Carbon sequestration

Biochar is a powerful carbon sink, capable of sequestering CO2 in the soil or materials for over 1,000 years. One ton of biochar can store between 2 to 3 tons of CO2 equivalent, enabling the generation of carbon credits on the voluntary market.

We use Cula.tech as our dMRV (digital measuring, reporting, and verifying software) to accurately track the carbon sequestration of our biochar.

We are Puro.Earth certified, ensuring high-quality carbon dioxide removal (CDR) with trusted and verifiable standards. Microsoft has already committed to purchasing carbon credits from the Carbonity project.
