the pages might have high bounce rates, they might have, you know, really irrelevant keyword rankings, but obviously being able to use and target more detailed keywords, driving prospective customers rather than general browsers, that really is key for a lot of SEOs now. I guess it's a growing trend that people are like, well, we can make charts go up, we know how to do that, but it's going from driving traffic to driving valuable traffic from the commercial side, but also from the environmental side. And there was, I remember reading a case study a while back of a food waste company, and they basically created a new website. And by creating their new website design and kind of narrowing down the user journey and stripping back their content and ignoring those vanity metrics of increasing traffic, they were then able to save over 500 kilos of carbon emissions a year. So I think it was over two and a half thousand miles of air travel a year. Just by just giving their website a little bit of a sort out, running a content audit, really trimming down their design and making sure that it was just really fast, really simple, really impactful. And yeah, the content actually helped people rather than just driving lots of irrelevant traffic.Gael Duez 24:07I'd like to pause here and to share a personal anecdote. When I started my position as a CTO at Solojet, obviously I kind of self audited briefly the website just to understand what was on it. And I ended up discussing with the teams roughly, we've got between five and twelve main pages. Like the pages, like the homepage, the one describing an ad, et cetera, et cetera. But eventually I asked them the question, but how many pages do we have on the website for real? And the answer was more than 1 million and a half. Because for SEO purpose only that amount of pages was and maybe still is created because you basically have one page for every single address in France. Because it is a website based in France. But the same happened in Germany, Israel, Belgium, UK, wherever I worked with a property portal, the same drill and I was shocked like, wow, we are maintaining more than 1 million and a half page. What is the traffic on it? What is the use? I mean, we could get rid of it. Are you really sure? And the answer was always yes. But think about the long tail. It doesn't cost that much. And whenever someone will hit, you know, mostly what is the price for a property in this specific street, in this specific town, etcetera. We want our websites to be ranked super high if possible, number one. So we need to think about the long tail and we need to maintain then 1 million and a half in a highly automated way. And we were not even using LLM back in those days. So this is my personal feedback from a very wasteful behavior. But still, business wise, it makes sense. What would be both of you, your point of view on this? Do you really believe, or is it really the case that the long tail works that well and requires that amount of resources? Or is it a misconception or is it a way between, I would say.Stuart Davies 26:16I mean, with long tail content, I have an agreement with most of my clients, but my clients are the green and the good. These are people who are early adopters. The challenge is bringing some of these principles to the mass market. But we've got an agreement where we've got a one in, one out on the website. So it's okay, we'll put in, we'll put in a piece of content, but we're going to take some of it off. And that's how we manage our long tail content strategies. So yes, there is a place for it, because often you are answering useful information, a question that someone wants to ask about your product or service, that it is useful to have or to provide that on your website, but it can go so crazy. And what we found was it kept the size of the website lean and lo and behold, it also kept their content strategy lean and really did their rankings quite well. So that's how we've approached that particular thorny subject.Natalie Arney 27:13So I keep going back to it, but my bright and SEO talk, so basically the name of my talk was “Reduce, reuse, recycle your way to content success.” And basically what that involves is obviously content audits. And I really believe in having really impactful, useful content audits on a regular basis, I would say at least every year. And from that side of things, you always need to keep a grasp on which pieces of content are driving traffic and which are getting good engagements. Like I said, with a case study, having that impactful content that drives conversions, that drives kind of meaningful traffic, rather than just making the graph go up, is so, so important. I think looking at what you can consolidate and what you can improve in terms of content is so important. You might have some really useful content from years ago that just needs a refresh. That could drive a lot more traffic through better keyword rankings. It could be that you have got some outdated information, for example, on an article, and you can just go in and tweak it rather than creating a whole new article. Or it might be that you go back and you've been working on a client for a couple of years and you find some content from about five to ten years ago that could be relevant to you now. And instead of creating a whole brand new article in your content calendar, you could consolidate all of that content together and get rid of additional pages and put everything in one new piece of content. And it's making sure that your content strategy isn't just creating more content and targeting the long tail, it's being able to do it in an effective way. And that's not just from an environmental point of view, but also from an SEO point of view. Years ago, people would create pages upon pages to answer every single query. And obviously, because Google's semantic, it groups content together. Well, in theory, it groups content together by theme and by topic anyway, so you might have pieces of content that might not mention a keyword or a theme, but are related to that keyword or a theme, then ranking for those related terms. And it's like, well, they might be ranking low, but Google and Bing can see that you're trying to kind of target that. It's almost giving you hints when you look at it and go, oh, well, actually, I could work that into that article. And it's looking at that content and saying, well, actually, what have we got now? What do we need? And can we fulfill what we need with what we've already got? And then moving on to creating that new content. So you might have articles, you might have landing pages, and see what you can consolidate, what you can improve before then going on and making brand new content. If it's more kind of on an evergreen side, if it's more trend led, then obviously it's creating that content there and then being able to do that. But where you specifically got really kind of evergreen content, it is so, so important to have your regular content audits, content refreshes and it can work. I had a client last year and it's one piece of content. It was getting less than 300 visits a month and we basically went through, gave some recommendations. It was a couple of paragraphs worth of text that needed to be added and a few headings that needed to be moved around. Within six months, that content was getting over 3000 visits a month. Just for that one piece of content. It was the top piece of content on the site. So it's really, really important to refresh that content because you never know what you might be missing out on and obviously who you're missing out on as well, without then having to create lots and lots of new content, which then has the impact on the hosting, this page, speed and everything else.Gael Duez 31:06And if I'm following you there, what I hear is two main messages, which are first of all, chase the right metrics, get rid of vanity metrics. After all, even if you're an e-commerce website, you don't want people to spend 1 hour on your website, you want them to spend 10 seconds and then, you know, live their life after having buy your items, obviously. And the second one is the issue is more about stewardship, about caring about your content, recycling your content than just adding new one.Stuart Davies 31:40There's another issue here as well, Gael, and this might segue us nicely into SEO specific green SEO strategies and tactics. This applies certainly for bigger websites, those with thousands, tens of thousands, some have hundreds of thousands, some have millions of pages and it's managing the bots or managing the crawlers. So out there you've got lots of web crawlers, you've got Google, you've got Bing, you've got so many different kinds of SEO tools. You've got ChatGPT coming into websites now and all of the various permutations of AI tools coming in, there's a lot of malicious stuff coming in the spam. There's a huge amount of now that creates resources as well, that creates resource drain and energy use as well every time a crawler comes into your website. And what SEOs can do specifically is they can use the robots txt file. So it's a file where we can instruct website crawlers what to do and what part of the website to look at. So, you know, if we think at scale, we've got a huge, huge, massive website with lots of archive material. I know Will Barnes from Reed Pop. He works for a gaming company. So they have lots and lots and lots and lots of archive website material which they want to keep but not rank. So they will use their robots txt file to say, this is just our archive. We might pull out some of them. But I don't want you to come in and crawl this anymore because you're, you know, I want you to focus on the bit of the site I want you to do. Or you could have lots of FAQs sections on your site which are just for readers. It's not useful for search because you might just have one FAQ page. You can also block the search engine from using that. So on a one page basis it might not feel like much. But when you start adding this stuff at scale, it does become important and it creates less load on the servers. We can also block AI, ChatGPT. It's yet to be quantified. What the impact of that is on website loads, but I imagine it is quite significant. But what we're doing at GreenSEO is we are going to produce a file SEOs and digital marketers can use to put on their robots txt files. That's the file that controls the search engine which blocks all of the bad bots. So it's saying these are definitely ones which will come into your website that you do not want anywhere near it. And then again, sir, that's going to be open source on the greenseo.org website. And that's really going to help with the server load and the resource use on websites as well.Gael Duez 34:30Yeah, because obviously it drains resources. It creates data which has to be stored and analyzed sometimes, et cetera, et cetera. But it also drains resources from the owner of the website because they need to enter these bots. Okay, got it.Stuart Davies 34:45So it's like we're all littering and someone's coming up to your property and leaving their litter and you didn't ask them to.Gael Duez 34:53I think it's a great example and I love the idea of creating some sort of open source community where everyone will share. Okay, bad bots file, like the Dark Web Foundation repository, like you've got the Green Web Foundation, like not dark web, maybe gray Web, whatever. Yeah, that's definitely a great idea. And something that I didn't consider because I was more considering the robot text.Stuart Davies 35:22The robots that text.Gael Duez 35:23Yeah. As you know, something that you don't want data to be produced when it's not needed. But actually, yes, obviously it can drain a lot of resources from your own hosting solutions.Stuart Davies 35:37It's a good place to start, especially for big websites, websites at scale, e-commerce websites, anyone with a huge footprint, again, that can really help.Gael Duez 35:46And as an SEO expert, or not expert necessarily, but an SEO practitioner, do I have things to change specifically in the way I work or new tools to embrace to help me with having a more sustainable way of working?Stuart Davies 36:02So the GreenSEO website, greenseo.org, is a repository and a toolset and it has the playbooks of here are the things that can help you do your job, here are the tools that you can use to address speed, page weight design, here are the other people who are talking about it, such as sustainable design resources, such as pointing to whole grain, digital, Green Web Foundation and a sustainable web, all of those resources as well. And we've also put on there from our learnings some of the playbooks in terms of how you can go about introducing a sustainable web into a large organization that doesn't necessarily have it at the core of its values. And we expect that to grow. It's going to be open source and it's for anyone who's got a story, anyone who's done something to contribute to this. The whole thing about it is just getting it out and saying, “Here you go, here are tools to do your job and here are some of the learnings and here's what we've done and here's what's worked.” So that's a good place to start.Natalie Arney 37:05So one of the things that most SEOs have got in our toolkits is a crawler. And the two main crawlers that I use are Screaming Frog and Sitebulb. And one of the things that Stu's managed to and the GreenSEO team have managed to arrange with Screaming Frog is that in the Screaming Frog crawlers now you can get the carbon impact of certain pages and elements in the auditing tool, which is fantastic. So when you are auditing a site and if you want to add in as part of your website auditing process or a separate process altogether, it might be, say, feeding into a consultant like one of my clients has got at the moment where they're auditing everything on the site and not everything to do with the business is, yeah, you can use that and that's fantastic. And thank you to Screaming Frog for doing that because it's going to help a lot of us do our job a little bit more effectively. And then obviously when you're using your crawlers, you can switch them into dark mode as well, which is always handy too. So yeah, always switch your crawlers into dark mode.Gael Duez 38:13I reckoned integrated the CO2 GS library to calculate the website carbon. Am I right or is it something to check?Stuart Davies 38:23Yes, I believe that is correct. Yes.Gael Duez 38:27And actually, Natalie, you touched upon something interesting as well, which is the amount of data that is produced by each SEO practitioner. That sounds to be quite significant. When you crawl and crawl and crawl over, is there anything also that you, or Stu, you want to tell us in terms of best practices and how to reduce our own environmental footprint?Natalie Arney 38:54Go on, Stu, I think you're fair.Stuart Davies 38:57Okay. Right. So I'll go first. So yes, SEOs and digital marketers use a lot of analytics tools and we use a lot of software for SEO for conversion rate optimization, for UX, for example. Heat