Currently biomass burning accounts for 10% of global CH4 emissions and 1% of N2O
(Crutzen et al., 1990). Although current charcoal production activity could account for a
component of these emissions (Woolf, 2008), a general shift to pyrolysis-based systems
would decrease, if not eliminate, them. However, the net result with great expansion of
alternative bioenergy systems has not been assessed.
