#26 - Digital Sustainability in LATAM with Catalina Zapata and Ismael Velasco

This episode is not in Spanish or Portuguese but it might have been 🙂 With Catalina Zapata - founder of La Web Verde community in Colombia - and Ismael Velasco - founder of the Adora foundation and based in Mexico - Gaël Duez explores the momentum of Digital Sustainability in Latin America as well as the pitfalls it faces. From COP21 memories to the structure of the IT industry in LATAM, both guests share unconventional wisdom as well as tips for any IT workers based in LATAM to green the Web. Learn more about our guest and connect: Catalina's LinkedIn and WordPress.tv resultsIsmael’s LinkedInGaël's LinkedIn Gaël's website Green IO website 📧 You can also send us an email at greenio@duez.com to share your feedback and suggest future guests or topics.   Catalina's and Ismael’s sources and other references mentioned in this episode:ClimateAction.TechWordPress Sustainability Community Adora foundation  Elena Morettini’s talk Gerry Mc Govern’s workTom greenwood’s Curiously Green newsletterUnitar’s article on Latin America’s e-waste management  Article in Portuguese: Green Information Technology practices in University educational institutions: A systematic reviewCSIS article on The Development of the ICT Landscape in Mexico: Cybersecurity and Opportunities for Investment Environmental Variables - The Week in Green Software: episode with Chris Adams and Ismael Velasco Green Web FoundationTranscript (in English - for Spanish check below)(00:09) Gaël: Hello everyone, welcome to Green IO, the podcast for responsible technologists building a greener digital world, one byte at a time. On Green IO, we explore how to reduce the environmental impact of our digital world. Our guests from across the globe share insights, tools, and alternative approaches enabling people within the tech sector, and, beyond to boost digital sustainability.More than 300 million digital users, home of dozens of unicorns, with vibrant tech scenes scattered across the region. 2.2 million working in the technology, internet and communication sector, according to LinkedIn. No, I'm not talking about Europe, but Latin America. Latin America, which is a significant player in our digital world and as such a significant contributor to its environmental impacts. Just following a non-rigorous approach based on the number of its users, but hey, remember that the majority of the environmental impacts come from both manufacturing and user devices, and the electricity consumption of these devices. So, resuming my on-the-go analysis, with 5.5% of world users, Latin America’s carbon footprint for its digital activities would be around 77 million tons of CO2 (2019), which is more than any country in Central America, apart from Mexico, obviously, and for instance it is more than Uruguay has emitted. So, I guess now that you understood that today's episode is about Latin America, and more specifically, how someone working in the digital sector and based in Latin America can contribute to decarbonizing the Internet.To help us finding the answers, I'm pleased to welcome two guests today. Catalina Zapata, who's based in Medellín, Colombia. Catalina is a seasoned web designer who started a project called La Web Verde, (my pronunciation is terrible because it's in Spanish) in order to democratize sustainability on the web, teach designers and developers how to create more sustainable digital projects and more specifically spread green awareness about our digital footprint within the WordPress community. (02:34.39) Gaël: I spotted Catalina in this vibrant WordPress sustainability group last year, and when I reached out to her, she told me that she was already a regular listener of the podcast. And when I asked her why she was so much into sustainability, she had a very straightforward answer: because we breathe the same air and we are all on the same planet. And that was pretty straightforward. Well, later, she actually told me that three years ago she read an article about internet being the fourth most polluting country in the world, and that was kind of a ‘ha-ha’ moment. But actually, I think I even love better her first answer.Ismael Velasco is based in Mexico and I met him via the amazing CAT community. Ismael is a veteran in the software industry at large, and green software in particular. His API ‘graceful degradation’ concept immediately appealed to me, but I discovered someone whose knowledge and commitment goes far beyond green IT, with his involvement in the Adora Foundation, which forces social innovation across the globe and his recent decision to focus more on the sustainability side of technology. So, welcome Catalina, welcome Ismael. Thanks a lot for joining Green IO today.(04:02) Ismael: It's great to be here. Great to be with you.(04:05) Catalina: Thank you, Gael, for connecting, for inviting, and creating this space, that is not only innovative, but also is very, very, very necessary for those who design the web and consume the internet.(04:18) Gaël: Wow, thanks a lot, both of you. I would love to start, actually, with a very straightforward question. Is the title of this episode all wrong? I mean, is Latin America a pertinent scope to apprehend Tech and sustainability? Ismael, do you have an opinion on it?(04:40) Ismael: I think, personally that, yes, it is a meaningful category. I think the distribution of technology and the role and contribution of technology does diverge regionally. So; each country, each area will have different profiles. But I think the main realities facing Latin America in relation to technology do have a lot of parallels. I think culturally, there is probably even more commonality across Latin America than there is across Europe, in many areas. The tensions that we experience are often also mirrored across countries. So, I think it's definitely a meaningful category, which is not to say a homogenous one. I think you will find enormous diversity country to country. But I don't think that negates the fact that addressing the reality of technology at a Latin American level makes sense on very many levels. So yes.(05:45) Gaël: Catalina, do you have an opinion on it?(05:48) Catalina: I think that in Europe, digital sustainability has become a priority for both government and business. But there are strict regulations on the energy efficiency or data centers, the recycling of electronic devices, and the reduction of carbon emission in the technology sector. The United States has not reached European standards, but there is a growing awareness of carbon footprint reduction. But in Latin America, we have a great challenge in accessing resources and knowledge, and access to information in Spanish is limited. It is necessary to translate and adapt resources into Spanish and other native languages of the continent, to make the information more accessible and usable. However, I believe we have great potential, but more awareness and education is needed from all of us who create the web and consume the internet.(06:57) Gaël: Well, that's very interesting feedback, Catalina, and there are a lot of different things to unpack here. So we'll go back to them point by point, but I'd like to bounce back on what you've just said about the level of awareness across the globe. What is the level of awareness according to you about digital sustainability in Latin America?(07:19) Catalina: For me, it's very, very, very low. Digital sustainability is a strange concept in Colombia and Latin America. Everyone talks about climate change, net zero, circular economy, sustainable development goals, sustainable fashion, human rights, green mobility, recycling, inclusion, female empowerment, artificial intelligence, eco-tourism. But no one talks about green software, green web, or the impact of the internet on each of our digital actions on carbon emissions. And I ask myself why. To give you an example of how ignorant we are. I am an ambassador for the Climate Reality Project. It's a non-profit organization, one of the largest communities of world climate leaders of the world created to promote solutions to climate change. This organization has a virtual platform where everyone can connect with other leaders. There are materials, videos, forums, events, resources, surveys, discussions, seminars, virtual meetings, job opportunities. And for the last three years, I have not found a single conversation about digital sustainability or sustainable web design or digital sovereignty. The server where the website and digital community is hosted is not a green server. That makes a lot of inconsistency between what is said and what is done in companies or organizations or change makers in Latin America.(09:09) Gaël: That's not the first time I hear someone saying that digital sustainability per se, not sustainability at large, because a lot of stuff is obviously going on in Latin America, but digital sustainability is not a hot topic. Ismael, is it something that you agree with, especially with regards to the situation in Mexico?(09:29) Ismael: Yes, I think I recognize that situation, and I think it's probably the case for almost all of Latin America, with the exception of the academic sector in Brazil. But in Brazil, you do have quite a lot of academia that has been publishing for years. They've been, I think, some of the earliest thinkers around brain computing and digital sustainability. But they are the exception. And I don't think even in Brazil it has expanded outside of academia into industry in any meaningful way. In Mexico, a bit like we heard for Colombia, I've organized a number of events here on ‘greening your software’. I've given a few talks, etc. I'm in touch with a lot of developer communities here, in the thousands. And I think every single time, without exception, when I brought up the theme, it has been the first time anyone remembers ever having come across a talk or an event dedicated to the subject. But, like Catalina mentioned, there aren’t really any accessible resources in Spanish. There aren't bodies that are pushing for it. There isn't a regulatory or a policy agenda for it. And the people who have thought about it have tended to think about it in isolation. We've been trying to start building communities through a set of events around ‘Green Your Software’. We launched one in Mexico. We're hoping, with Catalina, to do something like that in Colombia too, and also outside of Latin America too. But generally speaking, I would say that, like Catalina, my experience is that the topic is highly resonant. The moment that people hear about it, developers in particular, they go, ‘ah, that makes sense’. I want to do something about it. But it's almost always the very first time they've thought about it. The level of awareness is extremely, extremely low, with the possible exception of Bitcoin, which has got such a globally bad reputation environmentally, that it has permeated the popular consciousness. And people might go, ‘oh, yeah, Bitcoin might be bad for the environment’. But outside of that, I don't think it's a discussion that is happening in general.(12:04) Gaël: So how come we are facing so many issues? Catalina, you mentioned that a lack of documentation in Spanish was one of the issues, but is there any other hurdle that a designer (because you're more on the designer side) faces, to start greening the web?(12:28) Catalina: I agree with what Ismael said, that the principal problem is the awareness. Yes, many companies and professionals in Latin America are still aware of the environmental impacts of their online activities. The lack of education and awareness about digital sustainability is a key challenge for those of us who create and consume internet content. Another very important point is the resistance to change. Some companies and professionals may resist to change, especially if they believe that adopting sustainable practices could increase their costs or require additional efforts. Another point is green hosting challenges. At times, selecting eco-friendly hosting provided by renewable energy sources can be a challenge, as there may be a lack of available options in certain areas and costs can probably be high.(13:36) Gaël: Ismael, is this something that you've noticed as well or do you have another angle as a developer?(13:44) Ismael: Both. I definitely agree with absolutely everything that Catalina has said, but I also think that there is a structural issue that is driving a lot of this, and it's the nature of the ICT market in Latin America. I think there are four layers to it. You have the base layer of a very small website and simple apps for a domestic market, that are not necessarily high skill and they're also not high in price. So that means that developers generally do not have much say in terms of what or how they build. They are freelancing. There's a huge gig economy around ICT. So that first layer of the gig economy means that even if you cared about green software, and even if you were a bit informed about green software, the opportunities to present it, to incorporate it, to discuss it, are smaller. Then you have the next layer, which is where you have developers who are building more sophisticated software applications, and are who are primarily competing on price - they tend to be software agencies, and this is another scenario where they are given not a lot of resources, not a lot of time to come up with an app and who do not necessarily have a high level of training or focus on quality. The importance is to churn out products and the jobs are precarious. So, the long-term thinking around green quality, around impact, around all kinds of things that companies might do if they're building a single product over three or four or five years is much harder to do if you've got a three-month contract or a five-month contract.(16:12.) Gaël: There is, in different parts of Latin America, a much more highly skilled digital labor force and people are offshoring to Latin America and often for longer-term projects. So often, in major companies, people will have products that they're building and they will have entire teams based in Mexico or in Colombia or in other parts of Latin America. And there you will have the level of expertise required to build perhaps green apps, but the commissioning process, the people making the actual decisions on architecture, on design, on hiring, are all in the United States, in Canada, in Europe, and they don't particularly care about the environment.So, they are achieving high quality for lower price. And then the final layer is the unicorns. You have some Latin American tech companies that have begun to emerge in Mexico. I can't remember the number, there might be five or ten unicorns. So, these are people getting billions from venture capitalists etc., and they are no more green than any of the big companies in the global North. So, whereas I think there is a big gap between awareness in Latin America and awareness in North America and Europe, I don't think the gap in practice is equally as large, because in Europe and in North America, people really are much more aware of the environmental implications of software, but I don't think they are particularly more committed or active in building greener software. So, the same people who are building the most polluting software on a global scale across Europe and North America are the people who are hiring the Developers in Latin America to build that software. So, there's a whole bunch of structural factors that, even if you have the desire to build green, would create significant barriers. These are significant barriers, because you have less power.as an external freelancing or contracting Dev than if you are a staff engineer in Google, for example, to say, actually, ‘I want to do it green’. So even if you have the awareness and the resources, I think there are economics and responsibilities that lie outside of Latin America for some of the barriers that we have in implementing green applications.(19:30) Gaël: Ismael that's super insightful to go all the way up to the entire structure of the tech economy in Latin America. So overall, this is not really good news that you have shared because low level of general awareness, lack of documentation in Spanish, lack of green, (or not a single one, actually) structural issues, several about who gives order a short-term profit incentivization. I guess it was you, Ismael, who also mentioned that there is a terrible lack of political pressure concerning these topics. So, it’s pretty hard to try to code green or to design green in Latin America.Yet still, here you are, like thousands of others. So, I'd like to switch the narrative a bit here, and to see the glass as half full or even one third or one quarter full, and say, okay, so I'm just a tech worker in Latin America, what can I leverage to help me build a greener internet? And how vibrant is the green IT ecosystem in Latin America? Because maybe it's not as vibrant as other parts of the world, but I know for sure that there are people working on these topics. What are the available resources? We say that there are not many, but I guess we still have some resources. What network should I connect with? So, Catalina, would you like to give some advice to someone starting in the design or the sustainable design business? What would you say to this person? (21:07) Catalina: There are some resources available such as blogs, discussion groups and online communities. The offer in Spanish, like those in Portuguese, is not the same as that compared to languages such as English or German. But I think that digital sustainability today in Latin America is an issue only for large worldwide private companies, such as Google, Apple, Facebook, Amazon, Microsoft or other large companies in the country / region, for example, Globant, Nubank, Rappi, Natura, Mercado Libre. But it is noticed as subject now by small entrepreneurs or micro entrepreneurs or designers or developers. We have to start talking about digital sobriety and the impact of digital actions by ordinary citizens can contribute. Not only how the companies we consume can neutralize carbon emission, but also how we, the user, can support and contribute. (22.15) Gaël: Ismael, from a developer's perspective, what would be the resources and the approaches that you would advocate? (23.23) Ismael: I'd like to mention three things and not just as a developer, but also for entrepreneurs. And I think we need to make and understand that green software is not a barrier or a hurdle to get over, but it's also a commercial opportunity. So, for example, across Latin America, there is, in Mexico, I think there's something like 71 million regular internet users, but there's a huge percentage of people who have very low intermittent access to the internet. In other parts of Latin America, the number of people with poor connectivity is even greater. If you're able to design an app that is green, you are likely to design an app that works well under low connectivity; that uses less data, so it is cheaper to run. And you are likely to design an app that is flexible, depending on availability, which means that you've got a gigantic addressable market that does not exist in the global north. So, the first thing I would say is that entrepreneurs, companies, inventors in Latin America should think about that large addressable market that could be reached if you build software with green patterns. And the nice thing about green software is that you end up building an app that works both for the person in that village that has full connectivity, and for the businessman in the city, and for the woman president in that country. And they can all use the same app because you developed it ‘green’.The second thing that I would mention is that regulation is coming. It's already started. Europe as ever is ahead. France is ahead of Europe. The US is beginning to catch up. And this means that a lot of the nearshoring jobs that will come to us in Latin America, a lot of the companies in the US and in the EU who will hire Latin American debts, will in the next three to five years, have to demonstrate that they are reducing emissions in the apps they build. So that means that if you're a developer or a student right now, and you master the art of green software, you're going to be at the cutting edge of labor demand when there is a huge skills gap. And when people are coming to Mexico or to Colombia and saying, ‘we want to hire devs but in order to comply with regulation, it needs to be built green’, it you've started learning now, you're going to be in a uniquely competitive space. And the last thing that I want to mention is community. Community really matters. Go check the software community that Catalina mentioned. Climateaction.tech has a bit of a Latin American bit growing.But I also wanted to say to any listener that the Adora Foundation is going to launch a project to bring green computing knowledge onto Wikipedia in Spanish. And there are grants for this. So, if anybody wants to partner with us in creating what they call Wikathons, I think, but basically, partnering with us in creating new and translating existing green compute content into Wikipedia, please reach out to me on LinkedIn, and we will add you into the partnership. And together we can create a massive explosion of access to knowledge in the most democratic platform available in Spanish and eventually in Portuguese and other languages too, but we'll be starting in Spanish. (26.33) Gaël: And just to bounce back on what you've said, Ismael, actually there is another tool which is now available in Spanish - the Digital Collage:-(26.47) Ismael: El mural digital.