mapping is a very good example. So they'll get used on 1% of the website, on a project that might run over one month and they'll put scripts and recordings onto the website. And then generally tools like that are then left to run. Also all of the various kinds of plugins that are active on browsers. And so things like this, again, it's our own kind of personal imprint as well. So what digital marketers and SEOs can do is make sure that if they're using any analytics tools and crawlers as well, like setting regular crawls and all of those things is take the scripts off of the website once they've been used or make sure that you're not littering. Make sure you're only using things and switching things on when you need to use them. I think there's like so many software tools that go into people's websites and crawling because someone set off a project on a website crawler at some point and it's just sitting there doing it, it's not being used and it's just taking data and things like that. So we personally can do that. So I'd say that someone would want to check what's running on their website and also personally, what have you got running in the background on your own machine that's on all the time or not on all the time, and think very carefully about, you know, what tools you use and also maybe check out the credentials of the tools that you're using. You know, you could run their website through a carbon metric and see how that stacks up. Or you could even better write to them and ask them and introduce the conversation to them. So there's definitely things that we can do individually.Gael Duez 40:51Yeah, I think Holly Cummins that coined the word cloud zombie, you know, in the DevOps words that you kick start an instance or a server, et cetera, and you don't pay attention because it costs not that much money because the load is so low, et cetera. So maybe in the SEO world there is something like crawl zombies or optimizing tool zombies that we should pay attention to. But that's so true. I mean, I've audited websites and some pages where I had countless ads on that were not used anymore. And a bit of JavaScript here and a bit of JavaScript there and oh, it used to be for this media campaign that we ran like one year ago. I was like, what the hell? We don't need that anymore. But we tend to forget. Yeah, that's absolutely true. So we covered a lot of techniques and how to make SEO practices greener. Maybe one of you could share a practical example. I mean, do you have a client, even if you cannot name it, who actively embraced a GreenSEO approach and where you could share what worked well, what didn't work that well, what are the main pain points? Like if someone wants to kickstart a conversation in his or her company or clients, what should be the best first steps based on these use cases that one of you could share?Stuart Davies 42:28I'm happy to share one. I can't name the company. What I can do is say that one of the Co-Founders of GreenSEO is involved with this company and it is an extremely large international global tech firm with an extremely large footprint and extremely complex change management IT barriers, getting things done. So this was very example, so this is an example of a super huge company, super huge corporation, and then somebody trying to introduce some of the principles of GreenSEO digital web and what we call this is planting seeds, I think, and this is the right lot, people can take this away is this is a big subject, but what you can do is plant a seed and watch it grow. And so what the person did is he decided to go after dark mode. Okay, so wanted to do something. Dark mode reduces the energy use of the person, browsing the screen on the load, et cetera, et cetera. And so you wanted to introduce dark mode on the sustainability section of the website. Okay, got there. So what he had to do initially was get buy-in. So he went and tapped on the shoulder of the sustainability person and he also got user polls. He did user polls internal and external to get some stats behind the change as well. So he was starting to push out. But what is really important is you've got to contextualize the argument. So what this person did was measure the carbon weight of the pages and then say, measure it what it would be like in dark mode and say, well, this could be the impact. And wouldn't this be great as part of our CSR reporting that we've actually done something to actually clean our own pages? Okay. So the sustainability team got really interested. Okay. He then actually, then spoke to some of the developers, got buy-in from his management. He had to do a presentation, internal presentation. He had to get find some friends and they all went for it. And so he had the development team in there, he had the change team, the branding team. Everybody loved it. That was kind of the key learning here. Everybody loved it and nobody put in a barrier of obstacles. The only thing they asked for is that the dark mode would be a toggle that users could switch on and off just to satisfy any kind of jittery stuff. And then the DevOps team just put it through. They just went, oh yeah, we've just put it, we've just done it. So they didn't have to go through the big change stack as well. So this was like immediately there was one page and then suddenly a week or so later, the sustainability team from one of the other countries got in touch saying, what have you done there? Can we get that as well? And then suddenly other sections from the website, because it's quite siloed, start getting in touch saying, what have you done there? Can we do this? And then as a result of that, one of the sub-sites of this massive technology firm, which has a footprint of say, 100,000 pages, it's going to do the entire subdomain on dark mode toggle. So that's, that's how and that's extremely impactful. So that's going to save a huge amount of carbon. I haven't quantified it, but that just shows you how you plant one seed and you can start small, can suddenly grow off and take mode and, you know, it's what we call marginal gains. You know, there is a marginal gains strategy to SEO and there is a lot of… can't talk about it, but also marginal gains to sustainability because it is such a big subject and it can be quite scary for large organizations to do something which is going to impact their strategies. But these kinds of small seeds that can be planted seem to sprout. So I think that was a really good, really good case.Gael Duez 46:12At least on my island, you can see quite often that a plant will break a rock after just a few years. So at the pore of seed, definitely. Maybe, Natalie, from your perspective, going the absolute opposite direction with a very small company, if you had to advertise like a small or medium sized company running a basic website, maybe a small e-commerce activity, or, I don't know, a small media activity like greenio.tech, which is not optimized for SEO as well. I know I need to pay attention to it, but I didn't have time. So anyway, what will be the main steps? Knowing that it's less a question of seeds that I guess budget and having the time to start something?Natalie Arney 47:04Yeah, I think as you mentioned earlier, I think it's really important to think about your hosting, first of all, because it has so much of an impact. Obviously, my talk at GreenSEO is about greenwashing and there are hosts that do greenwash. So it's really, really important not just for the environment, but also for your brand reputation, is to work with partners that don't greenwash and that actually, you know, that work really well. And there are some really great companies out there that do some great, great things on top of having a greener hosting and legitimately greener hosting. So I would say start there. Always think about from an SEO point of view, but also from a sustainability point of view, think about the value and the use of the content that you're creating. Really, really important. And do you always need that extra bit of JavaScript or is it just to make the user or the client and not even impress the user? Is it there to impress your boss or the client, or is it there to be actually helpful for the user? Because obviously at the end of the day, everything that we're doing is for the user, whether that's to make their web experience better or to make sure that their children and grandchildren have got a nice place to live in a few years time. So it's kind of encompassing all of that together, I would say, yeah, if you've got a small website, think about the hosting, double check kind of sense check what you're doing to the site. And yeah, see if you can get, if you're say, on WordPress, it's pretty easy to get your core web vitals scores as close to 100% as possible. Obviously using different technologies is a little more difficult, especially out of the box. And obviously a lot of SMEs use things out of the box like Wix and Squarespace and things like that. But yeah, and then I think, yeah, I think about hosting, think about platform, think about content, think about load speed, and they're there. The fundamentals, not just from the environmental point of view, but it's SEO best practices as well.Gael Duez 49:20And maybe before we close the session, is there a situation where what Google expects from us is not aligned with a more sustainable approach?Natalie Arney 49:36I guess it depends on what your position is about SEO tactics, because there's a lot of different types of people in the SEO world. There are people who will flood the Internet with garbage and obviously that floods the environment with garbage and they don't care about that. And then there are people who care about good quality content that actually serves the user's needs. And without going into too much detail and discussion about Google and the changes that have happened in the last few years in particular, at the end of the day, Google wants to be able to serve the best results for the user and to keep people on their platform as much as possible. So it's thinking about what is going to be useful for you and your users, because depending on what happens with all kinds of monopoly, breakups and business related corporation things to do with the search engines and to do with potential competition on the horizon from other companies that may or may not be just doing it to inflate their stock prices and investments, it's really, really important to think that obviously we don't just get traffic from search or we don't just get traffic from Google. People are moving away slightly, maybe using alternatives for lots of different reasons. But yeah, I think it depends on what… I hate being as SEO and saying it depends, but it does depend on what kind of SEO you are, whether you're one that kind of cares and does kind of as best practice as possible, whether that's against Google's conditions or not. It's what impacts you and your site and your users, or whether you just don't care and you're just going to continue to flood the Internet. We've got absolute, and I mean garbage. There are other terms that I did use in my brain, SEO talk about that. And you know, Ed Zitron and Co will talk about that a lot more in their kind of publications and podcasts about the changes that have been made, particularly at Google. But I think, yes, it's important to kind of consider what kind of SEOs people are first and then go from there.Gael Duez 52:07Got it about the garbage. I think we've all experienced this kind of website or content.Stuart Davies 52:13I mean, I thoroughly believe that the principles of GreenSEO are aligned to good SEO. So there's nothing in there at all that I would see that is going to impact your rankings. It might upset some brand designers when it's kind of, you're starting to sort of move into the design things when you talk about fonts and images and videos and sort of things like this. But there's nothing I have seen so far in terms of tactics for GreenSEO or green web that I think would significantly impact rankings. In fact, I think it really complements it in most cases.Gael Duez 52:53Okay, so not such a hard sell to do with clients or executives.Stuart Davies 53:00The hard sell is around behavior. It's ingrained behavior. It's ingrained behavior that this is how our website needs to look. It's ingrained behavior that this is how the marketing team creates content and churns it out. It's those ingrained behaviors like, oh, this is how we know this weird digital environment works. You know, we have our big glossy websites with lots of resources on and we know that works. And we know if we produce lots of content, we know that worked. And what we're saying is we're starting to see case studies where that's not the case, but it's those behaviors and that's the cell and because the data is still coming out, which is why it's very important to contextualize the debate and maybe to start small. So we go actually, well, we're going to tackle one section of the website. Let me try this one section of the website and we'll see what happens with it. So that's how I think people can start to make inroads into that ingrained behavior.Gael Duez 53:58Okay, thanks a lot, both of you. Before we close the podcast, you mentioned it several times, but do you want to pitch one last time the GreenSEO Meetup in Brighton? Why should people attend and what kind of people should attend?Stuart Davies 54:20Well, you should attend because it's hosted by us and we're really lovely people. And it's a community starting to come together of digital marketers and SEOs who care about the environment and have either a story to tell or have done something or have found some way to help clean up the environment or help them do their job. And it's part of BrightonSEO, which is one of the world's biggest search marketing conferences, I think. And they're really, really great and they've given us the platform as part of their conference to be able to have this fringe side event really focused on sustainability. We've got Screaming Frog as our sponsor. They are demonstrable impact in helping SEOs do their job to be able to do carbon audits. And we've got three great speakers lined up as well, which Nat was one of ours in the last time. It's free. There's going to be drinks, soft and other types of drinks as well. Just 2 hours. So if anyone is in Brighton and you're there as part of the BrightonSEO conference, just pop in the GreenSEO BrightonSEO event and you can just sign up for a ticket and come straight along. It's just a couple of hours and we will most probably go to a pub afterwards. There we go. Sold it.Stuart Davies 55:46We like a good pub called Gael.Stuart Davies 55:57Now we're going to the pub.Stuart Davies 56:03I know, I know, I know.Gael Duez 56:14Okay, great. It was really great to have both of you on the podcast. Best wishes for GreenSEO Brighton and hope to see you maybe in Green IO London as well. Thanks again for joining.

#45 - Assessing digital sustainability’s maturity with Aiste Rugeviciute and Rob Price

