EU ETS review opens door to CDR — advocate calls it 'the best birthday present

Carbon Herald just published Opinion: The EU Sent Me A Birthday Present. Carbon Herald has published an opinion piece reacting to the European Commission’s ETS review, released on 17 July - which happened to be the author’s birthday. According to the piece, the review proposes moves that would position the EU as the largest driver of demand for carbon removals, a step the author reads as a turning point for the CDR sector in Europe. The commentary frames the announcement as long-awaited recognition that permanent removals need a regulated compliance market to scale, and situates it within the broader debate over integrating CDR into the EU Emissions Trading System. ...

Captain's CDR Log #210: Five numbers that show which CDR pathways are getting paid and which are still getting peer-reviewed

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Five numbers crossed my desk this week, and lined up side by side they show carbon removal’s pathways splitting along a single fault line: settled measurement gets capital, contested measurement gets peer review. The comparison is not decorative. It is the whole story. $500M+ is what Eni CCUS Holding closed this week (Carbon Herald) to fund European carbon capture and storage growth. Note who got it: a fossil-major spinout, not a pure-play removal startup. One framing caution is mandatory here. Capture attached to fossil infrastructure addresses point-source emissions and is never a license to delay phase-out; removal budgets exist for hard-to-abate residuals only. But the capital signal stands: investors will write nine-figure checks where the storage regulation and the measurement stack are mature. ...

Biochar keeps 7,091 active researchers as dormant floor deepens

This chart tracks Biochar researchers over time on a diverging axis. Above the line are researchers who published a Biochar-relevant paper that year (active); below the line are dormant researchers, split into those who published the previous year and those who published only earlier. New entrants join at the base of the active band each year as a teal block. Biochar is a large, agronomy-adjacent field with a deep pool of one-time contributors. The top envelope is the number actually publishing in the pathway each year. ...

Captain's CDR Log #209: Maxbauer's Midwest trial says the basalt emperor may be wearing very little

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. 1. The story A field trial on CDRXIV lands a direct hit on enhanced rock weathering’s favorite mineral. Daniel Maxbauer and colleagues spread crushed rock on a midwestern U.S. cornfield and measured what happened. Their result: coarse-grained basalt produced no statistically detectable CO2 removal signal, while steel slag did, and even the slag signal appeared only on soil that started out acidic. Slag on near-neutral soil showed nothing significant either. Basalt is the feedstock most ERW startups are selling and most buyers are underwriting. A null result on that mineral, in the heart of U.S. row-crop agriculture, deserves more attention than it will probably get. ...

Captain's CDR Log #208: Rebecca Neumann traced the 10 Gt number and found no there there

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The consensus is simple and everywhere: the world needs roughly 10 gigatonnes of durable carbon removal per year by 2050, and that number comes straight from the science of the Paris temperature targets. Buyers size their portfolios against it. Startups pitch against it. Policy-facing writing treats “closing the gap to 10 Gt” as the sector’s organizing problem, as in this Open Access Government piece on closing the carbon dioxide removal gap, which is a fair sample of how the framing gets deployed downstream. ...

Week in CDR — 2026-W30

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. ...

Carbon Credit Prices Track Buyer Preferences, Not Climate Impact: MIT Study

Carbon Herald just published MIT Study Finds Carbon Credit Prices Reflect Buyers’ Preferences Far More Than Climate Impact. Carbon Herald reports on new MIT research examining how credits are priced in the voluntary carbon market. According to the study, prices are shaped far more by buyer characteristics and preferences than by measurable climate impact, meaning two credits with similar mitigation value can trade at very different levels depending on who is purchasing them. The finding challenges the assumption that market prices act as a reliable signal of quality or additionality in the VCM. It also adds academic weight to ongoing concerns that the market rewards branding and buyer optics over verified emissions outcomes. The full article covers the study’s framing and what it implies for market reform. ...

Captain's CDR Log #207: Rivers may be eating the alkalinity ERW models assume reaches the sea

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The critique “This is indeed one of the reasons why I think there is still a justification for the old practice of seeing CDR as a form of geoengineering. They both decouple climate variables from cumulative emissions.” That’s Oliver Morton (@eaterofsun on Bluesky), and the target is any CDR pathway whose mass balance does not cleanly close. Enhanced rock weathering (ERW), where crushed silicates dissolve in soil and the resulting alkalinity is assumed to travel to the ocean for long-term storage, is exactly that kind of pathway right now. ...

Captain's CDR Log #206: Peter Reinhardt's bet that crop residue and wildfire fuel are the same operator problem

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Peter Reinhardt just spent two hours on the record explaining how to turn crop residue into carbon buried a kilometer underground. On Heatmap’s Shift Key podcast, What Barbecue Sauce Has in Common With Carbon Removal, the Charm Industrial CEO walked through the company’s full pipeline: gather waste biomass, pyrolyze it into a thick bio-oil, then inject that oil into deep geological formations where it stays. It is the most detailed operator interview any durable CDR chief executive has given this quarter, and it reads less like a pitch than a plant tour. ...

CDR Daily Digest — 2026-07-24

CDR’s demand problem got attacked from three directions today, and that is the pattern worth noticing. The European Commission proposed putting 250 million tonnes of permanent carbon removal into its compliance market. J.P. Morgan extended debt financing to Charm Industrial. And SBTi’s rulebook, which refuses to let removals stand in for emission cuts, came into focus as the single biggest brake on corporate buying. Compliance demand, bank debt, and voluntary-market rules all moved or mattered on the same day. The industry’s binding constraint has never been capture chemistry. It is who pays, under what rules, and today the answers got sharper. ...