(26.33) Gaël: Yes. Ismail, you mentioned communities, and I know that Catalina, in previous discussions, you mentioned the importance of the open-source community as one of the solutions, because we're still trying to answer this question: ‘Where can I start when I am a developer or a designer or an entrepreneur in the tech sector in Latin America?’. Do you want to elaborate on the importance of the open-source community?(27.25) Catalina: Yeah, the open community in Latin America is very big and robust and very active. The focus is the collaboration and open access and quality software. Maybe the privacy and data security is a central topic. But it's important that I mention that in Medellín, my city, because Medellín won the recognition of the most innovative city in the world in 2018, and the most intelligent city in the country in 2022. And is known as, or is calling to be known as, the software valley. Here, there is enough scholarship to bring people closer to technology. And we are rich human talent in all digital issues, and we are in the place that has the most technology communities within the country, or maybe the region. But the question is we never hear about sustainable web design, green software or digital sobriety, that there is only focus on programming language, databases, artificial intelligence, security, marketing frameworks, libraries, apps, etc. And my question is why? Digital technologies are responsible for the 4% of all greenhouse gas emissions of the planet, and that the cloud has a larger carbon footprint than the aviation industry. That 10 hours of high-quality video contain more data than all the Wikipedia articles in text format. That the web and the data centers that power our digital lives consume more energy and water that we can imagine. And it's controversial, because it's a city that has many technology communities, but it never speaks about this topic, this ‘sustainable digital’ and it's a question for me every time, every day. (29:56) Ismael: I think that's a really great point, Catalina, a really important one. I have also found that I know many Mexican developers who are in the very top rank of open-source contributors to their projects, people who have contributed to the Linux kernel or people who are at the heart of WordPress, or at the heart of all kinds of big open-source projects with really serious international contributions and recognition. And I think that would be a fantastic population to target. And if they are listening to this podcast (and I hope they are), I will certainly be promoting it.I think if you've got a voice in your area of open source, if you are a serious contributor as a Latin American to an open-source project, consider that you may be the person who can green that technology. You may be in a really good place to actually impact on a technology that impacts millions of people because you know what you're doing and you've got reputation and credentials. So, to all the Latin American open-source contributors out there, and especially those of you who are really serious about it, consider asking yourself the technical question: If I wanted to green this open-source project, what would I do? And then rally people around it. You will find all of us around the world supporting your efforts.(31.44) Gaël: Thank you Ismail. That's very inspiring and actually quite true as well, because the momentum we've got today in digital sustainability in Europe, just to speak about what I've experiencing, has been built a lot on the open-source community, and with people just, as you said, starting to pay attention, usually coming from privacy movements, the question of truly open source, and the intellectual property issues around digital rights, etc. And suddenly they are switching to, ‘oh, but actually there is a missing part in my puzzle, which is sustainability’.And connecting to the question of having different angles, there is one last question I wanted to ask to both of you. Going a bit beyond this green angle that we had, how much can we, or shouldn't we, disconnect the environment from other issues like ethics or social justice in Latin America? Because we were discussing before the interview that some, especially some countries in Latin America, are rife with inequalities and that might be hard, actually, to dissociate both, or should we dissociate both because otherwise no topics get any traction if we try to connect too many things. What are your opinions on it?(33.17) Catalina: Okay, I believe that we cannot disconnect and separate these issues, because everything in the planet is systemic. The environment, ethics and social justice are interconnected in systems that depend on each other and together they form a complete vision of a better and brighter world for all. Social justice means that everyone must have equal access to resources and opportunities, and that basic human rights must be protected. And the ethics is about doing the right thing and treating our natural environment and other forms of life with respect. We must act responsibly to preserve the herd, not just for ourselves, but for others as well. Our ethics is how we treat the herd and others life forms, it has a direct impact on social justice for generations. But I think that it's impossible to disconnect and separate these issues.(34:33) Ismael: Thank you, Catalina, for your point about ethics. Actually, you're not going to green software if you do not have values that drive you towards it, right? It is a values-based choice. So, you cannot associate values from that decision. I would question, however, the framing, Gael, that you introduced, because you pointed out the inequalities within Latin America. And I think the inequalities within Latin America are a huge, huge dimension of this. If you do not have access to water, let alone to internet, let alone to full literacy, then clearly your ability to contribute to – though I guess you are contributing to a greener digital footprint by not using it - but you will be limited in those abilities and those skills if your access to information is limited. Then even if you are educated and keen, it's going to be hard for you to acquire it.However, the real constraint on greening the digital world in Latin America, from mining through to the supply chain, through software building, is not the inequalities within Latin America, it's the inequalities between Latin America and the rest of the world. It is the dynamics of the way Europe, and in particular the United States and Canada and China and the richer countries, interact and consume Latin American resources and products, that are the biggest determinant of the kind of applications that get built. So, the challenge of justice here is that it is definitely crucial to have justice within Latin America. But one of the reasons why you don't have regulation that works, is because of pressure from companies that are not based in Latin America. So, I would say the social justice issues are the sine qua non, the basis of achieving digital sustainability in Latin America. But that involves the inequalities between the people who commission most of the digital products in Latin America, which is the global north, and the people who produce them in the global south. That inequality, I think, is the key barrier. If you can make all of the companies that commission software or mining or supplies or sell e-waste to Latin America from abroad, demand green standards, you will see that digital sustainability accelerates dramatically. And without that, all the goodwill, all the conviction, all the dedication of people like ourselves in Latin America will not achieve a systemic impact. So, yes to the inequalities, but I would say it's the global ones that count more than the regional ones at this stage.(38.10) Catalina: Yeah, I totally agree Ismael’s whole answer. (38:17) Gaël: Yes, thanks Ismael, fair point. It's also definitely an issue about inequalities across the world, and not just within a country or a continent. Now being mindful of time, do you want to add just one more recommendation to learn more on digital sustainability if you're based in Latin America? (38.44) Catalina: I would recommend the talks by Elena Morettini, who is the Global Head of Sustainable Business at Globant, and shares a lot of values, content about transition and energy efficiency and green IT for business/(39.00) Gaël: And what would be your pick, Ismael?(39.04) Ismael: Well, I am conflicted, because I'm going to recommend something that I want to discourage at the same time. So, I'm going to say why I don't want you to use it. I don't want you to use ChatGTP and Bard and LLMs because they are environmentally 10 times worse than most other alternatives. However, what I will say is, if the main barrier right now is information, if you are in Latin America, and if you're listening to this, you probably have enough fluency so that's not your barrier. But you will have so many colleagues for whom this might be a barrier. And what I would advise is, search and google all the resources, all the names that Catalina mentioned, and they are connected. So, the moment you find one, if you find Jerry McGovern, if you find Wholegrain Digital, if you find the people in this very podcast, if you find who Gaël has interviewed, look them up, basically go find all the resources you can in English and translate them. If you can use Google Translate first, it'll be cheaper environmentally. But if not, to be honest, that is a trade-off that I am happy to do. If using ChatGPT or Bard will equip you to green the next 300 apps that you build the rest of your life, go and use it.(40:52) Gaël: Excellent. I didn't expect such an answer. But that's a very nice one. That's a beautifully played card. I'm not going to choose, actually, I'm going to list all these great resources, but the tool is translation. And I fully agree with you, Ismail. Sometimes you use a terrible tool in the right way and that’s the worth the type of investment. But that was great. And so, because we are on a positive mood, Ismail, if you had to share one piece of good news which made you optimistic recently about our path toward a more sustainable world, what would it be?(41.37) Ismael: I need to say that good news is there if you look for it. Around COP27, there were these series of reports that came out, that were dire. They were terrible, they really were. The situation is absolutely horrific. We're moving too slow. But buried in all of those reports, were extraordinary achievements that no one really reported. So, I was in Paris for COP 21. And I remember that at the start of COP 21, the level of ambition was on the floor. None of us believed this was going to lead anywhere, not the governments, not the activists, not the NGOs, not the academics, nobody. And then civil society moved. The largest demonstrations in the history of the planet and the use of technology, groups like Avaaz creating mobilizations. And in real time, I saw governments change their positions. And then when people weren't going to embrace certain targets, city mayors embraced those targets. Terrible multinationals embraced targets, and the mood changed. Now, at that point, the status quo, the business-as-usual scenario, was leading us into the worst apocalypse. The latest reports that came out are saying that we are on track for catastrophe, but we have moved away from apocalypse. No one has tracked the fact that at the most dysfunctional time in global decision-making, humanity has managed to shift track. For the first time in the whole of our records, by 2030, the IEA expects emissions to no longer grow, but to flatline. None of this is enough to spare us from catastrophe. But it shows, that as a global community, we have the power to truly change scenarios. So, we need to understand that power, not become complacent, and go, ‘it's all okay’, but also not to forget that hope exists empirically.(44:15) Gaël: Thanks a lot Ismael. I may just comment on COP21 that, yes, civil society played a big role, but hey, this is the episode on Latin America, so I guess we also have to give a big kudos to one of my longtime heroes now, which is Cristiana Figueres, obviously, because if she hadn't have been there, leading the UN climate delegation, with her amazing ambassador skills, and everything else that she built around her, and the team she brought, etc., I don't believe anything would have been achieved (without downplaying the massive role civil society played too). I'm not trying to give her a percentage here, but just acknowledging that, yes, I think without her, we would be in real dire straits at the moment.(45.08) Gaël: What about you, Catalina? Is there one piece of good news that you'd like to share? (45.14) Catalina: Concerning this point, I need to talk about WordPress. This is my community, right, and some excellent recent news is that the global WordPress community has formed a sustainability group. With 264 members showing a growing interest in the topic though only from Latin America, like Ismael and me, but this is an important step for other people, other humans, whether Spain or other countries in Europe. But it's also encouraging to see that several developers are reducing the size of their plugins to make them more efficient and environmentally friendly. Awareness about the importance of greening servers is increasing, where every small contribution, like removing a single kilobyte, or millions of websites, can significantly reduce carbon emission. Also, it's inspiring to see more people engage in creating a more sustainable web. That is a good piece of news, and good for the global community for WordPress, because it's a good step. (46:44) Gaël: Thanks a lot, both of you, for sharing such positive news at the end, and for the amazing work that you're doing in Latin America, and way beyond just a green internet, to make people aware of the environmental footprint of our digital world. Thanks too for being there, and connecting with me on being based on a very different time zone, and for accommodating all those differences. So, thanks a lot. It was great having both of you. I hope this episode will be very useful for people based in this beautiful region of the world. And as usual, I will put all the references in the show notes. Thanks a lot for being there, both of you.(47.35) Ismael: Thank you. Great opportunity and great to chat with both of you, Catalina and Gaël. Really great opportunity. Thank you.(47.44) Catalina: Thank you, Gaël. Thank you, Ismael. Really, really, I'm very, very happy to share.(47.51) Gaël: Thank you for listening to this Green IO episode. In episode 27, we will talk about all the tools provided by the Green Software Foundation to decarbonize software. There are quite a few, and Nassim Hussain, the Executive Director of Green Software himself, will give us a guided tour. And he might also share some exclusive announcements before the big Decarb Software 2023 conference. So stay tuned.Before you leave, a small message from our sponsor. No, I'm still kidding.