In the early 2020s, companies started facing a big question: how could they be more responsible in the digital world? Could something similar to CSR exist for this virtual and yet highly materialized world? Corporate Digital Responsibility (CDR) was coined to offer some much-needed guidance.🎙️ To explore its ramification, Gaël DUEZ chats with two renowned experts in CDR: Aiste Rugeviciute, co-author of “B.A.-BA du Numérique Responsable” and now pursuing a PhD in the socio-ecological impacts of CDR strategies, and Rob Price, a key player in developing an international CDR framework. Rob also hosts the “A New Responsibility” podcast, diving deep into CDR's role in business.Some Takeaways:    🔑 the CDR framework in a nutshell,   🌿 the importance of embracing a balanced approach to CDR in most companies, and   🛠️ a sneak peek to the newly-released CDR maturity model.❤️ Subscribe, follow, like, ... stay connected the way you want to never miss our episode, every two Tuesday!📧 Once a month, you get carefully curated news on digital sustainability packed with exclusive Green IO contents, subscribe to the Green IO newsletter here.  📣 Green IO Paris is on December 4th and 5th 2024 --> use the voucher GREENIOVIP to get a free ticket! Learn more about our guest and connect: Aiste's LinkedInRob’s LinkedInGreen IO website Gaël's website 📧 You can also send us an email at contact@greenio.com to share your feedback and suggest future guests or topics.   Aiste and Rob's sources and other references mentioned in this episode:CDR ManifestoB.A.-BA du Numérique ResponsableA New ResponsibilityMaturity ModelEthos FoundationGlobal action plan for a sustainable planet in the digital ageTranscriptIntro 00:00To change, we have to think about how organizations or governments incentivize change in an economy and how that helps businesses to do the things that need to be done better.Gael Duez 00:25Hello everyone, welcome to Green IO with Gael Duez - that’s me! In this podcast we empower responsible technologists to build a greener digital world, one byte at a time. Twice a month on a Tuesday, our guests from across the globe share insights, tools, and alternative approaches, enabling people within the Tech sector and beyond, to boost Digital Sustainability.One of my more esteemed peers in Digital Sustainability, and a good friend, who’s now CSO of a large digital tech company used to work before in the garment industry. Sometimes, well quite often, she goes ballistic about the infant level of the digital industry in sustainability compared to other industries. The very idea that digital technology produces products as does the garment industry with clothes and that these products have a footprint both environmental and societal is not that widespread. And when Tech executives become aware of it they often lack the frameworks, the best practices and the metrics to steer the sustainability angle of their company. And answer this pivotal question in an industry, which has just a touch of ego and hubris: how good am I compared with others? And eventually, how good am I with keeping our planet habitable for the human race. Am I being too sarcastic here? Well let’s go back to a more action-drive mindset then. Since the beginning of the 20’s, a concept has started to emerge embracing these questions and providing some framework for companies with a significant use of digital technology: the idea of their CDR. Full disclosure, I am using this approach with clients when I do consulting gigs so I might be a bit biased. As usual, question and double check everything that is said in this episode. All the references will be put in the show notes on greenio.tech and on your favorite podcast platform. Transparency and Accessibility remain in the DNA of the Green IO podcast. To deep dive in CDR, I have the pleasure to welcome 2 of the best experts we can find on the topic. Aiste Rugeviciute who graduated in both computer sciences and Sustainable Development and Social Business and has worked for several years on the intersection of Tech and sustainability, she co-wrote the hands-on book "B.A.-BA du Numérique Responsable" in French and she is now doing a PhD on Corporate Digital Responsibility (CDR) strategies and their socio-ecological impacts. Rob Price is one of the core members of the international group of academics, corporate practitioners and published authors who collaborated in 2021 to aggregate their existing body of work into a single, international definition of the set of principles supporting Corporate Digital Responsibility. He’s also a fellow podcaster with the “A new responsibility” podcast which covered during 5 seasons the use of CDR in companies. He gave a much listened talk to Green IO London last year. And btw this year Aiste will be the one giving a talk on her CDR Maturity Matrix. So make sure to get your tickets for this great gathering of responsible technologists on September 19th. And without further notice, Welcome Aiste and Rob. Thanks a lot for joining Green IO today.Rob Price 03:55Thank you.Aiste Rugeviciute 03:56Hi, thanks for having us.Gael Duez 03:59You're more than welcome, both of you. I have a terribly complicated question to start. Could you define CDR in two sentences maximum?Aiste Rugeviciute 04:12Well, it is a complicated question because there is actually no one definition, at least between the academics. Everybody comes up with their own definitions. But in a nutshell, I would say there are two main ideas. So the first idea is, of course, about responsibility. So what are companies' responsibilities with respect to digitalization, or the way they use digitalization? And the second one is trying to maximize the positive effects of digitalization while reducing the negative ones. So that's kind of the two main ideas combined. Rob, what do you think?Rob Price 04:57Well, I mean, it goes back to the introduction, really, doesn't it? So in 2021, that was the question we asked ourselves, and we wanted one sentence that described CDR in the context of all the definitions that the variety of us had created at the time. So, I mean, reading that corporate digital responsibility is a set of practices and behaviors that help an organization use data and digital technologies in ways that are perceived as socially, economically, and environmentally responsible. I think the key thing for us was, at the time, trying to think of something that provided a framework and guidance to help organizations be aware of the consequential impact of the things that they were doing. And no doubt, through the conversation, we'll talk more about finding the right balance in terms of framework versus measurement criteria versus a method, if you like, in terms of organizations doing those things.Aiste Rugeviciute 05:57I think also one of the key things, what Rob just said, it's about the perceived value. What's in line with the so-called reference points in the society. That's kind of a key thing when corporations, organizations think in general about their responsibilities, and when it comes to digitalization, aligning with societal social expectations and all the idea, you know, if it's contributing to reducing climate change or any other negative impact, it's all about in line with what right? In line with what expectations and whose expectations. That's where the question of responsibility comes in place.Rob Price 06:48And can I build on that very briefly, which is, I'm very conscious of talking about CDR in multiple countries around the world. I think it's very difficult to be really tightly defined, because you have to be conscious that different countries, different political systems, different cultures, there would be pushback if you kind of introduced CDR as a mechanism that you had to follow. Literally. It's important to be conscious of the environment in which you're asking organizations and governments to think about the way in which they operate. Even if they take some of those aspects, that's better than all of those or none of those.Gael Duez 07:31So it's really a question of contextualizing the approach, and still we reach some kind of agreement around the world and I guess some principles, some guidelines, as both of you mentioned. Could you maybe elaborate what are the main guidelines, the main items that have reached some sort of consensus that, yes, we should pay attention to this aspect and this aspect and this aspect.Rob Price 08:02So, in a sense, the blank sheet of paper that we did start with in the past was probably between about 2016 and 2020. A number of definitions of CDR did appear. Some of those were written from business points of view, or government points of view, or academic points of view. But when we did an analysis of them, I would say that 80% of them were pretty similar. Maybe some were focused more around sustainability, some were more focused around trust and inclusion, but 80% was common. And the purpose of the work that we did at that time, with all of those parties bringing together those definitions, was to try and find a common framework that actually was inclusive of everything. So we defined a framework of three intersecting circles, which gave us seven principles. If you think of each of those sections, at the heart of everything was trust and purpose was beginning to be talked about more commonly. So, purpose and trust, fair and equitable access for all. So that's around equity, diversity, inclusion, and more societal well being. Thinking about the impact on people, one of the things that I almost enjoy is when I'm talking to organizations asking if their products and services are predicated on addiction to drive advertising rates, it's always an uncomfortable question. But nonetheless, thinking about the impact on people, considering some of the economic impact, I think is interesting. The fourth principle, economic and societal impact, and probably one of the hard ones. But it's beginning to think about some of the things around algorithms, fair share of outcomes, of benefits, the way in which you value things that you're delivering through digital technologies. Talk about the impact economy in principle five. So, thinking around, or beginning to think about that intersection with the economic and the sustainable side of things, and goes into more detail about supply chain and green tech, and some of the ways in which you can use digital services to directly impact, innovate around sustainability. And the final two, very much focused around sustainability. I'll start with seven. Seven, reducing the tech impact on the climate. You're thinking about what is happening with my data centers. Am I using renewable energy? Is it really renewable energy? Etcetera? And then six, we talked very briefly at the start around innovation, thinking about how I can use these technologies to innovate and solve the world's biggest problems, especially around sustainability. So I think this is a really important one. I want to explore it later. We talk a lot around impact of AI, for example, which clearly has massive energy use, massive water use, in terms of data centers. That's something to measure principle seven. But it's really important to think about principle six in terms of how I can use that technology to create positive impact and benefit on those very things that I'm worried about negatively impacting. And it's a balanced scale. So those are the seven principles. They go into far more detail through the manifesto. There have been other definitions that have emerged since, but I can track them all back to those seven principles. I haven't yet seen something appear that's new, a new concept that doesn't fit into that framework. And of course, we do continue to look at those definitions to determine how we continue to evolve, because I don't think any of us said when we created this back in 21, right. That's it. We've cracked it. Nobody could ever improve on that. It's always evolving, always a living thing, and then it's how people bring that to life, which is probably a perfect position to hand over to Aiste, in terms of the work that you've been doing.Aiste Rugeviciute 12:05Yeah. If I might just add or more generalize. So those seven principles, they are a little bit in more detail, but if we take a step back, basically, we can summarize that it's about the environmental and social side. So we have both sides, and that's what Rob was talking about. Right. So there are social, societal questions and there are environmental questions at the same place. Why I'm underlying it, because sometimes especially, I don't know why, especially in Germany, when they used to speak about corporate digital responsibilities, they completely ignored, or they tend to ignore the environmental side. So they tend to look only on the social, societal side and especially concentrate on the data questions. Now, it's shifting a little bit, but at the beginning, I remember when I was reading it, I was surprised to find it because it was completely the other way around. In France, everybody, whenever they were talking, they were talking only about environmental questions. And the social societal questions were put aside and that was being dealt with by more, way more engaged people or very niche, niche people in certain NGOs. Currently, I can see that the discourse is becoming more balanced, which is nice. So it takes into account two sides. So as I said, the environmental and social, societal side. But it's also the question of technologies perceived as a solution or as a problem. So that's we have both technology or digitalization. So we have to generalize two dimensions. So there is one environmental, social, societal side, and then is it good or bad, or again, it should be balanced discourse, but that's the attitude as well.Gael Duez 14:09And I have one small question just to clarify. The principle number seven, which is the impact on. Rob, you mentioned impact on climate. Is it only climate or is it all kind of environmental footprint?Rob Price 14:25Yeah, no, it's reduced tech. Impact on climate and the environment is the actual words that it says. So it is that consequential impact on everything that you have directly or in the supply chain, on the climate and the environment, planet, etcetera. And I think I wanted to just add something to the thing, the description ack, because it is absolutely about people, communities, society, planet in its entirety. I don't want to forget what I think is probably the hardest part of it to think about sometimes, which is the economic kind of angle, if it changes. We have to think about how organizations or governments incentivize change in an economy, in their geography, in their region of responsibility, if you like, and how that helps businesses to do the things that need to be done better, whether through incentive or whether through regulation. So it's that intersection of all aspects of that. I think it's complex. It's not easy. I mean, we've seen that over the past few years. Many organizations that I speak to, they're not trying to solve everything. At the same time, that's not realistic. It's about understanding the consequence of the things they're doing and honing