Microsoft has announced a major step toward its 2030 climate goal of becoming carbon negative by entering into a decade-long agreement with Exomad Green to remove 1.24 million tonnes of CO₂ using biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More. This agreement represents the largest biochar-based carbon removal deal ever signed and underscores the growing role of durable carbon removal technologies in global climate strategies.

Biochar, a stable carbon-rich material created by heating biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More without oxygen, is valued for its long-term sequestration potential and ability to improve soil quality. Under this agreement, Exomad Green will produce biochar using waste biomass, primarily forestry residues that would otherwise be burned, thereby avoiding local air pollution and reducing fire risks.

To ensure transparency and credibility, each tonne of CO₂ removed will be tracked through Carbonfuture’s Monitoring, Reporting, and Verification platform, MRV+. The system aligns with the Puro.earth Biochar Methodology, providing independent certification and reinforcing the integrity of the removal process.

The initiative supports Exomad Green’s ambition to sequester one million tonnes of CO₂ annually by 2027. As of April 2025, the company holds 27% of the durable carbon removal market and has already delivered over 120,000 tonnes of carbon sequestration. This new agreement with Microsoft builds on a prior transaction in 2023 and signals deeper collaboration between the two companies, supported by Carbonfuture’s digital infrastructure.

In addition to climate impact, the project emphasizes community and environmental benefits. The newly established Forest Monitoring Center ensures sustainable sourcing of biomass and upholds ethical standards throughout the supply chain. Locally, over 250,000 people in Bolivia’s Concepción and Riberalta regions stand to benefit from improved soil conditions, enhanced agricultural productivity, and reduced pollution.

With expanded production capacity and more facilities underway, Exomad Green is positioning itself as a leader in industrial-scale biochar deployment. The deal with Microsoft not only demonstrates the readiness of biochar for large-scale application but also sets a precedent for future carbon removal initiatives with strong sustainability and social impact credentials.
