The GAP manual provides inventory methods for estimating emissions from numerous sources, including: fuel combustion and transformation; fugitive emissions from fuels; industrial process emissions; and emissions from solvents, agriculture, vegetation fire, forestry and the disposal of wastes. Several air pollutants are covered, too. An Excel workbook has been prepared as a companion to the GAP manual for use as a tool in preparing national inventories.
