Biomass burning, largely resulting from the activities of humans, accounts for ~0.5 Tg N2O emissions each year. N2O emissions arising from biomass burning are a result of incomplete combustion, and significant amounts can be produced during large-scale burning of forests, savannah and grasslands.
An important source of N2O emission related to biomass burning is crop residue burning. The high nitrogen and water contents of many crop residues mean that the burning of such material can produce a relatively high percentage (around 1%) of the total emissions in the form of N2O.
Wood burning is used for domestic heating and cooking purposes and for charcoal production, and can also release significant amounts of N2O.
recent decades, and the widespread use of coal as power station fuel means that N2O emissions from this source should not be overlooked.
