Nitrous oxide gas, N(2)O, has a dual impact on climate, acting as a greenhouse gas and also causing depletion of ozone in the stratosphere, after conversion to NO. Estimates of nitrous oxide emissions from fossil fuel combustion made prior to June 1988 appear to be wrong, for two main reasons: - due to ignorance of the N(2)O artefact occurring in stored grab samples containing NO and SO(2), the emission from stationary combustion facilities has been over-estimated; - the nitrous oxide emission from automotive sources has been underestimated, mainly because the increase of emissions from gasoline engines equipped with three-way catalysts (particularly aged ones) has not been taken into account. A re-evaluation of the contribution of fossil fuel combustion to the total annual nitrous oxide emission is presented, based on a critical examination of the reliability of previous data. The report also includes an overview of available information on nitrous oxide formation and destruction mechanisms.
