Captain Drawdown’s weekly Sunday selection — 48 candidate stories considered, 6-9 picked. Each link carries our 1-2 sentence take so you don’t have to click everything to know what’s there.
The week’s most useful signal came from a five-year scorecard on whether durable CDR has lived up to its 2021 promises — and the answer, predictably, is “uneven.” Around it, mineralization quietly emerged as the pathway with the most institutional momentum (Frontier, Carbon Direct, Arca, a new Quebec hub), while buyer-side activity continued to broaden beyond DAC into biochar and enhanced rock weathering (ERW) portfolios. Meanwhile Europe is sending mixed signals on carbon markets: Germany retiring allowances, IEEFA pushing back on power-sector CCS, and the EU inching toward letting international removals back in.
Reality check at year five
- CDR.fyi Blog — Durable CDR: Reality vs Expectations — A useful corrective to the 2021 hype cycle: CDR.fyi grades pathways on permanence, scale, measurement, reporting, and verification (MRV) and cost, and the headline is that biochar and ERW have outperformed expectations on deployment while DAC has lagged on cost curves. Worth reading before your next pathway allocation discussion.
- Captain Drawdown — 570 pure-play CDR startups employ just 9,498 people combined — A sobering scale check: the entire pure-play CDR workforce is smaller than a single mid-size oil refinery’s headcount. If gigatonne ambitions are real, the talent pipeline is two orders of magnitude short.
Mineralization gets its institutional moment
- Carbon Herald — Frontier And Carbon Removal Canada Launch The World’s First Surficial Mineralization Hub — Quebec’s asbestos and mining tailings legacy gets reframed as a feedstock advantage; Frontier’s involvement signals that surficial mineralization is graduating from lab curiosity to a buyer-backed deployment category alongside DAC and ERW.
- Carbon Herald — Arca And Carbon Direct Team Up On Scaling Industrial Mineralization — Carbon Direct’s MRV credibility paired with Arca’s mine-tailings tech is the kind of standards-plus-supply pairing the pathway needs to attract corporate buyers wary of methodology risk.
- Captain Drawdown — Co-reactive switches on CO₂-to-construction-materials demo plant — German entrant joins a crowded ex-situ mineralization field (Heirloom, CarbonCure, Neustark), but the continuous-process angle on industrial mineral waste is the differentiator to watch.
Buyer side keeps broadening
- One Stop ESG — Boeing Buys 20,000 Tonne Biochar and ERW Portfolio Through Supercritical — Aviation buyers continuing to diversify beyond SAF-adjacent removals; the 20kt portfolio split across biochar and ERW reads as a deliberate hedge against any single methodology getting downgraded.
- Carbon Herald — Carbonaires Launches Offtake-Backed Financing RFP — The financing-layer gap between letters of intent and FID is where most CDR projects die; an offtake-backed structured product targeting that gap is more interesting than another spot-purchase announcement.
Europe’s carbon market crosscurrents
- Carbon Herald — Germany To Pull Carbon Credits Freed By 2024 Coal Phaseout From EU Market — Voluntary cancellation tightens EU ETS supply and is the clearest signal yet that Berlin wants the carbon price higher — relevant for any CDR economics modeled against EU compliance prices.
- Carbon Herald — IEEFA Warns EU Against Costly Bet On CCS In Power Sector — The think-tank case that gas-plus-CCS is a stranded-asset trap matters for CDR because every euro that flows to power-sector CCS is a euro not flowing to removals — and the lobbying battle for the EU industrial decarbonization budget is now active.
- DVNE — International Removal Credits for the EU — The reopening of the international-credits debate inside EU climate policy is the file to watch this year; if removals get a carve-out under Article 6-style flows, it changes the addressable market for non-EU CDR suppliers materially.
Notable absence this week: no major DAC announcements, no new US policy news of substance, and remarkably little from the methodology bodies despite GHG Protocol naming its first CEO. The center of gravity is visibly shifting toward mineralization and toward European policy mechanics — and away from the DAC-dominated narrative that defined 2023-2024.
