Carbon Herald just published Deep Sky Enters DAC-Focused Strategic Partnership With ENGIE. Carbon Herald reports that Canadian carbon removal developer Deep Sky has entered a strategic partnership with multinational energy company ENGIE, centered on direct air capture (DAC) projects. The collaboration brings together Deep Sky’s role as a project developer and aggregator of DAC technologies with ENGIE’s experience in large-scale energy infrastructure. The article frames the deal as part of Deep Sky’s broader push to scale carbon removal capacity and connect captured CO2 to permanent storage. Additional context in the piece points to related CO2 storage planning activity in England and South Wales tied to the partners’ broader ambitions. ...

Carbon Herald just published Iowa Landowners Protest Use Of Eminent Domain For Carbon Pipelines. Carbon Herald reports that landowners in Iowa gathered outside the State Capitol on Tuesday to protest the use of eminent domain for carbon dioxide pipeline projects. The demonstration reflects ongoing tension between pipeline developers seeking to route CO2 infrastructure through agricultural land and property owners who object to compulsory easements. Eminent domain has become a flashpoint in the Midwest as multiple CCS-linked pipeline proposals advance through state regulatory processes. Iowa has been a focal point because of its concentration of ethanol facilities, which are among the prospective CO2 sources feeding planned pipeline networks. The protest follows a series of hearings and legal challenges over whether private CO2 pipelines qualify for eminent domain authority under Iowa law. ...

This chart plots every pure-play CDR company in the Directory as a single dot. The horizontal axis is the company’s founding year (estimated from its primary domain registration), the vertical axis is its current headcount on a log scale, and the colour codes the company’s pathway. The shaded blue background traces overall company density — darker patches mark where the crowd of pure-plays sits. The value here is shape, not ranking. A bar chart would tell you how many companies exist in each pathway; this view tells you the entire industry’s growth contour at one glance — when did the wave of small startups hit, where are the rare big older operators, what cluster sits on the floor of “still under five people”. Outlier dots near the top of the chart are the names everyone already knows; the dense low band is where most of the industry actually lives. ...

Mining waste, market concentration, and the feedstock question Today’s stories cluster around one uncomfortable truth: the CDR market is still defined by who buys, not what works. Microsoft’s pause has revealed that a single buyer drove roughly 80% of durable demand. Meanwhile, the supply side keeps innovating on feedstocks and certification, building infrastructure for a market that does not yet have enough customers. This is the gap CDR has to close in 2026. Technology readiness is running ahead of demand depth. ...

Carbon Herald just published Verde And Isometric To Commercialize A New Category Of Carbon Credits. Carbon Herald reports that Verde Resources has signed a strategic partnership with Isometric to commercialize what the companies describe as a new category of carbon credits. Isometric operates as a carbon removal registry focused on scientific rigor in measurement and verification, while Verde Resources develops nature-based and engineered removal projects. The collaboration is positioned as a step toward expanding the menu of credit types available to corporate buyers, though the article frames the announcement around the partners’ intent to standardize methodology and issuance for the new category. Specific issuance volumes, pricing, and buyer commitments are not detailed in the recap. ...

Heatmap News just published Carbon Removal After Microsoft. Heatmap News reports that Microsoft, by far the largest buyer of carbon removal credits, has informed suppliers it is pausing new purchases. The company bought more than 70 million tons of CDR credits in recent years, including 45 million tons last year alone, dwarfing the next largest buyer Frontier at 1.8 million tons total since 2022. Microsoft says the pause is not permanent and that its 2030 carbon negative goal remains in place, framing the change as a pacing adjustment. Industry analysts quoted in the piece say many CDR startups built business models that effectively assumed Microsoft would be the backstop buyer, and a pullback removes roughly 80% of annual demand. ...

Carbon Herald just published NEP Taps DNV For CO2 Transport Certification. Carbon Herald reports that DNV has been selected as Independent Certifier for the Northern Endurance Partnership (NEP), the joint venture handling CO2 transport and storage for the East Coast Cluster in the UK. In this role, DNV will provide independent verification of the design, construction, and operational readiness of NEP’s CO2 transport infrastructure, which is intended to move captured emissions from industrial sites in Teesside and Humber to offshore storage in the North Sea. The certification work is positioned as a step toward delivering one of the UK’s first large-scale CCS networks under the government’s cluster sequencing program. ...

Each dot on this scatter is a single CDR pathway - direct air capture, enhanced rock weathering, biochar, ocean alkalinity, mineralization, and the rest. The horizontal axis counts how many companies are working that pathway; the vertical axis sums the employees across those companies. Linear scales on both, so distance on the page matches distance in the numbers. What this view reveals that a headcount table cannot is the shape of the industry. A pathway sitting high and to the right is crowded with firms and staffed deeply. One sitting high but to the left is a pathway dominated by a few large companies. Low and to the right means many small teams chasing the same idea. The spread between these corners is the story of where capital and talent have actually landed, versus where the field is still a cottage. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The rock-based carbon removal pathway has quietly stopped being a science project and started being a mining-industry pivot. Three announcements in three weeks, on three continents, all point to the same insight: tailings piles are the new feedstock asset class for durable CDR. Start with Quebec. The Quebec Surficial Mineralization Hub launched with Frontier backing, and the framing is what matters. Frontier called Quebec’s industrial legacy, meaning its mining tailings, “one of the world’s biggest carbon removal opportunities.” Liability becomes feedstock. The throughput numbers are not small either. “Not spreading, either aerating large piles or using reactors. You do end up getting more mass at the end than you dig up due to carbonation, but we still expect on the order of >30k tons CO2 stored per acre.” - Zeke Hausfather (@hausfath.bsky.social on Bluesky). Per-acre density at that level is what separates a serious feedstock thesis from a boutique demo. ...

The UK is trying to corner CDR finance. The plants are showing up to match. Today’s stories line up around one country. The UK posted a $1.6 billion voluntary carbon market, the City of London made the case for scaling it further, and Wiltshire became home to what will be the country’s largest biochar carbon-removal facility. Meanwhile in Germany, a CO2-to-concrete demo went live, and a separate piece argued that buyers can no longer treat offtake diligence as a one-and-done check. The pattern: CDR is moving from pilot announcements to operating plants, and the financial plumbing around them is getting more demanding. ...
