Indigo accelerates soil carbon removals for Microsoft in second collaboration

Boston, MA – May 27, 2025 – Indigo today announced that Microsoft has committed to purchase 60,000 soil carbon

credits from the company’s fourth and largest carbon crop, issued in April by the Climate Action Reserve. This builds

on Microsoft's initial purchase of 40,000 credits last June, expanding on their portfolio of high-integrity removals.

To date, Indigo's carbon program has generated nearly a megaton of carbon impact and prevented over 64B gallons

of surface water runoff. The company's latest ‘carbon crop' will channel tens of millions of dollars from private

buyers to support regenerative farmers across the U.S. 75% of carbon sales will directly pay farmers per Indigo’s

standard program, accelerating farmers’ adoption of regenerative agriculture. The project design and adherence to

stringent registry requirements ensure that carbon stays in the soil for many decades, delivering a long-term

solution that carbon credit buyers can trust year-over-year.

This purchase marks a critical step forward in establishing a market for high-quality removals in soils. Indigo’s peer-reviewed research and measurement, reporting and verification (MRV) tools, the scale Indigo’s program reached in

its latest issuance, and Microsoft’s transaction provide strong evidence of the contribution of soil carbon credits to

high-integrity climate action portfolios.

“When Microsoft, recognized as the major driver behind the carbon removals market, invests in Indigo’s carbon

credits, it affirms their confidence in our science, team, and technology,” said Dean Banks, CEO, Indigo Ag. “Our

microbial and sustainability portfolio spans 20 million acres across 15 countries, and this deal underscores the trust

in farmers’ hard work to create a healthy and resilient agri-food system.”

“Indigo’s work to create resilient farms and secure watersheds across the U.S. delivers measurable climate benefits

as well as improved soil and water health and new economic development opportunities in rural communities,” said

Brian Marrs, Senior Director of Energy and Carbon Removal, Microsoft. “We conduct extensive due diligence when

choosing projects for our portfolio, and are pleased to support this project as part of Microsoft’s broader portfolio of

high-quality carbon removal solutions. The collaboration aims to protect the economic security of our agri-food

system with a measurable and scalable approach to nature-based carbon removal.”

Other buyers of Indigo’s recently issued credits include HubSpot, which purchased via Watershed.