in on some things that would make a difference, that are important because it positively impacts what they're doing or the way in which they're seen in the market, the respect they're given, if you like, the ability to better place product or service because of those things that they're doing. So it is a finely tuned thing engine that you need to kind of understand how we can nudge it in the right direction to be better in terms of the impact it has on the environment and everything around that. If we were talking seven for example.Gael Duez 16:26And now that we kind of lay the ground with the main concepts and the subtle equilibrium between them in the intersection and the kind of systemic interaction that we can see between the seven of them. If I'm listening to this episode, and I'm convinced that, ooh, this framework sounds very interesting, how do I go from the academic and conceptual approach that helps me to better understand what I should pay attention to, to something a bit more concrete for me or actionable for me? And my main question actually will be, Aiste, do you believe that the CDF principles can become actionable?Aiste Rugeviciute 17:12I would very much hope so.Aiste Rugeviciute 17:17There are different steps before they become concretely actionable. Right. So the first question is, I think to ask, why do you want to do that? And then to ask, what do you want to do? So why? I think it's an important question, which, especially in the organization corporation environment, sometimes it's forgotten by the practitioners and then they are being asked by their managers, you know, and they're like, yeah, but why? What's the purpose? Right. So the question why is very important because most of the time the response is money, is to make profit, to respond to the stakeholders. Right, sorry, shareholders actually. But beyond that, we have other requirements. And that's where I come back to the same notion of responsibility. So the why could be because there are legal requirements, there are risks associated, there are opportunities, there are myriad of stakeholders who suddenly have shifted expectations. So your direct clients, it might be your B2B clients, right? It might be the societal legitimacy for you to stay active in a region, in a state, in a country. It might be simple because you want to benchmark yourself with others, so there are reputational damages, et cetera, et cetera. So the first question is, actually why do you want to do that? Is it because you want to go back to reduce risks, take some opportunity, go beyond your legal requirements and so on. Once you kind of clarify the idea why you want to engage in the CDR, it's going to be way easier going forward to structure your actions and approach towards these guidelines. So let's imagine that you are B Corp, for example, and your idea that you want to do CDR because you want actually to contribute to creating a better society. And you consider that yourself as an organization corporation. That's one of your responsibilities.Gael Duez 19:55By B Corp, you mean the label that some companies get.Aiste Rugeviciute 20:00Yeah, sorry, I put the label because I know that in the US, when you get a B Corp label, it's much easier to act in line with societal expectations, and not only with your shareholders, because in the US there's a lot of shareholder pressure to get profits, monetary profits. But once you have a B Corp label, they change status in their corporation, legal, something with legal things that in that case, corporations are expected or are allowed way more freedom in order to act in accordance with societal expectations.Gael Duez 20:48Thanks for the clarification. And let's go back to what you were saying previously.Aiste Rugeviciute 20:55Yes. So once the company decides why they want to do that, the next stage is to understand where they are now, right? So maybe you are already doing very well and your corporate digital responsibilities. So once you clarify your responsibilities, the question is, okay, what is our current state? And once we evaluate the current state, once we reflect on what we are doing now, then we can look at how we can improve ourselves, where we can go in order to go to our objectives as well. A question is, objectives, is it a continuous objective? Is it very concrete that you want to, I don't know, reduce your CO2 consumption by your information systems, or you want to reduce the digital divide in the society? So digital divide in the society, you know, you can have very concrete milestones, but it's a continuous action, right? It's not going to be at some point completely achieved over. So that's basically the three steps. So the first question is why you want to do it. Second one is analysis, understanding where you are now. And the third one is putting the milestones, objectives, priorities. Because as Rob mentioned, you can't do everything at the same time, especially as an organization, you have so many things on your plate. So, you know, you have those seven principles which Rob mentioned, but between the seven principles, maybe some of them have higher priority because of where you work, because of your industry, because of your stakeholders, because of the whole context.Rob Price 22:42Completely agree with that. And just, it's a really important point, I don't think, when everyone who fed into that work was never saying there was an equal balance, or needed to be equal investment to address and mitigate each of those separate principles. It's a framework, and the framework is then applied to the organization. I think very few times has an organization ever come to me and said, we've decided we want to implement CDR, how do we do that? Most times it will be they're worried about reputational damage, or they know that they need to improve something around their impact on the environment, or how do they get trust, because they're worried about reputational damage. So it's more around applying it as a framework to help that organization resolve the concern. Or maybe there's been an incident that's highlighted a problem that is perceived across that organization, and it's how they begin to find a pathway to make an improvement that improves the thing that they're concerned about.Aiste Rugeviciute 23:52Always some kind of entry point towards that CDR, as Rob said. So it might be reputational, it might be very often a regulation, currently at least what we observe in France. So you have regulations which ask you to reduce your electricity consumption, energy consumption, and reduce your CO2. So that's an entry point. So companies say, oh, I need to reduce my CO2 somehow. So let's try to find all possible leverages. And then when they start looking and they say, okay, well, I might reduce my CO2, for example, or environmental footprint by reducing the number of screens we have per collaborator. So my overall footprint, environmental footprint is going to go reduced, but then that's going to affect productivity levels of my collaborators. So wait a second, that's kind of related to something else, right? And then it might still mean, oh, it's very complicated, the digitalization as a problem itself, it's a systematic problem, and there are different impacts which are very much linked with each other and they're not necessarily going in the same direction. If you reduce one, it can be at the cost of the other. And I think that's where the structured approach of CDR, reflecting on it, allows organizations to take into consideration more things which are more important to them and their stakeholders and the challenges they are trying to respond to.Gael Duez 25:29Rob Aiste just shared a very concrete example on this kind of trade off and multidimensional approach. Could you share an example of a client? You can name it or not. You might be under an NDA that started with you. A journey, I would say, toward CDR, and to see the few steps that were taken and how a bit more concretely than some actions were taken.Rob Price 25:58I'll use a couple of examples that are not my clients, but they're well discussed, well documented, and in the public domain, if that works, which is probably, and they're both, well, both international organizations. So the first one is Merck and the work of Dr. Jean Enno Charton, who's head of bioethics and digital ethics at Merck. And I think, why do I start with that? A large organization, I think 60,000 people, something of that order around the world, but working in a space that's clearly got strong insight around regulation and controls because of the nature of what they do already. So there's almost a lot they would be, I think, one of the first types of organizations to start thinking about broader CDR and digital ethics in the wider round. And therefore they've focused in and put people and built a small team to build out a framework that takes the best in terms of some of the guidance that's around and early thinking around digital ethics boards and mechanisms and frameworks, and created something that they believe is right in their organization. And I've seen that build and progress. I've presented with Jean Enno in the past, and it is a very thorough process that they've gone through. The last conversation I had with him was interesting because having got that framework in place, that's right for them, it's then how do you communicate it across multiple countries, thousands of people, and effectively get that complete change on boarded and maybe enabling people to say, hey, this, this thing that I've spotted over here, the other side of the world, is something that's different. And maybe that's my introduction to the leader and the work that they did, which again, is one of the early pieces of work, as far as I was concerned, around CDR and led by Jakob Versner. And again, he put in place an explicit CDR. They had CDR principles that they defined for them. I think there were 14 separate areas that they identified. It was driven around digital transformation. So their starting point was every project that has a business case to progress anywhere across the business, we're going to interject, and this is the framework by which we'll analyze the consequential impact and look across the supply chain, very focused around sustainability and local community impact in terms of the societies, the farms, kind of in whichever countries, in whichever parts of the supply chain. And one of the things that I loved about that was that whistleblowing aspect. It was saying, look, there is no problem with being able to say, hey, I've spotted something we need to look at this. And I think that's such an important part of culture and maybe going back to the early conversation of transparency, giving people the confidence in an organization to feel that they have a voice. And I know we've put in this kind of marketing kind of brochure that we're net zero and compliant, but actually kind of, actually the proof points that we think we're quoting aren't quite right. I think it's important for people to be able to say that. So, I mean, there are many other organizations and much work that's been done, but I think both of those two examples are the ones that I'd give as well established on their journey using CDR and digital principles and continuing to evolve and build out over the last several years, rather than somebody just starting today.Aiste Rugeviciute 30:05If you are a smaller company, if you do not have 40,000 people and a lot of experts who can contribute with their knowledge and plan how CDR is relevant for you, that's a different challenge, right? For the smaller companies when they want to do something, but they don't know how to get going there. And currently, unfortunately, we are lacking tools or there's not that many frameworks which can provide. I emphasize a structured approach because let's be honest, people like to be structured. You know, they like to think in terms of some kind of systems and being clear about the steps which they need to do in order to get to the next stage.Gael Duez 30:54As you said, in a big company, you can indulge yourself to have a dedicated team working on this topic and elaborating fine tuned principles, thinking about how to deploy it, and bringing the leaders. But if you're a medium sized company, mostly it's a one person show most of the time and it's not even a full time job. So having a structured approach will definitely help. And this is exactly why I was very much interested in your maturity model. So the floor is entirely yours now to talk about it.Aiste Rugeviciute 31:32Yes. So CDR maturity models. So it's a proposition. It's not a normative thing, but it's a proposition which is a result of academic collaboration and work with different people, different organizations. And thank you, Gael and Rob, you were part of that for all the disclosure, as much as there were others around. In total, I would say 30 people who were involved in contributing with their knowledge, ideas, giving feedback at the different stages. So the maturity model, what I'm talking about, it's fully available online. There's an academic paper I still need to write, actually a more down to earth paper, practical explaining, because I understand that academic papers are not very easily readable by most people, especially those who want to go just quickly and apply it. But the idea of this CDR maturity model is actually very simple. It's a model which allows at the current stage, to look into the scope or help to define the scope at which an organization should look in order to analyze their CDR strategy or analyze their actions, currently, actions being taken inside of the organization. The model, as I said, currently is descriptive, so it's not very normative. It does have six maturity levels. So the idea is that you go from nothing at all. There are no actions being taken up to the six, which if you're exceeding, you are the innovator. You are at the front of this whole CDR movement. There are five dimensions, and within five dimensions we have 18 sub dimensions or 18 focus areas. So we have CDR governance that kind of stands itself clear and underlying there are three sub dimensions. And to be honest, CDR governance, it was one of the most easier dimensions to get consensus on. Almost everybody, all the participants, you know, they were, we do need that. We need actions, rules against the CDR, governments and strategy and all the planning. So that's the first dimension. The second dimension is the ecosystems, which means that as an organization, you should be doing something to contribute to the wider discussions of CDR or in general, digital sustainability. It could be through your relationships with your suppliers, it could be through participation in different external think tanks, groups, open source projects, etcetera. Then we have a workplace and culture. So that digitalization is implying, well, very rarely we will have an organization currently without technology in place, without having their collaborators being exposed to technology, and collaborators can be empowered with the technology. So