Carbon Removal Funding Boost Led by Stripe, Google and Salesforce Accelerates Gigaton-Scale Climate Technologies
A new $915 million funding round has been committed to accelerate the next phase of carbon removal development, marking one of the largest coordinated private-sector investments to date in engineered and nature-based carbon dioxide removal technologies.
The initiative, led by Frontier and supported by a coalition of major corporate buyers including Stripe, Google, Shopify, Salesforce, H&M Group and Anthropic, brings total commitments to $1.8 billion as the market for durable carbon removal continues to expand.
The funding reflects a shift in focus from early-stage experimentation to large-scale deployment, with buyers now concentrating capital on technologies considered most likely to reach gigaton-scale carbon removal potential. Frontier said the goal is to strengthen demand signals for companies capable of delivering long-term, measurable carbon dioxide removal at industrial scale.
Over the past four years, the carbon removal sector has expanded rapidly from a small group of startups to hundreds of companies working across more than 20 technological pathways. According to Frontier, tens of thousands of tonnes of carbon have now been delivered through verified projects, while early-stage infrastructure for measurement and verification has begun to mature across multiple methodologies.
The organisation said corporate purchasing has played a central role in this growth, with more than 350 buyers across industries including aviation, retail, financial services and manufacturing collectively purchasing nearly four million tonnes of carbon removal to date. Alongside this, governments in jurisdictions including the European Union, United Kingdom, United States, Japan and Canada have begun introducing demand-side policies that could support longer-term market expansion.
The latest funding round will focus on a narrower set of high-conviction technologies deemed capable of scaling to gigaton-level carbon removal. These include approaches such as mineralisation, ocean alkalinity enhancement, biomass-based carbon storage, enhanced rock weathering and direct air capture, each with different cost structures, infrastructure requirements and scalability constraints.
Frontier noted that while some pathways, such as direct air capture, remain capital-intensive and dependent on low-carbon energy availability, others such as enhanced rock weathering and biomass-based approaches may scale more quickly but face limitations in feedstock or land use. The organisation said a diversified portfolio of solutions is therefore likely to be required to meet global climate goals.
The funding model continues to operate as an advance market commitment, a mechanism designed to guarantee future demand and reduce investment risk for emerging technologies. By securing long-term offtake agreements, buyers aim to provide the revenue certainty needed for companies to build large-scale facilities and reach final investment decisions.
Frontier said the next phase of its strategy will prioritise projects that demonstrate clear pathways to sustained demand, whether through compliance markets, industrial regulation or direct government procurement. It also emphasised the importance of aligning private investment with public policy to accelerate deployment at scale.
As the sector moves towards industrialisation, Frontier highlighted that global carbon removal requirements could eventually require hundreds of billions of dollars in annual procurement. It compared this scale to existing global spending on waste management and agricultural subsidies, arguing that similar levels of financial commitment will be necessary to support long-term climate objectives.
The organisation said the latest investment round is intended to help bridge the gap between early innovation and full commercial deployment, ensuring that the most promising carbon removal technologies can scale responsibly while building the foundation for a much larger future market.
