A coalition of tech companies is committing an additional $915 million to carbon removal projects, supporting a sector that many climate experts view as essential for achieving long-term emissions targets.
The funding comes through an advance market commitment (AMC) initiative called Frontier, launched in 2022 by Stripe, Google and other tech firms. The new pledge nearly doubles Frontier’s previous commitment, bringing total purchasing commitments for carbon removal credits to approximately $1.8 billion. Anthropic has joined the coalition as a new participant.
Frontier uses a model designed to accelerate emerging carbon removal technologies by guaranteeing future purchases of carbon removal credits. These commitments provide developers with predictable demand, making it easier to attract financing and build commercial-scale operations.
Key Carbon Removal Technologies
Rather than spreading investments broadly across the sector, Frontier plans to concentrate this round of funding on a select group of technologies that it believes have the greatest potential to scale. The organization expects to make roughly 10 to 15 long-term purchasing commitments through offtake agreements that may extend as far as 2040.
Among the technologies receiving attention are direct air capture systems, enhanced rock weathering, ocean alkalinity enhancement and biomass-based carbon removal approaches.
Each technology addresses atmospheric carbon dioxide differently. Direct air capture uses industrial systems to remove carbon dioxide directly from ambient air. Enhanced rock weathering accelerates natural geochemical processes by distributing minerals like basalt across farmland, enabling carbon to be absorbed and stored over time. Ocean alkalinity enhancement increases the capacity of seawater to absorb carbon dioxide by introducing alkaline materials into marine environments.
Frontier is also focused on approaches that combine biological processes with carbon capture infrastructure. Biomass-based removal systems, including bioenergy production combined with carbon capture and storage, work to permanently sequester carbon while generating useful energy.
The coalition believes these technologies could eventually remove carbon dioxide at gigaton scale, though significant technical, economic and regulatory challenges remain.
The Frontier commitment demonstrates growing recognition that carbon removal will likely play a key role in climate strategies, particularly for industries where eliminating emissions remains difficult. Sectors like aviation, heavy manufacturing and certain industrial processes continue to rely on fossil fuels or emissions-intensive operations that cannot easily be replaced with current technologies.
The carbon removal market has expanded rapidly in recent years. Tech companies have become some of the sector’s most active buyers, using long-term purchase agreements to stimulate development of technologies that are still in early commercial stages.
Microsoft has emerged as the largest purchaser of engineered carbon removal credits, while Google and Frontier have also become significant market participants. Their involvement has helped create demand for projects that might otherwise struggle to secure financing.
Industry participants argue that advance purchase agreements can have an impact beyond direct funding. Companies developing carbon removal systems often need to demonstrate future revenue streams before securing private investment or government support. Long-term contracts from organizations such as Frontier can provide that validation.
Indeed, several carbon removal developers have reported that early purchasing commitments helped them move from demonstration projects to commercial deployment. In some cases, the contracts have also strengthened applications for public-sector funding and incentive programs.
