- Anthropic joined Frontier as the first pure AI company in the coalition, contributing to a new $915 million funding tranche that brings total pledges to $1.8 billion.
- Frontier has contracted nearly $700 million across more than 50 projects to remove 1.8 million tons of carbon since its 2022 launch, with backing spanning direct air capture, enhanced rock weathering, bio-oil, ocean antacids, and bioenergy with carbon capture and sequestration.
- Anthropic has yet to publish a sustainability report and has said it favors an "all of the above" approach to energy — language that typically translates into large purchases of polluting power.
- Frontier is shifting from many smaller bets to fewer, larger ones, with new contracts running 8–10 years and targeting projects capable of removing a gigaton (1 billion metric tons) of CO2 or more annually.
- Frontier now requires any new carbon removal partner to "show a path to government subsidy/support" before signing a contract, with deals planned as far out as 2040 in hopes governments will take the reins.
- Microsoft has been the largest buyer of carbon removal credits and is following the same shift toward fewer, larger deals, while Google is a founding member of Frontier alongside Stripe and Shopify.
Why it matters: Anthropic's first climate move arrives without a sustainability report, and the company has publicly signaled openness to polluting power — joining a removal coalition lets it keep emitting while paying to offset rather than cut. Frontier's new terms now require removal vendors to demonstrate a path to government funding, offloading the long-term bill for AI's emissions footprint from tech buyers to taxpayers.
