Podcasts about carbon removal

In this edition of Plan Sea, hosts Anna Madlener and Wil Burns kick off season three of the podcast with Woods Hole Oceanographic Institution (WHOI) researchers Dr. Adam Subhas and Jennie Rheuban to discuss the LOC-NESS project — a small-scale, open-ocean research trial on ocean alkalinity enhancement (OAE). The project's co-principal investigators join Anna and Wil to recount the process of receiving a first-of-its-kind permit from the U.S. Environmental Protection Agency (EPA), the role of local community engagement, and the project's early findings. A few weeks ago, WHOI completed its highly controlled research trial in the Gulf of Maine to study the environmental safety and efficacy of OAE as a carbon dioxide removal technique. Approved by the EPA after a two-year, rigorous permitting process, the LOC-NESS project introduced small amounts of purified sodium hydroxide – a compound often used to balance the pH of drinking water – to the ocean surface waters, along with a harmless red dye to help track it. This field study came after years of preparation and development, including extensive laboratory experiments, ocean modeling, and a growing body of scientific literature. Dr. Adam Subhas is an Associate Scientist at WHOI and the project lead for LOC-NESS. Adam credits the project's success so far to the comprehensive preparation and collaboration between WHOI scientists and EPA staff — on everything from ocean modeling and biogeochemical impact evaluation, to engaging communities and local industries on what to expect from the research. He also talks about how their pursuit of the first-ever ocean carbon dioxide removal (oCDR) permit under the Marine Protection, Research, and Sanctuaries Act of 1972, helped the LOC-NESS team refine their procedures, improve their approach, and make the project more responsive to feedback from their community.Jennie Rheuban is a WHOI Research Specialist and serves as a co-principal investigator for LOC-NESS. Jennie points to community engagement as a critical component of LOC-NESS's development, recounting the project's years-long effort to engage with questions from a range of stakeholders, including the fishing community. By emphasizing its position as an independent scientific research project without commercial ambitions, WHOI was able to cultivate credibility and gather important community inputs that shaped the scope and methodologies of the research. For example, the team spent additional time researching types of fish larvae in potential field trial regions to bring that information back to the local fisherman.Looking ahead, LOC-NESS researchers will continue to analyze data gathered during this summer's trial to understand the impacts and efficacy of the alkalinity dispersal. More information about LOC-NESS's findings will be shared at the Ocean Sciences Meeting in February 2026.Plan Sea is a semi-weekly podcast exploring ocean-based solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal. Plan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.

Even if we do everything we need to do to limit our carbon emissions—curb deforestation, stop driving so many miles, clean up our power grids—we still need to remove gigatons of carbon from our atmosphere to meet our climate goals. Carbon removal is still a new technology, and while carbon removal companies removed roughly 35,000 tons of carbon last year, we have a long way to go. Luckily, there are people working on creative ways to raise the capital needed for development of this crucial tech. Ryan and Anjali chat with Nan Ransohoff, Head of Climate at the online payment company Stripe, and learn about her efforts to invest in carbon removal, and encouraging other big companies to remove 10 million gigatons of carbon each year by 2050.

In this week's episode, host Daniel Raimi discusses carbon removal with Jennifer Wilcox, a professor at the University of Pennsylvania who recently coauthored a paper titled, “Elevating Carbon Management: A Policy Decision-Making Framework and Rubric for the 21st Century.” Wilcox discusses the existing gaps in current policies related to carbon removal and important considerations when amending and creating new policies. She also addresses the recent change to the 45Q subsidy (originally included in the Inflation Reduction Act of 2022 and revised by Congress in the budget reconciliation bill signed on July 4, 2025), assessing how the updated tax break offers incentives for carbon removal. “Elevating Carbon Management: A Policy Decision-Making Framework and Rubric for the 21st Century” by Jennifer Wilcox, Noah Deich, and Holly Jean Buck; https://kleinmanenergy.upenn.edu/research/publications/elevating-carbon-management-a-policy-decision-making-framework-and-rubric-for-the-21st-century/ National Park Service Rehabilitation Tax Credits; https://www.nps.gov/subjects/taxincentives/index.htm

