Anthropic has joined Frontier, the carbon removal collective founded by Stripe, Google, and Shopify, becoming the first pure-play AI company to participate in the group. The move is part of a new $915 million funding tranche that nearly doubles Frontier’s total pledges to $1.8 billion.
The announcement marks Anthropic’s first climate-related commitment, arriving at a time when AI companies face growing scrutiny over energy-intensive data centre operations. Frontier has so far contracted nearly $700 million across more than 50 projects, removing 1.8 million tonnes of carbon to date.
Going forward, Frontier said it would concentrate funding on fewer, larger projects with the potential to remove at least one gigaton of CO2 annually, with new contracts running eight to ten years. The organisation also indicated that future recipients must demonstrate a pathway to government subsidy, signalling that private sector underwriting of carbon removal is not intended to be permanent.