one of the examples, you know, generative AI, it has a lot of potential to empower people, but it also comes with risks. So that's the whole coming back to the principles that technology can bring positive and negative impact. So I have a workplace and culture, you know, at what point people recognize the risks and opportunities and do they know how to act upon them? Then the fourth one is digital services or solutions. So it's all about dev teams. So internally, what kind of applications we're using, how we're developing, what are the processes in place, if it's relevant for a given organization. And then the fifth one, which is the most difficult, I would say, and this one still needs to be, I think, further developed, is infrastructure or IT assets. So everybody agrees that we do need to think about how we are dealing with data centers. What about our equipment? So IT assets are very much thinking about concrete hardware. But, and that's where the more complicated discussions. Cloud, for example, where does that fit in? Is it fitting in your infrastructure? Is it a more digital solution? Or is it an ecosystem? Because it's actually your provider? Right? So currently it's put in the model. It's under infrastructure, but the model is supposed to be a living model. So the model is there helping, hopefully helping practitioners, helping academics to structure the conversations about CDR. What's the scope? How do we evaluate the current state of our actions, in what areas? So they can be called capability areas. But we don't really give in to that model. We don't really give advice on how to reach the next level. So that would be a more normative model. So I hope that somebody will take it, you know, and as I said, it's a living model. It's supposed to be criticized, it's supposed to be, you know, people should hopefully engage with that model, propose next steps, evolutions, how we can apply it in order to plan the strategies more effectively.Gael Duez 37:45Okay, thanks a lot. And I must admit that I'm happy that the cloud was kept in infrastructure because I was a strong advocate of it and I had the opportunity to use it with a client. And actually I was kind of exactly what you've described. It's not necessarily super normative, but it was at the very early stage of consulting on green IT strategy. That was how it was labeled. And I remember I needed something to provide them structured feedback on the, I think it was 20 or 30 interviews I ran with their key actors. And it was pretty useful just to drop the visual representation and say, you know, as far as I understood with those discussions, here is where the main impacts are today. So it makes total sense because you're building digital services to pay attention here and here and that, etcetera. And it was a very loose assessment. It was not super structured with the metrics, etcetera. But still, it went straight to the point with my clients and the executives, like, okay, we got the big picture and then let's investigate a bit more on it. Which actually leads me to another aspect that both of you, you've been advocating quite a lot, is talking versus acting. I think it's very easy to get lost with a high level of conceptualization. And the CDR approach can help actually to get lost somehow if you deep dive into the details and you say, okay, and we should structure like this, and then create a substructure and then another substructure, and for each substructure we should get metrics and goals, etc, etcetera. And like ten years later, you've got a beautiful paper, maybe a white paper or an academic paper, but not that much action being done. And I know that both of you have got strong opinions about it. Maybe, Rob, you wanted to start, like, how do you use the CDR principles and the CDR approach to literally drive actions rather than discussion?Rob Price 39:48I think it's fascinating to actually kind of look at what is different, what is happening around the world and to understand relatively kind of the way in which change happens. I mean, the thing that I would say is organizations love to measure things. I mean, can they love to measure things from a financial point of view. But actually just over the last 20 years, I think many organizations, unless you can measure it, you can't possibly then do anything to change it. So I think it's really important to have some sort of model that enables organizations to assess where they might be. I just don't think that the answer is that everything needs to be 100. It comes back to choosing where to make the impact, because you've seen an assessment and a chart that suggests that there's weaknesses in certain areas and then for what you do about them, if I can talk briefly about the approach that I see in Switzerland. So Ethos, who were kind of involved in one of the early definitions back in 2020, I mean, they started measuring the top hundred or whatever number it is of Swiss businesses on a CDR index that they've defined. And of course, the first time they did it, everyone scored appallingly because it was a new concept. It wasn't the way that they'd been managing their business, if you like, but when somebody with a voice, and in the Ethos case, because of their involvement in pension funds and they've got a financial voice, if you like, in Switzerland, then organizations then think, well, we don't want to be scoring so badly next time, so how can we do some things to ensure that the score is better? So the first point is, measurement's key because that's what organizations get. Understanding the influence for change, whether it's government regulation, whether it's consumer behavior, whether it's somebody who's got an involvement in the investment decisions, in your long term sustainability as an organization, Ethos, as an example, there are different patterns as to why people choose to change, but then the question is, what do you do? And the answer in terms of what you do is in many cases do the things that are in the discrete area. I mean, if we're talking about the technology in a data center or in cloud CDR isn't inventing some different path that changes what you do? I mean, that's straightforward digital transformation. It's just trying to shine a light on is it being done in the right way? And I'm sure if, I mean, Gael, I remember Mark's session at the conference last year where he was talking about what is your true energy source? So it's about shining a light on you might have thought you were doing things in a way, but had you considered X, Y and Z? Because they're negative, consequential impacts that you just weren't thinking about, because you were just looking at it through the lens of head of IT, or head of compliance or GDPR, legal perspective, whichever one it is. But in each of those areas, there are things that can be done. So I almost see CDR as a pane of glass that you put across your organization that enables you to think about all that in connectivity between the things that are being done. Because what I see in organizations is people don't do that. People focus on the thing that they are responsible for, they know about, their passion is about, rather than that holistic view.Aiste Rugeviciute 43:35And I think that holistic view is also coming to the obsession with the measurement or the lack of holistic view is obsession with a measurement. Well, you gave a lot of different cultural examples, Rob. I come from France, or my current experience is very much in France, and here the measurement is very much obsessed, being a thing of people involved in IT. And I think it's almost a characteristic trait, you know, oh, we can measure how much cpu usage is this, we can measure how much this code is more effective than the other code. And all that measurement ends up being some kind of performance indicator, right? We can express the measurement in terms of money, we can express measurement in terms of energy consumption, in terms of maybe how many people we trained on CDR issues. But what actual value do those performances generate? That's the question which is often missing from the discussion. And I think that's exactly when you talk about the holistic view, we often forget that measurement or performance is not equal to the value. And what exactly we're talking to whom, you know, the value. So the value to the collaborators, the value to the future generations, value to your clients or your shareholders is not necessarily the same either.Rob Price 45:11I had a conversation a couple of years ago with an initiative that had put a framework and measurement in place. It wasn't a CDR, but it was very close to it. And I asked the question of how it is actually measured then? And the answer was a four month audit. And an organization is not going to do that as in what we're trying to do here. We're trying to impact the planet. We want every business, every organization, every government to be conscious about the way in which they use digital technologies. It can't be complex for every organization if we want everybody to do it, to do it. So how can we use it? I mean, I'm going to go back, maybe I am wearing my technologist hat here at this point, but finding ways to automate the measurement of those things that we're looking to assess. So that something can be done almost immediately with confidence as opposed to kind of misreporting, I think is critical to any of these succeeding.Gael Duez 46:20And is it also a question of accepting proxy metrics instead of final metrics?Aiste Rugeviciute 46:27This is the key, you know, to what granularity you need to measure things, right? Because you can get so obsessed and so you know what you're going to do with 400 KPI's. At the end of the day, you can measure very precisely how, how much of the resources your code uses. But if you do know that your code is creating, I don't know, negative impacts or creating addiction on a larger scale, well, all those metrics, they're not going to help you to actually make an impact or achieve something different, right? So I think sometimes we forget that experts or people working in the company can very quickly and for a pretty low price, I would say evaluate or estimate the impacts themselves. You know, they can. You just, you do need to provide some certain framework, you do need some certain performance indicators because otherwise people love it, you know, and that's how they measure the success of their company. So it could be a proxy used as money is often used as a proxy for any kind of indicators. But in order to act, well, you need to know priorities, you need to know the magnitude of the problem, but you don't need to know the exact numbers. If you know that you're using thousands of computers, but you don't develop or, you know, your website is just very rarely used, but clearly that the impact is more of your hardware, of the usage of the computers, instead of concentrating on eco design of your website. If it's not used by anybody or if it doesn't bring a lot of value, neither to your collaborators nor to your clients. And you don't need a very precise indicator for these to take action in this respect.Gael Duez 48:30That's why I love using the OKR framework because I think it sets two different levels and I use it almost all the time in sustainability consulting. Remember, what are the goals? Like the kind of medium term aspirational goals and this is really what you want to do. And then, yeah, well, you've got key results, but you can try to track them over a longer period to see if you're aiming in the right direction. But first have several of them, because unambitious goals usually should be measured in several different ways. And not, please do not use a north star, that is the worst possible thing to do, like having just one metric to understand the world, how stupid this is. And then and then also acknowledge, exactly as you did Aiste that, yeah, at some point we might drop a metric to keep another one and not end up with 20 or 30 different key results or KPI, to try to understand actually the real true goal that we have. We could be reducing carbons, we could be reducing water consumption, we could be having a positive impact on some kind of very significant social issues, etcetera, etcetera. But yeah, the question of measuring, and I know that it's especially true in France, but to be honest, it's quite also a very strong cultural trait in the US as well. And they love measurement. Just watch a basketball game and you will have statistics on everything. I'd like to drift a bit away from the implementation itself of CDR and to put on the table the topic of innovation. Because if we go back to the definitions that both of you gave at the very beginning, it was really the definition of CDR, I mean, it was really this idea of trade off that we need to know how much we impact the world, to know how much good net we bring to the world, and not just saying we're saving the world. So let us build ten data centers per week. But that's connected also with the fact that most of the time, with digitalization comes some sort of innovation. So what would be your stance on innovation and sustainability? Are they opposite most of the time opposite or are they complementary or is it a bit more complex?Rob Price 51:03I think something that a number of us were involved in, which was the Codes Initiative and the 22 report global action plan for a sustainable planet in the digital age. And the very simple part of that was it talked about three shifts that were important. I think the thing that was so important to me in the code conversations was that there was such synergy between everything that people were talking about there and CDR. It wasn't called CDR. I mean, CDR is in the report, but actually the conversations were the same and the three shifts put the enablers in place. So collect the data, collect the information, understand the impacts that we're going to be having. Protecting. Second, protect from harms, mitigate negative effects. Third one was to innovate to solve the world's biggest problems. In essence, those were the three things. Now, why have I said that, organizations, in my experience, don't like being told not to do something, and when they are told not to do something, then they don't want to spend any money on not doing that thing or to do something in a way that they're supposed to, as opposed to the way that they do do. And it comes back to if your model is based on addiction to maximize advertising revenue, because that's your entire kind of way in which you operate and live, then you're not going to suddenly stop that, are you? I mean, it's just not going to be there. So I think one of the things I hear a lot at the moment, and I'm firmly at the heart of the generative AI world and using those technologies is people focused around obsessing about quite recently harms, native facts. It is just doing things not very helpful or impacting people's jobs, etcetera, but forgetting about, because they obsess about that, forgetting about the potential power of those technologies, generative AI, AI machine learning, data