OneStopESG just published Boeing Buys 20,000 Tonne Biochar and Enhanced Rock Weathering Carbon Removal Portfolio Through Supercritical. OneStopESG reports that Boeing signed a 20,000 tonne durable carbon dioxide removal portfolio through marketplace Supercritical, announced on 1 May 2026. The credits come from six suppliers - Exomad Green, Ground Up, InPlanet, NetZero, Varaha and PlanBoo - operating biochar and enhanced rock weathering projects in Brazil, Bolivia, Namibia and India. Supercritical screened over 200 projects against a 118 point framework covering additionality, permanence, measurability and operational readiness. The piece frames the deal as a move away from single supplier contracts toward diversified, criteria led procurement, with Supercritical CEO Michelle You describing the shift as buyers trusting procurement partners to assemble portfolios meeting defined quality standards rather than picking individual developers. ...

Co-reactive, a German startup turning industrial mineral waste into building materials, has switched on its demonstration plant in Erkrath. The facility runs a continuous process that combines CO₂ with mineral by-products to make carbon-negative construction materials, marking the company’s jump from bench chemistry to operating hardware. Why this matters Concrete and cement account for roughly 8% of global CO₂ emissions, and almost every mineralization startup claims it can fix part of that. Very few have moved past the lab. A working demo plant with a continuous process, not a batch reactor, is the step where most carbon mineralization companies stall. It is the difference between a chemistry result and a product you can sell. Mineralization also has a structural advantage over many other CDR pathways: the CO₂ is locked into a stable carbonate inside a material people already buy in enormous volumes. Verification is comparatively straightforward, and the product replaces a high-emission incumbent rather than requiring a new market. ...

Stockholm Exergi just hoisted a pipe bridge the length of an American football field into place, connecting Stockholm’s largest combined heat and power plant to a new BECCS (bioenergy with carbon capture and storage) facility next to the harbor. When operational, the retrofit will pull 720,000 tons of biogenic CO₂ out of flue gas each year, making it one of the largest engineered carbon removal projects under construction anywhere. Why this matters Most CDR headlines are about contracts, offtake deals, or modeling studies. This one is about steel in the air. Stockholm Exergi reached final investment decision just over a year ago, and they are already installing the backbone piping that will move flue gas from combustion to capture. That pace, from FID to major structural installation in roughly twelve months, is a useful data point for anyone tracking whether large-scale CDR can actually get built on timelines that matter. BECCS also sits in a strange spot in the CDR conversation. It is high on the technology readiness ladder compared to direct air capture, because every component (biomass combustion, amine-based capture, CO₂ compression, transport) has industrial precedent. But it depends entirely on two things being true: the biomass has to be genuinely sustainable, and the CO₂ has to be durably stored. The engineering is the easy part. Stockholm Exergi is now showing us what the easy part actually looks like. ...

A new Nature Sustainability paper just delivered a hard verdict on one of the most politically popular forms of carbon removal in Europe: burning trees to make electricity, then capturing the CO2. The answer, from Timothy Searchinger and colleagues at Princeton and the World Resources Institute, is that forest-fuelled BECCS (bioenergy with carbon capture and storage) will not produce net negative emissions for more than 150 years, emits more than unabated natural gas for decades, and roughly triples to quadruples the cost of electricity. ...

Swiss agricultural carbon company Cotierra has delivered its first 1,200 tCO₂e of soil carbon removal credits to myclimate, the Zurich-based climate project foundation, and extended the offtake partnership into 2027. The delivery, drawn from Cotierra’s 2025 production year, is one of the first sizeable tranches of agricultural soil carbon removals to actually land in a buyer’s account rather than sit as a forward contract. Why it matters Agricultural soil carbon has a credibility problem. The category has been dogged by questions about permanence, measurement accuracy, and whether claimed removals are additional to what farmers would have done anyway. Actual verified delivery, not promises, is what the segment needs to rebuild trust with corporate buyers. A 1,200-tonne delivery is modest next to what engineered removal players ship, but in soil carbon it counts as a real-world receipt. The 2027 extension signals myclimate is willing to commit to a multi-year pipeline from this supplier rather than treating it as a one-off pilot. ...

