First Buyers' Intelligence Report Maps How CDR Procurement Has Evolved from 2024 to 2026
Built from three years of proprietary buyer intake data across 74 organisations, the report documents how CDR procurement behaviours have changed and the current challenges facing corporate buyers and procurement teams.
Google makes its largest-ever carbon removal purchase through Terradot
Google has signed a megaton-scale agreement with enhanced rock weathering company Terradot, purchasing 1 million tonnes of near-term methane impact by 2030 and 1 million tonnes of durable CDR by 2040. The project deploys Alternate Wetting and Drying across 200,000 hectares of rice farmland in Rio Grande do Sul, Brazil — cutting methane emissions immediately — while spreading crushed volcanic rock to deliver permanent removal as the methane impact expires. It is the largest ERW project ever undertaken and the first of any kind to combine superpollutant elimination with durable carbon removal at this scale.
Isometric raises its Series A to $50 million with strategic investment from Intercontinental Exchange as carbon credit certification scales beyond removal
London-based carbon certification company Isometric has secured backing from ICE, operator of the world's largest environmental markets, bringing total Series A funding to $50 million and combined seed and Series A funding to $75 million. ICE joins existing backers AVP, Lowercarbon Capital, Plural, and John Doerr. The investment will combine Isometric's AI-powered certification platform — which has been contracted to certify over 16 million tonnes — with ICE's market infrastructure, signalling a major step toward institutional-grade carbon credit verification infrastructure.
Japan Airlines and Climeworks Solutions announce world's first CORSIA-compliant carbon removal agreement
The landmark pilot agreement positions JAL to lead the industry in securing CORSIA-compliant carbon removals, while actively supporting the development of permanent Direct Air Capture (DAC) technology.
Carbfix achieves 99.6% CO2 capture efficiency in landmark carbon mineralisation milestone
Carbfix has confirmed that its Project Silverstone deployment at ON Power's Hellisheiði power plant captured 99.6% of CO2 and 100% of hydrogen sulfide between July 2025 and June 2026 — permanently mineralising more than 120,000 tonnes of CO2 and 50,000 tonnes of H2S in basalt rock formations since operations began. The project, backed by €3.87 million from the EU Innovation Fund, demonstrates that geothermal carbon capture with sub-surface mineralisation can operate at near-perfect efficiency at commercial scale.
Exomad Green and Carbonfuture Expand Long-Term Supply
The agreement secures more than 1,100,000 tonnes of biochar carbon removal supply, including a pre-existing allocation for 2026, to be made available to corporate buyers via Carbonfuture through 2035, and reaffirms the more than 1,200,000 tonnes already contracted for delivery under existing multi-year agreements.
ExxonMobil secures Texas Class VI permits for 53 million tonnes carbon storage site
The Railroad Commission of Texas has approved Class VI injection well permits for ExxonMobil's Rose carbon capture and storage facility, clearing a critical regulatory hurdle for one of the largest CCS projects in the US and strengthening the company's position as the dominant CCUS infrastructure operator in the Gulf Coast region.

National Academies of Sciences publishes major 2026 update on marine CDR
A new report from the National Academies, the most comprehensive independent assessment of ocean-based carbon dioxide removal published to date, finds that marine CDR has advanced substantially through growing research activity, private sector investment, and field testing, but that fundamental questions about scalability, permanence, ecological effects, and measurement remain unanswered. New modules cover ocean alkalinity enhancement and updated governance frameworks.
Biochar Industrial Group raises $1.5 million pre-seed to scale carbon removal across Sub-Saharan Africa
Nigerian climate technology company Biochar Industrial Group has closed a pre-seed round led by BREEGA with support from The Catalyst Fund and the Mulago Foundation, to expand its model of converting agricultural waste at food-processing factories into biochar carbon removal credits. The company targets the intersection of industrial waste management, soil health, and durable CDR in African food and agriculture supply chains.
PyroCCS secures funding from Lotus One Investment, Counteract and private investors to build an integrated biochar and carbon removal supply chain
PyroCCS has closed a funding round to scale its multi-product biochar revenue model covering biochar, renewable energy, and carbon removal credits, which the company argues unlocks project financing that single-revenue CDR models cannot access. The raise follows a carbon removal credit purchase agreement with Tencent through the CarbonX 2.0 initiative.
90% of voluntary carbon credit buyers report commercial gains from purchases as carbon markets shift from compliance cost to strategic investment
A new market survey finds that nine in ten companies purchasing carbon credits now report measurable commercial benefits — including supply chain resilience, stakeholder credibility, and employee engagement — signalling a structural shift in how corporate buyers frame voluntary carbon market participation.
Avnos launches its first factory-built direct air capture product line
Avnos has unveiled a standardised, factory-manufactured version of its hybrid direct air capture technology, designed to reduce installation time and cost at infrastructure scale. The HDAC™ Module is the company's first off-the-shelf product line, enabling faster deployment across multiple sites without bespoke engineering for each location, a significant step toward industrialising DAC at the project scale needed to meet corporate and sovereign CDR demand.
Ineos opens the first full-scale CO₂ storage site in the EU
Greensand expects to store up to 400,000 tonnes of CO₂ annually in this first commercial phase, scaling toward an expected 4-8 million tonnes annually at full capacity.
CURA raises $10M USD to decarbonize cement production
The latest financing was led by Zacua Ventures, with participation from Sandpiper Ventures, Vantage Futures, Amplify Capital, UCeed, and Mount Rundle Club. This financing will help them build a 100-tonne-per-year pilot in Alberta, engineer their first 30,000-tonne-per-year commercial demonstration plant, and grow the team.
