Biochar, a charcoal made from heating discarded organic materials such as crop residues, offers a path to lowering atmospheric carbon dioxide (CO2). New maps, made from a first-of-its-kind high-resolution global dataset of crop residues, reveal areas where the residues may be sustainably used to produce biochar. The research finds that 12 countries have the technical ability to sequester over 20% of their current total greenhouse gas emissions by converting crop residues to biochar. Bhutan leads the way with the potential to sequester 68% of its emissions in the form of biochar, followed by India, at 53%. The study, “Potential for…
