Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all.
Five numbers from the past week tell one story: the accounting layer under voluntary carbon markets is cracking, and a replacement stack is being poured underneath in plain sight. Legacy standards are leaking whistleblowers and disqualifications. Newer registries are quietly shipping durable tonnes.
80,000 credits — BCarbon issued 80,000 verified CDR credits from Carbon Rho’s Red River biomass burial project (Carbon Herald). A nonprofit registry most corporate buyers couldn’t have named a year ago is now shipping durable tonnes. Verra and Gold Standard issued nothing of the kind this week.
~100% — New EU draft rules could disqualify almost all existing CORSIA Phase 1 credits for European airlines (Carbon Herald). CORSIA is the aviation sector’s compliance mechanism, the buyer of last resort for legacy offsets. When that backstop rejects essentially the entire available supply, the “offset” category itself is being repriced toward zero.
60+ companies — More than sixty corporates, including Apple, Amazon, GM and FedEx, are lobbying the GHG Protocol to weaken Scope 2 reporting rules (Bloomberg). Scope 2 covers emissions from purchased electricity. Google and Microsoft are notably absent from the letter. The split matters: the largest durable-CDR buyers are not fighting to keep the rulebook loose.
1 whistleblower report — Emily Pontecorvo’s Heatmap reporting landed the week’s most underweighted CDR story. “Scientists have deep concerns about one of the world’s leading climate standards-setting groups, the Greenhouse Gas Protocol. A new whistleblower report raises serious questions about the group’s transparency and governance.” - Emily Pontecorvo (@emilypont.bsky.social). The GHG Protocol sits underneath every corporate net-zero claim. A governance failure here cascades into every voluntary credit downstream, including CDR offtakes that rely on Scope 1/3 accounting to justify the purchase.
1st country — Switzerland became the first country to include industrial CDR in its national greenhouse gas inventory (Carbon Herald), filed under its 2024 UNFCCC submission. While corporate accounting devolves into lobbying fights, sovereign accounting is moving to a higher standard of rigor than the voluntary market. National inventories get audited by the UN. Corporate disclosures get audited by whoever the CFO hires.
The pattern
These five numbers are not separate stories. They are one story told from five angles. The legacy stack (GHG Protocol, CORSIA-eligible credits, Verra-era offsets) is losing credibility from the top through whistleblowers and regulator disqualifications, and from the bottom through corporate lobbying to soften the rules. Meanwhile a parallel stack (BCarbon, Isometric, sovereign inventories, project-level durable issuances) is already processing the flows that matter.
The uncomfortable implication for developers: the question is no longer “which legacy registry will approve my methodology.” It is “which accounting rail will still be credible in 2028.” Buyers chasing defensibility are already voting with their contracts, routing offtakes through durability-graded registries rather than through the CORSIA pipeline. Our earlier note on Mombak’s first Isometric-verified enhanced weathering credits fits the same pattern: the tonnes moving at premium prices are the ones on rails that can survive a whistleblower report.
Watch the GHG Protocol’s next consultation round. If it addresses the governance complaints head-on, the voluntary market gets a reprieve. If it papers them over, expect a breakaway: Microsoft, Google and a cluster of durable-CDR-aligned buyers defining their own Scope 2/3 floor outside the Protocol entirely. Either way, the developers staffed for rulebook risk six months ago are the ones closing deals now. The ones still arguing about footnotes are not.
One last thing worth naming plainly: none of this is a license to slow fossil phase-out. CDR is for residual emissions. A cleaner accounting stack only matters if the tonnes underneath it are real, durable, and additional to decarbonization, not a substitute for it.
