Alphabet has backed its largest carbon removal project yet through Terradot, which plans to spread enhanced weathering material across more than 200,000 hectares of rice fields in Brazil. The project targets one million tons of methane abatement credits by 2030 and one million tons of carbon removal credits by 2040, roughly ten times the scale of earlier rock-weathering projects. Google also holds an equity stake in Terradot, so it is both a buyer and a financial backer of the technology. Costs remain a key question. A 2024 Terradot transaction implied a removal cost near $300 per ton, while developers see roughly $100 per ton as the level for broader adoption. The price of Alphabet's latest agreement has not been disclosed, which makes it hard to assess the direct financial return. The article also notes that Alphabet's share price sits well above its GF Value estimate, adding pressure on its large AI and infrastructure spending to generate durable growth.
