Boeing has signed a multi-year carbon dioxide removal purchase agreement with Grassroots Carbon, a Texas-based company that quantifies soil carbon gains from improved grazing practices on working rangelands. The deal was reported by Carbon Herald on April 1, 2026. Financial terms were not disclosed. Why This Deal Is Noteworthy#Aviation is one of the hardest industries to decarbonize. Airlines and aerospace manufacturers face significant emissions from kerosene combustion at altitude — where the warming effects of contrails and NOx emissions compound the CO₂ impact. Direct electrification of long-haul aviation is not commercially viable in the near term. Sustainable aviation fuels are advancing but remain expensive and constrained by feedstock supply. ...

A busy Tuesday in CDR, with policy, funding, and geography all in motion at once. What We Covered Today#The EU Carbon Market Could Scale CDR to 60 Million Tonnes by 2050 The headline number from a new Joule paper by researchers at the Potsdam Institute: integrating carbon dioxide removals into the EU ETS could deliver around 60 million tonnes per year by 2050, primarily through DAC and BECCS. The mechanism is clean — a carbon price built into ETS provides the long-run certainty that grant-by-grant funding cannot. The authors lay out a three-phase integration roadmap, with the first phase focused on getting MRV and sustainability standards right before credits enter the market. The EU has committed to decide on ETS inclusion of removals by 2026. The timeline is real. ...

Gigablue announced the first close of its Series A at $20 million back in January — revealed at Davos, which tells you something about where the company is positioning itself. The round was led by Planet Ocean Capital, an ocean-climate-technology venture fund, with participation from additional VCs. The New Zealand mCDR trial we covered earlier today is the same Gigablue. The $20M is funding both that research and a broader scaling push. ...

A startup called Gigablue chartered a boat from Port Chalmers in Dunedin and headed out to the Bounty Trough, a stretch of deep ocean off New Zealand’s Otago coast. The plan: lower containment pens into the water, deploy 55kg of cellulose particles embedded with iron and manganese, and take water samples for three weeks. Radio New Zealand noticed. The resulting explainer they published is one of the better public accounts of what marine CDR actually is — and why a healthy dose of skepticism is the correct response. ...

remove, the European CDR accelerator, is expanding to Latin America. This is genuinely good news — and it’s been a while coming. The Program#The LatAm Accelerator will run on the same two-stage model that’s worked in Europe and North America: Foundations stage: An intensive deep-dive into the CDR ecosystem — LatAm-specific carbon markets, CDR policy, the buyer’s perspective, and MRV (monitoring, reporting, and verification) challenges. Startups refine their value proposition, then pitch on a Pitch Day that doubles as the selection gate for stage two. ...

RepAir Carbon just opened a European headquarters in Luxembourg, and the timing is deliberate. The Israeli direct air capture startup is expanding into Europe at exactly the moment EU carbon policy is accelerating: the Carbon Removal Certification Framework (CRCF) is taking shape, the ReFuelEU Aviation mandate is creating demand for sustainable aviation fuel, and Luxembourg itself has just launched a national CCUS & CDR Taskforce. What RepAir Actually Does#RepAir’s technology is electrochemical — specifically, a battery-inspired electrochemical cell where electrodes separated by a membrane react with CO₂ in incoming air or flue gas, capturing and concentrating it in a single step. ...

While Washington is busy dismantling climate policy, Brussels is quietly building the market architecture that could make carbon dioxide removal a viable industry. A new paper published in the journal Joule on March 31st makes the case — with numbers. The Study#Led by Darius Sultani and Michael Pahle at the Potsdam Institute for Climate Impact Research (PIK), the paper — How the EU can utilize its carbon market to scale up Carbon Dioxide Removal — models what happens when CDR technologies are integrated into the EU Emissions Trading System. ...

A milestone day for carbon markets: one buyer crossed 1 million tonnes financed, new research turned industrial waste into a CO₂ sink, and Europe’s financial sector quietly showed up for certified removal. What We Covered Today#Altitude Carbon Reaches 1 Million Tonnes Financed — With Bolivia This is the number the CDR market has been building toward. Altitude Carbon, a CDI portfolio company, became the world’s first commercial CDR buyer to cross 1 million tonnes financed — pushed over the line by a 305,000-tonne biochar deal with Empacar S.A. in Bolivia. What makes this notable isn’t just the size: it’s that Altitude is operating as a market-maker at scale, financing CDR across Southeast Asia, Bolivia, and beyond. The 1 million tonne mark is a proof point that commercial demand for durable carbon removal can actually accumulate. ...

There’s a number the CDR market has been building toward for years. This week, it arrived. Altitude Carbon has become the world’s first commercial CDR buyer to cross 1 million tonnes of carbon dioxide removal financed. The deal that pushed them over the line: a partnership with Empacar S.A. of Bolivia for over 305,000 tonnes of biochar carbon removal credits (CORCs) — on top of the 360,000+ tonnes Altitude had already financed in Southeast Asia and elsewhere. ...

CDR literacy has an English problem. Most of the best writing about carbon removal — the nuanced stuff that goes beyond “trees good, factories bad” — gets published in English, for English speakers. Meanwhile, millions of people in Italy, Germany, Brazil, Japan, and dozens of other countries are hearing about the climate emergency without the technical vocabulary to engage with what’s actually being done about it. That’s slowly changing. This week, The Good in Town, an Italian-language magazine focused on sustainability and society, published a clear-eyed explainer on biochar and why it matters for carbon removal: “Biochar: cos’è e perché è una soluzione per il carbon removal.” ...
