Send me a messageHow do we scale nature-based carbon removal without greenwashing or over-promising? That’s exactly what I explore in this episode with Lisett Luik, co-founder of Arbonics.We all know forests are powerful carbon sinks. But turning that into credible, measurable climate action is harder than it sounds. Lisett shares how Arbonics is using satellite data, digital twins, and over 50 layers of land analysis to help landowners across Europe grow new forests or manage existing ones for long-term carbon storage, without defaulting to clear-cutting or monoculture plantations.We discuss the difference between planting trees and restoring ecosystems, how continuous cover forestry can deliver carbon and timber, and why Europe’s underused farmland holds massive potential for afforestation. Lisett also tackles the big issue of trust in carbon markets - explaining how dynamic baselines, data transparency, and strong EU regulations are helping improve the integrity of nature-based carbon credits.If you work in sustainability, forestry, or carbon markets, or you just want to understand the real role of nature-based solutions alongside tech like direct air capture, this episode is for you.Listen now to learn how technology and nature can work together to deliver scalable, high-quality carbon removal.Find out more at https://arbonics.com, and connect with Lisett on Bluesky here.Digital Disruption with Geoff Nielson Discover how technology is reshaping our lives and livelihoods.Listen on: Apple Podcasts   SpotifySupport the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of the Climate Confident podcast, I spoke with Laura Miranda Perez, Chief Communications & Sustainability Officer at Oxford PV, about one of the most important developments in solar tech today: perovskite-silicon tandem solar cells.We unpacked how Oxford PV’s approach improves solar panel efficiency from the typical 20–22% to over 30%, and why that matters not just for land use, but also for grid capacity, system costs, and the speed of global decarbonisation. Laura also explained how tandem cells work, why silicon has hit a performance ceiling, and how perovskite offers a new path forward.We dug into the real-world implications:Why higher efficiency panels lower the cost of electricity, not just hardwareHow tandem solar can reduce emissions by 20% or more, even compared to conventional solarWhat’s holding Europe back in solar manufacturing, despite strong deployment figuresWhy utilities, not just residential customers, are driving early demand for Oxford PV’s techLaura also addressed common misconceptions about solar, including whether it works in cloudy weather and the overblown concerns about solar panel waste.If you’re working in clean energy, manufacturing, or just curious about where solar is headed, this is a must-listen conversation.🔗 More on Oxford PV: https://www.oxfordpv.comListen and subscribe at https://www.climateconfidentpodcast.comDigital Disruption with Geoff Nielson Discover how technology is reshaping our lives and livelihoods.Listen on: Apple Podcasts   SpotifySupport the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of the Climate Confident podcast, I speak with Alexei Beltyukov, co-founder of Universal Fuel Technologies, about a new approach to producing Sustainable Aviation Fuel (SAF), using a process they call flexiforming.Unlike traditional methods like HEFA or Fischer–Tropsch, flexiforming allows producers to use a much wider range of feedstocks, from mixed alcohols to naphtas and renewable waste streams, and turn them into jet fuel, renewable diesel, or chemicals. This flexibility is critical as SAF demand surges, especially with EU mandates requiring a rising share of SAF in jet fuel starting in 2025.We explore:Why SAF is the only viable decarbonisation path for long-haul aviation (for now)What sets flexiforming apart from conventional SAF productionHow current SAF mandates and incentives (EU vs. US) shape supply and pricingWhy scaling SAF requires compatibility with existing refinery infrastructureThe role consumer awareness might play in driving airline demandAlexei also makes the case for slow but steady growth in SAF adoption, pointing to its current double-digit annual growth and comparing its trajectory to that of electric vehicles 10 years ago.If you're working in energy, fuels, aviation, or sustainability policy, or you’re just trying to understand how we decarbonise one of the hardest-to-abate sectors, this episode offers a clear, grounded perspective.🔗 Listen now and learn more at climateconfidentpodcast.com#sustainableaviationfuel #SAF #decarbonisation #aviation #cleantech #climatechange #renewablefuels #energytransition #climateconfident #podcastSupport the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of Climate Confident, I speak with Alice Chun, inventor of the world’s first inflatable, origami-inspired solar light and founder of Solight Design. Alice shares how a career in material technology and a deeply personal experience with her son’s asthma led her to tackle energy poverty, disaster relief, and carbon emissions with a single, deceptively simple product: the SolarPuff™.We discuss the staggering health and environmental toll of kerosene lighting, especially in off-grid and disaster-affected communities — and how collapsible, durable solar lanterns are not only cleaner and safer, but can also act as tools for education, safety, and psychological recovery.Alice walks us through the practical design choices (like sailcloth and origami folds) that make the lights lightweight, shippable, and long-lasting. She also unpacks her field experiences from Haiti to Ukraine, why she insists on personally delivering lights, and the complex balance of running a mission-driven company that also needs to survive commercially.Key takeaways:Why light access is essential for disaster resilience and safetyHow solar design can scale through beauty, durability, and functionThe unexpected link between solar tech and trauma recovery in childrenWhat business models can sustain social impact in climate techFor more, visit https://solight-design.com or head to climateconfidentpodcast.com.Digital Disruption with Geoff Nielson Discover how technology is reshaping our lives and livelihoods.Listen on: Apple Podcasts   SpotifySupport