Microsoft Deepens Commitment to Carbon Removals

Microsoft has signed a landmark 10-year deal with Bolivia-based Exomad Green to purchase nearly 1.24 million metric tons of biochar carbon removal credits, marking the largest biochar removals agreement ever by volume, according to a joint statement released on May 21.

The deal builds on Microsoft’s carbon-negative goal by 2030, which includes both offsetting emissions and sourcing 100% zero-emission power for its global data center operations. It also follows an earlier 32,000 mtCO2e biochar purchase from Exomad Green in December 2023.

Scaling Biochar as a Climate Solution

“This deal will help us reach our goal of sequestering 1 million mtCO2e annually by 2027,” said Diego Justiniano, CEO of Exomad Green.

The company operates two biochar plants in Bolivia, currently removing 120,000 mtCO2e per year. A third facility is under construction, with two more in planning stages.

Biochar, produced through pyrolysis of agricultural hardwood residues, stores carbon in a stable form in soil for centuries — while also enhancing soil quality. Exomad Green’s credits will be certified by Puro.earth, with Carbonfuture overseeing monitoring, reporting, and verification.

Biochar Market Heats Up

The Platts Tech Carbon Capture price for biochar removals surged to a three-month high of $148/mtCO2e as of May 20, according to S&P Global Commodity Insights — highlighting rising demand for technology-based carbon removal.

CDR, or carbon dioxide removal, includes strategies that actively extract CO2 from the atmosphere, such as biochar, direct air capture, and biomass storage — distinct from emission avoidance tactics.

This deal positions Microsoft at the forefront of long-term climate solutions while enabling Exomad Green to significantly scale its carbon sequestration footprint.