science, etc, to solve the world's biggest problem. And we need that. The world has lots of problems at the moment. I mean, it's not just climate change, but finding a way to, I mean, just aging demographics is going to be a problem in terms of long term sustainability of organizations. I mean, sustainability in the largest sense. People can't get access to the people they need, etcetera. So we have to innovate. We need to innovate with a very conscious focus around minimizing negative effects and being aware of harms and all those things. But let's try and focus on positive impact. And I know from experience, impact measuring impact on people and communities is notoriously difficult to do. But let's be conscious of those things and absolutely focus on innovating because we have to. But with that consciousness about doing it in the right way, consistent with regulations, consistent in terms of, or thinking about the impact on people. But I am very firmly, I mean, you mentioned, I think at one point, Gael, that you've seen maybe an evolution in my thinking over the last two years, and I have, I am firmly in the, we have to use these technologies to innovate to solve some of the biggest problems that we've got, but with a very conscious awareness of some of the harms that could be caused. And yes, to think about how we kind of mitigate those.Aiste Rugeviciute 54:40I think this is the biggest challenge, how to innovate thinking about the system, about the global system, about the whole other potential impacts. Because if you look at the current strategist policy strategies or even within companies, right. All the strategies about sustainability, sustainable development, right. They are made in one line and then digitalization strategies are made in the other line and they're not really talking with each other. If you look, honestly, if even, I think the newest UNEP report on digitalization, they all talk how digital technology is going to empower and allow to achieve the digital development, sustainable development goals for sustainable development, you know, reduce some problems and so on, but they do not really talk about the potential negative effects that come with a digitalization. So currently in a lot of discourse, and that's what was really underlined in a digital reset paper report, which was published, I think, at last, in 2022. The policies do not talk with each other, and we need them to talk with each other. We need to ensure that digital transformations are aligned with sustainable development goals of sustainable development trajectories. And one of the things they are talking about in their report is exactly that. System innovations. That's what Rob was mentioning. So, innovations, first of all, I don't think that innovation should replace the word progress, which currently often is used instead of the progress we are using innovation. We used to talk a lot about advancing some progress and so on within the companies, and now it somehow got replaced by innovation, which is not exactly the same thing. Right? Whereas innovation, if we're using it as a definition, in order to come up with something new, in order to respond to the global challenges and global crisis, and we have a lot of those crisis currently. And I do believe as well, that technology has a lot of power, but it does have a lot of risks, associated risks. And we need to develop that capacity on different levels, on politics, on corporations, on individual levels, recognizing that technology is not neutral. We've been told, you know, oh, the technology is not neutral. No, it's not. Technology comes by itself with a negative environmental impact. I think one of the good examples is that because of the big data, because of the development in the algorithms, we have way more accelerated our knowledge of climate change. We actually can model things. We can understand it better because of the advances in it. So that's a positive thing. But now we know the problem is there. Now we understand very clearly where we are going. So it's time to shift and to use it differently and not to continue running huge calculations on something which we're not able or we don't have capacities to act upon. So I think that it's a very difficult change in mindset, because we don't like to think on a global scale. Right. It's difficult, I think, for us to think about positive and negative impacts at the same time.Rob Price 58:3920 25 years, nearly ago, I did some research around disruptive innovation, and I seem to remember a definition from that time that innovation was invention through commercialization. So innovation was nothing unless you found a way to make money from the thing that was being invented. And maybe we need to add with purpose or with an eye on doing it the right way to that definition. So it's not just invention through commercialization, but it's invention through commercialization with purpose.Gael Duez 59:13That's a beautiful definition. Well, thanks a lot, both of you. That was a very, very interesting discussion, especially at the end around innovation. I think we could have done another episode entirely on this topic, but I need to let you go to your regular life. So thanks a lot for joining. Thanks a lot for highlighting this very multiple aspect of a CDR. So thanks a lot and hope to see you in London in a few weeks.Aiste Rugeviciute 59:45Thank you.Rob Price 59:46Great.

You can find these notes on your favorite podcast platform, and, of course, on our website greenio.tech.Can the data center industry become circular? Simple question, very complex answers.Fueled by the ongoing artificial intelligence boom, data centers are popping up around the world like mushrooms after a good rain. For an industry which is more and more under scrutiny due to its environmental footprint, the sustainability angle cannot be overlooked anymore. Still, the main hurdle remains data, as many guests already stated in this podcast. Hence, my wish today to get insights from the program leader of an initiative which has managed to build high quality primary data on the data center industry. The CEDaCI project sounds like a Dan Brown book title, CEDaCI code to unveil all the mysterious power beneath our almighty data center industry. And to some extent, it's quite the plot. But I will let Deborah Andrews, Professor at London South Bank University and a two decades long veteran in Circular Economy and Life Cycle Sustainability Assessment reveal all of it. Hi, Deborah. Thanks a lot for joining Green IO today.Deborah Andrews 02:32Thank you very much for inviting me.Gael Duez 02:35It's a pleasure. It's a pleasure. And I have a very direct question to ask you to kick start our discussion. Did you start the CEDaCI project out of frustration somehow?Deborah Andrews 02:49Okay, well, first of all, thank you for calling CEDaCI. That's the Italian interpretation. We normally describe it as CEDaCI, but hey ho, it's an acronym for the Circular Economy for the Data Center Industry. And yes, there was an element of frustration. I had worked with researchers and operators and so forth in the data center industry on a number of research projects from about 2010, 2012, and was acutely aware that the sector was very fragmented. There was the most phenomenal amount of expertise in the sector, but people worked in silos and didn't connect with each other. And consequently, there wasn't a sort of whole systems approach to the challenge of sustainability. And the industry experts in each of the sectors were doing the best that they could for their particular sub sector, but there was no consideration of the impact that those actions had in their sector. What the impact on other parts of the industry were? So it was absolutely apparent that there was a need for a whole systems approach. And it was very timely in, you know, having spoken to people who subsequently became partners in the project, that they were also acutely aware of this challenge. But being in academia, I was very lucky, being sort of slightly outside the industry, to be able to bring various representatives, stakeholders, etcetera, from the sub sectors together without having any bias.Gael Duez 04:38And Deborah just could you illustrate, maybe with a few examples, what silos are you referring to?Deborah Andrews 04:45So, one of the first things that we did in the project was to carry out a very critical appraisal of the state of the art. In other words, we did a scoping review of what was going on in the industry, and we identified eleven key sub sectors, key players within the industry, starting with suppliers and then going through design, manufacturing, etcetera. But what we did was linked the silos, or found evidence that these silos actually were related to all the different lifecycle stages of data center equipment. Now, we focused on electrical and electronic equipment, because based on prior studies with a very extensive PhD that we ran in conjunction with HP, we found that the hotspot, if you like, the environmental hotspot, and this was looking at a whole data center. So the building or the services, M&E, etcetera. The key area of environmental impact was IT equipment, partly because of the embodied materials, the energy consumption, but also the short life of products, and in particular of servers. We found that they have ordered center equipment, and this was also reflected in a big EU report that informed lot nine that servers had the highest environmental impact. So that was the focus of the CEDaCI project. But coming back to the life cycle stages and so forth, and the various silos, then we have the installation phase. And use, of course, is incredibly important. Operational energy transport, taking stuff to and from data centers, perhaps taking to secondary market operators or recycling plants. Then we have data destruction, which could be through mechanical means, shredding, etcetera, or it could be more digital with software. And then ultimately we move on to the end of life. And we could say end of first Life, which leads to secondary market and reuse. This includes refurbishment and remanufacture. Ultimately, though, whether you send your equipment to secondary market suppliers or straight on for recycling, eventually all equipment ends up with end of life processes. Now, ideally as much of the product should be recycled as possible. But what tends to happen is that the low hanging fruit, things like the casings and so forth, as their steel and obviously external, those recycled and the majority of the PCBs aren't, they end up in landfill. There's a real need for a shift in thinking practice to manage end of life equipment. In this CEDaCI project, one of the key things, one of our USPs, was to bring together representatives, stakeholders from these various subsectors. But one of the points that came up, because we organized co-creation workshops as part of the project, to identify what stakeholders felt they wanted, whether what they wanted was in line with what we felt would benefit them, which was a tool to aid decision making about to help with the sustainability profiling companies and so forth. But one of the USPs brought together these people, and then invariably they commented how much they had learned through the co-creation workshops, because they didn't talk to people who worked in other sub sectors. So this, again, you know, from a sort of academic or life cycle thinking perspective, you need an absolutely whole systems approach to the challenge of whatever industry you're working in to develop a circular economy. Because every action at every life cycle stage, etcetera, has caused an effect. It has an impact on all other life cycle stages.Gael Duez 09:27Okay, so there are so many things to unpack here from systemic thinking and your systemic approach, like the benefits of co-creation, and also what you've mentioned on e-waste. And if you, if you indulge me, I'd like to deep dive about this end of life differentiation that you just made. The first end of life, and then the second and eventually the final end of life, which is when the electronic equipment becomes e-waste. It's very important because I see today in sustainability criteria applied for RFP or bid, etcetera, or auditing the data center industry, or auditing hyperscalers, that more and more they kind of tick the box of all servers are donated to charity. All servers go to the second hand market. And so we're good, job done. I think it's a bit more complicated than that, because if the server is donated, but one year later, it ends up in a landfill somewhere in Africa, Southeast Asia, South America, or even Europe, that's not really a solution to the problem. So my question is, how important is this distinction between the first end of life and second end of life? And is it today enough taken into consideration on how to assess the sustainability of the data center industry?Deborah Andrews 11:02Okay, so let's think about equipment, and in particular, servers, which I've said have the highest embodied impact of data or data center equipment. And the technology, obviously, whether it's memory, processing speed, whatever, is developing incredibly rapidly. We won't even mention AI at the minute, but the sub-technical change means that an awful lot of equipment is replaced while it is still working. You know, it's functioning very, very well. Can understand, in a way, why hyperscalers and other bodies may want to have the latest, fastest, best memory, etc, equipment. But what on earth happens to the stuff that comes out of hyperscale and other centers when it's still working? Why would you want to recycle anything, take something out of service, recycle it when it still functions very well? So there's obviously a very key concern is memory and disks, be they hard drives or solid state drives. What happens to the data? We'll come back to that in a minute. But there are initiatives to encourage use of second life products, products that are still very serviceable. I mean, that's, I suppose, quite a nice analogy, in a way is, and let's assume they're all electric vehicles rather than fossil fuel driven. But, you know, maybe the hyperscalers want Ferraris, when actually many other industries would… something like Fiat Cinquecento or VW Polo will meet their transport needs. Okay, so there are drives. And certainly, I know in the UK, government and organizations like the NHS are really encouraged to use secondary market products, which one of our partners, Techbuyer, a company that is linked to them, interactive, they did a massive amount of research for their own business, but also the research fed into the CEDaCI project, they found that there were a lot of myths around the performance, particularly to do with operational energy, the performance of old, within three years old, and brand new products. If the equipment is set up correctly, then the difference in energy consumption is negligible. Obviously, it depends what compute activities you're engaged in, but like for like, energy consumption, the level is negligible. The OEMs, of course, want everybody