Climate change mitigation not only requires reductions of greenhouse gas emissions, but also withdrawal of carbon dioxide (CO 2 ) from the atmosphere. Here we review the relationship between emissions reductions and CO 2 removal by biochar systems, which are based on pyrolysing biomass to produce bi...
