    107 | Mining's Untapped Removals Opportunity - with Cara Maesano

    In this episode of The Carbon Removal Scoop, Eve Tamme and Sebastian Manhart sit down with Cara Maesano, lead author of RMI's new report Mining and Carbon Dioxide Removal: A Responsible Path Forward, to dig into an industry the carbon removal world has barely talked about. Cara's starting point is striking: with the land, materials and engineering know-how that mines already have, almost every form of carbon removal could run on a mine site. But only one approach, she argues, really has to. Much of the conversation centres on surficial mineralisation, where reactive mine waste absorbs CO2 from the air and locks it away as stable minerals. Cara walks through the new research hub at Thetford Mines in Quebec, set up by Frontier and Carbon Removal Canada on a legacy of asbestos waste the local community wants gone, and explains how churning and activating tailings could push carbonation far deeper than the surface layer. She is clear that these are not cookie-cutter projects, and why. The hosts also press on the numbers. Cara is candid that the report's headline potential and $80 to $300 price range rest on theoretical and price-based estimates rather than hard cost data. On policy, she explains why permitting is a bigger hurdle than mining's vast footprint suggests: mines are permitted to do specific things with their waste and rarely deviate, which is why building carbon removal in from the very start of a mine's life may be easier than adding it later. They close on the business case. Thin profit margins per ton of CO2 mean miners are unlikely to buy durable removals, but they may have strong reasons to deliver them on site, from green premiums to tax credits to the environmental liabilities sitting in their tailings piles. Tune in to hear the one thing Cara says is holding the industry back.

    106 | SHOWDOWN: Europe’s CDR Strategy: BioCCS vs Tech Neutral - with Kaja Voss and Alastair Collier

    In this episode of The Carbon Removal Scoop, Eve Tamme moderates our fifth SHOWDOWN debate, live on stage at Carbon Unbound Europe in London. The motion takes on one of the hottest fault lines in European carbon removal policy: should Europe’s CDR strategy put BioCCS (biogenic carbon capture and storage) first? In the BioCCS corner, Kaja Voss, CEO and Founder of Inherit: an economist and believer in markets. Three-quarters of durable offtakes to date are already BioCCS, it sits lowest on the cost curve among high-durability solutions, and the pipelines and terminals it builds will serve other pathways later. Europe should pick that winner “on purpose rather than by accident.” In the tech neutrality corner, Alastair Collier, Chief R&D Officer at A Healthier Earth: “When you concentrate the technology, you concentrate the politics.” Pointing to Australia’s repeal of its carbon price, he warns that concentrating storage in a handful of member states and paying oil and gas companies to run it creates an easy target for climate sceptics. From Northern Lights and storage as a public utility to the CRCF (the EU’s Carbon Removals and Carbon Farming certification framework) and a closing call to look to China, the room had plenty to weigh before casting its vote. Listen to the end to find out who won.

    105 | What Next for the ISO Net Zero Standard - with Delia Meth-Cohn

    In this episode of The Carbon Removal Scoop, Eve Tamme sits down with Delia Meth-Cohn, Co-founder of Rethinking Removals, to make sense of what happened to ISO 14060, the draft net zero standard for organisations. When Delia joined Sebastian in June, the draft had just opened for consultation. Since then it has drawn around 5,000 comments and failed its first ballot, a rare result at this stage of an ISO process. Delia explains why this vote was different. Participation was capped at four experts per country because of the level of interest, few national standards bodies abstained, and the draft fell well short of ISO's thresholds of two-thirds approval with no more than a quarter of votes against. She walks through what comes next, a second draft and two more votes, and why publication now looks closer to 2028 than mid-2027. Eve and Delia dig into why the draft felt rushed, why an ISO standard carries quasi-regulatory weight that SBTi does not, and how the ground is shifting underneath it, with ISO and the GHG Protocol rewriting the foundations of carbon accounting. Delia's challenge for the next round is to treat the comments as themes rather than wording, and to find the balance between flexibility and credibility without watering the standard down. The conversation closes on removals. Speaking personally, Delia sets out how the next draft might handle anticipated residual emissions and the gap between cheap credits and expensive removals, and has a pointed message for a removals community she suggests needs to rethink its approach.

    104 | From Equity to Debt: How CDR Gets Bankable - with Julia Reichelstein and Tyler Manchester

    In this episode of The Carbon Removal Scoop, Sebastian Manhart sits down with Julia Reichelstein, co-founder and CEO of Vaulted Deep, and Tyler Manchester, Head of Voluntary Carbon at CFP Energy, to get the inside story of Vaulted's $35 million debt facility from Mediobanca. Julia explains why Vaulted grew on equity for its first two sites and why, with a delivery track record and a pipeline of new sites, it has now reached what she calls the "just add water" stage where debt is the right capital. Tyler explains why this is CFP Energy's first debt transaction in carbon removal after two decades in carbon markets, and what it took to get comfortable: a developer with a proven record, high-credit offtakers removing market risk, and an insurer covering the residual project risk that institutional lenders expect. He is open about who else can get through the door, including the rough minimum loan size CFP will consider, and why he thinks the market's chicken-and-egg problem is finally starting to crack. Julia makes the case that bankability starts long before anyone talks to a bank. She describes how the fine print of an offtake contract, the page she once skipped past, became the page lenders scrutinised most, and recounts the working capital fight that pushed registries and buyers towards monthly crediting. Both credit Frontier for brokering the introduction and publishing offtake templates others can reuse. They close on policy. Every debt deal discussed in the episode closed outside Europe, and Tyler sets out what would change that: projectable revenue, ideally fixed forward prices or a liquid forward market. Sebastian lays down a challenge for the first European deal, and Tyler accepts it.

