Frontier, the carbon removal purchasing coalition founded in 2022 with backing from technology firms such as Google and Stripe, said it will inject another $915 million into the carbon removal sector and added Anthropic as a new participant. The additional capital brings Frontier's committed funding to $1.8 billion.
Frontier's model is to commit to buying removal credits in advance - a structure intended to lower project financing risk and accelerate deployment. By offering pre-committed offtake demand, the coalition aims to help nascent removal technologies scale faster than they would in the absence of long-term purchase guarantees.
The new tranche of funding is earmarked for a set of specific removal approaches. Frontier said it will target ocean alkalinity enhancement, biomass-based removal, enhanced rock weathering, and direct air capture. The coalition stated that, collectively, these approaches have the potential to scale to gigaton levels of CO2 removed, though it also noted that each pathway carries its own cost profile and technology risks.
Operationally, Frontier plans to place approximately 10 to 15 focused bets. Those commitments will take the form of offtake contracts spanning eight to ten years, with some agreements extending as far out as 2040. The strategy prioritizes concentrated investment rounds rather than a broad, distributed set of small commitments.
The coalition did not provide a breakdown of how much each participating company contributed to the additional $915 million. Frontier emphasized the intentions behind the funding and the targeted technologies but did not disclose individual company-level financial allocations.
Frontier and participating companies framed carbon removal projects as an important tool for offsetting emissions that remain in sectors reliant on fossil fuels. Scientists cited by the coalition say that removal capacity will be necessary to address emissions from parts of the economy that continue to emit despite mitigation efforts.
This latest funding step signals continued private-sector engagement in the carbon removal market, with the coalition using pre-purchase contracts as its primary mechanism to reduce project risk and create predictable revenue streams for emerging technologies. At the same time, Frontier highlighted the technical and cost uncertainties that remain across the suite of targeted approaches.
Summary
- Frontier raised an additional $915 million for carbon removal, raising total pledges to $1.8 billion and adding Anthropic as a participant.
- Targeted technologies include ocean alkalinity enhancement, biomass-based removal, enhanced rock weathering, and direct air capture.
- Frontier plans roughly 10-15 focused offtake commitments over eight- to ten-year contracts, with some deals running to 2040.
Contextual note - Frontier says these approaches could scale to gigaton levels but each carries distinct cost and technology risks; the coalition did not reveal company-level contribution amounts.
