BIOCHAR
climate impact assessment

August 2008

Carbon sequestration in soil has significant potential.

Biochar, produced in pyrolysis of crop residues, forestry wastes and animal manures, can restore soil fertility while storing carbon for centuries to millennia.

Biochar helps soil retain nutrients and fertilizers, reducing emissions of greenhouse gases such as N2O.

Replacing slash-and-burn agriculture with slash-and-char, using agriculture and forestry wastes for

biochar production
can provide CO2 drawdown
of ~8 ppm or more
in half a century
.