We are delighted to help you, the responsible technologists, scattered all over the world, build a greener digital world….one byte at a time.Transcript (in Spanish - AI generated)(00:09) Gaël: Hola a todos, bienvenidos a Green IO, el podcast para tecnólogos responsables que construyen un mundo digital más verde, byte a byte. En Green IO, exploramos cómo reducir el impacto ambiental de nuestro mundo digital. Nuestros invitados de todo el mundo comparten ideas, herramientas y enfoques alternativos que permiten a las personas dentro del sector tecnológico, y más allá, impulsar la sostenibilidad digital. Más de 300 millones de usuarios digitales, hogar de docenas de unicornios, con escenas tecnológicas vibrantes repartidas por la región. 2.2 millones trabajando en el sector tecnológico, de internet y comunicación, según LinkedIn. No, no estoy hablando de Europa, sino de América Latina. América Latina, un jugador significativo en nuestro mundo digital y, como tal, un contribuyente significativo a sus impactos ambientales. Solo siguiendo un enfoque no riguroso basado en el número de sus usuarios, pero recuerden que la mayoría de los impactos ambientales provienen de la fabricación y el uso de dispositivos y el consumo de electricidad de estos dispositivos. Resumiendo mi análisis rápido, con el 5.5% de los usuarios mundiales, la huella de carbono de América Latina por sus actividades digitales sería alrededor de 77 millones de toneladas de CO2 (2019), lo que es más que cualquier país en América Central, excepto México, obviamente, y, por ejemplo, es más de lo que ha emitido Uruguay. Así que supongo que ahora han entendido que el episodio de hoy trata sobre América Latina, y más específicamente, cómo alguien que trabaja en el sector digital y está basado en América Latina puede contribuir a descarbonizar Internet. Para ayudarnos a encontrar las respuestas, me complace dar la bienvenida a dos invitados hoy. Catalina Zapata, que está basada en Medellín, Colombia. Catalina es una experimentada diseñadora web que inició un proyecto llamado La Web Verde, (mi pronunciación es terrible porque es en español) con el objetivo de democratizar la sostenibilidad en la web, enseñar a diseñadores y desarrolladores cómo crear proyectos digitales más sostenibles y, más específicamente, difundir la conciencia verde sobre nuestra huella digital dentro de la comunidad de WordPress.(02:34.39) Gaël: Descubrí a Catalina en este vibrante grupo de sostenibilidad de WordPress el año pasado, y cuando me puse en contacto con ella, me dijo que ya era una oyente regular del podcast. Y cuando le pregunté por qué estaba tan interesada en la sostenibilidad, tuvo una respuesta muy directa: porque respiramos el mismo aire y todos estamos en el mismo planeta. Y eso fue bastante directo. Bueno, luego, de hecho, me dijo que hace tres años leyó un artículo sobre Internet siendo el cuarto país más contaminante del mundo, y eso fue como un momento 'ja-ja'. Pero en realidad, creo que incluso me gusta más su primera respuesta. Ismael Velasco está basado en México y lo conocí a través de la increíble comunidad CAT. Ismael es un veterano de la industria del software en general, y del software verde en particular. Su concepto de 'degradación grácil' de API me atrajo de inmediato, pero descubrí a alguien cuyo conocimiento y compromiso van mucho más allá de la tecnología verde, con su participación en la Fundación Adora, que impulsa la innovación social en todo el mundo, y su reciente decisión de centrarse más en el lado sostenible de la tecnología. Así que, bienvenida Catalina, bienvenido Ismael. Muchas gracias por unirse a Green IO hoy. (04:02) Ismael: Es genial estar aquí. Genial estar contigo. (04:05) Catalina: Gracias, Gael, por conectar, por invitar y crear este espacio, que no solo es innovador, sino que también es muy, muy, muy necesario para aquellos que diseñan la web y consumen Internet. (04:18) Gaël: Wow, muchas gracias a ambos. Me encantaría comenzar, de hecho, con una pregunta muy directa. ¿El título de este episodio está completamente equivocado? Quiero decir, ¿América Latina es un ámbito pertinente para abordar la tecnología y la sostenibilidad? Ismael, ¿tienes una opinión al respecto? (04:40) Ismael: Creo, personalmente, que sí, es una categoría significativa. Creo que la distribución de la tecnología y el papel y contribución de la tecnología divergen regionalmente. Cada país, cada área tendrá perfiles diferentes. Pero creo que las realidades principales que enfrenta América Latina en relación con la tecnología tienen muchos paralelos. Creo que culturalmente, hay probablemente aún más similitud en toda América Latina que en Europa, en muchas áreas. Las tensiones que experimentamos a menudo también se reflejan en otros países. Entonces, creo que definitivamente es una categoría significativa, lo que no significa que sea homogénea. Creo que encontrarás una enorme diversidad de país a país. Pero no creo que eso niegue el hecho de que abordar la realidad de la tecnología a nivel latinoamericano tenga sentido en muchos niveles. Así que sí. (05:45) Gaël: Catalina, ¿tienes una opinión al respecto? (05:48) Catalina: Creo que en Europa, la sostenibilidad digital se ha convertido en una prioridad tanto para el gobierno como para los negocios. Pero hay regulaciones estrictas sobre la eficiencia energética de los centros de datos, el reciclaje de dispositivos electrónicos y la reducción de las emisiones de carbono en el sector tecnológico. Estados Unidos no ha alcanzado los estándares europeos, pero hay una creciente conciencia de la reducción de la huella de carbono. Pero en América Latina, tenemos un gran desafío para acceder a recursos y conocimientos, y el acceso a la información en español es limitado. Es necesario traducir y adaptar recursos al español y a otros idiomas nativos del continente, para que la información sea más accesible y utilizable. Sin embargo, creo que tenemos un gran potencial, pero se necesita más conciencia y educación de todos nosotros que creamos la web y consumimos Internet. (06:57) Gaël: Bueno, ese es un comentario muy interesante, Catalina, y hay muchas cosas diferentes que desempacar aquí. Así que volveremos a ellos punto por punto, pero me gustaría volver a lo que acabas de decir sobre el nivel de conciencia en todo el mundo. ¿Cuál es el nivel de conciencia según tú sobre la sostenibilidad digital en América Latina? (07:19) Catalina: Para mí, es muy, muy, muy bajo. La sostenibilidad digital es un concepto extraño en Colombia y América Latina. Todos hablan sobre cambio climático, cero neto, economía circular, objetivos de desarrollo sostenible, moda sostenible, derechos humanos, movilidad verde, reciclaje, inclusión, empoderamiento femenino, inteligencia artificial, ecoturismo. Pero nadie habla sobre software verde, web verde o el impacto de Internet en cada una de nuestras acciones digitales en las emisiones de carbono. Y me pregunto por qué. Para darte un ejemplo de lo ignorantes que somos. Soy embajadora del Proyecto Realidad Climática. Es una organización sin fines de lucro, una de las comunidades más grandes de líderes climáticos del mundo creada para promover soluciones al cambio climático. Esta organización tiene una plataforma virtual donde todos pueden conectarse con otros líderes. Hay materiales, videos, foros, eventos, recursos, encuestas, discusiones, seminarios, reuniones virtuales, oportunidades laborales. Y durante los últimos tres años, no he encontrado una sola conversación sobre sostenibilidad digital, diseño web sostenible o soberanía digital. El servidor donde se aloja el sitio web y la comunidad digital no es un servidor verde. Eso crea mucha inconsistencia entre lo que se dice y lo que se hace en empresas u organizaciones o agentes de cambio en América Latina. (09:09) Gaël: No es la primera vez que escucho a alguien decir que la sostenibilidad digital per se, no la sostenibilidad en general, porque obviamente hay muchas cosas sucediendo en América Latina, pero la sostenibilidad digital no es un tema candente. Ismael, ¿es algo con lo que estás de acuerdo, especialmente en lo que respecta a la situación en México? (09:29) Ismael: Sí, creo que reconozco esa situación, y creo que es probablemente el caso para casi toda América Latina, con la excepción del sector académico en Brasil. Pero en Brasil, tienes mucha academia que ha estado publicando durante años. Han sido algunos de los primeros pensadores en torno a la informática y la sostenibilidad digital. Pero son la excepción. Y no creo que incluso en Brasil haya expandido fuera de la academia hacia la industria de manera significativa. En México, un poco como escuchamos para Colombia, he organizado varios eventos aquí sobre 'hacer que tu software sea verde'. He dado algunas charlas, etc. Estoy en contacto con muchas comunidades de desarrolladores aquí, en miles. Y creo que cada vez, sin excepción, cuando mencioné el tema, fue la primera vez que alguien recuerda haberse encontrado alguna vez con una charla o un evento dedicado al tema. Pero, como mencionó Catalina, realmente no hay muchos recursos accesibles en español. No hay entidades que estén presionando por ello. No hay una agenda normativa o política al respecto. Y las personas que han pensado en ello tienden a hacerlo de manera aislada. Hemos estado tratando de comenzar a construir comunidades a través de una serie de eventos sobre 'Haz que tu software sea verde'. Lanzamos uno en México. Esperamos, con Catalina, hacer algo así en Colombia también, y también fuera de América Latina. Pero en términos generales, diría que, al igual que Catalina, mi experiencia es que el tema resuena mucho. En el momento en que las personas escuchan al respecto, especialmente los desarrolladores, dicen: 'ah, tiene sentido'. Quiero hacer algo al respecto. Pero casi siempre es la primera vez que lo han pensado. El nivel de conciencia es extremadamente bajo, con la posible excepción de Bitcoin, que tiene una reputación ambiental global tan negativa que ha permeado la conciencia popular. Y la gente puede pensar: 'oh, sí, Bitcoin podría ser perjudicial para el medio ambiente'. Pero fuera de eso, no creo que sea una discusión que esté sucediendo en general. (12:04) Gaël: Entonces, ¿cómo es que nos enfrentamos a tantos problemas? Catalina, mencionaste que la falta de documentación en español era uno de los problemas, pero ¿hay algún otro obstáculo que un diseñador (porque estás más en el lado del diseño) enfrenta para empezar a 'verdear' la web? (12:28) Catalina: Estoy de acuerdo con lo que dijo Ismael, que el problema principal es la conciencia. Sí, muchas empresas y profesionales en América Latina aún no son conscientes de los impactos ambientales de sus actividades en línea. La falta de educación y conciencia sobre la sostenibilidad digital es un desafío clave para aquellos de nosotros que creamos y consumimos contenido en Internet. Otro punto muy importante es la resistencia al cambio. Algunas empresas y profesionales pueden resistirse al cambio, especialmente si creen que adoptar prácticas sostenibles podría aumentar sus costos o requerir esfuerzos adicionales. Otro punto son los desafíos del alojamiento verde. A veces, seleccionar alojamiento ecológico proporcionado por fuentes de(12:28) Catalina: Estoy de acuerdo con lo que dijo Ismael, que el problema principal es la conciencia. Sí, muchas empresas y profesionales en América Latina aún no son conscientes de los impactos ambientales de sus actividades en línea. La falta de educación y conciencia sobre la sostenibilidad digital es un desafío clave para aquellos de nosotros que creamos y consumimos contenido en internet. Otro punto muy importante es la resistencia al cambio. Algunas empresas y profesionales pueden resistirse al cambio, especialmente si creen que adoptar prácticas sostenibles podría aumentar sus costos o requerir esfuerzos adicionales. Otro punto son los desafíos del alojamiento ecológico. A veces, seleccionar alojamiento ecológico proporcionado por fuentes de energía renovable puede ser un desafío, ya que puede haber falta de opciones disponibles en ciertas áreas y los costos pueden ser altos.(13:36) Gaël: Ismael, ¿esto es algo que también has notado o tienes otro enfoque como desarrollador?(13:44) Ismael: Ambos. Estoy totalmente de acuerdo con todo lo que Catalina ha dicho, pero también creo que hay un problema estructural que está impulsando mucho de esto, y es la naturaleza del mercado de las TIC en América Latina. Creo que hay cuatro capas. Tienes la capa base de un sitio web muy pequeño y aplicaciones simples para un mercado nacional, que no son necesariamente de alta habilidad y tampoco son de alto precio. Eso significa que los desarrolladores generalmente no tienen mucho que decir en términos de qué o cómo construyen. Son freelancers. Hay una gran economía gig en torno a las TIC. Así que esa primera capa de la economía gig significa que incluso si te importa el software verde, e incluso si estás un poco informado sobre el software verde, las oportunidades para presentarlo, incorporarlo, discutirlo, son menores. Luego tienes la siguiente capa, donde tienes desarrolladores que están construyendo aplicaciones de software más sofisticadas y que compiten principalmente en precio, tienden a ser agencias de software, y este es otro escenario donde no se les dan muchos recursos, no se les da mucho tiempo para crear una aplicación y que no necesariamente tienen un alto nivel de formación o enfoque en la calidad. La importancia es producir productos y los trabajos son precarios. Así que, pensar a largo plazo en torno a la calidad verde, al impacto, a todas las cosas que las empresas podrían hacer si estuvieran construyendo un solo producto durante tres, cuatro o cinco años, es mucho más difícil de hacer si tienes un contrato de tres meses o cinco meses.(16:12) Gaël: En diferentes partes de América Latina, hay una fuerza laboral digital mucho más calificada y las personas están externalizando a América Latina y a menudo para proyectos a más largo plazo. Entonces, a menudo, en grandes empresas, las personas tendrán productos que están construyendo y tendrán equipos enteros con sede en México, Colombia u otras partes de América Latina. Y allí tendrás el nivel de experiencia necesario para construir quizás aplicaciones verdes, pero el proceso de encargo, las personas que toman las decisiones reales sobre arquitectura, diseño, contratación, están todas en Estados Unidos, Canadá, Europa, y no les importa particularmente el medio ambiente.Así que están logrando alta calidad por un precio más bajo. Y luego la capa final son los unicornios. Tienes algunas empresas tecnológicas latinoamericanas que han comenzado a surgir en México. No puedo recordar el número, puede haber cinco o diez unicornios. Entonces, estas personas están recibiendo miles de millones de dólares de capitalistas de riesgo, etc., y no son más verdes que cualquiera de las grandes empresas en el norte global. Entonces, aunque creo que hay una gran brecha entre la conciencia en América Latina y la conciencia en América del Norte y Europa, no creo que la brecha en la práctica sea igual de grande, porque en Europa y en América del Norte, la gente realmente está mucho más consciente de las implicaciones ambientales del software, pero no creo que estén particularmente más comprometidos o activos en la construcción de software más verde. Entonces, las mismas personas que están construyendo el software más contaminante a nivel mundial en Europa y América del Norte son las personas que están contratando a los desarrolladores en América Latina para construir ese software. Así que hay una serie de factores estructurales que, incluso si tienes el deseo de construir de manera verde, crearían barreras significativas. Estas son barreras significativas, porque tienes menos poder como un freelancer externo o contratista que si eres un ingeniero de planta en Google, por ejemplo, para decir, en realidad, 'quiero hacerlo verde'. Entonces, incluso si tienes la conciencia y los recursos, creo que hay economías y responsabilidades que están fuera de América Latina para algunas de las barreras que tenemos en la implementación de aplicaciones verdes.(19:30) Gaël: Ismael, eso es muy perspicaz para llegar hasta la estructura completa de la economía tecnológica en América Latina. En general, esto no son buenas noticias que has compartido porque hay un bajo nivel de conciencia general, falta de documentación en español, falta de verde (o ni siquiera una, de hecho) problemas estructurales, varios sobre quién da la orden de incentivos de ganancias a corto plazo. Supongo que fuiste tú, Ismael, quien también mencionó que hay una terrible falta de presión política sobre estos temas. Entonces, es bastante difícil intentar programar de manera verde o diseñar de manera verde en América Latina.Sin embargo, aquí estás, como miles de otros. Así que me gustaría cambiar un poco la narrativa aquí, y ver el vaso medio lleno o incluso un tercio o un cuarto lleno, y decir, bueno, soy solo un trabajador tecnológico en América Latina, ¿qué puedo aprovechar para ayudarme a construir un internet más verde? ¿Y qué tan vibrante es el ecosistema de TI verde en América Latina? Porque tal vez no sea tan vibrante como en otras partes del mundo, pero sé con certeza que hay personas trabajando en estos temas. ¿Cuáles son los recursos disponibles? Decimos que no hay muchos, pero creo que aún tenemos algunos recursos. ¿Con qué red debería conectarme? Entonces, Catalina, ¿te gustaría dar algunos consejos a alguien que comienza en el diseño o en el negocio del diseño sostenible? ¿Qué le dirías a esta persona?(21:07) Catalina: Hay algunos recursos disponibles como blogs, grupos de discusión y comunidades en línea. La oferta en español, al igual que en portugués, no es la misma que en comparación con idiomas como inglés o alemán. Pero creo que la sostenibilidad digital hoy en América Latina es un problema solo para grandes empresas privadas a nivel mundial, como Google, Apple, Facebook, Amazon, Microsoft, u otras grandes empresas en el país o región, por ejemplo, Globant, Nubank, Rappi, Natura, Mercado Libre. Pero se está notando como un tema ahora también por pequeños empresarios, microempresarios, diseñadores o desarrolladores. Debemos empezar a hablar sobre la sobriedad digital y cómo las acciones digitales de los ciudadanos comunes pueden contribuir. No solo cómo las empresas que consumimos pueden neutralizar las emisiones de carbono, sino también cómo nosotros, los usuarios, podemos apoyar y contribuir.(22.15) Gaël: Ismael, desde la perspectiva de un desarrollador, ¿cuáles serían los recursos y enfoques que defenderías?(23.23) Ismael: Me gustaría mencionar tres cosas, y no solo como desarrollador, sino también para emprendedores. Y creo que necesitamos entender que el software verde no es una barrera o un obstáculo a superar, sino también una oportunidad comercial. Por ejemplo, en toda América Latina, en México hay algo así como 71 millones de usuarios regulares de Internet, pero hay un gran porcentaje de personas con acceso intermitente muy bajo a Internet. En otras partes de América Latina, el número de personas con una conectividad deficiente es aún mayor. Si puedes diseñar una aplicación que sea verde, es probable que diseñes una aplicación que funcione bien con una baja conectividad; que use menos datos, por lo que es más barata de operar. Y es probable que diseñes una aplicación que sea flexible, dependiendo de la disponibilidad, lo que significa que tienes un mercado direccionable gigantesco que no existe en el norte global. Entonces, lo primero que diría es que los emprendedores, empresas e inventores en América Latina deberían pensar en ese gran mercado direccionable que podrían alcanzar si construyen software con patrones verdes. Y lo bueno del software verde es que terminas construyendo una aplicación que funciona tanto para la persona en ese pueblo que tiene conectividad completa, como para el empresario en la ciudad, y para la mujer presidenta en ese país. Y todos pueden usar la misma aplicación porque la desarrollaste 'verde'.La segunda cosa que mencionaría es que la regulación se está acercando. Ya ha comenzado. Europa, como siempre, va por delante. Francia va por delante de Europa. Estados Unidos está empezando a ponerse al día. Y esto significa que muchos de los trabajos de nearshoring que vendrán a nosotros en América Latina, muchas de las empresas en EE. UU. y en la UE que contratarán deudas latinoamericanas, en los próximos tres a cinco años, deberán demostrar que están reduciendo las emisiones en las aplicaciones que construyen. Entonces, eso significa que si eres un desarrollador o un estudiante en este momento, y dominas el arte del software verde, estarás en la vanguardia de la demanda laboral cuando haya una brecha de habilidades enorme. Y cuando la gente venga a México o a Colombia y diga: 'queremos contratar desarrolladores pero para cumplir con la regulación, debe construirse verde', si has comenzado a aprender ahora, estarás en un espacio competitivo único. Y la última cosa que quiero mencionar es la comunidad. La comunidad realmente importa. Ve a revisar la comunidad de software que mencionó Catalina. Climateaction.tech tiene una parte un poco creciente en América Latina.Pero también quiero decir a cualquier oyente que la Fundación Adora va a lanzar un proyecto para llevar el conocimiento de la computación verde a Wikipedia en español. Y hay subvenciones para esto. Así que, si alguien quiere asociarse con nosotros para crear lo que llaman Wikatones, creo, pero básicamente, asociarse con nosotros para crear nuevo contenido y traducir contenido existente de computación verde en Wikipedia, por favor, contáctame en LinkedIn y te agregaremos a la asociación. Y juntos podemos crear una explosión masiva de acceso al conocimiento en la plataforma más democrática disponible en español y eventualmente en portugués y otros idiomas también, pero comenzaremos en español.(26.33) Gaël: Y solo para retomar lo que has dicho, Ismael, de hecho, hay otra herramienta que ahora está disponible en español: el Mural Digital:-(26.47) Ismael: El mural digital.(26.33) Gaël: Sí. Ismael, mencionaste las comunidades, y sé que Catalina, en discusiones anteriores, mencionaste la importancia de la comunidad de código abierto como una de las soluciones, porque aún estamos tratando de responder a esta pregunta: '¿Dónde puedo empezar cuando soy un desarrollador o un diseñador o un emprendedor en el sector tecnológico en América Latina?'. ¿Quieres profundizar en la importancia de la comunidad de código abierto?