to buy new equipment, so they're always saying, “Oh, it's better, you know, it's faster, it's more efficient, blah, blah, blah.” So coming back to the car analogy, an awful lot of public bodies in the UK, and probably in the EU as well, are being encouraged to use second life products which meet their technical needs without any problem whatsoever. But the good thing about this is the secondary market, we should have the products there, and this is a key element within the circular economy as well, of course, because it's not just about recycling at the end of life, it's about extending product life. As I said previously, why would you want to take a product out of service that is still functioning and can fulfill somebody's requirements? I think the key statement around reuse is keeping something in service for as long as technically and economically viable. That's really, really important. So the secondary market is various companies have been set up to collaborate with big hyperscale operators or smaller operators and are promoting good practice, I think, in terms of circularity and economics and resource efficiency, there are some challenges there to do with legislation and ensuring that second life products have the same warranties and so forth, and also to do with data security. Ideally, we should simply wipe drives, be they solid state or hard disk whatever, and reuse them. But there's a lot of anxiety about data security. So organizations like banks, for example, insist that drives are shredded on premise. They don't leave the bank once they're there, they come in as new products and they end up leaving as bags of tiny little bits of metal. They're shredded on site to ensure data security. But I think, and again, there are a number of really good research projects ongoing looking at data security and performance of either software wiping, whatever, so that hardware, HDDs and SDDs, SSDs can be reused.Gael Duez 16:25Are you optimistic about the fact that even for highly secured working environments like banks or even the military, software wiping will prevail at some point?Deborah Andrews 16:38I'd like to think so. I mean, I'm not an expert in this, but I would like to think so. And I think the more really robust and empirical research that can be carried out to reassure end users that software wiping or equivalent is safe as shredding, the better, really. So, yeah, fingers crossed.Gael Duez 17:05And Deborah, you were mentioning that there are a number of companies that have been set up to meet this new market. Could you share with us some trends? Is it still marginal, or are we witnessing a boom in the second hand market of professional IT equipment?Deborah Andrews 17:23It's really interesting. I think it depends very much on time, place, circumstance, etcetera. So it was interesting. During COVID for example, there was a marked increase in demand for second life products, partly because of the increase in demand for data center industry services due to homeschooling and home working, for example, but also because there were supply chain issues. And if you remember, there were all sorts of problems with chips, etcetera. So once we got over Covid and the industry really kicked off again, back to normal business as usual practices. I'll give you a little anecdote here. Okay. There was a bit of an issue around the secondary market because some manufacturers had lots of new equipment in stock before COVID but they hadn't, for various reasons sold it on.So when there was a sort of shift in business practice generally around the world, a lot of the big manufacturers suddenly decided to flood the market with new equipment. And the price difference between that and reused equipment was negligible. So of course people wanted all purchasers, procurement teams wanted new equipment. So that had a really adverse impact on the secondary market for some companies. I'm not saying all, and it ist anecdotal, but I think it looks as though new and secondary markets are very subject to influence from external factors. You know, they're not as consistent, as stable as certainly the secondary market as we would like it to be.Gael Duez 19:28Did you explore with the CEDaCI project, the potential lifespan of servers if the second hand market were to be a very well functioning market? Because I've seen some colocation service providers starting to claim, and I congratulate them for this, that they keep their server for seven, sometimes eight, sometimes even nine years. But can we do better? Can we imagine a world where a server would last for 20 or 30 years? Or would it make any sense?Deborah Andrews 20:04First of all, if your server, and it's like, you know, your car, your Polo, your Fiat Cinquecento, whatever, even your Ferrari, if it's working well, then you should be able to keep it in service, in life or operation for a long time. The big challenge is when things, parts start to wear out or break, for whatever reason, they fail, you need to replace them. And a lot of manufacturers don't keep parts. In fact, I think legislation at the moment stipulates that manufacturers only have to supply parts for up to eight years. So if you have a ten year old server, where are you going to get the parts? It could be that you go to, say, a secondary market supplier and they have parts, but it becomes increasingly difficult over time to replace components. So that's a big challenge. The other thing is looking at changes in compute capability. We know that, for instance, there's all sorts of issues around whether you go for air cooling, to go for liquid cooling, is liquid cooling more efficient, etcetera. And AI increases the operating temperature of components. So that may well mean that we have to redesign service to manage factors like that. As compute changes, we actually need to reconfigure either layout, or if you are going for air cooling, then the number and type of fans that you have or you switch to liquid, whatever is most appropriate. So in theory, if we had modular servers that you could take out certain components of and replace with upgraded components that had common connectors and, you know, the box, the space required to house them was the same, then it seems you should be able to keep servers. You know, even if you end up with everything, all the internals, the guts of the server being replaced, the chassis, you should in theory, be able to keep reusing that for perpetuity. But whether that's feasible or not, because of changes in shift from expert liquid cooling, whatever is, we need to think about that.Gael Duez 22:40And before talking about the main results of the CEDaCI project, and as you mentioned, what all the stakeholders learned from each other, I've got one final clarification question. Because you were very assertive that the embodied environmental footprint within equipment is by far the biggest share of the overall environmental footprint of a data center. And if this position is not a debate at all when it comes to end user equipment or devices at home, whether it's laptop, smartphone, etcetera, etcetera, I heard some different opinions where it's more like 50-50, because professional equipment lasts longer. Some people advocate that actually the use phase, and especially the energy consumption during the use phase is far from being negligible. And for some of them, it's even the majority of the environmental footprint. So maybe could you clarify whether you were mentioning only the carbon or other environmental impacts, or even maybe the carbon. Your calculations make it clear that embodied carbon is even bigger than energy consumption, GHG emission. I was looking for a bit of a clarification here where you stand on this debate.Deborah Andrews 23:59Okay. So when we said that in our calculations that the largest impact in the data center was the IT equipment, when we said that the largest impact was the IT equipment, we based our model on a data center that lasted for 60 years. The actual infrastructure, the building, some of the M&E, was replaced after 20 years, etcetera. But the IT product life was based on three to five years, okay? And that's for hyperscalers, that's a long, long time. Although Google now says that they're going to keep servers in life for five years, we'll see about that. So coming back to... So i if you decide to pull your data center down after 20 years and build a new one, then that ratio of impact from IT to building will change. But just be clear about that, okay. The second thing to be really, really clear about is the kind of metrics you use when you are looking at impact. So carbon, obviously, and carbon equivalent, it could be methane or other hydrocarbons. Carbon is only one metric, carbon and carbon equivalents. And you exclude a whole array in fact, thousands of other impacts and outputs, inputs, etc. And impacts, when you only look at carbon and carbon equivalent. So you're not thinking about the impact of water, the impact of gold mining, for example, which is incredibly toxic, the tailings can be, may have one of the highest environmental impacts, etcetera. And the impact is not just environmental impact, it can be very detrimental to ecosystems. So toxic substances, mercury, arsenic, etcetera, used in mining processes will obviously have an impact on people living in the area if they get into the water supply and into soil and so forth. So if you're looking at carbon, you exclude all of those factors. I'm not 100% against carbon assessment. I just think we have to think about it in relation to everything else. It was really, it was the original sort of metric linked to life cycle assessment dating from the 1960s. So when LCA first began, it just considered energy, be it operational or embodied. And that's where the linked carbon assessment comes from. It's incredibly important when we're thinking about climate change. We can't underestimate its significance. However, we do need to think about all the other impacts as well. So we carried out some studies of exactly the same piece of equipment, one looking at carbon, operational and embodied carbon, and the other looking at a comprehensive life cycle assessment, which looked at and included thousands of inputs and outputs. But just on a carbon study, we found that operational energy, when you're looking at lifespan, let's say five years, operational energy accounted for 85% of impact, or the carbon in the operational energy, 85% of impact, and embodied in energy was only 15. Okay, so with the newer equipment, that ratio shifted a bit and the sort of makeup shifted to 20% for embodied impact, and 80% for operational impact over a five year life. So it's no wonder that when the data center industry is being guided by, you know, the need to reduce carbon, be it embodied, operational, it's no wonder that you focus, the industry focused on operational energy initially, and also I think it's easier to manage to make change. So now we see, you know, more use of renewables, etcetera. And also improved operating efficiency of equipment itself. When we look at comprehensive life cycle assessment, we've got a couple of surprises. We didn't think that the difference between carbon and full LCA would be so significant. So the same piece of equipment or two pieces of equipment. The first was, as I said, a really old server, and the ratio of operational to embodied impact was about 80:20 for carbon assessment, and again, it was lower. It was, I can't remember something like 75:25. But what, this is the really, really, really key finding. When we looked at the comparatively new piece of equipment, which was from about 2017, we found that the embodied and operational impacts were about the same. It was about a 50:50 split. So that was really, that means, that was a real surprise. And it really highlights the necessity of examining, measuring, monitoring, you know, improving the physical resource efficiency, increasing use of recycled materials, increasing recycling processes, and building a decent infrastructure to do that, changing practice with things like encouraging, if you can't reuse a whole piece of equipment, can we harvest components and reuse a individual components, etcetera. So that was a very revelationary, very revealing study.Gael Duez 30:15This shift from 80:20 to 50:50 was mostly due to energy savings, energy optimization of newer equipment, or was it also, as you said, because of lower cost of building equipment, thanks to the use of recycling materials, etcetera, etcetera.Deborah Andrews 30:36Okay, so this 50:50 split, it was a lot to do with improved operational energy. When you're looking at the full life cycle assessment, you are considering things like what happens during mining processes. It's not just the energy or the toxicity, etcetera, and also things like what percentage. Well, now we should be thinking about the percentage of recycled materials included, that, in theory, should reduce environmental impact.Gael Duez 31:14So now that we laid the ground for a better understanding of all this environmental footprint, etcetera, let's go back to the actual findings of the CEDaCI project, both for the stakeholders, but also for an average, I would say, data center operator. What are the findings he or she should be aware of? And what about this tool that you developed called the compass?Deborah Andrews 31:38The CEDaCI Compass, the circular data center compass. That was a key output from the CEDaCI project. And the majority of the research that we did underpinned the development of this digital tool. It's free to use. You can find it, access it via the project website at cedaci.org. The idea was that we wanted to help people working in the industry to make informed decisions about how to support their transition to sustainability and circularity. And one of the things that we are very keen to do well, apart from being absolutely objective, it's completely non judgmental. We don't offer any, you know, this is right, this is wrong. We just present the results. One of the things that we did as well was to separate out the three sorts of tenets or pillars of sustainability. So you put your information into the tool, or you select various criteria, and then when you see the results, comparing two different servers, you can compare the environmental impact, the social impact, the economic impact, so that, you know, it could be, as an operator, you're more concerned about social factors than environmental, so you base your decision on that. Or I would imagine most people think about economics as their priority driver. But, you know, being aware of the other criteria is really important. If you lump together, you know, these three key tenets of sustainability, you get slightly inaccurate results, you know, you don't know what I mean. It could be the social impact of one server is very high, but its environmental, adverse environmental impact is very low, or the other way around. So that's why we separated those points out. The other thing that we included was a criticality indicator. Now the EU and, well, UK to a certain extent, but certainly