When the biggest buyer leaves the room Microsoft has paused new CDR purchases. That single move pulls roughly 90% of demand out of the voluntary carbon removal market. Today’s other stories make more sense once you hold that fact in your head: a market that grew up around one buyer is now being asked to grow up, fast. The demand shock Microsoft’s pause is not a minor reshuffling. The company has been the anchor buyer for durable removals across DAC, biomass with carbon capture and storage (BECCS), enhanced rock weathering (ERW), and marine pathways. Suppliers built roadmaps around its offtakes. With those new contracts on hold, every developer with a 2027 or 2028 delivery date is now reworking their financing assumptions. ...

Capture6 just crossed a threshold that most DAC startups haven’t: project financing for a second phase. That detail matters more than the press release suggests, because it tells you which part of the DAC stack is starting to work, and which part is still stuck. The headline: project finance is showing up for Phase 2, not first-of-a-kind Capture6 secured project financing to build out Phase 2 of its Monarch DAC facility. Most direct air capture deployments to date have been funded by a mix of equity, grants, and advance market commitments from buyers like Frontier or the US Department of Energy’s DAC Hubs program. Project finance, the kind of debt that funds pipelines, solar farms, and water treatment plants, has been almost absent from DAC. ...

Today’s thread is about plumbing. Not announcements, not moonshots. The pipes and ledgers that decide whether a ton of CO2 removed actually counts as a ton. Four of today’s five stories are about the scaffolding under CDR: a new biochar methodology from Gold Standard, a leadership change at the biggest mineralization player, Japan opening seabed for CO2 storage, and a reef-linked biochar partnership in Australia. The fifth, the Captain’s Log, argues the old carbon accounting layer is cracking and a parallel trust stack is being built to replace it. Read together, the day is less about new technology and more about who gets to certify, operate, and store removals at scale. ...

Today’s three stories share a single thread: carbon removal and storage is crossing from slide decks into steel. Pipe bridges are being hoisted, offshore wells are taking CO2, and a third purpose-built ship is joining a cross-border fleet. The bottleneck is shifting from “can we build it” to “can we connect the pieces fast enough.” Infrastructure is the story now Stockholm Exergi lifted a pipe bridge roughly the length of a football field into place this week at its Värtan site, a visible milestone for the 720,000 ton per year bioenergy carbon capture project. Bioenergy with carbon capture and storage, or BECCS, pulls CO2 out of biomass flue gas and ships it to permanent storage. The project is one of the largest BECCS builds in the world and is backed by a Swedish reverse auction contract plus a Microsoft offtake deal for multi-million tons over ten years. ...

Today’s three stories share one uncomfortable thread: the accounting rules that CDR markets depend on are being rewritten in real time, and a lot of what counts as “removal” today will not count tomorrow. The MRV reckoning is here CarbonPlan’s review of Lithos Carbon, published this week, is the clearest sign yet that enhanced rock weathering (spreading crushed basalt on fields to pull CO2 from the air) is running ahead of its measurement science. The review questions how Lithos models cation loss, how it handles soil sampling variance, and whether current protocols can distinguish a real removal signal from background noise. This matters because Lithos has been one of the better-funded ERW suppliers, with Frontier among its buyers. If the critique lands, every ERW developer will face tougher questions from buyers about measurement, reporting, and verification — the MRV stack that turns a field trial into a tonne you can sell. ...

Biochar spent most of the last decade as a cottage industry. Hundreds of small producers, bespoke feedstocks, regional offtake deals, a long tail of sub-10,000 tonne projects. Today’s story is about what happens when that phase ends. Consolidation is now the defining pattern in biochar, and it is arriving faster than most CDR watchers expected. From artisan to industrial The tell is in the deal flow. Larger producers are absorbing smaller ones, platform companies are rolling up regional operators, and strategic buyers from forestry, agriculture, and waste management are taking equity stakes in pure-play biochar firms. The logic is straightforward. Biochar’s unit economics depend on three things: cheap and consistent biomass, high utilization of pyrolysis capacity, and access to durable offtake contracts. None of those three reward fragmentation. ...

The week CDR stopped being graded only on tons Something shifted this week. Three separate stories, from three different corners of the field, all pointed at the same question: what counts as a good ton of carbon removal? For two years the answer has been “a cheap one that verifies.” This week that answer started to break. The money is moving, but not where the headlines suggest The Captain’s Log tracked five numbers from the past seven days. The pattern underneath them is what matters. Capital is still flowing into CDR, but it is flowing toward projects that can prove durability and clean supply chains, not just low price per ton. Buyers who spent 2024 chasing the cheapest verified credit are now asking harder questions about what happens in year 40, where the energy comes from, and who lives near the project. ...

The Day CDR Started Writing Its Own Rulebook Today’s four stories point at one pattern: the CDR field is no longer waiting for governments to define what counts as good carbon removal. Buyers, nonprofits, and companies are writing the rules in real time, and the definitions they pick now will shape which projects get funded for the next decade. That is the headline. The rulebook is being drafted in public, by the people placing the bets. ...

Today’s signal is a widening split in carbon markets. Engineered removals are posting record volumes and long-term contracts, while a major avoided-emissions category just got downgraded by an order of magnitude. Buyers are voting with their checkbooks, and the vote is for durable, measurable tons. The record month nobody should gloss over March 2026 logged 1.51 million tonnes of CDR purchases in a single month. That is not a cumulative figure. It is one month. The pace suggests 2026 will blow past every prior year, and the mix is shifting toward contracts with real delivery schedules rather than speculative forward offtakes. The buyers driving this are familiar names, but the volumes per deal are climbing. ...

The gap between carbon credit claims and real-world carbon removal just got another data point. A new study finds that REDD+ avoided-deforestation projects overclaimed their climate benefit by a factor of 10.7. Meanwhile, buyers and developers are shifting toward removal credits with tighter measurement, and the signals are everywhere in today’s stories. The crediting gap is reshaping where money flows A peer-reviewed study found that REDD+ projects, which sell credits based on forests they claim would have been cut down, overstated their avoided deforestation by 10.7 times on average. That means for every ton of CO2 these credits claimed to protect, roughly a tenth of a ton was real. This isn’t new territory. Earlier analyses flagged similar problems. But the scale of the overclaim keeps getting confirmed, and it matters because these credits still circulate in voluntary markets. ...
