Puro.earth consults on updated methodology for mineral carbonation credits

Puro.earth has opened a public consultation in Finland for revisions to its Carbonated Materials (CM) methodology under the Puro Standard. The update aims to enhance quantification rigour, transparency, and operational clarity for durable mineral carbonation practices. Proposed changes include a more explicit framework for managing quantification uncertainty and improved guidelines for data publication. This initiative seeks to strengthen the crediting framework for carbon stored in mineral-based materials for over 1,000 years, supporting the scalability and credibility of carbon dioxide removal projects.
