Google has signed its largest carbon-removal purchase to date with Terradot for a southern Brazilian rice-farm project that combines methane avoidance with permanent carbon dioxide removal. The agreement is notable not simply for its size, but for pairing two climate interventions with different timelines—and for putting them on the same agricultural landscape. 11

The deal in numbers
The project will operate across more than 200,000 hectares of rice farms in Rio Grande do Sul, Brazil. Google has agreed to purchase two distinct forms of climate impact:
- 1 million metric tons of methane-elimination impact by 2030, expressed as CO₂-equivalent using a 20-year global-warming-potential basis.
- 1 million metric tons of permanent carbon removal by 2040.
That makes 2 million metric tons of combined targeted impact, but the figures should not be treated as a single, interchangeable pool of credits. Methane avoidance and carbon removal have different mechanisms, time horizons, and measurement requirements. 11

Google and Terradot describe the effort as the largest enhanced rock-weathering project to date and the first project at this scale to combine rice-methane mitigation with carbon removal. 11

How the two interventions work
1. Alternate wetting and drying cuts rice methane
Rice paddies are commonly flooded. Under the project’s alternate wetting and drying (AWD) approach, fields are periodically drained rather than kept continuously flooded. The change is intended to reduce methane emissions associated with rice cultivation; the methane-elimination credits are the agreement’s near-term component. 6
11
2. Enhanced rock weathering is intended to remove CO₂
The carbon-removal component uses enhanced rock weathering (ERW). Terradot applies crushed reactive rock to agricultural land to accelerate a natural weathering process in which minerals absorb carbon dioxide. The agreement characterizes the resulting CO₂ removal as permanent. 11
13
The value of the pairing is timing: methane action is designed to reduce near-term warming impact, while carbon removal addresses carbon dioxide already in the atmosphere and intended to persist over much longer periods. Google explicitly frames the purchase around both near-term temperature impact and durable removal. 11
Why this project matters
Most carbon-market projects focus on a single greenhouse gas or a single credit type. This agreement instead creates separate purchasing commitments for avoided methane and removed CO₂ on rice farms. If it works as intended, it could offer a model for agricultural climate projects that do not force a choice between fast methane reductions and long-duration carbon removal. 11
13
It is also a major scale test. A project covering more than 200,000 hectares moves ERW and rice-methane practices beyond smaller demonstrations. That scale raises the stakes for monitoring: the eventual climate value depends on whether the methane reductions and carbon removal can be credibly quantified, independently verified, and maintained through farm-level deployment.
Cost remains undisclosed—and verification is a central challenge
Google and Terradot did not disclose the price of the new agreement. Reporting on Terradot’s earlier public deal described a roughly $300-per-ton price for 90,000 tons, above the often-cited $100-per-ton level associated with wider market adoption. Terradot has said the new project should cost less than earlier deals but is not yet expected to reach that benchmark; verification costs are a major constraint. 19
24
That makes the Brazil project more than a credit-purchase announcement. It is a test of whether a large agricultural deployment can lower the cost and improve the operational repeatability of measuring both avoided methane and permanent CO₂ removal.
What happens next
The companies say the Brazilian program could ultimately be expanded across Brazil’s rice-growing areas and replicated in other rice-producing countries, including India and Vietnam. Terradot plans pilots in multiple countries in 2026 and commercial scale-up in 2028. 19
22
For now, those are expansion plans rather than delivered outcomes. The headline commitment is substantial, but the real measure of success will be whether the project produces its promised 1 million tons of methane-elimination impact by 2030 and 1 million tons of permanent CO₂ removal by 2040 with credible verification. 11