Cella has signed a research and technology collaboration with TotalEnergies to test its in situ mineralization platform for evaluating CO2 storage potential at industrial sites. The partnership covers the full workflow: site screening, injection design, and monitoring. It’s a notable signal that mineralization-based storage is getting serious attention from one of the world’s largest energy companies. Why it matters Most carbon storage conversations focus on injecting CO2 into deep saline aquifers or depleted oil and gas reservoirs, where the gas stays trapped but remains as CO2 for long periods. In situ mineralization takes a different approach. It aims to convert injected CO2 into solid carbonate minerals within the rock itself, locking the carbon away permanently. If Cella’s platform can reliably screen industrial sites for this kind of storage and then guide injection and monitoring, it could open up storage options that don’t depend on traditional geological traps. The fact that TotalEnergies, through its Carbon to Value (C2V) Initiative, is investing research effort here suggests the major energy players see mineralization as more than a lab curiosity. They want to know if it works at real industrial facilities. ...

Triodos Investment Management and Fondaction Asset Management have launched Value Nature Fund I, a €300 million closed-end fund that aims to convert farmland and forests to regenerative practices across Europe, Canada, and the United States. What makes this fund unusual: part of the manager’s performance-based pay will be tied directly to hitting biodiversity and climate impact targets, not just financial returns. Why it matters Natural capital investing has long been treated as a niche corner of sustainable finance, often associated with small pilot projects or grant-funded conservation. A €300 million target with institutional structure, a dual-continent strategy, and an intended Article 9 classification under the EU’s Sustainable Finance Disclosure Regulation (the highest sustainability category for investment products) signals something different. This fund is being packaged as a real-assets vehicle meant to attract larger pools of capital into land-use transition. For CDR, the relevance is clear. Regenerative agriculture and closer-to-nature forestry are among the primary land-based pathways for removing and storing carbon. Scaling these practices requires exactly the kind of institutional capital this fund is designed to mobilize. But the usual caveat applies: land-based carbon removal addresses residual emissions that can’t be eliminated through decarbonization. It is not a substitute for cutting fossil fuel use. ...

A new study from the Potsdam Institute for Climate Impact Research (PIK) finds that folding CDR into the EU Emissions Trading System could deliver roughly 60 million tonnes of CO₂ removals per year by 2050. The researchers propose a phased approach, with full integration of removal credits and residual emissions under a single carbon price arriving around 2040. If the design holds, Europe’s carbon market would shift from merely capping pollution to actively pulling carbon out of the atmosphere. ...

CDR trader Altitude is ramping up its purchases of biochar carbon credits, positioning itself to tackle what it sees as a fundamental mismatch between supply and demand in the carbon dioxide removal market. The firm, led by chief investment officer Benjamin Schulz, was built specifically to address structural bottlenecks in the CDR pipeline, and biochar is becoming a bigger part of that strategy. Why it matters The CDR market has a well-known problem: buyers want credits, but the supply of verified, high-quality removal tons is thin and lumpy. Projects take years to develop, financing is hard to secure, and the credits that do exist often get locked up in long-term offtake agreements with a handful of large corporate buyers. Traders like Altitude sit in the middle, trying to smooth out that friction by buying credits and making them available to a broader set of purchasers. The fact that Altitude is leaning harder into biochar tells us something about where the near-term supply is actually materializing. ...

Germany will need to remove 39 to 51 million tonnes of CO₂ per year by 2045 to hit its climate-neutrality target, according to a new study from Fraunhofer ISE, one of Europe’s leading energy research institutes. And the study delivers a blunt warning: delays in building out CO₂ transport and storage infrastructure significantly raise the risk of missing those targets entirely. Why it matters This is one of the first major studies to model CDR ramp-up within the full context of Germany’s energy system, rather than treating carbon removal as a standalone exercise. That distinction is important. CDR technologies need biomass, renewable electricity, and pipelines to move captured CO₂. Modeling them in isolation misses the bottlenecks. Fraunhofer ISE’s work makes those dependencies explicit, and the numbers are large enough to demand serious infrastructure planning starting now. ...
