The Emission Source Classification
The NAEI reports emissions from the combustion of fuels and non-combustion emissions from a range of sectors. The fuels data are taken from the Digest of UK Energy Statistics (DUKES), (DTI, 1998). Hence the fuel definitions and the choice of base sector categories used in the NAEI reflect those in DTI (1998). The choice of non-combustion sources generally reflects the availability of data on these emissions.
The 1997 NAEI is reported according to the UNECE/CORINAIR SNAP 94 Version 1.0 eleven sector classification which is less detailed than the NAEI base categories. A listing of the NAEI base categories and their mapping onto the UNECE/CORINAIR SNAP 94 categories is shown in Table A1.