Steve Oldham is CEO of Captura. Captura develops Direct Ocean Capture (DOC) technology that removes CO₂ from seawater, triggering the ocean to draw more CO₂ from the air to rebalance. With CO₂ concentrations ~150× higher in seawater than air, Captura's closed-loop process uses electrodialysis to create acid and base on site—no added chemicals, no waste—and can run largely on off-peak renewable energy. Oldham, former CEO of Carbon Engineering, contrasts DOC with DAC, discusses MRV and crediting, deployment pathways (onshore, barges, vessels), his company's pilot progress in Hawaii, and why pragmatic scale-up and licensing partnerships matter for gigaton carbon removal. Episode recorded on Aug 28, 2025 (Published on Sept 30, 2025)In this episode, we cover: [02:17] Steve's path from Carbon Engineering to Captura[05:30] How Direct Ocean Capture actually works[09:10] Closed-loop design with no waste products[10:14] Using electrodialysis to split acid and base[13:12] Deployment options: onshore plants, barges, vessels[14:39] Running on off-peak and curtailed renewables[16:30] Measuring and crediting carbon drawdown[21:53] Balancing CO₂ use vs. permanent storage[25:22] Policy gaps like 45Q for ocean removal[35:15] Captura's Kona pilot built in 70 days[37:33] First commercial project expected in Europe Enjoyed this episode?

Agricultural byproducts like corn stover, wood chips, and soybean husks typically get left to decompose and release carbon dioxide. Don't call them “waste” though; some farmers use these byproducts as field cover to improve soil health. And industry uses a fraction of this biomass as feedstock for valuable products like ethanol, electricity, and heat. Theoretically, it's a vastly underutilized resource.  The problem is that agricultural residue is really hard to collect. The economics of gathering, sorting, processing, and refining are tough. On top of that, it makes for a crappy fuel. It's low energy density and high carbon, compared to oil, for example. So in what applications does agricultural residue make the most sense? And how do you economically collect the material at scale? In this episode, Shayle talks to Peter Reinhardt, co-founder and CEO of Charm Industrial, a carbon removal startup that collects agricultural residue and refines it in the field into what it calls “bio-oil.” It then injects the bio-oil underground for sequestration. Together, Peter and Shayle discuss the use cases and collection of agricultural residue, covering topics like: How the difficult economics of collecting and transporting biomass have killed centralized biomass projects, except in a few niche examples Why Peter says the processing and densification are key to improving the economics The tradeoffs between big, centralized processing facilities and Charm's on-field mobile pyrolysis units The case for using agricultural residue for applications where the carbon content matters, like iron-making, sustainable aviation fuel, and carbon removal What's driving carbon removal buyers and what it takes to build trust with them Resources: Catalyst: Fuzzy math and food competition: The pitfalls of sourcing biomass for carbon removal   Open Circuit: What we learned from the ethanol disaster   Catalyst: Shopify's head of sustainability on the realities of the carbon removal market   Catalyst: From biowaste to ‘biogold'   Credits: Hosted by Shayle Kann.

Dr. Stephen Beaton is Co-founder and CEO of Circularity Fuels, which develops compact reactors that turn waste carbon streams into high-value fuels and chemicals. Rather than compete with fossil fuels from the start, Stephen identified high-purity methane for lab-grown diamonds as a beachhead market—where Circularity's product is 80–90% cheaper than incumbents while proving the core technology needed for clean liquid fuels.Stephen earned a chemistry PhD at Oxford and built deep expertise in synthetic fuels during his U.S. Air Force career, including overseeing jet fuel quality control in the Middle East and launching the Air Force's e-fuels program. His insight: build a fuels company that doesn't begin with fuel.Today, Circularity Fuels operates demonstration reactors in diamond facilities and is scaling toward biogas-to-SAF production using the same reactor platform. The company has raised $3M in venture funding, including from DCVC, plus $5M in grants from ARPA-E, NSF, and the California Energy Commission.

