Indigo Agriculture to Sell 2.85 Million Tonnes of Carbon Removal to Microsoft
January 15, 2026
Indigo Agriculture announced the largest soil carbon removal deal by tonnage to date: a 12-year agreement for Microsoft to purchase 2.85 million soil carbon removal credits. This is Microsoft's third transaction with Indigo, scaling up dramatically from prior purchases of 40,000 tonnes (2024) and 60,000 tonnes (2025).
The agreement is one of the first soil carbon deals to feature credits approved under the Integrity Council for the Voluntary Carbon Market's Core Carbon Principles, the global standard for high-integrity carbon credits. The deal supports thousands of American farmers across millions of U.S. acres.
Founded by TJHSST alum Geoffrey von Maltzahn through Flagship Pioneering, Indigo has paid farmers $40 million across all of its programs, with 75% of credit value going directly back to the farmer.
