10-year agreement with Liferaft highlights growing demand for durable climate solutions and sustainable agriculture
Redmond, Washington, 27 March 2026 – Microsoft has taken a major step forward in its climate strategy by signing a 10-year agreement with biochar company Liferaft to purchase one million carbon removal units. The deal is one of the largest of its kind and reflects the increasing importance of long-term, reliable carbon removal solutions in corporate sustainability efforts.
The carbon removal credits will be generated at Liferaft’s facilities in Iowa and Illinois. These sites will convert agricultural and municipal waste into biochar, a carbon-rich material that can store carbon in soil for hundreds of years. In addition to capturing carbon, biochar also improves soil quality, making it beneficial for farming and land management.
This agreement supports Microsoft’s broader goal of becoming carbon negative by 2030 and removing its historical emissions by 2050. The company continues to lead in the carbon removal market by investing in large-scale, long-term projects.
Biochar is gaining attention as a practical and scalable climate solution. It is produced through a process called pyrolysis, which heats biomass without oxygen, locking carbon into a stable form. Liferaft’s approach uses locally sourced materials, creating a circular system that reduces waste while supporting regional supply chains.
The project also focuses on economic impact. By working with local communities, Liferaft aims to create jobs, support farmers, and contribute to rural development alongside environmental goals.
The agreement was supported by Supercritical, a carbon removal marketplace that helps connect companies with verified projects. All carbon credits will undergo strict monitoring and third-party verification to ensure transparency and long-term impact.
As companies face increasing pressure to meet climate targets, there is a clear shift toward high-quality carbon removal solutions. Deals like this show how businesses are moving beyond short-term measures and investing in technologies that deliver lasting environmental and economic value.