the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of the Climate Confident podcast, I spoke with Ryan Schermerhorn, a US-based patent attorney who’s been helping clean tech innovators navigate the IP maze - until recently with the help of a now-suspended fast-track programme.We discussed the United States Patent and Trademark Office’s (USPTO) Climate Change Mitigation Pilot Program, which allowed inventors of emissions-reducing technologies to get patents approved in months rather than years, at no cost. Ryan explained how it worked, why it was a big deal for clean tech startups, and how it quietly disappeared earlier this year following a political shift.We also unpacked what this means for innovators now. Ryan shared practical alternatives - like using international patent offices with similar climate fast-track schemes and leveraging the Patent Prosecution Highway (PPH) to speed things up globally.We also covered the balance between IP protection and open innovation, why patents still matter in the climate crisis, and how to protect ideas early without blowing the budget.If you're working in climate tech, clean energy, or emissions monitoring and need to protect or scale your innovation, this episode is for you.Support the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of the Climate Confident podcast, I sat down with Faustine Delasalle, CEO of the Mission Possible Partnership (MPP), to delve into the real challenges, and opportunities, of decarbonising heavy industry and transport.Faustine and I explored the current state of industrial decarbonisation, including the progress made over the last five to six years in proving that sectors like steel, cement, and shipping can transition to low-carbon alternatives. But as she points out, technical feasibility doesn’t always translate into financial viability. The sticking point? Making green industrial projects bankable.We discussed the role of the so-called "green premium" (or dirty discount), why demand signals are crucial, and how the current lack of buyers at scale is stalling momentum. Faustine makes a strong case for the combination of policy mandates and targeted subsidies to unlock investment - drawing comparisons with the growth trajectories of solar and electric vehicles.A key takeaway from our chat: the path to scaling green hydrogen could start with ammonia, which Faustine sees as the first domino in the next industrial revolution. We also looked at which regions are moving fastest, what’s holding others back, and why emerging economies might play a central role in the coming decade.If you're in policymaking, finance, or industry, and serious about accelerating climate action, this is one to tune into.Listen and follow Climate Confident wherever you get your podcasts.Support the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of Climate Confident, I sit down with Chris Doherty, CEO of Joulen, to discuss how data, AI, and battery storage are changing the way homes and businesses interact with renewable energy. With energy costs fluctuating and grid constraints becoming more of a challenge, the role of smart energy management has never been more important.Chris explains how virtual power plants (VPPs) allow households and small businesses to collectively act as a large-scale power provider, reducing costs and generating income. We explore how AI-driven algorithms optimise energy use, ensuring that people buy low and sell high—maximising savings and revenue.We also break down the regulatory barriers that prevent wider adoption of decentralised energy and discuss what governments can do to speed up the transition. From Germany’s success in residential battery storage to the UK’s evolving energy market, we look at how different countries are tackling these challenges.Other key topics:Why EVs with vehicle-to-grid (V2G) technology could replace home batteriesHow energy storage can help stabilise the grid and reduce investment in new infrastructureThe financial incentives needed to scale solar and battery adoption in homes and businessesThe growing role of demand-side management in balancing electricity supplyIf you’re wondering how to make the most of your renewable energy system—or how policy can unlock wider adoption—this episode has you covered.📩 Get in touch: tomraftery@outlook.com💡 Follow for more insights on the clean energy transition.Support the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.

Send me a messageIn this episode of Climate Confident, I sit down with Jenny Morgan, author of Cancel Culture in Climate, to explore how public shaming and polarisation are holding back real progress on climate solutions.We already have the tools and technologies needed to reduce emissions, yet fear of criticism—whether from activists, media, or the public—often paralyses businesses and leaders. Jenny explains how cancel culture leads to three major pitfalls:Greenwashing – Overstating sustainability efforts to avoid backlash.Greenhushing – Staying silent about genuine climate initiatives to escape scrutiny.Green recanting – Companies reversing climate commitments due to heightened pressure.Rather than tearing down imperfect efforts, Jenny advocates for empathetic accountability—holding organisations to account while keeping the door open for progress. We discuss how companies like Patagonia and Allbirds have embraced transparency over perfection, and how social media can be both a force for good and a major obstacle to climate communication.Key takeaways:✔ Why fear of being “called out” prevents meaningful climate action.✔ How businesses can regain trust after sustainability missteps.✔ Practical strategies to foster productive climate conversations.Tune in to rethink how we approach climate accountability—and why working with people is more effective than working against them.🔗 Listen now and subscribe in your favourite podcast app.Support the showPodcast supportersI'd like to sincerely thank this podcast's amazing supporters: Lorcan Sheehan Jerry Sweeney Andreas Werner Stephen Carroll Roger Arnold And remember you too can Support the Podcast - it is really easy and hugely important as it will enable me to continue to create more excellent Climate Confident episodes like this one.ContactIf you have any comments/suggestions or questions for the podcast - get in touch via direct message on Twitter/LinkedIn.