(27.25) Catalina: Sí, la comunidad abierta en América Latina es muy grande, robusta y muy activa. El enfoque es la colaboración, el acceso abierto y el software de calidad. Tal vez la privacidad y la seguridad de datos son temas centrales. Pero es importante que mencione que en Medellín, mi ciudad, porque Medellín ganó el reconocimiento de la ciudad más innovadora del mundo en 2018, y la ciudad más inteligente del país en 2022. Y se conoce como, o se está llamando a ser conocida como, el valle del software. Aquí, hay suficientes becas para acercar a las personas a la tecnología. Y tenemos un talento humano rico en todos los temas digitales, y estamos en el lugar que tiene la mayoría de las comunidades tecnológicas dentro del país, o tal vez la región. Pero la pregunta es que nunca escuchamos sobre diseño web sostenible, software verde o sobriedad digital, solo hay enfoque en lenguajes de programación, bases de datos, inteligencia artificial, seguridad, marcos de marketing, bibliotecas, aplicaciones, etc. Y mi pregunta es ¿por qué? Las tecnologías digitales son responsables del 4% de todas las emisiones de gases de efecto invernadero del planeta, y la nube tiene una huella de carbono más grande que la industria de la aviación. Que 10 horas de video de alta calidad contienen más datos que todos los artículos de Wikipedia en formato de texto. Que la web y los centros de datos que alimentan nuestras vidas digitales consumen más energía y agua de la que podemos imaginar. Y es controvertido, porque es una ciudad que tiene muchas comunidades tecnológicas, pero nunca habla sobre este tema, este 'digital sostenible', y es una pregunta para mí todos los días.(29:56) Ismael: Creo que es un punto realmente excelente, Catalina, uno muy importante. También he descubierto que conozco a muchos desarrolladores mexicanos que están en la cima de los contribuyentes de código abierto a nivel internacional, personas que han contribuido al kernel de Linux o personas que están en el corazón de WordPress, o en el corazón de todo tipo de grandes proyectos de código abierto con contribuciones y reconocimientos internacionales realmente serios. Y creo que sería una población fantástica a la que apuntar. Y si están escuchando este podcast (y espero que sí), ciertamente lo estaré promoviendo.Creo que si tienes voz en tu área de código abierto, si eres un contribuyente serio como latinoamericano a un proyecto de código abierto, considera que puedes ser la persona que puede 'verdear' esa tecnología. Puedes estar en un lugar realmente bueno para impactar en una tecnología que afecta a millones de personas porque sabes lo que estás haciendo y tienes reputación y credenciales. Así que, a todos los contribuyentes latinoamericanos de código abierto, y especialmente a aquellos de ustedes que son realmente serios al respecto, considérense capaces de preguntarse la pregunta técnica: Si quisiera 'verdear' este proyecto de código abierto, ¿qué haría? Y luego reunan a las personas a su alrededor. Nos encontrarás a todos en todo el mundo apoyando sus esfuerzos.(31.44) Gaël: Gracias, Ismael. Eso es muy inspirador y realmente cierto también, porque el impulso que tenemos hoy en la sostenibilidad digital en Europa, solo para hablar de lo que estoy experimentando, se ha construido en gran medida en la comunidad de código abierto, y con personas que, como dijiste, comienzan a prestar atención, generalmente provienen de movimientos de privacidad, la cuestión de verdaderamente código abierto, y los problemas de propiedad intelectual en torno a los derechos digitales, etc. Y de repente se están cambiando a, 'oh, pero en realidad hay una parte faltante en mi rompecabezas, que es la sostenibilidad'.Y conectando con la pregunta de tener diferentes perspectivas, hay una última pregunta que quería hacerles a ambos. Yendo un poco más allá de este ángulo verde que teníamos, ¿hasta qué punto podemos, o no deberíamos, desconectar el medio ambiente de otros problemas como ética o justicia social en América Latina? Porque estábamos discutiendo antes de la entrevista que algunos, especialmente algunos países en América Latina, están plagados de desigualdades y podría ser difícil, de hecho, disociar ambos, o ¿deberíamos disociar ambos porque de lo contrario ningún tema obtiene tracción si intentamos conectar demasiadas cosas? ¿Cuáles son sus opiniones al respecto?(33.17) Catalina: Vale, creo que no podemos desconectar y separar estos temas, porque todo en el planeta es sistémico. El medio ambiente, la ética y la justicia social están interconectados en sistemas que dependen entre sí y juntos forman una visión completa de un mundo mejor y más brillante para todos. La justicia social significa que todos deben tener acceso igualitario a recursos y oportunidades, y que se deben proteger los derechos humanos básicos. Y la ética trata de hacer lo correcto y tratar nuestro entorno natural y otras formas de vida con respeto. Debemos actuar responsablemente para preservar la manada, no solo para nosotros, sino también para los demás. Nuestra ética es cómo tratamos a la manada y a otras formas de vida, tiene un impacto directo en la justicia social para las generaciones futuras. Pero creo que es imposible desconectar y separar estos problemas.(34:33) Ismael: Gracias, Catalina, por tu punto sobre la ética. En realidad, no vas a adoptar un software verde si no tienes valores que te impulsen hacia eso, ¿verdad? Es una elección basada en valores. Entonces, no puedes asociar valores desde esa decisión. Sin embargo, cuestionaría el enfoque, Gael, que presentaste, porque señalaste las desigualdades dentro de América Latina. Y creo que las desigualdades dentro de América Latina son una dimensión enorme de esto. Si no tienes acceso al agua, y mucho menos a internet, y mucho menos a la plena alfabetización, claramente tu capacidad para contribuir a – aunque supongo que estás contribuyendo a una huella digital más verde al no usarlo - pero estarás limitado en esas habilidades y conocimientos si tu acceso a la información es limitado. Sin embargo, la verdadera limitación para hacer más verde el mundo digital en América Latina, desde la minería hasta la cadena de suministro, pasando por la construcción de software, no son las desigualdades dentro de América Latina, sino las desigualdades entre América Latina y el resto del mundo. Son las dinámicas de cómo Europa, y en particular los Estados Unidos y Canadá, y China y los países más ricos, interactúan y consumen los recursos y productos latinoamericanos, las que determinan en gran medida el tipo de aplicaciones que se construyen. Entonces, el desafío de la justicia aquí es que definitivamente es crucial tener justicia dentro de América Latina. Pero una de las razones por las cuales no tienes regulaciones que funcionen es por la presión de empresas que no están basadas en América Latina. Así que diría que los problemas de justicia social son el sine qua non, la base para lograr la sostenibilidad digital en América Latina. Pero eso implica las desigualdades entre las personas que encargan la mayoría de los productos digitales en América Latina, que es el norte global, y las personas que los producen en el sur global. Esa desigualdad, creo, es la barrera clave. Si puedes hacer que todas las empresas que encargan software o minería o suministros o venden residuos electrónicos a América Latina desde el extranjero exijan estándares verdes, verás que la sostenibilidad digital se acelera dramáticamente. Y sin eso, toda la buena voluntad, toda la convicción, toda la dedicación de personas como nosotros en América Latina no logrará un impacto sistémico. Así que sí a las desigualdades, pero diría que las globales cuentan más que las regionales en esta etapa.(38.10) Catalina: Sí, estoy totalmente de acuerdo con toda la respuesta de Ismael.(38:17) Gaël: Sí, gracias Ismael, punto justo. También es definitivamente un problema de desigualdades en todo el mundo, y no solo dentro de un país o un continente. Ahora, siendo conscientes del tiempo, ¿quieren agregar solo una recomendación más para aprender más sobre la sostenibilidad digital si están basados en América Latina?(38.44) Catalina: Recomendaría las charlas de Elena Morettini, quien es la Jefa Global de Negocios Sostenibles en Globant, y comparte muchos valores, contenido sobre transición y eficiencia energética y tecnología verde para los negocios.(39.00) Gaël: ¿Y cuál sería tu elección, Ismael?(39.04) Ismael: Bueno, estoy en conflicto, porque voy a recomendar algo que quiero desalentar al mismo tiempo. Así que voy a decir por qué no quiero que lo uses. No quiero que uses ChatGPT y Bard y LLMs porque son ambientalmente 10 veces peores que la mayoría de las otras alternativas. Sin embargo, lo que diré es que, si la barrera principal en este momento es la información, si estás en América Latina, y si estás escuchando esto, probablemente tienes suficiente fluidez, por lo que no es tu barrera. Pero tendrás muchos colegas para quienes esto podría ser una barrera. Y lo que aconsejaría es buscar y buscar en Google todos los recursos, todos los nombres que mencionó Catalina, y están conectados. Entonces, en el momento en que encuentres uno, si encuentras a Jerry McGovern, si encuentras a Wholegrain Digital, si encuentras a las personas en este mismo podcast, si encuentras a quienes Gaël ha entrevistado, búscalos, básicamente busca todos los recursos que puedas en inglés y tradúcelos. Si puedes usar Google Translate primero, será más económico ambientalmente. Pero si no, siendo honesto, es un compromiso que estoy dispuesto a hacer. Si usar ChatGPT o Bard te equipará para volver verde las próximas 300 aplicaciones que construyas el resto de tu vida, ve y úsalo.(40:52) Gaël: Excelente. No esperaba una respuesta así. Pero eso es muy bueno. Es una carta jugada de manera hermosa. No voy a elegir, en realidad, voy a listar todos estos excelentes recursos, pero la herramienta es la traducción. Y estoy totalmente de acuerdo contigo, Ismael. A veces, usas una herramienta terrible de la manera correcta y vale la pena la inversión. Pero eso fue genial. Y como estamos de buen humor, Ismael, si tuvieras que compartir una noticia positiva que te haya hecho sentir optimista recientemente sobre nuestro camino hacia un mundo más sostenible, ¿cuál sería?(41.37) Ismael: Necesito decir que hay buenas noticias si las buscas. Alrededor de la COP27, hubo una serie de informes que salieron, que eran desastrosos. Eran terribles, realmente lo eran. La situación es absolutamente horrenda. Nos estamos moviendo demasiado lento. Pero enterradas en todos esos informes, había logros extraordinarios que nadie realmente informó. Así que estuve en París para la COP 21. Y recuerdo que al comienzo de la COP 21, el nivel de ambición estaba en el suelo. Ninguno de nosotros creía que esto iba a llevar a algún lado, no los gobiernos, no los activistas, no las ONG, no los académicos, nadie. Y luego la sociedad civil se movió. Las mayores manifestaciones en la historia del planeta y el uso de la tecnología, grupos como Avaaz creando movilizaciones. Y vi en tiempo real cómo los gobiernos cambiaron sus posiciones. Y cuando la gente no iba a aceptar ciertos objetivos, los alcaldes de las ciudades abrazaron esos objetivos. Terribles multinacionales abrazaron objetivos, y el ánimo cambió. Ahora, en ese momento, el escenario del statu quo, el escenario del negocio como siempre, nos estaba llevando hacia el peor apocalipsis. Los últimos informes que salieron dicen que estamos en camino a la catástrofe, pero nos hemos apartado del apocalipsis. Nadie ha rastreado el hecho de que en el momento más disfuncional en la toma de decisiones globales, la humanidad ha logrado cambiar de rumbo. Por primera vez en todos nuestros registros, para 2030, la AIE espera que las emisiones ya no crezcan, sino que se estabilicen. Nada de esto es suficiente para salvarnos de la catástrofe. Pero muestra que como comunidad global, tenemos el poder de cambiar verdaderamente los escenarios. Entonces, necesitamos entender ese poder, no volvamos a ser complacientes y digamos ‘todo está bien’, pero también no olvidemos que la esperanza existe empíricamente.(44:15) Gaël: Muchas gracias, Ismael. Puedo comentar sobre la COP21 que, sí, la sociedad civil jugó un papel importante, pero oye, este es el episodio sobre América Latina, así que supongo que también debemos felicitar a uno de mis héroes de toda la vida ahora, que es Cristiana Figueres, obviamente, porque si no hubiera estado allí, liderando la delegación climática de la ONU, con sus increíbles habilidades diplomáticas, y todo lo demás que construyó a su alrededor, y el equipo que trajo, etc., no creo que se hubiera logrado nada (sin restar importancia al papel masivo que jugó la sociedad civil también). No estoy tratando de darle un porcentaje aquí, pero solo reconociendo que sí, creo que sin ella, estaríamos en una situación realmente difícil en este momento.(45.08) Gaël: ¿Y tú, Catalina? ¿Hay alguna buena noticia que te gustaría compartir?(45.14) Catalina: En cuanto a este punto, necesito hablar sobre WordPress. Esta es mi comunidad, ¿verdad?, y algunas noticias excelentes recientes son que la comunidad global de WordPress ha formado un grupo de sostenibilidad. Con 264 miembros mostrando un creciente interés en el tema, aunque solo de América Latina, como Ismael y yo, pero este es un paso importante para otras personas, otros humanos, ya sea España u otros países en Europa. Pero también es alentador ver que varios desarrolladores están reduciendo el tamaño de sus complementos para hacerlos más eficientes y respetuosos con el medio ambiente. La conciencia sobre la importancia de volver verdes los servidores está aumentando, donde cada pequeña contribución, como eliminar un solo kilobyte, o millones de sitios web, puede reducir significativamente las emisiones de carbono. Además, es inspirador ver a más personas comprometidas en crear un web más sostenible. Esa es una buena noticia, y buena para la comunidad global de WordPress, porque es un buen paso.(46:44) Gaël: Muchas gracias a ambos por compartir noticias tan positivas al final, y por el increíble trabajo que están haciendo en América Latina, y mucho más allá de simplemente una internet verde, para concientizar sobre la huella ambiental de nuestro mundo digital. Gracias también por estar aquí y conectarse conmigo a pesar de estar en una zona horaria muy diferente, y por adaptarse a todas esas diferencias. Así que gracias mucho. Fue genial tenerlos a ambos. Espero que este episodio sea muy útil para las personas basadas en esta hermosa región del mundo. Y como de costumbre, pondré todas las referencias en las notas del episodio. Gracias mucho por estar aquí, ambos.(47.35) Ismael: Gracias. Gran oportunidad y genial hablar con ambos, Catalina y Gaël. Realmente gran oportunidad. Gracias.(47.44) Catalina: Gracias, Gaël. Gracias, Ismael. Realmente, estoy muy, muy feliz de compartir.(47.51) Gaël: Gracias por escuchar este episodio de Green IO.

#0 - Welcome to Green IO Season 2 by Gaël Duez

Hello everyone, welcome to Green IO the podcast for responsible technologists building a greener digital world, one byte at a time.Why this podcast? What to expect in Season 2? Take a 5 minutes walk-through with our Host Gaël Duez 🎙️❤️ Subscribe, follow, like, ... stay connected the way you want to never miss an episode! TranscriptGaël: Hello everyone, welcome to Green IO the podcast for responsible technologists building a greener digital world, one byte at a time.Our digital world has a tremendous impact on the environment, and its trend makes it even more unsustainable than almost any other industry. To address these issues, we need everyone on deck within the Tech industry and beyond. It’s a challenge compared to other sectors. Take the worldwide road freight for instance, it accounts for roughly 4% of all GHG emissions like digital tech but not all companies operate a truck on their own and not everyone has a small delivery van in their garage. Here's where Green IO comes in. I started my journey as a podcaster a year and a half ago, with a fulfilling 1st season. Together,  you and  I had the pleasure to meet more than 30 guests across 22 episodes. Looking forward to our second season, we’ve sharpened the show’s identity, honing it to 3 key principles. First:“Embracing diversity” With their diversity of gender, of countries, of lines of work, our guests allow us to see the world under multiple angles. And this diversity of angles strengthens our systemic thinking muscle which is crucial to tackle the ongoing environmental crises. Plus, it allows us to be ready to welcome thought provoking conversations like the one I had with Anne Curie - an acclaimed O’Reilly author on Green Software about the futility of code optimisation!Anne: "Write code that is absolutely good for the language that you're writing in. Because compilers do a fantastic job at optimizing your code for you. Don't second guess your compiler."  Gaël:2. The 2nd principle is a bias for action & problem solvingEach episode will focus more and more on a precise problem to solve. This is why I enjoy inviting doers like Drew Engelson - Starbucks’ head of engineering. Drew: “ So I thought, you know, how do I go create my own metrics and, you know, ultimately said, okay, well I'll look at our cost that's directly correlated to the number of resources I'm using or our compute hours and for various services and built like a mapping between those metrics I have easy access to from our cloud dashboards. Apply some algorithm to it and, and come up with a number. Right? And I did that and we created, you know, a chart over time. And in addition to that also thought about building a recommendation engine.”Gaël:3. The 3rd and last principle is “Building bridges” In his podcast “The Great Simplification” Nate Hagan stated that we need more diplomats within the sustainability field to enable people with strong identities (climate change, biodiversity, climate justice, global south, etc.) to discuss with each other and achieve common understanding. I’ve always pictured myself as a bridge builder with a constructive stance. This state of mind is also what I’m looking for with our guests. As illustrated in the 1st episode of season 2 by Harriet Kingaby who remains constructive even when facing greenwashing mistakes!Harriet:" What we often see driving greenwashing is not necessarily organizations sitting down and saying 'How can we mislead consumers' (though we definitely see that). Often you might see an overexcited marketing team who were really proud of something that the organization has done, who actually, (I think, with the best will in the world), spotlight it, ignoring the other stuff that the organization does."Gaël:Focusing on building common understanding allows us to be optimistic, and I remain - like Christiana Figueres - a stubborn optimist. This is also what I’m looking for with guest like Sandy Dänhert talking about sustainable design.Sandy:"This is what it can look like. It's not boring, it's not outdated, it's not just minimalist. It can be minimalistic if it fits the brand - and that's cool as well - but it doesn't have to. It can be vibrant and colorful."Gaël:And following these three key principles, we will target 2 complementary goals in this 2nd season: Training our systemic muscles, andSharpening our green skillsTo train our systemic muscles, we must be curious. We will explore various environmental topics like carbon accounting, electronic waste, impact business model, anthropological studies, greenwashing, and new legal frameworks, to name a few.We will also sharpen our green skills. How we - as responsible technologists - we can reduce the environmental footprint of our activities. We will get the latest tools and hands-on insights on focused topics such as impact measurement, Greener Data science and data engineering, Sustainable Design, Sustainable Product Management, Green Software development, Sustainable Cloud operations, etc.We will have episodes that touch on both goals, and some that focus on just one. But all the while we will achieve our main goal, to make our digital world greener, one byte at a time. Green IO Season Two starts next Tuesday September 5th. I’ll see you there.❤️ Never miss an episode!