The carbon removal industry stands at a crucial crossroads. While cutting emissions remains essential, avoiding catastrophic warming now requires pulling billions of tons of CO2 from the atmosphere permanently. But as this nascent field grapples with questions of legitimacy, scalability, and accountability, a critical challenge remains: How do we build the infrastructure needed to track, verify, and certify that carbon has actually been removed and stays removed? Meet Hannes Junginger-Gestrich, CEO of Carbonfuture, a company helping define the monitoring, reporting, and verification (MRV) infrastructure that could transform carbon removal from scattered efforts into a functioning ecosystem. Launched five years ago, Carbonfuture has emerged as what CDR.fyi describes as "the largest facilitator of durable carbon removal" by volume. The company's digital platform integrates data across the carbon removal life cycle, connecting diverse approaches like biochar, enhanced rock weathering, and direct air capture with buyers seeking to meet climate commitments. "We are probably more the crowd, the ground keepers in a stadium that makes sure that everything is provided properly," Hannes explains, using a sports analogy to describe their role: "We are the ground keepers in a stadium [who ensure] the players have a playing field that's in shape and no one gets hurt, and the audience can come and they pay their tickets and have a good experience."The MRV infrastructure becomes crucial as corporate demand for verified carbon removal grows and trust becomes currency. One of the most interesting aspects of the conversation centers on balancing data confidentiality with transparency needs, particularly when collecting data along industrial value chains from agricultural residue producers to biochar processors to end users. Perhaps most telling is Junginger-Gestrich's unwavering commitment to scientific rigor over short-term economic gains: "We never had to trade off between rigor and allowing a not so good project on our platform for economic reasons. We always lean to the scientific and rigorous side." This philosophy has guided Carbonfuture's work with leading buyers like Microsoft, helping develop increasingly sophisticated approaches to carbon removal verification. While Junginger-Gestrich expresses concern about delayed emission reductions globally, he remains optimistic about carbon removal scaling: "I think we will be on the path to the gigatons by 2040 for sure." His vision emphasizes ecosystem thinking over vertical integration, aiming to drive down costs while creating network effects that could accelerate the entire field. As governments worldwide grapple with climate policy, the monitoring, reporting, and verification systems companies like Carbonfuture are developing now may well determine the success of our collective effort to reverse climate change.

What is carbon mineralization?As defined by the U.S. Geological Survey, “carbon mineralization is the process by which carbon dioxide becomes a solid mineral, such as a carbonate…The biggest advantage of carbon mineralization is that the carbon cannot escape back to the atmosphere.” This generally occurs by injecting carbon dioxide underground into certain rock formations so the carbon dioxide takes on a solid form: trapped and unable to reach the atmosphere. How does carbon mineralization work?Two of the main methods in which carbon mineralization occurs are ex-situ carbon mineralization and in-situ carbon mineralization. With ex-situ carbon mineralization, carbon dioxide solids are transported to a site to react with fluids—like water—and gas. In-situ carbon mineralization is the opposite—fluids containing carbon dioxide are funneled through rock formations in which it solidifies. Both of these methods result in carbon dioxide trapped in a solidified form. In a third method of carbon mineralization, surificial mineralization, carbon dioxide reacts with alkaline substances—such as mine tailings, smelter slags, or sedimentary formations—which result in the carbon dioxide taking on a solidified form. In the case of in-situ carbon mineralization or surificial mineralization, carbon dioxide can react with surface water rather than an artificial fluid, replicating natural processes of carbon mineralization.Currently, the biggest drawbacks and barriers preventing carbon mineralization from taking hold as a major climate solution lie in cost and research uncertainties regarding environmental risks. In terms of cost, the price for carbon mineralization is high: 5 million dollars per well to inject carbon dioxide into rock formations. Further, the risks for groundwater and its susceptibility to contamination through this method is unknown, and the potential side effects of contaminating water formations could be devastating for ecological communities which thrive off of these water systems.Who is our guest?Dr. Rob Jackson is a professor and senior research fellow at Stanford University, and author of Into the Clear Blue Sky, a novel on climate solutions. His lab focuses on using scientific knowledge to shape climate policies and reduce the environmental footprint of human activities. Currently, he chairs the Global Carbon Project, an effort to measure and control greenhouse gas emissions.ResourcesUSGS: U.S. Geological SurveyScienceDirect: A holistic overview of the in-situ and ex-situ carbon mineralization: Methods, mechanisms, and technical challengesNational Center for Biotechnology Information: Negative Emissions Technologies and Reliable Sequestration: A Research Agenda.Frontiers: An Overview of the Status and Challenges of CO2 Storage in Minerals and Geological FormationsFurther ReadingThe New York Times: How Oman's Rocks Could Help Save the PlanetClimate Break: Rerun: Using Concrete for Carbon Removal with Dr. Erica DoddsFor a transcript, please visit https://climatebreak.org/carbon-capture-mineralization-with-dr-rob-jackson/

