The Intergovernmental Panel on Climate Change (IPCC) reported Biochar as a key technology for reaching low carbon dioxide atmospheric concentration targets. The negative emissions that can be produced by Bio-energy with carbon capture and storage (BECCS) has been estimated by the Royal Society to be equivalent to a 50 to 150 ppm decrease in global atmospheric carbon dioxide concentrations. Annual net emissions of carbon dioxide (CO2), methane and nitrous oxide could be reduced by a maximum of 1.8 Pg CO2-C equivalent (CO2-Ce) per year (12% of current anthropogenic CO2-Ce emissions; 1 Pg=1 Gt), and total net emissions over the course of a century by 130 Pg CO2-Ce, without endangering food security, habitat or soil conservation.

Biochar researchers have expanded their research to around 350 sites on the North Coast, including coffee, macadamia and sugar cane farms.