Welcome to Green IO the podcast for doers making our digital world greener, one byte at a time. I'm your host, Gaël Duez, and I invite you to meet a wide range of guests working in the tech industry to help you better understand and make sense of its sustainability issues and find inspiration to positively impact the digital world. If you like the podcast, please rate it on Apple, Spotify or your favorite platform to spread the word to more responsible technologists like you. And now enjoy the show.So, Green Software. Quoting my dear friend Ismael Velasco, « Our code is harming the planet » and I am privileged today to have two of the best experts European-wide, and I dare to say, worldwide, to deep dive about it. One is based in London, England and the other in Berlin, Germany. Let's start with Anne Currie. When I think about her, I have this song from Dire Straits, ‘Lady Rider’ in mind, because Anne is a writer indeed of several science fiction novels, as well as the much-anticipated O’Reilly book ‘Building green software’ with her two partners in crime, Sarah Hsu and Sara Bergman. The book is in early release, and I can't wait to discover the animal, which will be finally chosen. Anne and the two Sara(h)’s, with and without the H, are also pillars of the Green Software Foundation, and are carrying the flag for sustainability in tech in many conferences like ‘QCon London’ or ‘Apidays Paris’ (a leading API conference series), just to name a few.When I had the pleasure to meet Arne Tarara, we went for a walk in a small park in Berlin. This is how he likes to exchange, outside, surrounded by nature. And during our talk, I was astonished by Arne's deep knowledge on green computing, and his commitment to build efficient tools for developers in the true open-source spirit through the startup he created called « Green Coding Berlin ». As you can guess, both of them are seasoned software engineers having decades of practice behind them.Hello Arne. Hello Anne. Nice to have you on the show today, and I'm going to be super cautious with the pronunciation of your names today, so that everyone will understand when I ask Anne, and when I ask Arne, to intervene, so as not to confuse too much all our American friends. And I'd like to start with the usual question I ask all my guests, which is: “how did you become interested in sustainability, and in the sustainability of our digital sector in the first place? You know, did you experience a light bulb moment, or was it more like something that was there forever?”. Maybe, Arne, if you want to start?[00:03:20] Arne: Sure. Thank you for the nice introduction. I think the important point is one you already mentioned, that I have already been a software developer for quite a while, 16 plus years or so. I had just finished with my former company, which was mostly in performance, marketing, advertising, online shops etc. So, one of these classical building businesses, I would say, at least at the time, and I wanted to make something that had more meaning to me, and had a more sustainable touch. So, I tried to branch out in different fields. It wasn't clear if it would be digital or not. We have a strong meet-up culture here in Berlin, actually, same as in the US, I guess. And I was introduced to the meet-ups about green coding. People that claim that they can make the world a little bit better, not only the digital sector, in particular by using software. On the one hand, it was a bit surprising that you can be a professional in your domain for 16 plus years, and you obviously know that there's stuff like supercomputer optimizations, and hardware gets better over time, and more efficient. But you didn't even think about this issue in Germany. We have this pro work [attitude], like sweeping in front of your own door, i.e., basically just checking whatever you do, and see if that could be improved, made more efficient in any way. And I was introduced to this meet-up group and I would say, yes, it kind of had this mind-blowing effect on me - it was like « wow ». Actually, there is so much you can do. And this niche opened up to me. I believe green coding is still to a certain extent, [an area] that you can get to know very many people very quickly, people who seem to be the top players, with what they are currently doing at the moment, and that there is so much potential to be lifted, there's so much to be done, so much you can do with software. So much efficiency gains [to be reaped] that are still lying around in software field. And I immediately knew, OK, this is what I would like to do, and I looked around, and there were not many tools at the time. The tools that I discovered which kind of had my idea implemented in part, was, for instance, GreenFrame.io, which is still around. And I think it's actually from France, right? I picked up the tool and I tried to use it, and it didn't work at all for me, and it was not open source. And then I thought, this the natural way I'm going to contribute, but it was not possible. They will not act; they are not interested. I contacted the support team, but didn't get a call back, etc. And I thought, OK, I'm going to re-implement it myself, I made the green metrics tool, which is one of the main tools we're doing and said “OK, I also want do it a bit more professional, and be a business, and want to carry out research in this field ». And this is when I created Green Coding Berlin, and set up a small team of people that we would al like to work with. And now we're doing research and trying to make the sector a bit greener.[00:06:10] Gaël: What about you Anne?[00:06:13] Anne: I've always been very interested in efficiency, and a lot of that comes from the fact that but I've been in the software industry since the early nineties, and back then everything had to be efficient. We didn't really have any choice in that. The machines were really terrible, you know, in many ways, 1000 times worse, 1000 times less bandwidth, 1000 times less power. We had to be incredibly efficient in the way we wrote things. So back in the nineties I worked for a while on the first version of Microsoft Exchange, in these days, with one of my co-authors, Sara Bergman. She [still] works on exchange, you know, nearly 30 years later. It's always been interesting to me, that it’s still effectively the same product. But it requires 1000 times more resources to do its job now than it did then. And when you look at the world and the energy transition that's going to have to happen, you realize that 1000 times more resources, that's a lot. And we could really be doing with using that electricity, those resources, as efficiently as we did in the past, today. Except there are issues with that, you can't just go ahead and do it. That's the tricky thing to be doing at the moment. How do we align them both? So, I wouldn't say I didn't have a kind of an epiphany, a kind of like religious belief that we had to do better. Just the knowledge that we really could (do better). And this is something that has to happen and therefore we will do it. And this is a key way that we will do it, through increased code efficiency. But that's not the only way, but it is a fundamental way.[00:08:02] Gaël: I didn't do any software engineering back in university, that is not what I studied, but I learned everything on the ground with a tremendous mentor called Jean Yves. And he used to tell me already about the old days, you know? And he had this expression, that in the old days we had to break every byte into two. And it started already to be, yes, quite convenient. The computing power was going up. Storage was less and less of an issue, etc. But I could not forget what he used to tell me: you need to pay attention to memory resources. You need to pay attention, and we completely lost sight of it. And it's quite fun to hear you referring to these times where resources were super scarce and super expensive, actually. And that actually leads me to the question I wanted to ask you, and so I might lose my bet, but I would dare to say that if I bet a dollar or a euro or a pound with you, and you choose your currency, that the words ‘green software’ was not that widespread, I guess, when you started coding. So how do you see the evolution (of it) today and, maybe more specifically, during recent years? Where are we? I mean, is it that widespread? Or is it more like do we (Arne, you and I) live in some kind of informational bubble, and we actually think everybody cares? But perhaps that's not the case?[00:09:37] Anne: I think well, I'll answer your first question first, which is ‘No’. 30 years ago, green software did not exist as a concept for two reasons, really. Software just wasn't that much of a hit on the economy at that point it, it didn't use that much electricity, the software industry wasn't that big. It didn't have the impacts that it does today. Plus, also, you know, culturally, we weren't thinking about these kinds of things back then. But ironically that the kind of things that you have to do, or are part of being efficient and using energy well, for software we were just doing it, because we had to, because we had those terrible machines. So, in some ways, we were great, because we were doing a lot of the right things, though not all the right things, but we were doing a lot of the right things. We had efficiency absolutely down to pat. But that was because it was necessity rather than because we actually had to do it. But these days, I think you're right in saying that there's a risk that we're all in a bubble, where we think this is something people care about now. But it isn't. But it has become, massively, massively, more top of mind in the past few years. I remember talking about this at conferences 5-6 years ago, and people looked at you as if you were crazy, and we even got complaints. When we ran tracks on this subject a few years back, people were saying, well, that's politics, it's not technology, it shouldn't be included, in conferences. But now nobody says that. Everybody knows that it has to happen. There has been, I think, the IPCC report that really woke everybody up. And the fact that the tech industry is one of the biggest industries. We have to do things and yes, some of it is going to be efficiency, just like we did in the nineties. And some of it is going to be time-shifting, which is in the long term, even more important.[00:11:35] Gaël: Could we say that the awareness has dramatically raised? But what about the practices? Maybe Arne, you want to comment on this one? Did you really see a significant change in the way people code, even if they are aware of the ecological crisis that we are into at the moment?[00:11:55] Arne: I think part of every business that everybody does (or should do) is to do a bit of research, asking: ‘has this maybe come up before’? Have people been talking about green coding before? Are we currently on a hype or are we currently in some kind of a valley [trough], so to say? And if you look back in the academic world, there were already, in 2007 – 2010, very many papers around green coding. There was the university in Texas who had this Archer supercomputer where you could actually measure all your code and before even RAPL was out there. Or perhaps it was around the same time.  which I think we would come to technologies later. But let’s put it out there for the moment that one measuring technique is the processor itself. You could already do it on systems that were out there. But basically, nobody was interested anymore. And I would say a drought of papers in the academic world happened, and now it's coming up a bit again, at least in Germany. We have a conference about it ‘EnviroInfo’ where it's mostly about computings and ecology in general. So, I would say that the green coding, at least in my historical view when I looked at it, has already had its ups and downs. And now coming back to your particular question, especially, I would say in the last year, I wouldn't say that there is necessarily a stronger move on people adopting these techniques. So, a measurement you could, for instance, take, is one of the most prominent softwares, I guess, like, cloud carbon footprint. And Scaphandre [a metrology agent dedicated to electrical power consumption metrics].I would put out here for instance how many GitHubs do they have over time, is there a search or something? I don't have all the data as I'm not the repository owner, but this is my view on how green coding has evolved over time. But, if it's OK, I will elaborate on this one a bit because you also asked me about what we are doing and how we see the sector in particular. We at Green Coding Berlin do not necessarily do what people often think green coding entails for them in particular. When we talk to companies or young developers, they ask us for optimization. They say, “OK, how can I make my code greener in particular right now? Which tool do I have to use to emit less carbon?”. This is actually something we don't focus on a lot in particular because green coding, as from my view, if you look at the digital sector as a whole, (it) is not a problem that is coming from the industry itself. The industry doesn't necessarily have an issue with the digital product that it's using. It's rather something that's coming from states as actors, from developers, and from consumers. The industry itself, in my view, has an incentive to tackle things that they think are not efficient enough. For instance, the machine learning models, because they cost them a lot of money. I think this will be resolved on its own. A bit of additional pressure might be nice, but it's not necessarily needed, I guess, for this to transition. Or things that are not cost effective, so, if you look at something like YouTube, Twitch and Bitcoin, they are in themselves, for the most part of it, already cost effective. But people complain about them a lot and think ‘can we not make this greener in a way?’, because they often don't use these technologies themselves. You will rarely hear complaints from people that earn their money with Bitcoin, that Bitcoin should be should use less energy. And generally speaking, people that don't use Twitch are more likely to complain that one such streamer can emit x amounts of carbon. But for the companies that run them, like Google, that runs YouTube, or Twitch which I think is owned by Amazon, it's a cost-effective thing for them to use these platforms, even though they will produce an enormous amount of data, which is harmful on its own. But it works for them. The incentive is there, but it’s not that intense. And I think green coding techniques on YouTube will take a while until they're implemented if they are not directly cost effective, for instance. On the flip side, the developers are becoming more concerned. This is what we see, for instance, as a company. But this overlap of business and interest, I think this is still in the making, and I'm not really sure if this is the biggest driver. So, I think that green coding, and the effect (coming back to your question in particular), will mostly happen. And this is also what we work on at “Green Coding Berlin”, in particular through regulations. And this means that you have to have the transparency first. And this is what our tools are mostly doing. They are giving developers and users transparency. They make stuff comparable, and then some someone can step in, like regulators or society, to force that optimization techniques, or limits can be implied.[00:16:42] Gaël: And how do you enable more transparency to happen when we have so many issues? And I'm not going to brag or quote too much during this discussion, from Max Schulz from the SDIA. But he's got a point when he says, again and again, that especially the main hyper-scalers are not providing enough comparable and transparent data to truly leverage everything that we could do in computing. Do you also believe that it's an issue? Or actually, what you were saying is that with the tools that you've developed or the approaches that you encourage people to follow, there is a way to become more efficient? Even if some data are missing. And I know that all the hyper-scalers are, I would say, not doing things at the same speed. But I will not enter into this debate here.[00:17:38] Anne: It's interesting with the hyperscalers, they are interesting because you can put pressure on them. Even, obviously, Governments and things could put pressure on them, but it's amazing how much pressure users, customers can put on them. If you say, « Look, I want this, I'm demanding better carbon footprint, measure(s), I'm demanding this information ». They are quite customer, well, I say they are, not, they are. AWS. Amazon is quite customer responsive.  Actually, Azure is quite customer responsive as well. Google not so much, but if you raise this, if enough customers raise it, and it doesn't require that many, and you keep raising it, they (hyper-scalers) will see that there's customer demand for it, and then they will do it. When Amazon talks about being customer obsessed, they actually are. If you keep raising (it), if a handful of people, not that many, just keep raising this, with AWS reps, we have a good chance of getting it. And we got those sustainability commitments. Whether they will be sufficient in the end remains to be seen. But we have made progress by getting folk to raise issues with their providers.[00:18:45] Arne: I think this is one of the big levers to go to, that you have to put the pressure on the cloud providers, either through the user side or through a regulatory side. And, for instance, this is what our tools are trying to do. A lot of people run an extensive amount of CI/CD pipelines, and what our tools do is that they simply create an easy machine learning model that's based on an open database of server energy consumption, called spec power, and then you plug that into a bit of code, so that it can be digestible by GitHub actions. This is their pipeline product. Or by GitLab CI. This is their pipeline product. And then you just see at the end how much your pipeline is consuming, and you see it for your hundreds or thousands of pipelines. And then you have a number, at least at the end of the month, and you can see if this number is going up or going down, and then you can go the route that Anne was suggesting and saying: “Hey, this number is maybe not the best because this company green coding building is doing it from the outside in. So why don't you give us these numbers? “.  So, they go to GitLab and they go to GitHub or Microsoft in particular. And they say, « We want better numbers. It's not so hard for you to give them to us. And now we see that it's possible to actually, somebody can do it from the outside in. So why don't you give us these numbers so we can be better ». But we believe that people need to see this to a certain extent before they can even ask the right questions. [00:20:06] Gaël: It’s a bit like starting with the metrics, we have to create a momentum and then in parallel, put pressure to get better metrics and better data from providers. And if you don't mind, both of you, because we could discuss a lot about cloud providers and the general approach, but actually, I'd like to deep dive a bit more with you. Could you share the top 2 or 3 techniques or approaches that you implement, I would say on, almost on a daily basis, to reduce carbon or carbon emissions caused by software?[00:20:41] Anne: I'm a bit controversial on this one, so I'll start off and say, this is something that came up when we started writing « Building Green Software ». One of the questions that came up immediately from people [was]… “Oh, in the book can you cover some examples of efficient code?”. I used to write efficient code. Almost everybody I know writes efficient code and we all (this is terrible), we all laughed when someone said this, because almost the definition of efficient code is, it's incredibly custom. It is utterly and specifically custom to the very, very particular use case that you're interested in, and a really efficient code takes ages to write. It is incredibly bad for developer productivity, so generally it's quite hard to give people advice about how to write efficient code. I mean, you can say, ‘Well, I'll use efficient languages like C or C++ or Rust, rather than less efficient ones like Python. But even that's not so clear-cut these days, because there are new Python compilers that are compiling Python to machine code, or compiling Python to C. So, you can still write in the inefficient language and have it transformed into a more efficient one, because they know that developer productivity is really killed by writing this very, very highly custom code. So, it's hard to give generic advice. If you speak to folk who are really still writing with efficient code, for example, in the networking area, you're still having to write that high[ly] proficient code, the same kind of code that we used to write 30 years ago because you really, really need that super performance. And their feedback is generally: write code that is absolutely good for the language that you're writing in. Because compilers do a fantastic job at optimizing your code for you. Don't second guess your compiler. Follow best practice so that your compiler can optimize as far as humanly possible. It's a bit sad because everybody wants to hear some amazing, C technique, whatever. But fundamentally, it's just really, really hard and very custom. The best thing you can do is measure different tools. Get somebody else to do it for you. Don't custom write your own high proficient code. Find libraries and tools that are good and use them, which is what you need to use the measurement for. You need to measure to find out which are the good tools in the libraries, and you swap out poor ones for those more optimized ones, but don't attempt to do it yourself unless you are actually writing those libraries, I would say. It's a bit sad, but I would say there's no there's no killer technique that you can use because it's all hyper custom. You know, it's all basically asking around with your L one L, two L, three caches for a very, very specific use case. I don't know if, you might disagree with me Arne?[00:23:43] Arne: No, I actually have the same [outlook], I have the notion that we are very on a par here, with our view on the ‘optimal’, how good these generic optimization tips are. However, if you think about what we often get, [it] is requests from users who see these articles, that Amazon has implemented a new gzip or zlip compression technique in their S3 service and it saved them, I don't know, I think it was in the tens or hundreds of millions, because they had to use less hardware to store their stuff. Or that you see this article that states there is a 70% improvement in React by just stitching the virtual DOM, so apparently it is possible, on a particular product, to get these gains. However, I would very much agree that on a generic level, it's extremely hard to implement. So, there are techniques that have been known for many years, like using vector instructions, loop unrolling, etc., that do work if you really put the work in. But it's a very questionable if really, in the end, if you look at the whole thing. Also, the time the developer had to think in, how much the software will run in the end, how much it cost you building these 50 to 100 iterations until you get it working, if this really saved you something in the final calculation. So, I think this is a bigger question, and I think Gaël you might make a separate podcast on this, this whole idea of software life cycle assessment. This is also something that Max [Schultz] is very passionate about. But I would like to give you our approach on how we typically do it. I think we have the same idea that Anne mentioned, that measuring is like one of the first steps, when we typically consult with companies or when we do workshops with developers. We have these five pillars, so to say, so, first of all, it’s about understanding. People often don't understand the terms that are even used. If you talk about energy and energy efficiency, they don't even know how a network could even cost them in energy terms, that network costs can be linear, or they can be progressive in a way, and then [there is the question of] transparency. The measuring and transparency. Whatever you then have understood and measured, you should also show it to people and make it public. So as in GitHub, as a badge or something. Then continuity is a pillar we focus on a lot, so it doesn't help you if you look at it one time [only], so you have to monitor it over time. So, like the git-ops approach, that with every release, with every build, you basically have to check if your initial measurement or your initial assumptions are still right, or check if the product currently derailing, and you don't want that. Then the fourth pillar is comparing. If you are thinking about software, and you're looking at the goal at the end, the optimization, is to actually sav something, then comparing is often very helpful. So sometimes just looking at how much would database 1 - just technically identical to the database that I'm currently using - how much would this change? So just swapping libraries out, as you said, or swapping infrastructure out is often a better way to go than going on code level optimizations in particular. But they are obviously a point, so our first pillar is then code level optimizations’ wherever they make sense. However, this is then specific, so you have to really look into your product. It often means using specialized tools. So maybe VTune® or something, or code profiling techniques. This is very laborsome, and, these tools are also sometimes cumbersome.[00:27:18] Gaël: I would say it's a lot about measuring and comparing, rather than having one silver bullet, it makes sense. If it was that easy, everyone will do it. And I guess the question of software productivity, the productivity for your developers is absolutely key here. We need to take into consideration the full life cycle, and like you should take three or four times more days, to just release one little piece of code, and so actually, you could even use the energy better.[00:27:53] Anne: Unfortunately, it's more like 10 or 20 or 30 times as long! I remember how long things used to take. They used to take an incredible amount of time. I mean it is interesting, that in the 30 years of my career, there has been more than 1000-fold improvement in machine productivity, and we've used it to make developers more productive. And it's very hard to make the sell to your business that you should go slow, slow down, because otherwise you'll go out of business. So do you have to trade off what you can sell to your business, as well as what is a sensible thing for your business to do, as well as what is the green thing. You have to align them. I'm not saying throw out the green things, I'm thinking you have to find ways to align them both. And the good news is that ((there are)) all the modern ways of working with microservices, with open-source libraries with hyper scalers, hyper-scaler services. Arne said this himself, that there's an alignment, as if you're a big business, to make your stuff efficient because so many people are using it, it is worth putting in that 100 X developer effort to make it efficient because you've got so many people using it, (so) that pays off. But if you're only a small business, and you only have a moderate number of people using your software, you'll probably never pay back that developer effort to make it super-efficient, so you're better off just using a library. Don't do it yourself. Use a library. Use an open-source library, use a hyper-scale service. But I mean, we talked about code efficiency here, but I'm not even sure in the long run that that's going to be the big win that we're going make in the tech industry. I think it's going to be the time-shifting, because even now we're seeing that with renewables, you get huge amounts of energy at some times, and no energy at others. And that requires a whole different way of using electricity. In the old days, it was just, you know, flick of a switch, all fossil fuel driven.[00:30:01] Gaël: Is it something that you implement quite a lot, like chasing the sun, which is time shifting and location shifting, or not that much?