Google has agreed to purchase 1 million carbon credits from Indian climate-tech startup Mitti Labs through 2030 in what the companies describe as the largest publicly announced deal for credits generated by reducing methane emissions from rice farming. The four-year agreement will cover farms in Karnataka, Andhra Pradesh and Telangana, reaching about 100,000 hectares at peak delivery. Farmers will be paid to reduce the time rice fields remain flooded, a practice Mitti Labs says can lower methane emissions by about 50% and irrigation-water use by about 40% without reducing yields. Financial terms were not disclosed. The deal comes as Google works toward net-zero emissions by 2030 while expanding artificial-intelligence infrastructure; its 2025 greenhouse-gas emissions rose 18% from a year earlier to about 14.5 million metric tons of carbon dioxide equivalent. Mitti Labs, founded in 2023 and based in New York and Bengaluru, uses a GeoAI platform combining satellite radar imagery and field measurements to monitor smallholder farms. Its credits can be issued under Gold Standard or Isometric after independent third-party verification. The startup currently works with more than 100,000 farmers, aims to reach millions by 2030, and plans to expand to the Philippines later this year and Indonesia and other Southeast Asian markets in 2027.