The scale of our climate challenge is staggering: humans have pumped 1.6 trillion tonnes of carbon dioxide into the air and oceans since 1750, and we're adding another 40 billion tonnes every year. Even with dramatic emissions reductions, we're still on track to blow past 1.5 degrees of warming, the Paris Accord target first breached in 2024. Tune in to a conversation with Dr. Julio Friedmann, Chief Scientist at Carbon Direct. This carbon management company partners with Fortune 500 companies such as Microsoft, JPMorgan Chase, and American Express to transform net-zero commitments into science-backed action plans. After a career that began as a researcher at ExxonMobil and included service at Lawrence Livermore National Laboratory, Columbia University's energy policy center, and running advanced energy programs in the Obama administration's Department of Energy, Julio brings unique expertise to the intersection of massive climate challenges and current technological capabilities. As companies work toward 2030 and 2050 carbon goals, the question isn't whether we'll need massive carbon removal—it's whether we can deploy it fast enough and fairly enough to matter. The recent $100 million XPRIZE Carbon Removal awards highlighted the diversity of approaches being pursued, with natural solutions like enhanced rock weathering using basalt and azomite soil, and biochar applications to farmland dominating the winners. But how do these technologies stack up against the hype? Friedmann provides a realistic assessment of where Direct Air Capture, ocean alkalinity enhancement, and other carbon removal approaches stand today. Carbon Direct's team of 70+ scientists changes the conversation with corporate clients about their carbon strategies, providing the scientific firepower to offer hard feedback about what's needed to preserve the markets, supply chains, and revenue streams companies depend on.

Send me a messageIn this episode of Climate Confident, I spoke with Ori Shaashua, Co-founder and CCO of Gigablue, a marine carbon dioxide removal (mCDR) company taking a radically scalable approach to the carbon challenge.Gigablue's MCFS (Marine Carbon Fixation and Sequestration) method taps into the ocean's natural carbon cycle by cultivating phytoplankton in floating substrates and using gravity, not high-energy processes, to sink captured CO₂ to deep-sea sediment for thousands of years. It's a low-energy, high-durability method that's already secured the largest ocean carbon removal offtake to date.We unpack why mCDR matters, how it compares to nature-based and tech-heavy CDR approaches, and what makes ocean deserts, like those off the coast of New Zealand, ideal sites for safe and measurable sequestration. Ori also outlines their scale-up pathway: from kiloton removals today to multi-megaton capacity by 2029, and potentially gigaton-level by 2035.We dive into the mechanics of traceability, the real costs of permanence, and why MRV (Measurement, Reporting, and Verification) is the make-or-break for CDR credibility. Ori also pulls no punches on what's holding back progress: delayed regulation, weak compliance markets, and over-reliance on short-term carbon offsets.If your company is thinking seriously about durable net zero strategies, or wondering how ocean-based carbon removal fits into the climate tech landscape, this episode delivers real insight.

In this latest episode of Ed's occasional podcast Climate Book Reviews, we dive into the wildly imaginative and disturbingly plausible world of Ashley Shelby's acclaimed story collection, Honeymoons in Temporary Locations.Recently named one of Fresh Energy's Favorite Climate Books of 2025 and shortlisted for the Janet Heidinger Kafka Prize, Shelby's collection has been praised by Scientific American, Foreword, and the Post and Courier for its biting wit, emotional punch, and genre-bending storytelling.Ed is joined by his regular co-host Dr. Roger Thompson—now Director of Writing Programs and Professor at Arizona State University—for a lively, funny, and far-ranging conversation with Shelby herself. They unpack her satirical takes on resistance, inequality and privilege in crisis (think "luxury apocolypse bunkers”), and what it means to grieve - and medicate away - the losses brought on by climate change.Shelby's work has appeared in Slate, The New York Times Book Review, LitHub, Salon, and Audubon, and she's received the Red Hen Press Short Fiction Award, the Enizagam Short Story Award, and the Third Coast Fiction Prize. She's also the author of Red River Rising, an acclaimed account of the 1997 Grand Forks flood.If you like your climate fiction smart, satirical, and maybe a little too close to home, this one's for you.More info and past Climate Book Reviews episodes at: climatebookreviews.coSend us a text (if you'd like a response, please include your email)Produced by Amit Tandon & Bespoke Podcasts ___Energy vs Climate Podcastwww.energyvsclimate.com Contact us at info@energyvsclimate.com Bluesky | YouTube | LinkedIn | X/Twitter

