1. UN/ECE Classification
of Emission Sources
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, 1999). Hence the fuel
definitions and the choice of base sector categories used in the NAEI often
reflect those in the DUKES publications.
The choice of non-combustion sources generally reflects the availability
of data on the emissions from specific activities.
The 1998 NAEI emission estimates are 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 below. In some cases the NAEI categories shown here are aggregates of more detailed emission sectors. The sectors are presented in this way in Table A1to allow an in depth understanding of the source sector content without presenting an excessive amount of information. In addition, the names of several NAEI categories have been changed to enable a fuller understanding by those not familiar with some of the nomenclature.
At the least detail level, there are 11 categories for the UN/ECE emission inventory format. These are as follow:-
01 Combustion in Energy Production & Transformation
02 Combustion in Commercial, Institutional & Residential & Agriculture
03 Combustion in Industry
04 Production Processes
05 Extraction & Distribution of Fossil Fuels
06 Solvent Use
07 Road Transport
08 Other Transport & Mobile Machinery
09 Waste Treatment & Disposal
10 Agriculture Forestry & Land Use Change
11 Nature
The allocation of a particular source to one of these sectors is well defined and given in more detail in Table A1. The majority of allocations are easy to understand. For example, emissions arising from fuel combustion in the manufacture of glass will come under “03 Combustion in Industry”. Emission arising from the manufacture/handling of the glass material itself and the raw materials will come under “04 Production Processes”.
