Frontier Carbon Removal Coalition Adds $915 Million and Welcomes Anthropic
Frontier, a carbon removal coalition backed by Google and Stripe, has increased its funding by $915 million, bringing its total financial commitment to $1.8 billion. According to Reuters, the group recently added AI firm Anthropic as a member to help accelerate the scaling of carbon removal startups through long-term purchase agreements.
Why is Big Tech using offtake contracts for carbon removal?
Frontier uses “offtake contracts” to reduce the financial risk for early-stage climate startups. These are 8-to-10-year agreements where the coalition commits to buying carbon removal credits before the technology is fully scaled. This provides startups with a guaranteed revenue stream, which makes it easier for them to secure traditional investment.
The coalition’s total funding grew from its 2022 launch to the current $1.8 billion mark. By promising to buy credits in advance, Frontier aims to lower the “green premium”—the higher cost of new, clean technologies compared to existing, polluting ones.
Which technologies are receiving this $1.8 billion investment?
The coalition targets four primary innovative methods that Reuters reports are currently facing technical and cost risks but possess high theoretical growth potential:

- Direct Air Capture (DAC): Using giant fans and chemical reactions to pull CO2 directly from the sky.
- Enhanced Rock Weathering: Spreading crushed silicate rocks on land to chemically bind CO2.
- Biomass-based Removal: Using organic materials to capture carbon, often storing it underground.
- Ocean Alkalinity Enhancement: Adding alkaline substances to seawater to increase the ocean’s capacity to absorb CO2.
How does Anthropic’s entry signal a trend in AI?
The addition of Anthropic, the creator of the Claude AI models, marks a trend where major AI labs are proactively managing their environmental footprints. Training large language models requires massive amounts of energy and water. By joining Frontier, AI companies are shifting from simple carbon offsets to permanent carbon removal.
This move places Anthropic alongside other tech giants in a race to ensure that the intelligence boom doesn’t come at the cost of climate goals. The focus is now on “high-durability” removal, meaning the carbon is stored for centuries rather than decades.
What are the risks of these long-term climate bets?
The $915 million increase in funding acknowledges that carbon removal is a high-risk venture. According to the Reuters report, many of these technologies are not yet fully scaled. Technical failures or unexpected cost increases could leave these 8-to-10-year contracts unfulfilled.
There is also a contrast in how these investments are framed. While some view these as essential tools for net-zero goals, critics often argue that focusing on removal might reduce the urgency for companies to cut their actual emissions at the source.

Frequently Asked Questions
What is the Frontier coalition?
It is a group of companies, including Google, Stripe, and Anthropic, that funds the development of permanent carbon removal technologies through advance purchase agreements.

What is an offtake contract in carbon removal?
An offtake contract is a legal agreement to buy a specific amount of a product (in this case, carbon removal credits) in the future, providing the producer with financial stability.
Why is the AI industry involved in carbon removal?
AI companies like Anthropic use immense computing power, which generates significant carbon emissions. They invest in removal to offset their operational impact.