the EU has become increasingly conscious of resource efficiency and has identified, now, 30 materials that are what they define as critical. This is because of the amount of resource that is as yet unmined in the surface, the amount of material that is currently recycled. And I would like to include as well the possibility of substitution. But the other really, really important is the geopolitical factors, where on earth is the material located? Because that has a very significant impact on availability. So the critical raw materials are basically defined as those that are of major technical and economic significance to the EU and UK. So we included a criticality indicator to raise awareness of these materials. The use of these materials in data center equipment, all electronic equipment, uses some critical raw materials of some type. We cannot make, for example, mobile phones without tantalum, which is essential for capacitors. Tantalum is mined in Central Africa, mainly in DRC, Congo, where mining practices are eye wateringly horrific. They are environmentally and socially damaging. So we wanted to raise awareness of those sort of issues as well, to encourage better practice. So the compass was developed. As I said, it's a free to access online tool. And it was basically to inform potential end users about the impact of their choices. The other thing that was really, really important at the moment, we don't have anything like the scale of recycling infrastructure that we need to manage all the equipment that's currently in circulation, let alone all the electrical and electronic equipment that will come into the waste stream imminently. We've got a huge problem with this. There's a collection globally and it does depend where you are based globally and as does reuse. Incidentally, people with less expendable income tend to be more frugal by necessity rather than intent, I think or wish. Overall, the collection rate of e-waste is less than 20% globally. And that includes consumer as well as commercial products. But we don't have anything like the infrastructure that we need to recycle this anyway. The recycling processes at the moment, they focus on anything with iron in it. So steel, copper, aluminum, and gold. And there's not very much gold, you know, by mass, it's comparatively little gold in electronic equipment. But of course, its inherent economic value makes it attractive to recycle it. So there are masses and masses of materials, many of which are critical on the critical raw materials list, which aren't recycled. Unless we get our act together and develop a proper recycling infrastructure, there's significant potential for disruption to supply chains.Gael Duez 38:54But do you believe it is possible? My understanding of the chipmaking industry, or even slightly less complicated part of the IT industry, the design itself is so complicated, is so… the different metals are melted together to create alloy. You've got ceramic, etcetera, that I don't even know if it's feasible to recycle the way I would say the average John do understands it, which is we will extract to reuse it the same way. And it's more down cycling or it's even. I mean, I honestly wonder if recycling is really the way forward. So don't get me wrong, instead of being able to reuse for super long period of time, as you previously mentioned, having components that are interoperable on open standard etcetera, and saying, okay, you know, this memory card might be 20 years old, so it's ridiculous the amount of data you've got. But hey, I've still got half a billion of them. And if I've put them in some racks, it's still a decent, you know, decent enough, or whatever. But my point is, I think we are fighting an uphill battle if we really want to recycle, like extracting the tantalum you were mentioning, or the cobalt or whatever, rather than redesigning our industrial process and making also sure that the warranty period is so big that so long, that actually we shift the burden of recycling to producer, which are eventually, ultimately responsible for putting things on the market that are absolutely not recyclable. And that would end up being e-waste in a matter of years rather than decades. And when you see the environmental footprint of everything that you describe, we should talk in decades rather than in years. But that's a personal opinion. Sorry, but my point. What do you think about the feasibility of recycling? Or are we talking about a slightly different approach in the recycling industry for the IT equipment?Deborah Andrews 41:05I think we need to have all of those things, really. I don't think there's not one size fits all solution. I think there are some really massive challenges with electronic components, for example, because of the way that they function. You're looking at atomic levels, the way that if you're creating signals, etcetera, the way that atoms and the subatomic particles behave. So that is obviously going to limit the way in which components are designed and manufactured at the moment. Maybe in the future they will discover different approaches to data transfer or signaling, switching, whatever it may be. I don't know too much about quantum, and I don't know how this is going to change things, if at all, if we exchange one set of problems for another. I don't know, but I'd certainly like to find out an awful lot more about it. But coming back to your question about end of life and so forth, I absolutely agree that we need a different approach to the manufacture of many products. I think we need to really focus on the things that can be upgraded, swapped, repaired, etcetera. Again, most or many electronic components, it's nothing. You know, they're so tiny, it's impossible to repair them. So focus on the stuff that we can repair and upgrade and keep in service for as long as possible. The other stuff, we need to certainly develop better recycling capability. But there's an argument that's put forward that some of the materials, the economic value is fine if you have a kilo of stuff, but by mass per component, the mass in individual components and in servers as a whole is very low. So the economic value of any particular materials reclaimed from the server will be low. So we need critical mass to make development of recycling and reclamation technologies for particular materials economically viable. That's going to be the driver. The other big challenge we've got with recycling is sometimes the processes, and we're not. You know, there are lots of ways of doing this. One of the partners in this CEDaCI project, a company called TND or Terra Nova Developments, they developed some new recycling processes to reclaim materials that aren't commonly reclaimed. And they use a mix of thermal and chemical processes. And because you're using more than one process, of course, that increases cost. But, you know, if you have critical mass of stuff coming through the system, it does become economically viable eventually.Deborah Andrews 44:23One of the big challenges is very often, but if you have a printed circuit board with a huge number of materials, embodied materials, you're processing to reclaim one or two or three, those processes can damage other materials, and so you can't reclaim those. So, you know, I think at the moment, it's impossible to reclaim all of the materials in PCBs, which are the biggest challenge for recycling. So I think we need to think about when we're designing, not just designing for here now and in use to design, thinking about how can these things be easily disassembled to facilitate, if not, you know, chucking the material into a smelter to recycle it, but actually being able to reuse the materials in the… as soon as we take them off one product, we can put them on another.Gael Duez 45:22Do IT equipment manufacturers today start to tackle the issue? Or are they still mostly in the business as usual approach and not at all incorporating, as you said, a repairability aspect when the design sinks, even a bit of a recycling aspect?Deborah Andrews 45:45I think there's, and I'm not going to highlight particular companies, but I think there's quite a lot of smoke and mirrors and greenwashing. And this, again, it's anecdotal from personal experience of, you know, I worked through this CEDaCI project. They all still want to sell new equipment, and certain companies say that they have a kind of closed loop, but it's a very open closed loop, shall we say? They're not responsible. They do take equipment, but then they sell it onto secondary market agencies. They're no longer responsible for that equipment once they've sold it on. There's a real need to shift thinking and business models and possibly, rather than selling IT equipment actually to sell services. So, you know, you rent, I don't know whether you do it by compute capability or operating time or whatever. So then they're responsible for maintenance and for what happens, either for extending life, which would be very much to their advantage, or for recycling at the end of life.Gael Duez 47:00Which is what is slightly happening with the big three hyperscalers because they've started designing their own servers. And I could bet that they thought about the fact that even from a financial perspective, the longer you keep this equipment, which is on your own cost base, the better it is for your bottom line. And I have a final question for you, because you're privileged witness of the data center industry for almost a decade, two decades almost now, and there is a bit of an elephant in the room that you actually, you teased us several times during the interview about AI and more generally, I would say, about the trends. And I would like to share with you an anecdote while I was recording this very enlightening episode with Professor PS Lee in Singapore, who's one of the best experts in the water cooling techniques and more generally on building energy efficient data centers, especially in tropical climates. We had a really fruitful discussion, and he's a big advocate of technical optimization, and he knows a lot about these topics, etcetera. And at some point in our discussion, he posed, and he had this kind of overwhelmed moment, you know, when you've got just too much weight on your shoulders. He was like, but you know, Gael, at some point we will have to ask also the question of the level of consumption of compute that we want in our society. Because despite all the efforts that I'm doing to reduce energy consumption, the current trends, and especially the AI boom, I don't see how I can make it. And it was this kind of face, like, I simply don't know how I will be able to manage such an exponential consumption in energy, even if overnight all data centers in the world would switch to water cooling, super efficient water cooling techniques and whatnot. And it kind of struck me like even someone within the tech industry and such a strong advocate of technical optimization saying, wow, but the trend is really worrisome. Is it something that you're aligned on, or are you a bit more optimistic about the current trend in the data center industry?Deborah Andrews 49:29I think it's really scary. Forget about the ethics and what AI can and can't do. Forget about that. I think it's really scary because it seems that the industry is racing, racing forwards to develop either new data centers, new equipment to manage AI, etcetera. But my feeling is that some of the, what we've learned, good practice, etcetera, is forgotten in that race. So it's a business as usual approach. Build, install, run, replace, run. It's very worrying because the physical resources and energy required to manage AI operate, even the simplest operation, the demand for energy, is astronomical. So there are arguments saying, oh, well, AI is going to measure this, that and the other, and improve, you know, this, that and the other, but, or improve the operational efficiency of this, that and the other. But I don't think we've done any kind of calculations at all to see whether the benefits of running an AI software or, you know, program activity, whatever, to assess resource efficiency, whether the benefits achieved through the resource efficiency or more significant than the impact of running the AI operation. We need to really, and it's not going to happen, but it would be great to pause for a year and just to sort of examine some of these factors and to see where the benefits of AI really lie. So if we do carry on business as usual, and I know there are various regulations coming in from, you know, digital sustainability and so forth in the EU, but I don't think they're going to have a massive impact on, certainly the speed of development of AI is far faster than the implementation of these new regulations. But the other thing that's worrying, if there are constraints of operating in the EU, for example, does it simply mean that providers will go elsewhere, they'll build in locations where the regulations don't apply. And so we move our problems to another part of the world. In effect, you know, more buildings in Africa, Asia, South America.Gael Duez 52:05And from a cold financial perspective, do you think that the current trend of building data centers everywhere in increasing compute capacity is sustainable? Or do you foresee some bottleneck or even some forced pose because of resource exhaustion?Deborah Andrews 52:25There may be a quantity crunch, unless we think about extending product life, as we've already mentioned, and recycling, reclaiming more materials, changing business practice, business thinking. I think that there's potential for quantity crunch, but whether operators will start to charge for access to digital services. I mean, at the moment, you know, you buy your phone, you have a package, and you can contact anywhere in the world whenever you want. Okay, you pay for apps and so forth, but actually you're not really paying very much for the digital services that enable those apps to function. And a lot of things are free anyway. So will we have to pay for digital services? Is that one way of monitoring or constraining digital activity or not? That's one question. But the other thing is, is it ethical? You know, if we think we're in a luxurious position in Western Europe in terms of economics, although there are people in digital poverty, but, you know, generally, as a child or a university student, if you don't have computing equipment at home, you can go to your study institution and access digital technology there. But that's not the case in many populations in developing countries where digital tech is a luxury for the upper echelons of society. And yet we can see how access to a phone, not smartphone, just an ordinary old fashioned phone, has empowered women, for example, helping them to set up businesses and so forth. Is it right to charge them for data or do we make data charging… is it sort of socially stratified or according to income bracket? I don't know. I think we need to be a lot more visionary, look forwards and be proactive and anticipate problems and design them out before they happen.