[00:30:12] Arne: It is actually a technique we do implement, on workshops, with developers, because it's generally a very interesting technique to implement, as it suggests that there are immediate gains. I don't know if you've recently read the piece, I'm not sure who wrote it, if it was David Mytton or Adrian Cockroft, or maybe I might be mixing stuff up, where there was this piece called « Don't Chase the Sun ». It was like a counter argumentative piece. That [chasing the sun], at the moment at least, often doesn't make sense. I will elaborate on this a bit further, but I would like to say that I generally agree with Anne, that this is an enormous [energy] saving technique, and this is actually what, at least in Germany, we are implementing with the grid. I think every country it does, but I can only really speak for Germany by saying we want to have smart meters. So that in the end, when we have surplus energy, and we really need to not waste it by curtailing it, we want to charge electric cars at this particular time. And in Germany, we have a long way to go by incentivizing people to charge them at these hours so, that it's actually cheaper to wait. Currently, at the moment in Germany, it's not cheaper to wait, even if we would have smart meters, because there is a law that that makes the pricing even throughout the day. But if you look at the current state of how time-shifting works, we are currently implementing a small plug-in for GitHub where you can say, “Hey, I want to run this pipeline at this particular amount of time because the prognosis or the forecast says that there will be green energy at the time”. However, how the grid operators, to my knowledge, typically plan out how the grid is supposed to be, and it is very likely, if you're at some point where the forecast says there is a lot of green energy and the grid is already in a stable state and you demand more, then it will not come from solar or from a wind farm, because this is then already curtailed, because the grid needs this bit planning ahead so they will more likely act, drive the power plant that runs on coal a bit more up. But this is a temporary problem to my understanding, as if they learn these signals over time, so even if you do that 5, 10 times, the grid will learn, then they will actually not curtail the green energy so much, and you will get it. But it's the same as those network savings. It's often not an immediate gain. It's more a theoretical long-term thing until we can understand the signals better.[00:32:36] Gaël: It was Adrian's article, “Don’t chase the sun ». Anne, you wanted to say something, sorry…[00:32:43] Anne: Yes, I totally agree on both the « don't chase the sun ». You don't really want to be moving your data around. What you want to be doing is delaying it, you know, delaying jobs rather than moving data around to chase the sun. I agree with both Arne and Adrian on that one. It's interesting what Arne mentioned earlier: YouTube is an excellent example of one of the products that Google used to do their own kind of grid balancing, on their hardware. That, if you upload a video on YouTube, sometimes it happens. Sometimes you'll notice that it's transcoded very quickly, and sometimes it won't be transcoded for a while. And the reason for that is that they use that as one of their latency-insensitive workloads. If they've got a lot of stuff that's going on, if the systems are busy, they'll just shove that trans coding [down the line], it's a little bit later in the day when things are less busy, so they get better utilization on their machines. And right now, they're working on similar kind of shifting to try and move work to when the sun is shining and when there is potential to power it greenly. But Arne is right, that there isn't necessarily an immediate benefit to that, because right now, the grids might not have enough green energy to provide because that they may already be curtailing it. But in the long run, if you create demand at times when there is potential solar or wind to match it, then more solar and wind will be put in [to the grid] So it's not necessarily an instant win, but right now it's all about the transition. It's about moving to how we're going to work in that new world.[00:34:36] Gaël: I don't remember if he mentioned also this aspect in his article. But it's also that chasing the sun is actually an issue once you start implementing multi-criteria approach, because carbon is one thing, but water is another. And, you know, if you shift all the workloads in a country where you've got plenty of sun, usually water is pretty scarce. And we are experiencing several droughts here in Europe, and the same goes in the US. So, the moment you say OK, let's chase the sun for green electricity, you might also create a lot of problems when it comes to water stress. So that's also why I kind of like his expression don't chase the sun. Maybe ‘Chase the wind’ is a is a bit more accurate, but eventually I guess it's all about reducing the energy intensity, and don't go for a silver bullet or a quick fix that actually does not exist in this energy transition. That's how I understood his main message, and I could not agree more with both of you. If you're OK with it, because we talked a lot about measuring metrics, etc., so could you maybe share a bit, both of you, the do’s and don't’s when you measure, and maybe one or two examples on how you manage to measure for some of your clients.[00:35:46] Arne: What I see in particular is that people have very often very different setups which, I think is normal if people are trying to find ways how to measure things and there is no standard out there. I think you can separate it into two basic domains. There is a cloud at the moment whereby most of the measurement techniques are not available that we use. The cloud is typically more an estimation game. You have premeasured machines and I will come to in a bit how you do that. So, you have, basically, premeasured machines. You have something you could call a calibration curve if you want, I know it's not technically correct, but for some people, this term might mean something. But you basically have a curve that tells you at this amount of utilization, this machine uses this amount of energy, and this curve is typically nonlinear, which requires a bit more than just a simple M times X plus B. So already getting into the technical stuff, so [there is] more than a linear equation to solve this problem, so you need a bit more. So here an easy machine learning model is what we use, for instance, to get this curve, and then you can go into the cloud where at least the utilization, which is a typical Dev ops metric, or a typical monitoring metric that is usually available in many of the products, is what you can use. And you can, to a certain degree, assume that the configuration of the machine that you have already measured is very similar to the machine that's in the cloud, as this database, where we get the data from, are typically machines that are bought by cloud vendors and they often use standard configurations (not all, but some). And then you can get a reasonable estimate of how much a machine in the cloud would use in terms of energy. There's also a similar approach that cloud carbon footprint follows. They have a linear assumption, to my knowledge, but I haven't monitored it currently.  We have this nonlinear one, which is supposed to be a bit better, and I know there are people out there who have even better models, but they are not open source. So how do you even measure it? Most of the academic papers show that people attach a power meter to the computer, which is something that everybody who has done home automation or who just wants to know how much [energy]  a microwave is really using knows, so it's basically an adapter that you can put over your power plug, and it will tell you how much the machine that is connected to it is currently using in terms of watts or kilowatt hours, if you want to have more an idea of energy and not a current power draw.  And they have also USB XS’s, they have Bluetooth’s so you can easily hook them up in a connected system that can also then run measurement drops for people. But for some people, (it is still new for developers, because it's kind of under the hood), there is a technique that is called Intel RAPL or more like a hardware feature, I would say, not a technique. It is something like a power meter inside of the CPU, it is still more of an estimation calculation, but it's very accurate. So very many papers have already confirmed that it's very accurate to their falsification standards & parameters. What it basically gives you, as a developer, is you can write Linux code, and there is a function you can trigger, or a hook, and then you will get the energy that the CPU is using. So, you basically say “Hey, I'm going to start here, and so you make a start point, then you run a bit of code, and then you ask it again, and then you get number B. Then you have number A and number B and you subtract them, and then you know how much energy has been used between these two points. And what we do for measurement in particular is that we ride around these frameworks that already exist, so [there are] external power meters on board, there are sensors that exist. There are also techniques like IPMI which are also internal power meters. So there is this RAPL stuff, and we glue them together in one big open source tool, the green metrics tool, we call it sensor, that can attach these different sensors. And then we give this out as a fully-fledged solution to developers that already have software, which typically is now written in container form, and developers have already set up their container files, something like a doc compose file.  And then they can just say “Hey, please take this Docker compose file, similar to like a bash script or like a Linux Easy, and then I want you to run these lines, maybe run this node program, maybe run the browser » and then you're finished. And I would like you to tell me in between, for example every 100 milliseconds or every 50 milliseconds, I would like you to write down the energy consumed. And then at the end, you get all the energy nicely displayed in the graph. There are some statistics applied to it. [You can ask yourself:] “Has there really been a change from the last time you've tested it to the time you've tested it now ». And to make this even better, we then also offer a service, on the web for free, where we have a measurement cluster with pre-configured machines that apply best practice on how to measure. I can elaborate a bit further on them later, but they do exist. And then you get a better measurement. It doesn't fluctuate as much. It is more reliable. You don't need as many repetitions to get a good statistical, conclusive answer, and see if the code is really different to another piece of code. We try to bring it [the measurement aspect] into a tool so that developers can use it with techniques they already know, like starting and stopping containers, or firing up a tool on the command line. And then they get with the onboard mechanisms that already exist, like Intel RAPL, or using machine learning models through CP utilization. They can then already get a metric out, and so they don't have to be measurement professionals. They just need to know how to use a Linux tool.[00:41:44] Gaël: And this is where you can start comparing, I guess, or challenging the use of this library against another, and all that stuff that you mentioned earlier.[00:41:54] Arne: Yes, exactly. The way to go would be that you have a Docker compose file and then let's say one time you use, as a package manager, you use NPM to install everything, and you want to see if it goes faster or uses less energy. And then you use PNPM, or you use a different one. I think Yard is also a package manager. And you can see if this library or tooling swap will change anything in your build process or your program.[00:42:22] Gaël: Arne, you mentioned best practices. And I know that this is something that is very close to Anne's heart. Could you Anne, maybe tell us a bit more about these best practices, and Arne if you don't mind, you might want to comment on it.[00:42:38] Anne: Well, when I was talking there, the thing that immediately hit me and I thought it quite interesting, is, in the old days, you know it's worth thinking about, the reason why we did all of this stuff was performance. You know, it was like the machines where you had to ring every millisecond of performance you could out of systems. We didn't use to measure energy use, we used to measure performance; your time, how long every operation took. And that's a fairly good proxy for energy use, how long things take, how performant stuff is. But I was thinking about it when Arne was talking, and the trouble with it is, it's very custom if you instrument your code to say, «I assume when this message comes in here, and then this message leaves here, [I know)] how long that is, and if it's less (than previously thought). Because how long things take is often about how many CPU cycles it's gone through. And then how many CPU cycles it goes through is basically how much energy you're using. There's a good correlation between performance and being green, which is why a lot of these kind of highly tuning techniques are still used in networking, where performance is absolutely key; you've got that [indicator]. But the trouble with that is, it's very specific. It's very custom. You have to know what an application is doing. You have to know which messages are going through, and know where to put your instrumentation in. Whereas if you're just measuring the energy use of a whole system, that's more generic. Therefore, you can have tools that are generally more usable by everyone, rather than doing things that are very, very specific and custom. So, I assume that's the reason why we've moved over from using performance as the key kind of way that you measure energy use, to actual energy use, because it is more generic and therefore it's more widely applicable. But would you say that was true?[00:44:48] Arne: Well, I think you're absolutely right in what you're saying. And, if I speak to more seasoned engineers, then they often ask the questions like “Do we really need green coding? » I mean, we have performance optimization. « So where is the knob to tune if I don't take the classical performance techniques? ».  And I think you mentioned some of the green coding techniques already. I think they are unique to green coding, like time-shifting in particular, it doesn't save you any performance, right? It only saves you green energy, or saves you carbon emissions in particular. However, how we see it is similar to how you [Anne] said it. If you think about green coding and energy is now so widely available through many sensors, why not make it the first auto-metric? Because this is actually what you care about, right? You don't want to save on performance at the moment. Or at least this is our mission. If you really want to save on energy, why not take it, even if it's strongly aligned, or if it's strongly co-linear, with performance metrics in particular? When these metrics are not aligning, there is typically something a bit wrong with your code in general. There are energy anomalies, and where you see that, maybe, performance goes up or goes down. But the energy budget goes in a different direction in particular, which could be like mis-configurations, for instance. You could have something like a vector instruction unit in the CPU nowadays called a AVX - It was called MMX or SSE before, to help get some gamers in the loop that might have heard these acronyms. They can be turned on, and then the CPU is using more energy. But actually, it's not doing anything, because it's currently not issuing any of these instructions, and this is typically a mis-configuration. Something turned the unit on, and then it's using more energy, when it's not needed. And so, it could be as though you have your hard drive mis-configured, it's spinning all the time, and so your disk is not going into a sleep mode or a pause mode, where it can stop spinning the disks. You know you are not using the hard drive in particular. This is also where discussions about idle time comes into play. So, your performance metrics could be perfect, but still, the machine is on. So a green coding technique, a classic one, and this also is what our tool shows, that if your code is doing nothing at the moment, does it really have to be on? Maybe it is an architectural decision here, where you say, maybe we move from a super, highly coupled, highly integrated, vertically-only scalable monolith, to something like a micro service architecture that we can actually turn off between requests, because we see more pauses. Then we really see activity, so the node doesn't have to be on all the time. Why not use the energy or the carbon metric as your first order metric? And then, however, if you lay hands on the stuff, [the metrics] you tune the performance metrics, but the measurement that you want to optimize against is the one that is actually following the goal that you want to achieve. Anne: That's a great point.[00:47:49] Gaël: Yeah, I do agree. Especially when we know that we will, more and more, as you mentioned Arne, have to take into consideration embedded carbon and full life cycle carbon etc. And that maybe, at some point, as you say, it will be environmental metrics and not just carbon. Because we have other environmental impacts that we do need to take care of. And this is really a question of which machine shall I use. And sometimes using less powerful machines, older machines, is also a way to save carbon. But that opens a completely different debate.[00:48:25] Anne: It is a different debate, but it is worth reminding that there are three ways that the tech industry has to improve things. It's not just code efficiency. It's not just ‘be energy efficient’. It's also about being hardware efficient because hardware embodies one heck of a lot of carbon. And time-shifting. Those are the three things and we have to do all of them. We can't just do one of them. [00:48:50] Gaël: Yes, I know, recently I was preparing for a conference, and I just found again this amazing interview that Jerry McGovern did with Melvin Vopson. And I know this is a theoretical work, just to raise alarm, but Melvin Vopson estimated the amount of mining that will need to occur to build the server to handle the 25% growth rate in data on a yearly basis that we have today. So, plus 25% data equals that amount [number] of servers to be built just to manage it all. And he discovered that in 2053, humanity will have to mine the equivalent of Mount Everest. So that's 175 billion tons, I think, just to build servers, just to handle the data - we're only talking about the data! And of course, then we can say we will have energy efficiency gains, but the scale is still so amazing, that it is something that we will have to pay attention to in the very near future. I know that at the moment we are focusing a lot on energy and immediate carbon emissions because of the electricity (consumption). But the embedded carbon is the next big battle, and actually it will be, I truly believe, that it will be the main battle at some point.[00:50:23] Anne: Yes, and not just in in data centers. Every time I have to throw away or give away or do something with a working device, like a phone or a laptop, because it's out of support, out of security patch support, but it (still) works!  you know, there's just so much embodied or embedded carbon in that device. It's immoral, basically, for us to know ((that there is so much embedded carbon and)) to give up on providing security patches.[00:50:52] Gaël: Yes, that's true that we need to remember that, those end user devices. They account for three quarters of the entire environmental footprint during the ‘building’ phase, mining, manufacturing, transport, etc. So, of course, as professionals in tech, we focus on what we can do, which is mostly data centers and networks. But that's also true that when you talk with a designer, for instance, they are more and more aware of the tradeoff between “Do I want to enhance my code, even to do green coding, versus, how do I make sure I actually reduce the size of my code and not create extra complexities that will accelerate software obsolescence and hardware obsolescence?” But that's a very important battle as well. Can I ask you a final question on best practices? And I know Anne that there is quite a lot of good and sound advice in your book, and Arne, you already touched upon them a bit and if you want to comment, just feel free. But maybe, Anne, as one of the three authors of the next O'Reilly book, what are the best pages?[00:52:01] Anne: Well, the introduction summarizes everything in the whole book, and that's already available in very rough, pre-release form, on the O'Reilly website. And you don't even have to buy an O'Reilly subscription, because you can just do a trial and you can have a quick read of it. And eventually, when it's finally published, the whole book will also be simultaneously public, open sourcing. But not until it actually is finally published next year. All of that will be available. So, principles - this is a horrible thing, nobody wants to hear this, no technology person wants to hear this, but really, the best practices don't focus on optimizing your own code. Instead use code that's pre-optimized by somebody else. Because that is by far the most effective thing you can do.  In the long run chat GPT is going to become much better at optimizing; compilers are getting much, much better at optimizing code. You try and push that job off on to somebody else. But do be thinking about architectures and designs that will work with time-shifting. Things like spot instances, and micro services where you can turn things off, as Arne mentioned, or you can time shift them. Think time shifting first is my advice.[00:53:21] Gaël: I guess, because you're influenced by your science fiction work and you want to travel across time, and this is why you're so obsessed by time-shifting! But it is finally happening. What about you Arne, do you want to travel in time again?[00:53:41] Arne: Yes, as I said before, I also think that time shifting will be one of the bigger gains in the future. And embodied carbon is one of the bigger battles to fight, although there, I don't really know how the optimizations will play out because it's so opaque at the moment, as most people don't even know how, for instance, S3 is implemented. And what kind of hard disk, so it's very hard to say how optimizations could even work for a system like this, which stores, I think, most of the of the data that the Internet holds at the moment. I think my take on optimization techniques is very simple. Although we speak a lot about these, as I mentioned before, particular, vector instruction techniques, and these energy and performance metrics anomalies, so we speak about them because developers like to hear these super funny edge cases where something goes horribly wrong. But I think for a daily business, if you really want to save energy in your code, most developers know how to do it. So, there's really nothing you have to tell the developers really, to do. It's more that they are overwhelmed, as business is not giving them the time and the support to do it. I would really say that the particular key [issue] at the moment is transparency. Wherever you can measure your stuff, even if it's not the best metric, make it public, if it's on your own block, or if it's in the git-hub repository, or even if it's just in your notebook, that you at least know what your code is doing. And then the other thing is, to ask your management how much is our code emitting? Can you [management] not supply these numbers? « Ask the cloud providers » is also something that Anne mentioned, which I think will drive a lot of the transition - you have to ask for these metrics. For instance, if I go to the supermarket and I always buy a product, and I'm always angry that it's not packaged in recyclable paper yet I never ask the vendor [about the packaging], how can something change. There is no mind transition [reading]. I don't know what the English term is for It, when my mind goes into his mind, and so he obviously knows that I'm happy (or not) with the product. I have to ask for it [change). So, I think this is really the key, and such techniques like time-shifting. And I really have to say, and maybe this is a bit of belly rubbing for you, Gaël, we should listen to podcasts like Green I/O because you will hear about new techniques that developers find, that are useful and that should be employed.[00:56:01] Gaël: Well, thanks. And that's a beautiful transition to my last question, which is what are the main resources you would advise the developer community to go for, when trying to green their code. But Anne, you cannot mention Environmental Variable because I’m going to do it first and give a big kudo to Chris Adams and Assim Hussain and the wonderful work they do with the regular guests like you. So environmental podcasts are Definitely podcasts to listen to and I personally I'm listening to pretty much every episode. I've taken this example, so you need to find another one![00:56:38] Anne: Well, of course I'm going to mention my book.  “Building green software ».  And I have good reason for mentioning this because we are publishing it every month. Ideally, hopefully, we'll be dropping a new rough early chapter, and we're looking for feedback. So, contact me at: buildinggreensoftware@gmail.com, and you'll be able to send us feedback for what you'd like to see in the book that has not already been covered. So, if there are questions whilst you are reading it, contact me - I'm on Twitter, Sara's on Twitter, Sarah's on LinkedIn. We're very happy to hear you come back and say « But I wanted you to answer this question ». We will attempt to answer the questions.[00:57:24] Arne: I’ll also pick up the question, so, I'm monitoring what’s out there a lot. I have Google alerts that alert me about new stuff coming out. I read the Green Software Foundation newsletter. I read the Climate Action Tech newsletter. I'm a follower of this podcast. But I would say that there is no one [single] resource. I think this is what you what you are shooting for Gaël? So [for me] there is no one central place where you can find the all the best information. But if I have to name something that I think has given me the most value so far, with the most helpful techniques, it is from conferences. I think if people get a conference talk in somewhere where you have a sustainability track, [it gives you] that something that is a bit bigger, something to be watched. I think if you just want to follow one resource in particular, get an alert of something like sustainability conferences or sustainability tracks at IT conferences. I think it’s there that I've seen the most valuable content.[00:58:27] Gaël: Well, that's music to my ears knowing that I will be in charge of the Sustainability track both at ‘Apidays’ in London and in Paris later this year. I've got a big blessing from you. Thanks a lot. But yes, that's so true, conferences, they're cool. I mean, you can interact, you can discuss with your peers, and that changes everything, I guess from, being just a passive listener. And, no, I didn't aim for a single source of truth. I'm always a bit dubious with these approaches, but, that's great, actually, that you mentioned conferences because we tend to mention articles, podcasts, etcetera. So yes, conferences and the big fight made by the Green Software Foundation. I mean, they've got a speaker repository now, and I know that their approach is no conference today in tech can spare having a sustainability track, or at least some talks on sustainability. And I think that's a great approach. And I've gathered people from all over the world saying, « Hey, these folks ((are good speakers)), and as far as I remember, both of you are in this cohort of speakers in IT/TECH/sustainability, and I am well as well (full disclosure!) But, these folks, they can talk, if you cannot find anyone, then just connect with them. But you cannot have a big conference without someone talking about carbon, sustainability and so on, so it makes definitely a lot of sense. Well, thanks a lot, both of you. That was a very lively discussion. I really enjoyed it and letting you converse with each other. That was really was music to my ears. So, I'd like to thank you once again for all the feedback and insights that you have shared with us today. Once again, thanks a lot.[01:00:16] Arne: Thank you, Gaël.

