Anthropic, the artificial intelligence company behind the Claude language model, has become the first AI startup to join Frontier, a collective of companies dedicated to advancing carbon dioxide removal technologies. The announcement, made on June 17, 2026, includes a new $915 million tranche of funding, nearly doubling Frontier's total pledges to $1.8 billion. So far, Frontier has contracted nearly $700 million across more than 50 projects to remove 1.8 million tons of carbon from the atmosphere.
Frontier was founded in 2022 by Stripe, Google, and Shopify, with the goal of helping tech companies fulfill their climate pledges by investing in nascent carbon removal technologies. The collective vets carbon removal companies and signs contracts for those it believes will be able to deliver at scale. Companies that pledge money to Frontier typically use the carbon removal credits to reduce their publicly listed carbon footprints, similar to how profits might offset debts on a balance sheet.
Anthropic's membership is notable because it is the first pure AI company to join the ranks. While Google is a founding member, Google is a diversified technology company with a long history of climate initiatives. In contrast, Anthropic is solely focused on AI research and development. Its involvement comes at a time when AI companies have been on an energy buying spree, not all of which has been squeaky clean. The energy demands of training and running large AI models have skyrocketed, leading to increased scrutiny of the environmental impact of the AI industry.
For Anthropic, joining Frontier represents its first climate-related deal. The company has yet to produce a sustainability report, and it has stated that it favors an "all of the above" approach to energy, a statement that typically translates into large purchases of polluting power. However, the move to join Frontier might signal changing attitudes within the company. By committing to carbon removal credits, Anthropic is acknowledging that it cannot eliminate all its emissions and is willing to invest in technologies to offset them.
The new funding will help bolster Frontier's position in the carbon removal industry, which is still in its infancy. Carbon removal technologies include direct air capture, enhanced rock weathering, bio-oil injection, ocean antacids, and bioenergy with carbon capture and sequestration. Each of these approaches has different levels of maturity, cost, and scalability. Frontier's role is to identify the most promising technologies and provide them with the funding needed to grow.
Frontier's founding companies, and others that have joined, face a dilemma. Many want to hit zero emissions in the next decade or two, but there are some emissions they cannot eliminate today, such as those from air travel or certain industrial processes. Carbon removal credits allow them to continue emitting some pollution while funding projects that remove an equivalent amount of CO2 from the atmosphere. However, the carbon removal market is still nascent, and there are few large-scale providers that can remove the amount of carbon companies need. Frontier aims to accelerate the development of these providers.
In the announcement of the new pledges, Frontier said that funding for future projects would come with a higher level of scrutiny. The organization indicated it will fund fewer projects, focusing on those that it believes have the best chance of removing a gigaton — 1 billion metric tons — of CO2 or more annually. New contracts will run around eight to 10 years, which is longer than typical corporate contracts and provides stability for carbon removal startups.
This 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. Microsoft has invested heavily in carbon removal and has set ambitious goals to become carbon negative by 2030. However, even Microsoft is moving toward larger, longer-term contracts with proven technologies rather than spreading its investments across many early-stage projects.
Though companies want the carbon removal market to grow and mature, they are making it clear that they do not want to underwrite it in perpetuity. For any new contract it signs, Frontier requires the carbon removal company to "show a path to government subsidy/support," a Frontier spokesperson told TechCrunch. This reflects the belief that carbon removal, like clean water or public health, is ultimately a public good that will require government funding to scale to the necessary levels.
The UN Intergovernmental Panel on Climate Change has stated that carbon dioxide removal technology will be necessary if the world is to reach net zero emissions by mid-century. However, few companies or consumers are interested in footing the bill for these expensive technologies. The cost of direct air capture, for example, can be hundreds of dollars per ton of CO2 removed, far higher than the cost of reducing emissions at the source. As a result, the burden is almost certain to fall on governments eventually. Frontier said it will contract as far out as 2040, indicating its expectation that governments will start taking the reins by then.
If governments do not step in, the implications are grim. At the rate the climate is warming, the world will face more severe heatwaves, droughts, floods, and other extreme weather events. The failure to scale carbon removal could mean that even with aggressive emissions reductions, the world will overshoot its climate targets, leading to irreversible damage to ecosystems and human societies. Anthropic's participation in Frontier is a small but significant step in the right direction, but much more needs to be done.
Anthropic's decision to join Frontier also reflects a broader trend among AI companies to address their carbon footprint. As AI becomes more pervasive, the energy consumption of data centers is increasing rapidly. Companies like OpenAI, Google DeepMind, and Microsoft are all exploring ways to reduce the energy use of their AI models, including more efficient hardware, software optimizations, and renewable energy procurement. However, these measures can only go so far, and carbon removal provides a way to compensate for residual emissions.
The carbon removal industry itself is evolving. Early investments by Frontier and other buyers have helped bring down the cost of some technologies. For example, direct air capture costs have fallen from over $1,000 per ton a decade ago to around $250-600 per ton today, and there is optimism that further scale could bring costs below $100 per ton. Enhanced rock weathering, which involves spreading crushed silicate rocks on farmland to accelerate natural weathering processes, is also gaining traction as a relatively low-cost option. However, each technology has its own environmental impacts and scalability challenges.
Frontier's new funding announcement comes at a time when climate tech investment is facing headwinds. After a boom in 2021-2022, investment in climate tech has slowed due to higher interest rates and a broader downturn in venture capital. However, corporate commitments to net zero remain strong, and carbon removal is seen as a necessity for companies that cannot fully decarbonize their operations. The involvement of a high-profile AI startup like Anthropic could help attract more mainstream attention to carbon removal and encourage other companies to join the effort.
Anthropic has not disclosed how much it is contributing to the new $915 million tranche, but its participation is symbolic of the growing awareness within the AI industry that energy consumption has environmental consequences. As AI models become more powerful and widely used, the industry will need to find ways to mitigate its impact. Carbon removal is one tool, but it is not a silver bullet. The most effective strategy remains reducing emissions at the source through energy efficiency, renewable energy, and smarter algorithms.
Frontier's new contracting strategy also reflects lessons learned from the early years of the carbon removal market. Some early projects failed to deliver, either because the technology did not work as expected or because the company went bankrupt. By focusing on fewer, larger, and longer-term contracts, Frontier hopes to increase the likelihood that carbon removal actually happens. The shift also puts pressure on carbon removal startups to demonstrate that they have a viable path to scale without relying solely on corporate buyers.
The carbon removal credits market is still relatively small, with total voluntary carbon market size estimated at around $2 billion in 2023, of which carbon removal credits accounted for a small fraction. Most credits are still from avoided emissions projects like rainforest protection, which do not actually remove CO2 from the atmosphere. Frontier's focus on removal credits is meant to build a market for high-quality, permanent removals that can complement emissions reductions.
In conclusion, Anthropic's entry into Frontier marks a milestone for the AI industry and for carbon removal. It demonstrates that even companies in energy-intensive sectors can take responsibility for their climate impact. The success of Frontier and similar initiatives will depend on continued corporate commitment, technological breakthroughs, and eventually government support. For now, the $1.8 billion in pledges provides a strong foundation, but the scale of the challenge is enormous. The world needs to remove billions of tons of CO2 annually by mid-century, and the current pace of investment is only a fraction of what is needed. Anthropic's participation is a hopeful sign, but it is just the beginning.
