CURA Lands $10M to Scale Low-Carbon Cement Tech
Carbon Herald just published CURA Raises $10M To Scale Cement Decarbonization Tech. Carbon Herald reports that CURA Climate Inc., a Canadian cleantech startup, has secured $10 million in financing aimed at accelerating the commercialization of its cement decarbonization technology. The funding is intended to help the company move from development toward broader deployment in an industrial sector responsible for roughly 7-8% of global CO2 emissions. Cement decarbonization has drawn growing investor interest as producers face pressure from climate policy and corporate procurement standards. The article positions CURA among a wave of startups targeting emissions from clinker production and process chemistry, though specific technology details and investor names are covered in the full piece. ...
Captain's CDR Log #261: PyroCCS and BIG both raised seed money for biochar, but they are not the same company
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. What does “biochar carbon removal” actually mean in 2026? Two seed rounds closed this week under the same pathway label. PyroCCS in Germany raised from Lotus One and Counteract. Biochar Industrial Group raised $1.5M pre-seed for pan-African expansion. Both are called biochar. Reading the two announcements back to back, they describe different businesses. ...
CDR Daily Digest — 2026-09-17
The infrastructure question is louder than the technology question Today’s stories keep circling the same point from different angles: CDR’s bottleneck in late 2026 is not whether the technologies work. It is whether the surrounding system - policy definitions, workforce, verification bundles, feedstock logistics - can carry the weight we keep piling on top. Rudy Krehbiel of EcoEngineers framed it directly: the question is which story carbon dioxide removal is actually in. Is it a climate story, an industrial policy story, a compliance story, or a commodity story? The answer changes who buys, who builds, and who writes the rules. Right now it is being told as all four at once, and that ambiguity is starting to show up as friction in specific deals. ...
Enabling tech dwarfs CDR with 7,700 workers versus 13,571 pure-play producers
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. ...
Captain's CDR Log #260: Why bundling methane avoidance with ERW removals is drawing scrutiny
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The largest enhanced rock weathering deal ever signed also quietly redefines what a “carbon removal” contract is. This week Google agreed to buy 1 million tonnes of methane elimination by 2030 and 1 million tonnes of ERW (enhanced rock weathering, spreading crushed basalt to draw down CO2) removals by 2040 from Terradot, and marketed the two together as one climate product. The bundling is the story. If this template sticks, every pure-removal seller will have to explain why their tonne is not swappable with a blended one. ...
CDR Industry Update - September 2026
CDR Industry Update - September 2026 A quiet month on the headcount, a busy one under the hood: 114 existing companies edited, zero net additions or removals. The directory held flat at 1,470 active companies this month, the first time in over a year we’ve seen a true zero on both the add and remove columns. That is worth pausing on. Through 2024 and most of 2025 we tracked steady monthly churn in the 15-40 range on each side, with the net often positive by single digits. September broke that rhythm entirely. ...
Captain's CDR Log #259: One sub-$100 biochar CORC print sits under a $150 durable-removal benchmark
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. A biochar CORC transaction reportedly cleared at under $100 per tonne of CO2 this week. The print came from Carba, sold to U.S. Bank, and was flagged by Kevin Lee Caster (@kevinleecaster.bsky.social on Bluesky): “As I understand it, Carba sold the biochar based CORCs to U.S. Bank for less than $100/tonne of CO2. I’m disappointed that the biochar will not be used as a soil amendment as that can help increase s[oil].” ...
569 pure-play CDR companies and most red dots are tiny
This violin plot sorts every pure-play CDR company in the Directory by its pathway (columns) and its headcount (vertical axis, log scale from 1 to 100+). Each dot is one company, coloured by its current liveliness tier — Active, Moderate, Suspect, or Likely Dead. The grey shape behind each column is the size distribution: where it bulges, that’s where most companies in that pathway sit. The value here is comparative. A raw company list tells you who exists; this view tells you where the weight sits. Pathways with most dots stacked at the bottom are dominated by sub-10-employee firms — many small entrants, few that have grown. Pathways with dots reaching up the column have produced operators that scaled past the founder-and-a-few-engineers phase. Colour (not vertical position) is what tells you the health story: red dots high up the column mean a sizeable operator went quiet; red dots on the floor are the long tail churning as it always has. ...
Carbon Unbound Merges Coastal Summits Into One North American Flagship
Carbon Herald just published Carbon Unbound Merges Its West Coast & East Coast Events Into One Flagship North American Summit. Carbon Herald reports that Carbon Unbound has announced a consolidation of its two regional summits into one unified North American gathering. The organization previously ran separate East Coast and West Coast events aimed at the carbon dioxide removal industry, bringing together CDR developers, buyers, investors, and policy figures. The merged format is positioned as a larger flagship convening for the sector across the continent. Additional details on venue, dates, and programming are covered in the full article on Carbon Herald. ...
Captain's CDR Log #257: Two overlapping EU ETS position papers show removal advocates preparing for the pre-2026 review fight
Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The policy at one glance Two industry position papers dropped inside a few weeks of each other, both aimed at the same target: getting permanent carbon dioxide removal (CDR) written into the EU Emissions Trading System (ETS) before the Directive’s next review closes. The Negative Emissions Platform’s paper on integrating permanent carbon removals into the EU ETS is the supplier-side opening bid. The DVNE Policy Brief on Carbon Removal in the EU ETS is the national-level echo. Together they bind on nobody. But they tell the European Commission which arguments the industry will run through MEPs and DG CLIMA between now and the review. ...
