Hey, I’m CaptainDrawdown

This chart is a stacked bar count of every company in the CDR Directory, grouped along the x-axis by removal pathway (direct air capture, enhanced weathering, biochar, ocean alkalinity, and so on), with each bar segmented by business focus: pure-play producers, brokers and marketplaces, and firms where CDR is a side business bolted onto a different core model. The total height tells you which pathways are crowded with company formation. The segment mix tells you something a raw count hides: whether a pathway’s apparent size is built on operators actually delivering tonnes, on intermediaries reselling them, or on incumbents whose CDR line is a minor adjunct. Two pathways with identical totals can have very different underlying economies once you see the split. ...

Carbon Herald just published Mantel And Wood Partner To Scale High-Temperature Carbon Capture. Carbon Herald reports that carbon capture developer Mantel has entered into a memorandum of understanding with engineering services firm Wood to accelerate the rollout of high-temperature carbon capture technology. The partnership pairs Mantel’s molten salt-based capture approach, which targets industrial heat applications, with Wood’s engineering and project delivery capabilities. The collaboration is positioned as a step toward commercial-scale deployment across hard-to-abate sectors. Specific project sites, capture volumes, and timelines were not detailed in the announcement covered by the outlet. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. The critique “One mature tree takes up ~25 kg of CO₂/year, so 100 million trees will take up 2.5 MtCO₂. That’s a time machine that takes us back ~33 minutes in a year. Nature will not save us from fossil fuel CO₂.” That is David Ho (@davidho.bsky.social), and it is the cleanest attack on nature-based removal in circulation right now. ...

Carbon Herald just published China’s Tencent And CATL Join New Carbon Credit Coalition With 10M-Ton Target. Carbon Herald reports that Chinese tech and battery giants Tencent and CATL have joined a newly formed carbon credit coalition based in Singapore. The group has set a target of 10 million tons of carbon credits, positioning itself as a notable buyer-side bloc in the voluntary carbon market. The involvement of two major Chinese corporates signals growing demand from Asia-Pacific firms for offset supply, and reflects an effort to coordinate purchasing through a single regional vehicle rather than fragmented bilateral deals. The outlet frames the move within broader trends of corporate climate commitments and shifting carbon market activity outside Europe and North America. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. This week in London, Jim Mann stood on the Carbon Removal Investment Summit stage and told a room of investors that enhanced rock weathering’s economics do not resolve on a spreadsheet. They resolve in a specific watershed, on a specific farm, with a specific basalt source feeding specific soil chemistry downstream. According to UNDO’s own recap of the panel, Mann’s argument was blunt: generic tonne accounting hides where ERW (enhanced rock weathering) actually works and where it does not. ...

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’s signal isn’t a single megadeal — it’s the slow consolidation of plumbing. Microsoft re-entered the buyer narrative just as Europe’s Buyers’ Club inched toward operational status and Singapore-plus-World-Bank stood up new Article 6 infrastructure. Meanwhile, a Nature paper put a serious crack in the integrity story underpinning US forest offsets, a reminder that the integrity layer is still load-bearing for everything being built on top. ...

Carbon Herald just published Italian University Launches Mobile Carbon Capture Pilot Facility. Carbon Herald reports that Politecnico di Milano, one of Italy’s leading technical universities, has opened a mobile pilot facility for carbon capture research based in Piacenza. The unit is designed to be transportable to different industrial sites, allowing researchers to test capture technologies under real operating conditions rather than only in a fixed lab setting. The project aims to support scaling pathways for capture systems across varied emission sources in Italian industry. Further technical specifications, partners, and funding details are covered in the full article. ...

Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all. What does a corporate CDR offtake actually look like in 2026? This week gave us two answers, signed within days of each other, and they are not the same answer. Microsoft locked in 650,000 tonnes of BECCS (bioenergy with carbon capture and storage) from Denmark’s BioCirc over seven years. Lufthansa signed a multi-year deal with aggregator Senken covering both engineered and nature-based removals. Same market on paper. Two completely different transactions underneath. ...

Carbon Herald just published AIRCO Opens Pennsylvania Manufacturing Hub For Modular Fuel Systems. Carbon Herald reports that industrial technology company AIRCO has launched a new manufacturing and integration hub in Pennsylvania. The site is intended to scale production of the company’s modular fuel systems, which combine captured CO2 and hydrogen inputs to produce synthetic fuels. The location is positioned to take advantage of regional industrial infrastructure and workforce, and the company frames the facility as a step toward commercial-scale deployment of its technology. Specific output figures, customer commitments, and timelines for first deliveries were noted as part of the company’s broader rollout plans. ...

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 In a single week, two major buyer coalitions launched on opposite ends of Eurasia, and they are not the same animal. Singapore’s ARC Coalition pools voluntary corporate money across Asia-Pacific for a mix of avoidance and removal credits. The EU’s CDR Buyers’ Club is being designed as a demand aggregator for durable removals tied to a forthcoming compliance regime. If you sell tons, the difference between these two clubs is the difference between two very different decades. ...
