Under the 12-year agreement, Microsoft will purchase 2.85 million soil carbon removal credits from Indigo, supporting thousands of American farmers across millions of U.S. acres
BOSTON, Jan. 15, 2026 — Indigo Carbon PBC today announced one of the largest soil carbon deals to date. Under the 12-year agreement, Microsoft will acquire 2.85 million credits generated under the Carbon by Indigo program, Indigo’s U.S.-based initiative, highlighting regenerative agriculture’s role in high-integrity carbon removals.
As Indigo and Microsoft’s third transaction, this deal builds on prior purchases of 40,000 tonnes in 2024 and 60,000 tonnes in 2025, emphasizing Microsoft’s dedication to achieving carbon negativity by 2030 and Indigo’s leading position in providing scalable, high-integrity soil carbon removals.
Regenerative agriculture practices have been acknowledged by governments and climate organizations as a valuable means for carbon removal, capable of removing over 3.5 gigatons of carbon dioxide equivalent annually* besides enhancing soil health, boosting crop resilience and yields, and expanding local investment. Amid growing water scarcity, regenerative agriculture programs also provide support to rural communities with significant co-benefits such as improved water infiltration and conservation.
“Microsoft’s purchase showcases the transformative power of regenerative agriculture to support watersheds, farming communities, and advance global net-zero objectives,” stated Meredith Reisfield, Senior Director of Policy, Partnerships and Impact at Indigo. “Indigo is proud to be a catalyst in today’s soil carbon market, with our long history of collaborating with farmers and proven impact, having already saved 64 billion gallons of water and issued nearly one million tonnes of CO₂e carbon removal credits since 2018.”
In a time when farmers face increasing economic and environmental pressures, this deal provides significant financial incentives for adopting and expanding regenerative practices, enhancing farm resilience and creating new revenue streams for farmers. Indigo is proud to work with farmers across eight million acres, having paid farmers $40 million in total across all Indigo programs to date, independent of government funds.
“Microsoft is satisfied with Indigo’s approach to regenerative agriculture that delivers measurable results via verified credits and payments to growers, while advancing soil carbon science through advanced modeling and academic partnerships. Indigo is strengthening the carbon market through their commitment to enhancing project quality, advocating for the improvement of third-party standards, and producing high-integrity carbon removal credits,” commented Phillip Goodman, Director of Carbon Removal at Microsoft.
This agreement is also among the first soil carbon deals to include credits approved under the Integrity Council for the Voluntary Carbon Market’s (ICVCM) Core Carbon Principles. Leveraging peer-reviewed research, on-the-ground science, and cutting-edge remote sensing and machine learning, Indigo has issued 927,296 carbon removal and reduction credits from CAR1459 using the Climate Action Reserve’s Soil Enrichment Protocol (SEP). Indigo has implemented measures to reduce reversal risk over the 40-year durability term agreed with Microsoft, in addition to the SEP’s 100-year monitoring and reversal compensation obligations.
