Rock Flour Company just secured €1.6 million from INNO-CCUS to launch Project ICEFIELD, what will become Denmark’s first certified enhanced rock weathering (ERW) credit pathway. The project uses rock flour sourced from Greenland and will run field pilots ranging from small research plots to full commercial-scale fields across Denmark. Why it matters ERW is one of the more promising CDR approaches because it can work alongside existing agriculture. Farmers spread finely crushed rock on their fields, the minerals react with CO₂ in the soil, and the carbon gets locked away in dissolved form. But the pathway from “promising science” to verified, sellable carbon credits has been a persistent bottleneck. Denmark has had no certified ERW credit system until now. If ICEFIELD delivers, it creates a template that other European countries could follow. ...

Verra, the world’s largest carbon credit standard-setter, has released updated guidance for projects seeking Article 6 and CORSIA labels on their carbon credits, along with a new tool designed to help buyers figure out which credits qualify for compliance-grade use. The move signals that the voluntary carbon market’s infrastructure is steadily being rebuilt around the needs of regulated buyers, not just voluntary ones. Why it matters Two of the biggest demand signals for carbon credits in the coming decade are Article 6 of the Paris Agreement, which governs international carbon trading between countries, and CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation. Both create compliance-level demand, meaning airlines and governments will need credits that meet strict eligibility rules. For CDR project developers, understanding whether their credits can carry these labels is the difference between selling into a niche voluntary market and accessing potentially massive regulated demand pools. ...

Germany will need to remove 39 to 51 million tonnes of CO₂ per year by 2045 to hit its climate-neutrality target, according to a new study from Fraunhofer ISE, one of Europe’s leading energy research institutes. And the study delivers a blunt warning: delays in building out CO₂ transport and storage infrastructure significantly raise the risk of missing those targets entirely. Why it matters This is one of the first major studies to model CDR ramp-up within the full context of Germany’s energy system, rather than treating carbon removal as a standalone exercise. That distinction is important. CDR technologies need biomass, renewable electricity, and pipelines to move captured CO₂. Modeling them in isolation misses the bottlenecks. Fraunhofer ISE’s work makes those dependencies explicit, and the numbers are large enough to demand serious infrastructure planning starting now. ...

The EPA has issued its first Class VI underground injection permit in Kansas, granted to PureField Carbon. This expands the map of where permitted CO2 storage can happen in the United States, adding another state to a still-short list of locations with federal approval for dedicated geological sequestration. Why it matters Class VI permits are the regulatory gatekeepers for underground CO2 storage in the US. Without one, you can’t legally inject CO2 into deep geological formations for long-term sequestration. Every new permit issued, and every new state added to the permitted geography, matters because the entire CDR and carbon capture pipeline depends on having somewhere to put the CO2 once you’ve captured it. Storage permitting has been one of the biggest bottlenecks in the sector, and Kansas joining the roster of states with approved Class VI wells is a meaningful step. ...

ZEN Carbon has moved from pilot stage to live industrial deployment by partnering with Flamingo Concrete, a ready-mix concrete supplier in Kenya, to embed CO₂ mineralization directly into concrete production. It’s a small but meaningful proof point: carbon removal integrated into one of the most widely used building materials on the planet, operating inside a real production facility rather than a lab. Why it matters Concrete is everywhere. It’s the second most consumed material on Earth after water, and its production is responsible for roughly 8% of global CO₂ emissions. Most decarbonization efforts in this sector focus upstream, on making cement with fewer emissions. ZEN Carbon is taking a different angle: mineralizing CO₂ during the concrete mixing process itself, turning the finished product into a permanent carbon sink. If the approach works at scale, it could turn buildings and infrastructure from emission sources into storage. ...

The Negative Emissions Platform (NEP) wants the EU to spend €1 billion starting in 2026 on a pilot purchasing programme for permanent CDR, built around an “EU Buyers’ Club” that would pool demand from mid-sized companies and pay per-tonne subsidies only when removal is verified. The proposal is designed to bridge the gap between now and whenever permanent CDR gets folded into the EU Emissions Trading System (ETS), the bloc’s main carbon pricing mechanism. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The CDR sector is panicking about losing its biggest patron. But the infrastructure to make that patron optional is being built right now, in parallel, and mostly being ignored. Microsoft has paused new carbon removal purchases. The reaction across the CDR community has been swift and anxious. As James Temple put it: “MSFT is the carbon removal market, so if this is anything more than a brief pause, it’s a v. big deal & v. bad news for an already shaky sector.” He’s right. Microsoft’s outsized role as buyer, signal-sender, and de facto market-maker means this pause sends shockwaves far beyond Redmond. Dirk Paessler noted that the CDR community immediately treated the news as an industry-wide crisis. Even Biochar Today flagged the Microsoft story, which is telling. Biochar has arguably the strongest standalone economics of any CDR pathway. If even that community feels the need to sound the alarm over a single corporate buyer stepping back, it reveals just how deeply the voluntary patronage model has colonized CDR’s collective psychology. ...

When your anchor buyer disappears, what keeps a CDR company alive? That question ran through several of today’s stories, and the answer is converging on a single theme: the projects that survive will be the ones that deliver value beyond the carbon credit. Co-benefits as survival strategy Captain’s CDR Log #102 makes the case plainly. When a major buyer walks away, a CDR project built solely around selling tonnes of CO₂ removal is exposed. But projects that also deliver clean energy, soil health, water quality, or local jobs have fallback revenue and political support. Co-benefits are not marketing fluff. They are financial resilience. In a market where voluntary demand is still fragile and compliance frameworks are still forming, the ability to point to tangible local value can mean the difference between a project that weathers a downturn and one that folds. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The CDR industry doesn’t have a demand problem. It has a customer concentration problem. And Microsoft just made that painfully clear. Robinson Meyer broke the news this week: Microsoft Is Pausing Carbon Removal Purchases, with the tech giant accounting for more than 90% of industry volume last year. Read that number again. More than ninety percent. When one buyer represents that much of your total market, you don’t have a market. You have a dependency. James Temple put it plainly: “MSFT is the carbon removal market, so if this is anything more than a brief pause, it’s a v. big deal & v. bad news for an already shaky sector.” - James Temple (@jtemple.bsky.social) ...

Denmark’s early moves on carbon removal policy offer a cautionary tale for the UK: ambition without matching technological readiness leads to misaligned targets and wasted momentum. That’s the core argument from Leonie Meissner at LSE’s Grantham Research Institute on Climate Change and the Environment, who uses Denmark’s experience to warn that the UK needs to calibrate its net zero strategy more carefully. Why it matters The UK government has baked CDR into its net zero 2050 plans. So have most major economies. But there’s a difference between penciling in millions of tonnes of future carbon removal on a spreadsheet and actually having the technology, infrastructure, and policy frameworks ready to deliver it. Denmark got out ahead on CDR policy, and the lessons from that experience, both good and bad, are directly relevant to the UK as it shapes its own approach. ...
