“Climate change is a threat to civilization which must be tackled. Biochar offers a significant tool to reduce CO2 and GHG greenhouse gas emmissions— it has been estimated that, on a global scale, sustainable biochar production could reduce net emissions of GHGs by as much as 12% of current anthropogenic emissions.”
Also importantly is its extremely long lasting ability in boosting soil productivity.