Welcome to Green IO, the podcast for doers making our digital word greener, one byte at a time. I'm your host, Gael Duez and I invite you to meet a wide range of guests working in the tech industry, to help you better understand and make sense of its sustainability issues and find inspiration to positively impact the digital world.If you like the podcast, please rate it on Apple, Spotify or your favorite platform to spread the word to more responsible technologists like you. And now enjoy the show. In this episode, we go to Germany to meet Vanessa Forti and to Runda to meet Jacqueline Mukarukundo to talk about electronic waste or e-waste. You know, once someone tries to run a proper lifecycle assessment of a digital service or an IT equipment, E-waste is often narrowed down to "yeah, we know it's bad, but we don't have any data to quantify it".Well, there is actually a big source of information, at least on the quantitative side, which is a global e-waste monitor published by both the United Nations University (UNU) and United Nation Institute for Training and Research (UNITAR), and Vanessa the associate program officer at UNITAR, is the lead author of the 2020 edition.She's also a true European globetrotter, an Italian who graduated as an environmental engineer in Italy, did research works in Norway and in the Netherland on circular economics metrics, especially on metals. In a nutshell, could we dream of a better expert to be with us? Well, we could dream of having someone bringing also experience on the e-waste circular economy, having her hands full of its potential as well as challenges. This is why I'm delighted to have Jacqueline to bring a unique perspective on e-waste. Jacqueline is a Kigalian entrepreneur who co-founded Wastezon almost four years ago. Her work has earned her many awards and a wide recognition as an inspiring African woman leader. Currently, she's also working on the Africa Smart Cities Investment Summit, which will be held in Kigali from the 6th to 8th of September this year.To be honest, she's also the kind of person whose entrepreneurship helps me remember that many of us in the so-called global north take things for granted and complain about issues that will build joke elsewhere : not having received or delivery in 24 hour, finding how to recruit talents. Well, when I first discussed with Jacqueline about the best time to record our session, she told me that morning is better because there is less power outage in Kigali at that time.Hence, a better internet connection and still her company is thriving, food for thought. Welcome, Jacqueline and Vanessa. Thanks a lot for joining Green IO today. Vanessa: Thank you. Thank you for the invitation.Jacqueline: Thank you for having me.Gael: My pleasure. I'd like to start with the usual question I asked to my guest, which is how did you become interested in sustainability? E-waste in specific, but sustainability in general. Jacqueline, did you experience some kind of like "bubble moment", for instance?Jacqueline: Wow, that's a very good question. So I remember very well that I became interested in sustainability when I realized the harmful impact of electronic waste on environment and people's health. This was actually in 2018 when, back then, basically I was after high school and starting university and I started to realize these specific issues of how we deal with electronic devices we have in our house, specifically in my country, but also in developing countries like Africa.So this literally worked me out to start to think about how I can bring up solution to the table and specifically green technology industry cause that's one of the things which I'm missing in African countries. So I saw an opportunity to create sustainable solution to this problem. Also I wanted to focus on reducing and creating environmental impact of electronic waste.In that moment, while I can also create economic opportunity for communities, basically creating a win-win solution to both those who have electronic waste, but those one who correct it, which are electronic recycling industries. So, I never really experienced a light bomb moment, but rather a gradual awareness of the importance of sustainability in our business practices, but also it's a positive impact on society and the planet.So I would say that this awareness has really fueled, kind of feeded me, my passion for creating innovative solutions, but also sustainable activities to the environmental challenge. So at the moment, I feel like I'm very inspired to continue to create positive impact that can work and have a larger impact to the whole world.Gael: Yeah, that's interesting because it's really about focusing on the impact and not focusing too much on the problem, which is obviously something that we will discuss about the e-waste. And what about you, Vanessa? How did you become the environmental engineer that you are today and working so much on the e-waste area I would say?Vanessa: Thank you Gael for the question and this enables me to look back when I was a child. I remember that at elementary school, I had a teacher that was teaching us how to fold plastic shopping bags in a proper way so that you can store it in your drawer and reuse it when you need it instead of throwing them away. I remember that lesson, in a very clear way. That was very inspiring for me when I was a child. Since then I started indeed folding shopping bags and keeping them just for reusing instead of buying or getting new ones.So I would say that is a light bubble moment I had in my life. And since then I've always been sensitive to environmental issues. Also my parents remember I was getting mad at people when, in the 90s when I saw them throwing things on the street and back then it was pretty common. So I guess since then I really hated the waste problem. I wanted to do something to improve also the sustainability in general. At least I tried to do simple actions so that I could improve at least a little bit from my side. The little world I was living in. Since then, I always had that interest and I continued my path by studying environmental engineering.Then the driver was ready to try to find solutions indeed, to the problems. I've also been very much interested in developing solutions because we know there's many problems out there. We need to find solutions to leave a better world for the future generations as well.Gael: Excellent. So, Vanessa, I read, not entirely, but a good chunk of the global e-waste monitor because I wanted to get some sense of proportion. So in the global e-Waste Monitor 2020, it is assessed that 53.6 million metric tons of e-waste was generated worldwide. And I was curious to see how I could compare.So I calculated the weight of an Olympic swimming pool, and I got that actually this amount is 21,440 Olympic swimming pools. And you know what? I couldn't yet truly picture what 21,440 Olympic swimming pool meant, so I converted them in square kilometer, which is 26.8 square kilometers, and it is roughly a quarter of the area of Paris, okay. Not exactly but roughly.So if we want to store all the West generated in the last four years worldwide, we will need to erase Paris and replace it by swimming pools in four years. So providing that the density of electronic equipment is closed to the density of water, which is not the case. So we might save some presence luckiest.This data. Well, they, they were just super impressive and I wanted to ask you, where do they come from and how are they crunched? How do you build such a database?Vanessa: Thanks for the question and thanks for making the comparisons. Indeed it's a lot of data and we do actually compile worldwide data on, well, we start from analyzing production and trade statistics at worldwide level. We do this exercise for all countries in the world that are UN member states.So basically we analyze the sales of electric and electronic products every year. Then we also analyzed and imports/exports and the domestic production. And these are data that are available to the open public as well because they're published in the UN Comtrade database.So what we did is to really have a list of all products that are, that can be classified as electric and electronic product and we compile all this information at global level. We make a simple calculation that it seems simple, but then when you run this model for all countries in the world, sorry, then this will of course increase the complexity.But the simple calculation that we do is imports minus exports, plus domestic production. So basically we account for whatever is sold in the country as such so whatever comes in, minus whatever goes out, plus whatever is produced domestically in terms of electric and electronic products. So that's the simple idea let's say, and then we link it to the lifetime of the products. So we made over the years assessments on by linking this average lifetimes to the sells, we would know when this product will become waste. So at the very end, we have a database that goes from 1980 up to the current year. Then we are able to make estimates also over time and we have made estimates up to 2050. So that's a bit how we come to those data and hopefully this provides a bit more insights also.Gael: Oh, he does definitely. And how accurate should we think about there's 53.6 million. Is it like plus or minus 5% or plus or minus 50%?Vanessa: Well, that's a good question actually. We have tried to assess this over the years, and all in all, we can say that we feel confident with the data that we provide and that we calculate because they're based on real data that are actually reported by countries. So the production and trade statistics are official data from countries.Of course there is a certain level of uncertainty when it comes also to domestic production because domestic production, it's an indicator that is not easily or readily available at international level, and many countries may not disclose that information or may not be available. So in that sense, indeed there is a certain level of uncertainty. However, the model compensates for potential lack of information at domestic production level, let's say.So we run many statistical corrections when we are on the model to make sure to really limit the level of uncertainty at the very end, we guess and estimated the level of uncertainties indeed around 5 to maximum 10%. But it would not be more than that in my view.Gael: Plus or minus 5%. So that, that gives a good idea of what kind of number we should share with the general public and you mentioned trends. Geographically speaking, but also maybe by time of equipments., What are the trends that you've noticed recently?Vanessa: When we look at the categories of e-waste the trends that we have observed is that of course temperature exchange equipment are growing at high speed. So there has been an increase of 7% compared to 2014, for example, and that's the highest grow rate among the 6 European categories. There is a very big growth on consumption on air conditioners, for example, in the global south that we have noticed in the past years and therefore this is definitely impacting the future e-waste generation for sure. When it comes to screens and monitors, for example, the consumption in terms of number of units is increasing and has increased a lot during Covid as well, especially because of the, we guess it's because of the increase usage of those appliances at home from smart work. Therefore we have seen an increase in that sense. However, at the same time, those screens and monitors are becoming lighter and lighter over the years. If we imagine that we transition from the old CRTs to the new technologies and screens that are now very flat and very light, they became much lighter.So in terms of weight, the screens and monitors is the category that is decreasing over time. But of course they're increasing in terms of number of units. Just to answer your question on the regional aspect and regional differences, we notice a rapid increase in new waste generation in the global south.Especially Africa has been contributing to the E-waste mountain with a lower speed compared to higher income countries. But African countries are now also showing a very rapid increase in the past years. So that's a trend that maybe makes sense to highlight as well as the Asian situation that of course, being Asia continent that is very populous with many billion people, of course, is the continent that is contributing the most to the global e-waste generation.Gael: And there is one figure actually that struck me, that we've got this big increase in e-waste, sometimes in weight, sometime in quantities and sometime in both. If I understood you well, especially regarding IT equipment, and then there is this recycling issue. I remember this number that less than 18% of a global e-waste is recycled.Can you tell us a bit more about it?Vanessa: Thanks. I think very relevant point to highlight. So the trend that I would like to highlight is that, we have noticed, the global e-waste recycled is growing at lesser of a speed compared to the increase of the speed at which the global waste generation is instead growing. The global waste generation is growing a much higher speed compared to the e-waste recycling figure, and that is for several reasons. The first and very important one is that, while the global waste generation is modeled, it's our data that are modeled with the model I just explained. The e-waste formally recycled is actually coming from data that we collect and gather directly from countries.So these are data that are reported by governments around the the world. So the figure reflects what is currently available at national governments. It is also true that many governments, especially in the global south, don't have this figure so don't gather the figure and therefore we do not receive information on the amount of e-waste formally collected.The reason could be many. The main one is that if there is no legislation in place, there is no formal obligation for governments to report on the e-waste formally collected. There is definitely also not a system in place to monitor the recycling facilities or to survey the recycling facilities.The second reason is also that, of course, the countries that don't have a legislation would hardly have a well-working e-waste management system because not having any obligation no business is willing to establish in a country. So it's a sort of a loop with no legislations, it is easier or let's say it is more difficult for the US recycling to establish. Other way around if no US recycling is happening, it's harder for the governments to regulate the subject for countries with the legislation instead. The recycling rates are still low nevertheless so if we look at Europe as well, where there is a redirective for many years and the e-waste recycling is very well regulated.But still most of the countries are far from reaching the collection targets.Gael: And taking a concrete example, Jacqueline, could you t ell us a bit more on the situation in Rwanda when it comes to legal requirements, recycling rate, etc. Is it something that you can talk about?Jacqueline: Yeah, so responding to that I would say that I don't have like accurate data to support it, but according to the observations and the experience I had, one of the main areas of similarity challenge developing countries are facing it's correction, as Vanessa said : The correction process and the capacity of recycling the issue of investment, but also automation about awareness, the effect of electronic waste.We may think that normal people or public doesn't have enough awareness of electronic voice, but one thing which was being able to visualize is that : you find that majority of people have electronic devices in their house where they have this specific particular small room in the corner of the house where they drop out, maybe tv, which no longer work, maybe dvd, maybe phones, or like this particular mouse or this model, electronic devices, which are no longer being used.They keep it in their houses for what? So first of all, they believe that these electronic devices has a value into it. So they're expecting at least to get a low cost amount of money, let's say maybe five US dollars according to the value of it, maybe 10 US dollars, particularly depending to how this holder of electronic devices feel like his electronic devices still has a value.But one thing which happened back and forth between all the stakeholders involved in electronic waste management industry here in developing country is that you find that some of recycling industries are not willing to compensate the cost value this electronic deficit may still have. Also those one who still have it in their houses, they refuse to give it back. And where to some point they feel like "okay, instead of giving to back, I will just send it to the landfill". So by sending to the landfill or at the downside that this increase the impact, the cremate and environment. So there is back and forth change and understanding the law each individual stakeholder must bring on the table.  That's why we find so many electronic devices on the dump sites, on landfill everywhere. You find recycling actors saying that they're not capable of finding enough tons of electronics they may probably need, for recycling just because there is misunderstanding the value law this electronic waste has. This bring us so much understanding why the cycling blade is still very low in developing countries. Every, if I could remember, probably still below to 20%. So basically that's the situation, how the situation is, and I would support what Vanessa was saying. This is a very huge challenge mainly when it comes to developing countries, even though currently is cross boundaries prohibition for electronic secondhand electronic devices.But still, it happened illegally on the block market. I think it's a bit chaos, but I say regulatory black market for electronic devices because some countries has already set cross boundaries, prohibition for electronic devices, but still for some reason it tend to be happen in one way or the other.So that's also increased a huge challenge to how to deal with electronic devices. Yeah.Gael: I've got a question for both of you, and this is a very basic question. How bad is e-waste? Obviously wasting things is not very good, but why do we focus that much on e-waste? And I've heard a lot of stuff about pollution, blah, blah, blah, et cetera. But I'd like to get your insights for both of you, both experts, regarding e-waste.Vanessa: E-waste is actually, well bad in my view, when it is not disposed in a proper way. So as Jacqueline also mentioned there are many illegal practices when it comes also to recycling. Many backyard recycling is happening in many countries in the world. And when this happens, without the proper safety standards and procedures it is very likely that the person that is handling the waste gets intoxicated or inhale toxic fumes by burning cables or plastics. The plastics that is usually burned is containing claim retardant substances. Those are the ones that are very toxic for the human being, but also for the environment in general.From what we have seen, this is a very easy way to get rid of the plastic and get to the available parts. For cables, for example, the plastic casing is incinerated. And then in order to extract the copper this is where e-waste becomes fed and toxic and polluting. In the landfills where these illegal practices are happening, we as senior collaborated with WHO in the past monitors and we found out that there is larger impacts that we could not think of before. Even kids are affected or pregnant women are also affected by the toxic substances that are released on the environment by bad waste management practices.Gael: And Jacqueline, is it something that you've witnessed it or that you can tell us a bit more about this non-proper waste disposal. There is a famous place, which is now closed in Ghana, which is at Agbogbloshie that used to be kind of a nightmare when it comes to a manage waste, electronic waste but, you know, it's just one example. I've always wondered if it was something that you could find elsewhere or if it was hopefully for Africa, just a single example of bad waste management.Jacqueline: So reason why e-waste is a very big issue, we tend to forget the reality of the world we are living. At the moment we are living the world where technology is the future. Everything is being turned into digital transformation is being turned to using ICT tools and all of that.But we tend to think the lifecycle of these ICT tools we are using in our everyday life, we cannot really forget that we have specific iPhone brands, which are already on market each and every year or every two year. Maybe I would say maybe iPhone 14, iPhone 13. You know, there is always new version of the market and as a human beings and as a customers, we are always ready. We are always ready to consume these electronic devices, new product, new brand at the market. But the reason why we need to emphasize on electronic waste effect and how we can deal with it, it's by this reality of always higher conception rate all over the world of electronic devices and always new technologies which are coming on the table.That's why we need to stress out a lot on electronic devices until we understand the life cycle system or secure economy of how new conception lead of all the branding new devices and all of that can be able to be treated. That's why manufacturers needs to come in.I liked Vanessa's research paper, how it was mentioning the lifecycles of electronic devices by mentioning when this could turn out to be e-waste.So by having all these supportive information and all the stakeholders on board, we can be able to deal with it. I would like really maybe to a repeat mention about the minors we find in electronic waste. Electronic devices have like a gold, silver, copper, and other variable materials into it.But most of these come from traditional mining, and we all know the effect of traditional mining. So with having urban mining in place, we'll be able to extract this gold and silver, and create recycling process to be reused once again instead of finding them on the dump side or at the landfill. So this is all the involvement of why we need to really deal with electronic devices.Yeah.Gael: And that comes at the perfect point in this discussion because what you're saying is actually because of this hyper consumption worldwide, that we've got more and more e-waste and actually e-waste is a good proxy for this hyper consumption of electronic equipments. We should pay attention to this indicator and still it has become, and it is become more and more a business to manage with this e-waste, what you call urban mining. I believe this is actually what you've done creating a business around circular economy and the Wastezon entreprise that you've created. So I would love to know a bit more about how you manage. Can you basically pitch us what Wastezon does?Jacqueline: Wastezon is still a startup, I may say. So basically what's Wastezon app, it's like connecting app between consumers or household manufacturers and recyclers who are looking for secondhand electronic devices or electronic waste. Where this app is being able to help with efficient tech empowered traceability services where it's helping them to generate value with value addition benefits to their electronic waste in environmental friendly. Where, as I said earlier, before, it's like a win-win situation where these manufacturers and cyclists need to understand that these people could get a value into their device they still have in their houses. Could be a little one, it's dependent negotiation between two parties who want to exchange these electronic devices.  