Biochar, a type of carbonized biomass which can be produced from crop residues (CRs), offers a promising solution for carbon dioxide removal (CDR) when it is used to sequester photosynthetically fixed carbon that would otherwise have been returned to atmospheric CO₂ through respiration or combustion. By developing a comprehensive high spatial resolution global dataset of CR production, the authors show that, globally, CRs generate around 2.4 Pg C annually.
