Record-Setting Agreement: Microsoft’s 1.24M-tonne biochar carbon removal deal with Exomad Green is the largest of its kind by volume.
Strategic Climate Action: The 10-year agreement supports Microsoft’s push to become carbon-negative by 2030 and sets a new bar for durable carbon removals.
Scalable Carbon Tech: Exomad Green to expand production and implement forest monitoring, benefiting 250,000+ people in Bolivia.
Microsoft has signed a landmark 10-year agreement with Bolivia-based Exomad Green to remove nearly 1.24 million tonnes of CO₂ via biochar—a move that marks the largest biochar carbon removal deal in history, both companies confirmed on May 21.
“This agreement helps us reach our goal of sequestering 1 million mtCO₂e annually by 2027,” said Diego Justiniano, CEO of Exomad Green.
The deal underscores Microsoft’s commitment to durable carbon removal technologies as part of its broader climate strategy to become carbon-negative by 2030. It also reinforces the company’s effort to power data centers with 100% zero-emission energy.
This is not the first collaboration between the two. Microsoft previously purchased 32,000 tonnes of biochar removal credits from Exomad in December 2023. The latest agreement significantly scales up that partnership, positioning both companies at the forefront of high-integrity, large-scale carbon removal.
Exomad Green is the world’s largest biochar producer, currently removing 120,000 mtCO₂e annually across two facilities. It is now building a third site, with two more in planning. The firm uses pyrolysis technology to convert sustainably sourced forestry residues—waste that would otherwise be incinerated—into biochar. This biochar is distributed to local farmers, where it remains in soil for centuries, enhancing both carbon storage and agricultural productivity.
“Through this carbon removal deal with Microsoft, we also intend to deliver co-benefits to more than 250,000 people in Riberalta, Concepcion, and nearby communities,” the company said in a statement.
The credits will be certified by Puro.earth, with Carbonfuture handling monitoring, reporting, and verification through its MRV+ digital platform. This ensures full traceability of each carbon credit from production to storage.
Additional features include the launch of a Forest Monitoring Center to track the origin of all biomass inputs, and regular quality testing to ensure biochar consistently meets international standards.
Biochar is gaining recognition as a viable carbon dioxide removal (CDR) pathway, alongside direct air capture, enhanced weathering, and reforestation. Unlike traditional offset strategies, CDR actively removes CO₂ from the atmosphere, offering long-term climate benefits.
The value of such credits is rising—Platts Tech Carbon Capture assessed biochar credits at $148/mtCO₂e on May 20, a three-month high.
This record-setting deal not only scales up durable CDR but also sets a blueprint for traceable, community-integrated climate solutions.
