In this series, DeSmog digs into the promise and peril of biochar as a solution to climate change. Authored by Steve Horn, this investigative report is the result of a years-long probe into biochar, geoengineering, and whether it can put a dent in climate change. Learn about the science — and lack thereof — supporting biochar’s carbon sequestration potential, the major players and their connections to Big Oil, and the rush to deploy large-scale biochar projects as part of questionable carbon offsets programs. Read the whole series below.