    103 | Levelling up CDR Advocacy: Carbon Gap's Policy Levers Library - with Alexander Mäkelä

    In this episode of The Carbon Removal Scoop, Eve Tamme and Sebastian Manhart sit down with Alexander Mäkelä, Chief Policy Officer at Carbon Gap, to dig into the Policy Levers Library: a new living database of 165 policy levers across six policy families, unveiled at Carbon Gap's Carbon Removal Policy Summit in Brussels. Alex's starting point is blunt. The sector keeps reaching for the same few tools, contracts for difference, direct procurement, the EU ETS, and that may be a failure of imagination. Asked which lever Europe is leaving untouched, Alex lands on finance. Demand certainty dominates the conversation, but without bankability and capital ready to deploy, he argues, projects simply won't materialise. He makes the case for CDR debt that is as boring as renewables debt, and points to Stockholm Exergi's crowded capital stack as a sign of just how much it currently takes to get a BECCS project over the line. Eve and Sebastian also put the library itself under the microscope: why there is no impact score among its eleven criteria, how the team scored every lever using case studies from Europe, North America and the Global South, and where a policymaker handed the link should actually start. The hosts push for something the tool doesn't do yet, connecting policymakers with those who have already solved the same problem somewhere else. The conversation closes on advocacy, and why Alex thinks the sector is too reactive and too focused on Brussels when thousands of German municipalities alone have no plan for removals. Tune in to hear why Carbon Gap actively wants people to steal its work.

    102 | Inside the UK’s Answer to the GGR Review - with James Screen

    In this episode of The Carbon Removal Scoop, Eve Tamme and Sebastian Manhart sit down with James Screen, who until recently led the team designing carbon removal policy at the UK's Department for Energy Security and Net Zero. A year after the Scoop covered Alan Whitehead's independent review of greenhouse gas removals, James explains what the government's response actually is: not a grand strategy, but a staging post that sets out the UK's direction of travel and leaves the hardest questions for the Carbon Budget 7 delivery plan. James is candid in sharing his personal views about where the response parts ways with the review. He explains why there is little political appetite to reopen what net zero means by adopting geological net zero, the outlook on woodland in the UK ETS, and reads the new "as soon as practicable" timeline for removals in the UK ETS against the backdrop of possible UK and EU ETS linking. The conversation then turns to the GGR business models. James walks through how carbon contracts for difference sit on top of the network support model in clusters like Liverpool Bay, why he thinks the model can work for both voluntary and ETS sales, and why taxpayer subsidy cannot be the enduring answer. Sebastian and Eve also find themselves on opposite sides of whether the UK and Europe are making too narrow a bet on BioCCS and DAC. They close on the reshuffle that followed the response, with James explaining why he sees continuity rather than radical change, and why the story of solar and offshore wind gives him real cause for optimism.

    101 | Quarterly catch up: ETS Review, Buyers Coalition, and current VCM Dynamics

    In this quarterly catch up, Eve Tamme and Sebastian Manhart swap the guest chair for each other and look back at three busy months in carbon removal policy, with a few disagreements along the way. They start with the EU ETS review and the joint statement from Europe's five CDR associations, which Sebastian helped coordinate. He shares some of the background scoop on where the associations lined up and where they didn't, from biochar and the link to the Carbon Removal Certification Framework to whether international credits belong in the ETS at all. Eve draws on her experience of the last time international credits entered the system, and Sebastian previews his first academic paper on what a credible international credit portfolio might actually cost. Then comes the bigger question: is Europe putting all its eggs in the BioCCS basket, or is it six baskets? Sebastian worries that newer and potentially cheaper approaches are being left behind, while Eve makes the case for backing the projects that can deliver at scale now, and pushes back on the idea that all of Europe's CO2 is heading to the North Sea. They close with a reality check on the EU buyers coalition, where the usual optimist and sceptic swap roles, slow progress on durable removals under Article 6.4, and why the headlines out of New York Climate Week may not tell the whole story for carbon removal finance.

    100 | The Minister Betting Big on Biochar - with Minister Chi-ming Peng

    In this episode of The Carbon Removal Scoop, Eve Tamme and Sebastian Manhart sit down with Chi-ming Peng, Taiwan's Minister of Environment, shortly after he set a target that put Taiwan on the carbon removal map: one million tons of biochar carbon removal by 2030. A meteorologist and entrepreneur before he entered government, Minister Peng explains where the target came from, starting with a simple question to his team about who was responsible for biochar, and the discovery that nobody had yet submitted a carbon credit methodology for it. The pressure behind the target is hard to miss. Taiwan sits at the centre of the global AI supply chain, and its semiconductor giants will need carbon credits at a scale that expensive engineered removals cannot yet supply. With a carbon fee already in place and an emissions trading system on the way, Minister Peng makes the case that biochar is the pathway Taiwan can move on now, and explains why he is looking so closely at Europe's CRCF, the Buyers' Club and the EU ETS. Eve and Sebastian press him on the hard parts. Where will the feedstock come from, given five million tons of agricultural waste a year that mostly heads to incinerators? Why is importing more such a tough sell, with public resistance and the Basel Convention in the way? And how does a country that cannot attend COP as a party still plan to trade carbon credits under Article 6.2, with Paraguay first in line? They close on the next six to twelve months: the machines, the money, and the methodology still to be locked down before Taiwan's number can move from ambition to actual credits. Whether biochar becomes part of Taiwan's answer to a semiconductor industry's carbon problem, or another target that outruns the paperwork, is the question worth watching from here.
