Anthropic, the artificial intelligence company behind the Claude chatbot, has become the first pure AI startup to join Frontier, a carbon removal collective founded by major tech companies. The company is contributing to a new $915 million tranche of funding, bringing Frontier's total pledges to $1.8 billion. This marks Anthropic's first climate-related deal, even as the company has yet to publish a sustainability report and has previously favored an "all of the above" energy strategy.
Frontier was launched in 2022 by Stripe, Google, and Shopify to help tech companies fulfill their climate pledges. The collective vets carbon removal projects and signs contracts with developers it believes can scale. So far, Frontier has contracted nearly $700 million across more than 50 projects, removing 1.8 million tons of carbon dioxide. The new funding nearly doubles the collective's pledges and will help bolster its position in the nascent carbon removal industry.
Anthropic's climate pivot
Anthropic's membership comes at a time when AI companies have been on an energy buying spree, not all of which has been clean. The company has yet to produce a sustainability report, and it has said it favors an "all of the above" approach to energy, a statement that typically translates into large purchases of polluting power. However, joining Frontier may signal changing attitudes within the company toward climate responsibility.
The carbon removal credits supported by Frontier allow companies to continue emitting some pollution while offsetting it through verified removal projects. The credits can be subtracted from a company's carbon footprint, similar to how profits might counter debts on a balance sheet. Frontier vets projects, serving as a shared resource for companies interested in carbon removal.
Frontier's evolving strategy
In the announcement of the new pledges, Frontier said that funding for future projects will come with a higher level of scrutiny. The organization will fund fewer projects, focusing on those that it thinks have the best chance at removing a gigaton—1 billion metric tons—of CO2 or more annually. New contracts will run around eight to 10 years, Frontier said.
Since its launch, Frontier has backed a range of carbon removal technologies, including direct air capture, enhanced rock weathering, bio-oil, ocean antacids, and bioenergy with carbon removal and sequestration. The shift from lots of smaller bets to fewer larger ones mimics what appears to be happening at Microsoft, which has been the largest buyer of carbon removal credits.
The challenge of scaling carbon removal
Though companies want the carbon removal market to grow and mature, they are making it clear that they don't want to underwrite it in perpetuity. For any new contract it signs, the carbon removal company must "show a path to government subsidy/support," a Frontier spokesperson told TechCrunch. The UN Intergovernmental Panel on Climate Change has said that carbon dioxide removal technology will be necessary if the world is to reach net zero emissions, though few companies or consumers are interested in footing the bill. Like clean water, the problem is almost certain to fall on governments eventually.
Frontier said it will contract as far out as 2040. It didn't say what will happen after that, but it's pretty clear they hope governments will have started to take the reins by then. If they don't? At the rate the climate is warming, we'll have bigger problems on our hands.
The carbon removal industry is still in its early stages, with many technologies unproven at scale. Direct air capture, for example, currently removes only a few thousand tons of CO2 per year globally, far from the billions needed. Enhanced rock weathering spreads crushed silicate rocks on farmland to absorb CO2, but its long-term effectiveness is uncertain. Bio-oil involves injecting waste biomass deep underground, where it can be stored indefinitely. Ocean antacids aim to reduce ocean acidification while absorbing CO2, but ecological impacts are still being studied.
Anthropic's involvement brings significant attention to the carbon removal space. The AI industry's enormous energy consumption has been under scrutiny, with data centers expected to consume up to 7% of global electricity by 2030. By joining Frontier, Anthropic can claim to be addressing its carbon footprint, though critics may note that carbon removal credits are not a substitute for direct emissions reductions.
The $915 million new tranche includes contributions from other new members, though Anthropic is the only AI startup. Google remains a founding member, and other tech companies like Stripe and Shopify continue to pledge. The collective's shift to larger, longer-term contracts reflects a maturing market that demands proven scalability.
As of 2026, the world is still far from the carbon removal capacity needed to meet Paris Agreement goals. The gigaton scale that Frontier targets is ambitious: total global carbon removal today is less than 0.01% of that. To achieve that scale, governments will need to step in with subsidies, tax credits, and regulatory frameworks. Without such support, even the most promising technologies may fail to attract private investment.
Anthropic's entry into this ecosystem could encourage other AI companies to follow suit. With AI's skyrocketing energy demands, tech companies face growing pressure to demonstrate environmental responsibility. Carbon removal offers a way to offset unavoidable emissions, but only if the market can scale sustainably.
In summary, the partnership between Anthropic and Frontier represents a significant milestone for both the AI and carbon removal industries. It underscores the urgency of addressing climate change while acknowledging the practical challenges of decarbonizing rapidly growing sectors. The next few years will be critical as Frontier and its members work toward a gigaton-scale future.
