Artisanal Biochar Estimated Rating Framework

Biochar projects remove carbon dioxide by converting biomass into a stable,carbon-rich solid through pyrolysis and applying it to soils, where the carbon persistsfor centuries. Version 1.0 of Sylvera’s Artisanal Biochar Estimated Rating frameworkcovers small-scale, distributed production, typically using rudimentary pyrolysis. AnEstimated Rating is an indicative range, such as A–BBB, derived from a limited set ofmaterial data points in public project documentation. It is not reviewed by a RatingsCommittee, not monitored and produced without developer engagement.