In this edition of Plan Sea, host Anna Madlener sits down with co-host (and one of this week's guests) Wil Burns, Dr. Terre Satterfield from the University of British Columbia, and Dr. Chris Pearce from the UK's National Oceanography Center. Burns, Satterfield, and Pearce are some of the lead authors on a new  report launched at the 2025 UN Ocean Conference, “Principles for Responsible and Effective Marine CDR Development and Governance.”Commissioned by the High-Level Panel for a Sustainable Ocean Economy, the report outlines how to responsibly evaluate and potentially scale ocean-based carbon dioxide removal (oCDR) — also referred to as marine CDR — along three pillars: scientific and technological readiness, governance, and national implementation. The framework reflects months of collaborative research to help address how oCDR can begin to move from lab trials to real-world deployment — while maintaining high standards of scientific rigor, environmental protection, and public trust. Read the full report HERE.Dr. Terre Satterfield, Professor of Culture, Risk and the Environment at the University of British Columbia, joins Wil and Anna to discuss the report's recommendations for national strategies that can accelerate oCDR research and public engagement. She spoke about the importance of streamlining permitting processes for oCDR field trials, earmarking funding for lab networks for holistic oCDR evaluation, and investing in public engagement hubs to help co-design research efforts. Dr. Christopher Pearce, drawing from his research on oCDR science at the UK's National Oceanography Center, discusses how the report offers six categories to assess scientific and technological readiness for various oCDR approaches. This aims to help policymakers better understand when and why, for example, an approach may be quite well-understood by scientists in the lab, but the environmental impacts associated with larger projects are less understood and require field trials for further evaluation. He also explains how tools like pre-permitted testbed sites and national lab networks can promote data sharing and create the infrastructure needed for safe and scalable mCDR projects. Looking ahead, Wil, Terre, and Chris discuss how international frameworks like BBNJ (Biodiversity Beyond National Jurisdiction) can ensure accountability for future mCDR governance, and reflect on the major challenges facing the field—from limited public awareness and funding to the need for strong public oversight as the technology scales. The report offers important recommendations, such as creating pre-permitted testbed sites and national lab networks that can promote research efficiency and strong standards as oCDR continues to be evaluated, regulated, and tested. To learn more about the report's findings, listen to the full episode HERE, subscribe with your favorite podcast service, or find the entire series here. Plan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.ACRONYMS / CONCEPTS:MRV (1:26); Monitoring, Reporting, and VerificationTRL (6:58); Technology Readiness LevelSRL (6:44); Scientific Readiness LevelBBNJ (38:03); Agreement on Biodiversity of Areas Beyond National Jurisdiction, also known as tPlan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.

Send me a messageIn this episode of Climate Confident, I sat down with Kanika Chandaria, Climate Lead at Agreena, to explore one of the most overlooked yet high-impact climate solutions: soil.We talked about why regenerative agriculture is gaining traction, not just as a nature-based solution, but as a scalable, economically viable climate strategy. Kanika broke down how soil has the potential to sequester 2–5 gigatonnes of CO₂ annually, making it a key lever for companies aiming to meet net zero targets.We also got into the challenges: from the financial barriers facing farmers to the complexity of MRV (measurement, reporting, and verification) for soil carbon. Kanika explained how Agreena combines satellite imagery, AI, and selective soil sampling to deliver robust data at scale, data that's now being used not just for carbon markets, but to inform sustainable loans and supply chain initiatives.We examined the growing role of the private sector in climate action, especially as policy delays continue in the EU and US. And we discussed the importance of interoperability, why regenerative farming solutions need to work across carbon markets, food systems, and financial products.If you're a business leader thinking seriously about decarbonisation, soil carbon may be the high-impact tool you've been missing.

David & Ed chat with renowned scientist, author and Canadian, Dr. Katharine Hayhoe who argues that hope—not doom—is what drives action. Dr. Hayhoe is one of the world's most prominent climate communicators and known for crossing political, religious, and cultural lines to connect with audiences that most climate advocates can't or won't reach. It's an engaging discussion that delves into the psychology of despair, the limits of data in changing minds and behaviour, and whether hope still has a fighting chance. Show Notes:Available on the episode page on our website.About Our Guest:Katharine Hayhoe is an atmospheric scientist whose research focuses on understanding what climate change means for people and the places where we live.

