Swiss wastewater body tenders biogas upgrade; Carbon Herald calls it a Europe trend
Carbon Herald just published Swiss Biomethane Tender Highlights European Shift Toward Biogenic Carbon Capture. Carbon Herald reports that EBBV, an intermunicipal wastewater association serving the Basse-Broye and Vully area of Switzerland, has opened a public procurement process for a complete biogas upgrading facility. The plant would separate methane from the raw biogas produced during sewage sludge digestion so it can be injected as biomethane, with the CO2 fraction becoming a potential feedstock for capture rather than a vent stream. The outlet frames the tender as one example of a broader trend among European utilities and waste operators to treat biogenic CO2 from anaerobic digestion as a resource for storage or utilization. The piece does not give a project budget, timeline, or confirmed capture volume, and the tender itself appears to cover upgrading rather than a dedicated capture unit. ...
Captain's CDR Log #282: Buyers are lining up, but few projects get through the diligence gate
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 that durable carbon removal is demand-limited. Buyers, advocates, and most market commentary repeat it. Kevin Lee Caster (@kevinleecaster.bsky.social on Bluesky) puts it in one line: “Millions of tonnes of Carbon Dioxide Removal are being purchased. Millions more tonnes of CDR need to be purchased in order to help the industry grow to the scale necessary.” More tonnes bought, more plants built. That is the model. ...
CDR Daily Digest — 2026-10-08
All four of today’s stories come down to one question: which tonnes count. The physical limits on carbon removal are not the binding constraint right now. The accounting rules are. That shows up in the EU, where a plan for 250 Mt of removals inside the Emissions Trading System depends entirely on eligibility definitions. It shows up in the UK, where the government’s answer to its greenhouse gas removal (GGR) review is mostly a set of rules about what qualifies for support. It shows up in the science, where the honest answer to “how much can enhanced rock weathering remove” is “it depends on what you can measure.” And it shows up in Klaus Lackner’s long-running argument that scale is a manufacturing and policy problem, not a chemistry problem. The ceiling on CDR this decade is a definitions problem. ...
Captain's CDR Log #281: The EU ETS plan for 250 Mt of removals hinges on which tonnes count
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The 250 Mt figure settles how much, not which tonnes or whether they arrive Carbon Gap’s explainer on the EU Emissions Trading System (ETS) puts a single number in front of European removal suppliers: the European Commission plans to fund 250 million tonnes of carbon removal through the ETS by 2040 (Carbon Gap on LinkedIn). The plan itself traces back to the Commission’s July legislative proposal for the ETS review, so the volume is not new. What Carbon Gap adds is the framing. The post says the rules now have to answer two questions: will they make sure the removals happen, and which removals will count (same post). I think that framing is right, and it changes how suppliers should read the number. 250 Mt is a ceiling on possible demand. It is not a commitment to any method. ...
Google deal pushes September 2026 durable CDR past 1M tonnes — but it's lumpy
CDR.fyi just published Durable CDR Market Recap: September 2026 — Key Deals & Trends. CDR.fyi’s monthly recap reports that more than 1 million tonnes of durable carbon removal were contracted in September 2026. The bulk comes from Google’s agreement with enhanced weathering developer Terradot for 1 million tonnes, paired with a separate 1 million tonne CO2e methane elimination purchase by 2030. Smaller deals include Granitor buying 5,000 tonnes from Stockholm Exergi for delivery starting in 2030, Milkywire closing eight Salesforce-backed pre-purchases totalling 3,661 tonnes across DAC, alkalinity enhancement and biomass storage, and Japan Airlines signing a CORSIA-oriented agreement with Climeworks. The partnerships section covers Exomad Green and Carbonfuture expanding biochar supply by 1.1 million tonnes through 2035, Whirlpool’s multi-supplier portfolio via ClimeFi, Supercritical’s India distribution deal with Ground Up, Dotz Nano’s sorbent supply contract with Soletair, and Euroclear’s portfolio through CUR8. ...
Captain's CDR Log #280: Why the same alkalinity removes different amounts of carbon in different seas
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. Why this matters now Ocean alkalinity enhancement (OAE) credits are sold by the tonne, but the removal behind each tonne is set by the water the alkalinity goes into. Last week, on 1 and 2 October, three open data deposits and one preprint landed that each treat location as the variable rather than the footnote: a global coastal efficiency study with its figure data and code on Zenodo, a lab dataset on how flow affects hydroxide dissolution, and a 20-day microcosm study from the upwelling system off northwest Spain. Read together, they say an OAE project’s address decides its carbon math. ...
CDR Daily Digest — 2026-10-06
Carbon removal is turning into infrastructure, and infrastructure needs three things a pilot plant does not: lenders, a workforce, and public consent. All three showed up in today’s stories, and the one place they do not yet line up is the ocean. That is the day’s pattern. The money is arriving through ordinary channels, debt rather than grants. The jobs are concentrating in the companies that build tools rather than the ones that remove tonnes. And a Nature Climate Change study says the public will only back any of it if the process looks fair and the institutions look trustworthy. So the constraint is shifting from “can this work” to “who pays, who builds, and who agrees.” ...
Take: Canada's New Nickel Mine Could Make Carbon Capture Obsolete
Take on a YouTube video from Musa Tule, originally posted 2026-10-05. Watch the source: https://www.youtube.com/watch?v=b34GVwxE66s TL;DR Explainer on Canada Nickel’s Crawford project near Timmins, Ontario: a 41-year, ~1.6 Mt-nickel mine whose ultramafic tailings can mineralize CO2. Mechanism covered accurately: serpentinized ore rich in brucite reacts with concentrated CO2 in-circuit, forming magnesium carbonate in hours. Useful for a lay audience. Title is wrong on its face — this is carbon capture and storage, just mineralized. Overstated. Economic framing is the real signal: carbonation as the business case that justifies a sulfide mine in an Indonesia-flooded market. Transcript cuts off before any tonnage or cost numbers for the carbonation itself. Treat the scale claim as unverified here. A general-interest Canadian channel (video here) walks through the Crawford nickel project and Canada Nickel Company’s plan to inject concentrated CO2 into tailings while they’re still moving through the processing circuit. The substantive argument is that a mine’s waste stream — millions of tonnes of already-crushed, already-reactive rock — is a cheaper mineralization reactor than anything purpose-built. ...
Enabling Tech leads CDR workforce with 7707 employees across 969 companies
This chart is a stacked horizontal bar showing CDR-attributable headcount across pathways on the vertical axis, with each bar segmented by business focus: pure-play companies whose entire reason for existing is CDR, divisions inside larger firms where CDR is one line of business, and “ecosystem” firms, the directory’s label for companies that sell tools, verification, brokerage, or software to those operators. Bar length is total attributed workers; the color split is where those workers actually sit. ...
Public CDR support hinges on trust and fairness, Nature Climate Change study finds
Carbon Herald just published New Study Examines What Matters Most For Public CDR Support. Carbon Herald reports on a study published in Nature Climate Change that examines the drivers of public support for carbon dioxide removal. According to the outlet, the researchers set out to assess which factors matter most when people form views on CDR, a question that has grown more pressing as governments and companies scale up removal targets. The article frames the work as a contribution to understanding how social acceptance might shape deployment of removal approaches alongside emissions cuts. The piece points readers to the underlying study for the detailed findings, which the summary available to us does not spell out, including the specific factors identified or the populations surveyed. ...
