Captain Drawdown’s weekly Sunday selection — 9 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 candidate pool this week skews academic, with five research artefacts against two industry items. That makes for a cleaner-than-usual read on where the methodological frontier sits: ocean CDR efficiency, carbon-cycle asymmetries under net-negative pathways, and the discourse layer sitting on top of it all. On the commercial side, Climeworks is the only operator making noise. ...

Captain Drawdown’s weekly Sunday selection — 8 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 signal is concentrated on enhanced rock weathering, with two peer-reviewed papers pulling in opposite directions on whether ERW can actually deliver at scale, alongside a commercial deal extending ERW credit access. Around that core, offshore CCS gains a new contractor entrant and mineralization-in-concrete gets a fresh LCA scrutiny. ...

Captain Drawdown’s weekly Sunday selection — 11 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 throughline is credibility infrastructure: German regulators pulling credits from Chinese projects, a long-running CDR newsletter reassessing its own cadence, and researchers modeling what a real CO2 transport backbone would need to look like. Deal flow continued in the background, but the more interesting signal is around what gets counted, trusted, and physically moved. ...

Captain Drawdown’s weekly Sunday selection — 14 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 through-line this week is a demand-side wobble meeting a conceptual reckoning: Microsoft’s pullback lands at the same time researchers and commentators are picking apart how removals should count against emissions in the first place. Meanwhile, the supply side keeps announcing pilots and offtakes as if nothing had changed. ...

Captain Drawdown’s weekly Sunday selection — 16 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. Two structural stories dominated the week: fresh evidence that natural carbon sinks are getting less reliable exactly when we need them most, and concrete signals about how the CDR market plumbing — pipelines, ETS integration, procurement readiness — will actually get built. Below, the science pieces that should update your baselines, and the market-infrastructure pieces that should update your roadmaps. ...

Captain Drawdown’s weekly Sunday selection — 15 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 connecting thread this week is accountability — who checks the numbers, and what happens when they don’t hold. Two governments faced scrutiny over how removal money and removal policy actually get executed, two registries and frameworks opened up their accounting logic for inspection, and a stack of new bench science quietly explained why several pathways are slower or messier than the pitch decks suggest. If you only have ten minutes, read the policy pair; if you’re building or buying, the methodology cluster is where the money will move. ...

Captain Drawdown’s weekly Sunday selection — 15 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 split cleanly along the industry’s two workstreams: cleaning up how credits are defined and issued, and grinding out the operational evidence for the removal pathways themselves. Verra’s cookstove overhaul and a new Nature framework both attack the classification chaos that keeps burning buyers, while on the deployment side, DAC and BECCS projects in Europe put actual cost and tonnage numbers on the table. Enhanced rock weathering, meanwhile, is quietly assembling the field-data record it will need when scrutiny inevitably shifts its way. ...

Captain Drawdown’s weekly Sunday selection — 16 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 connecting thread is infrastructure and institutions catching up to the pitch decks: Canada committing real money to a west-coast CO2 pipeline, the Netherlands naming a CRCF supervisor, Germany opening its largest DAC unit, and a fresh arXiv paper reminding us that enhanced weathering timelines depend on soil chemistry the marketing rarely mentions. Meanwhile the buyer base for durable CDR keeps broadening even as the EU ETS review slips — small delay, but the calendar around 2040 targets is tightening. ...

The week’s signal sits at the intersection of policy plumbing and capital flows: jurisdictions are linking compliance markets while private registries and ocean-CDR vendors raise rounds that bet on those markets actually clearing. Meanwhile, the methodology frontier keeps creeping into stranger biology — fungi-mediated soil carbon credits being the latest test of what measurement, reporting, and verification (MRV) can credibly underwrite. ...

Captain Drawdown’s weekly Sunday selection — 13 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 signal is a widening gap between announced capacity and what’s actually getting built or bought. A 1Mt ARR deal and the largest-ever SAF certificate purchase show corporates still willing to write big checks for the lower-permanence end of the stack, while a new UK DAC consortium and fresh analyses of the EU Buyers’ Club and marine CDR rulebook underline how much policy scaffolding is still missing for the durable end. A German broadsheet hammering the “huge gap” framing rounds out the mood. ...
