Ensuring Quality at Scale: Inside the 2025 Puro.earth Biochar Methodology

Biochar is scaling globally as one of the most mature and investable carbon removal pathways. Projects are now active in numerous countries, delivering both durable climate impact and co-benefits for soils, agriculture, and communities.

Puro.earth has been at the forefront of this growth, setting the benchmark for quality and trust through the world’s first methodology for biochar carbon removal. Over the past five years, the biochar ecosystem has transformed significantly: new actors have emerged, valuable operational insights have been gained, the voluntary carbon market has evolved, and scientific understanding of biochar persistence has advanced. The 2025 Edition of the Puro.earth Biochar Methodology brings these developments together into a more rigorous and forward-looking framework designed to uphold integrity as the market scales.