In this edition of Plan Sea, hosts Anna Madlener and Wil Burns sit down with Kyla Westphal and Mallory Ringham from Ebb Carbon to discuss Project Macoma — the company's pilot ocean alkalinity enhancement (OAE) study being conducted in Port Angeles, Washington this summer. A first-of-its-kind endeavor, Project Macoma aims to remove up to 1,000 tonnes of  CO2 from the atmosphere using Ebb Carbon's electrochemical OAE technology. Kyla and Mallory join to share more about their journey engaging the local community on this proposed research, securing a permit from the U.S. Environmental Protection Agency (EPA), and establishing Monitoring, Reporting, and Verification (MRV) standards as this work gets underway. Project Macoma continues the work of the late Dr. Matthew Eisaman, Co-Founder of Ebb Carbon and a pivotal figure in the ocean-based carbon dioxide removal (oCDR) field. Matt dedicated his life to fostering a clear understanding of the scientific path forward for potential oCDR solutions, while also creating an inclusive and environmentally-responsible sector. For more background into Ebb Carbon and a deep dive into their approach, listen to our episode with Matt HERE. Kyla Westphal, Vice President of External Affairs at Ebb Carbon, joins Anna and Will to discuss her role developing safe and responsible deployment of OAE. Building on her experience working in what she calls “the intersection between technology and humanity,” Kyla oversees both the stakeholder engagement and ecological safety aspects of Ebb Carbon's work. She shares how Project Macoma is building on years of foundational environmental research and engagement with Washington state regulators, community groups, and tribal governments to earn local buy-in and support. Mallory Ringham, Lead Oceanographer and Head of MRV, then discusses how Ebb Carbon secured the first-ever National Pollutant Discharge Elimination System (NPDES) approval for oCDR under the Clean Water Act. She shares how the permit requires a slow, careful, and continuously monitored operation to ensure water quality standards are met within prescribed mixing zones. Mallory also discusses how Ebb's foundational research created a strong understanding of the seasonal and tidal variability in the region, allowing for more accurate monitoring and analysis of the project. This summer, Mallory will continue to oversee the monitoring process to ensure the project is operating safely, responsibly, and effectively.Plan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.ACRONYMS / CONCEPTS:MRV (1:05); Monitoring, Reporting and VerificationNPDES (14:56); National Pollutant Discharge Elimination SystemMCDR; Marine Carbon Dioxide Removal  (21:58)Plan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.

As the world confronts the urgent challenge of removing billions of tons of carbon dioxide from the atmosphere, breakthrough innovation is essential to scale solutions fast enough to meet global climate goals. On this episode of Earth911's Sustainability in Your Ear, discover the groundbreaking results of the $100 million XPRIZE Carbon Removal competition, a four-year competition among 1,300 teams from 88 countries that represents one of the most ambitious efforts to catalyze carbon removal innovation. We're joined by Nikki Batchelor, Executive Director of XPRIZE Carbon Removal, and Michael Leitch, Senior Technical Lead for the competition, to discuss what may be one of the most consequential moments in carbon removal innovation to date. They discuss how the competition's $100 million scope and multi-year timeline attracted breakthrough solutions and outline plans for continued engagement with the winning teams as they scale their innovations.[Kenya-based Mati Carbon claimed the $50 million grand prize with an enhanced rock weathering approach that spreads finely ground volcanic rock on farmland, simultaneously capturing atmospheric carbon while improving soil health for local farmers. Mati Carbon's victory wasn't just about technical innovation; it demonstrated a cost-effective approach that delivers multiple benefits in Kenya and India's smallholder farming communities. Three runners-up—NetZero, Vaulted Deep, and UNDO—each received $5 million for their distinct approaches, which spanned biochar production, underground carbon storage, and large-scale mineral spreading.In 2024 alone, humans released 41.6 billion tons of CO2 into the atmosphere, adding to approximately 1.5 trillion tons emitted since the Industrial Revolution. Current carbon removal projects operate at a kiloton scale and must rapidly expand to millions of tons annually. The goal isn't merely offsetting new emissions—it's achieving net-negative emissions to reverse the climate damage already done, albeit slowly.