Then I would say that for now we have more than 2000 users who were able to trust us and translate over 400 tons of electronic waste on our platform. This really brought our mind to- and it's sort of- show us that we are actually not even closer to where we are designed to be. We always meet, people are saying "oh, I actually have these laptops", "I have phones at home", "I don't have any clue where to send it" but I also, at the end of the day, I know that it still have a value the only issue may be my smartphone have, it's the screen and I know I can repair it, but I don't have time for it.So for us, we create a chain of value between two parties on Wastezon app to be able to sell between each other. So for the long term vision we have is to create a future of urban mining in electronic waste. Cause we realize that's where we are heading and this is the future and we have to believe it and see how we are heading. Talking about urban mining and how it's the long land vision for us is that we have seen how manufacturers are waking up to be part of this journey. I have seen amazing work, Dell and some other, like even Samsung is collecting like batteries. I think has started or it's part of the plan to start next year to start to collect batteries in east african countries, but also in some part of Africa because that is sufficient of our batteries minors to produce new ones. So they want to tap in into creating those one they already sent to the market and be able to process it once again. But also in a way of creating sustainability and environmental impact, which is the same thing Dell is doing I think in South America when I was reading the article in South America, in some part of India, I guess.So this is amazing and shows how manufacturers putting those producer responsibility in their hands. So that's where we want to here to be able to help these manufacturers to trace and know where there is a materials or e-waste where they can trace it and channel it to their recycling site where it's being based.So that's what we are doing at the moment and we are excited towards the future is holding for us. Yeah.Gael: So 400 tons is already a very significant achievement, so congratulations. My question would be just to understand, well, the word urban mining, these manufacturers and these recyclers, do they kind of extract the metals by, you know, melting chipboard, et cetera, et cetera? Or do they also manage to extract some spare parts that they will reuse in new equipments on the market?So is it recycling or is it just extraction of new resources?Jacqueline: Okay, so explaining what's exactly will be urban mining, how it's work. This kind of the time, which is sort of like a processing, recovering variable materials and other materials from discarded electronic devices and even those which are as in urban waste. So it's a form of recycling that's involved extracting and refining variable resources from West Stream that's were previously considered to be of a little or no value. So I give an example like a Samsung. So we have learned that they're going to start for them collecting batteries. This is part of urban mining cause when you find batteries, it has valuable materials inside. But now getting access to it- cause as we know that- to get these variable materials, normally it goes through the traditional mining.So getting access to these materials, it's tending to be very hard. These materials are re non-renewable, right? So how companies are tapping into it, they're extracting those minerals they need maybe gold, they need copper, they need aluminum, or they need batteries according to what they want to use with it. Battery could be used even to create electricity. There is an amazing innovation happening with regards to how batteries are turning into electricity like in India, in some part of the world. The extraction which happen it's in a way of creating, like creating the value of it, and being reused once again in form of circular processing, circular economy processing. Yeah.Gael: Yeah, it makes total sense. Is this extraction being done in, I would say good working conditions because both of you mentioned how toxic and dangerous can be waste and especially e-waste management previously. So these urban mining activities, you mentioned also that they're mostly done in the informal sector are workers or freelancers working in urban mining, getting more and more protected, or is it still a bit a Wide Waste I would say?Jacqueline: I would like to clarify that for Wastezon, you're not recycling industry sort of, so we have this is just a service we do to support recycling household and manufacturers in form of traceability and supply chain of these electronic wastes. But responding to that question, according observation, many countries are setting up policies which need to protect environment, but also people health.Here in Rwanda, the informal recycling doesn't no longer work because there is very strict, very strict policies for it, in form of protecting people. So I don't know how in other countries it's happening but I know that for sure based on the experience I had in Geneva last year when we were looking at the position of e-waste treatment in a developing countries.Many countries are setting up policies which need to prohibit and protect their people in terms of involving themselves in recycling or instruction of electronic devices. So I would guess that it's getting much better because of the involvement of both sectors, either on government side, but also on the private side, which are like entrepreneurs and yeah.Gael: Thanks a lot. And Vanessa, is it something that you've noticed also at a broader scale. Jacqueline mentioned the work done in Geneva, for instance. Things are getting better when it comes to urban mining?Vanessa: Yeah, yeah, sure. I mean I see a lot of improvements at global level for sure. At least in Europe, there's a nice and big networks of experts continuously working on improving the accessibility of CRMs. So critical raw materials through recycling and by mining indeed the waste that is a creditor, but across the globe I've seen very nice examples and startups and businesses establishing now in order to improve definitely the recoverability and recyclability of waste. So I'm optimistic about that. There's still a big and long path to get to the zero waste target or to the fully circular economy. But still I'm positive about it since I'm seeing very nice examples across the globe.Gael: And actually, could you elaborate a bit about the potential of switching to a more circular economy? Because we talk a lot about circular economy, but I'm not always sure that everyone has the same definition of it, and especially how much it will help reaching the the ODD and not only the environmental impact that Jacqueline mentioned already several times, and how big traditional mining has a toll on the planet, but all the ODD.Vanessa: Well, definitely, there are good benefits of adopting circular economy, approaches in the business sector. The way how circular economy is most commonly referred to as let's say the recycling part, right? So really recycling what is already waste and trying to get back the resources into the production chain.However, circular economy is much more than that, and it starts indeed with sustainable mining and if we talk of mining of new raw materials, ideally is already not a circular economy in a way because that means that we need extra resources to produce new products that we are not able to get back from the recycling at the end of life.So indeed it starts from the mining or the sourcing of the materials, and then it goes through the production phase and the usage phase. Also the eco-design is a very important aspect of circular economy that in my view, it has been explored very rarely I would say when it comes to electronics so far. The challenges of recyclers are still the same of 10 or 15 years ago, let's say.So it hasn't become easier to recycle electronics, but it has become rather more difficult nowadays because of the products has become lighter, more compact. There's no more possibility to replace parts of a mobile phone or a laptop. So I believe that when we talk of circular economy, we need to touch upon all aspects of circular economy, not only recycling.Eco design as a very important role and in addition what Jacqueline was mentioning, the production is also a very big role. Also not really decreasing production levels, but rather sustainable consumption of products is needed in my view to contribute to circular economy.Gael: So Jacqueline, don't kill me on sight because it might mean the end of your business. But if we really wanted to achieve a true circular economy, wouldn't mean to have an obligation for everyone manufacturing something to get it back at some point? You know, you manufacture a smartphone, you have to recover it, not your neighbor, not in another country, et cetera.But basically, if I buy a smartphone, even if I want to get rid of it either because it doesn't work or I want to change, I can go back to a shop or any shop actually and say, boom, "this is a Samsung smartphone, please put it in a box that should be shipped back to Samsung". I know it's a radical proposition, but I would love both of you to comment on it cause that will enable a more radical shift toward they could design.So what do you think about it? Is it me just being crazy?Jacqueline: So let me go first. Responding to that question, actually it has a positive, negative side, but I'm looking for positive side. So, first of all, the second hand market for digital equipment can really provide more opportunities for us, refurbishment and repair, repairing of electronics. This has a very core part of our own business at Wastezon. That means that there could be an increase in demand of our services actually. People would come back either to be like, "okay, have these devices". So I'd sell it to manufacturers or sell it to manufacturers, or I actually need to refurbish it and repair it on my own and reuse it once again. Also secondly, I would say as many people choose to repair or refurbish their electronic devices instead of buying new one. There is also a chance that we could be able to enhance and be able to see environmental impact, as I was always mentioning because of also this new regulation you were saying, which can come in place about repairability of taking back these electronics to the producers on manufacturers cause this is part of the extended producer responsibilities. That's the only way we are seeing the impact could be created. And for the negative side, I would say maybe potentially this would decrease demand for on electronic devices. For that it could affect the sales of a new electronic product and in turn, it could also end up impacting the volume of e-waste generated, but also the services we're being able to offer since people are sending it back. But also maybe no longer need this repairing and refurbishment at the same point. But the main important thing here, it's to always understand that the world is involving, and this is not about making money.The thing here, it's not about making money from waste. We are aiming for the social impact and creating share value benefit among all stakeholders, but most importantly to the world. So that's what we are aiming for. So we always try to stay up to date especially with coming with the technology needed at the market and how to make it easier to both involved people in those household and even those recycling or manufacturers.So that's how we stay positive into it.Gael: And what about you, Vanessa, what do you think about my crazy idea?Vanessa: Thinking more of a global level, this is something we have been discussing also in the context of EPR. No extended producer responsibility multiple times, and this was maybe even the original idea when this extended pro responsibility concept was designed. However, looking at the global dynamics and dimensions of the electronic industry, it does not be very easy to set up this system because as you can imagine there are few producers, larger producers in the world that are responsible for the majority of the production of electronics nowadays. But most likely they don't have one representated in each countries in the world.So this would mean also cross-country shipments. When it comes to cross-country shipments, that is also narrowed down to cross-country, let's say, legislations and agreements on this. So that is a bit of the reason, in my view, why it has been very hard to set up such a system. Ideally, it would be a nice solution for sure.So I agree with that. In practice, there might be challenges in doing that. But nevertheless the EPR concept somehow embeds this responsibility of producers because yeah, there is a obligation for taking back products. But nowadays, at least in Europe those products that are taken back and sent recycling are just a mix of different brands, they're not brand specific. There are some examples though, in the northern of Europe where brands have established their own recycling systems for only their own branded products and have developed technologies on how to optimize recycling for their products. And that may be a good example and it could be in the near future that we will see more than these examples.Gael: Oh actually Vanessa, that lead me to the final question to both of you. Could you share with us some resource about those initiatives and more generally what you advise us to read or to listen to understand a bit more the e-waste problem, but also some of the solutions that we are trying to put in place worldwide to solve it.Vanessa: Yeah, sure. In general, when it comes to Unitar definitely you can consult the Unitar website where you will have access to all projects we are working at, and to the results of most major projects. Then I think there you would have a very nice overview of what is the current e-waste situation at global level.Furthermore, we will, by the end of the year, publish a new version of the Globally Waste Monitor. It'll be at 2023 edition with an update of the data and with additional information, especially on recyclability. There's also websites that I mentioned before that is the globalewaste.org has been developed in partnership with the International Telecommunication Union and ISWA. Since we are partnering in a global e-waste statistic partnership. Recently, also United Nations Environmental Program and the Carac Foundation joined forces with us to develop the new globally waste monitor. So maybe that website will also provide updates with regards to data.Additional sources for those initiatives : well, I guess they're very dynamic and there are many updates every day and we actually are not, at the moment, compiling all those updates. But I suggest to follow main brands, the pages of main electronic brands worldwide and their sustainability area. There it will be every now and then available information on recyclability and the efforts that the producers do in terms of improving recyclability.Gael: And Jacqueline, do you have some materials as well? Documents, websites?Jacqueline: For me as an entrepreneur I would share obviously our website. It really shows more about our work. But the moment you're revamping, re-editing it to make it more professional, but it has everything and more information about our work and the links to our apps.It really shows about what you're doing and the impact you're creating. Additionally, I would also share the resources about this amazing article I was reading about urban mining. It has the title code : Urban Mining, the relevance of information, transaction costs and externalities. I found it on the Science Direct website.It's a very long one, but the thing I liked about it, it's really shows the data cause they corrected data among 2,500 Swiss respondents and they even did experience with 15,000 employees of Swiss institutions where they were trying to understand and estimate the reason why people do not particularly value their retired funds and how many of them are not willing to give it away, just like that.So it really shows the key output about urban mining and the future out of it. There is also this amazing article, which could be sort of like an example of how many big manufacturers are very keen to come in this journey of being responsible about the resources they're sending to the market and how they are involving in sustainability perspective like there is this also amazing article written by Apple. I hope I'm not doing advertise for them in this podcast, but it's a real amazing one. It's really shows how urban mining is the future. Apple was saying how they will use a hundred percent recyclable cobalt in materials by 2025. This is the approach they're going to take in terms of in industry reading innovation for their recyclable materials, batteries and even secular bulbs. So this is amazing. Actually there is so many amazing article out of there, which is showing how the involvement of different stakeholders in this journey will be exciting very soon.And hopefully the issue of e-waste be resolved no later than 2030 as SDG is aiming for.Gael: Well, thanks so much, Jacqueline, and don't worry. Apple will not give any money to this show so you are free to quote them, to mention them, because I'm not sponsored at all.And if I was sponsored by Apple, I guess it will drain a bit less money on my personal resources to run this show.So feel free to mention everyone you want. You've already mentioned Samsung and Dell, so that, that's perfectly fine. Well, Thanks a lot, both of you, because I've learned a lot of things. That was an episode I really wanted to offer to the audience because we talk that much about e-waste, but it's such on a superficial level and having two of you in the show explaining the data, but also what it meant concretely, the business impact.That was great. So once again, thanks a lot for joining and I know that many of us, we will have learned a lot of things listening to both of you. So thanks a lot again.Jacqueline: Thank you so much.