In this edition of Plan Sea, host Anna Madlener is joined by Na'im Merchant, host of The Carbon Curve podcast and Executive Director of Carbon Removal Canada, for a special co-hosted episode of the two podcasts. Recorded live at the Carbon to Sea 2025 Annual Convening, Anna and Na'im speak with Lennart Bach, Associate Professor and ocean alkalinity enhancement (OAE) scientist at the University of Tasmania, to share insights and key takeaways from this year's convening.Last month, Carbon to Sea hosted its third Annual Convening in Washington, D.C., bringing together scientists, entrepreneurs, and policymakers to share recent progress and discuss a path forward for OAE. Bach, who previously spoke with Plan Sea on his work in ocean iron fertilization, was a speaker on this year's “Scientific Research Progress and Updates” panel. Focused on the environmental impacts of OAE, Bach's research aims to learn more about how OAE approaches may impact the marine ecosystem.Building on conversations from the convening, Bach joins Anna and Na'im to share his optimism about the future of OAE, while also recognizing the potential challenges posed by a dip in the “hype cycle” that emerging scientific fields often face. However, Bach said he feels confident in progress that's already been made and noted the importance of building on preliminary findings about OAE's potential to conduct more targeted research. Na'im similarly addresses this challenging moment for the climate industry writ large, as it faces reduced funding and policy support in many areas, with new geopolitical headwinds. Drawing on his experience working across the carbon removal space, Na'im offers advice for how the OAE field can address this moment by prioritizing focused research, establishing an updated roadmap, and exploring new funding pathways. Looking ahead, both Na'im and Bach highlight the importance of aligning on MRV approaches, cross-sector partnerships, increased community and policymaker engagement, and exploring new funding pathways in order to advance OAE research. As this year's convening exemplified, the immediate opportunities in OAE research have largely been addressed; what lies ahead is more complex and demands significantly greater coordination.Listen to our previous episode with Lennart Bach here.ACRONYMS / CONCEPTS: OAE (2:28)MRV (18:06)DAC (23:37)CRCF (29:59)ETS (29:59)ERW (36:16)Plan Sea is a semi-weekly podcast exploring ocean-based climate solutions, brought to you by the Carbon to Sea Initiative & the American University Institute for Responsible Carbon Removal.

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.

In this episode of our podcast, we dive deep into the transformative potential of Africa in the global shift towards a sustainable future, featuring an insightful conversation with James Mwangi, co-founder of Dahlberg and a leading advocate for innovative climate solutions in Kenya. We begin by discussing Africa's booming population and rich natural resources, which James argues position the continent as a powerhouse for innovation and leadership in the climate fight. Contrary to the narrative that views Africa as a victim of climate change, James emphasizes the continent's potential to lead, particularly through initiatives like the Great Carbon Valley, which aims to make Kenya a hub for carbon removals, including advanced technologies like direct air capture. Throughout our conversation, we explore several paradoxes that complicate the implementation of carbon markets. James introduces his own concepts, such as the "power illusion," which challenges the belief that blocking carbon removals will compel fossil fuel companies to reduce emissions. He also discusses the "mastery illusion," which suggests that expertise in climate solutions lies solely in the Global North, ignoring the talent and knowledge present in Africa. We delve into the work of the Climate Action Platform Africa (CAPE) and Africa Climate Ventures (ACV), two organizations James has founded to drive climate-positive growth in the region. CAPE focuses on identifying and realizing opportunities for sustainable development, while ACV invests in companies that address the climate crisis, showcasing innovative projects like biochar production and the Great Carbon Valley initiative. James shares the story of Safi Organics, a company utilizing rice husks to create biochar, which not only serves as a sustainable fertilizer but also contributes to carbon removal. We discuss the importance of transitional finance and the concept of additionality, emphasizing that carbon finance can catalyze projects that are already delivering value to communities. As we shift our focus to the Great Carbon Valley, James outlines Kenya's unique advantages, including its abundant renewable energy resources and geothermal potential. He argues that direct air capture can thrive in Kenya, leveraging the country's surplus energy to support industries that require significant power, ultimately benefiting local economies. We also touch on the recent developments in Kenya's carbon market regulations, which aim to create a competitive environment for carbon finance while prioritizing local benefits. James highlights the importance of building a market that is not only designed for Africa but also driven by local talent and innovation. In closing, we reflect on the need to reverse the brain drain and create opportunities for Africa's best and brightest to thrive at home. This episode is a powerful reminder of the potential for African leadership in the climate space and the importance of fostering local solutions to global challenges. Join us as we explore these critical issues and envision a sustainable future where Africa plays a central role.
