2.5.4 SO , NO , NMVOC and CO<br />

2 X<br />

Emission factors for SO , NO , NMVOC and CO are listed in Appendix 3A-4. The<br />

2 X<br />

appendix includes references and time-series.<br />

The emission factors refer to:<br />

• The EMEP/Corinair Guidebook (EMEP/Corinair 2004)<br />

• The IPCC Guidelines, Reference Manual (IPCC 1996)<br />

• Danish legislation:<br />

° Miljøstyrelsen 2001 (Danish Environmental Protection Agency)<br />

° Miljøstyrelsen 1990 (Danish Environmental Protection Agency)<br />

° Miljøstyrelsen 1998 (Danish Environmental Protection Agency)<br />

• Danish research reports including:<br />

° An emission measurement program for decentralised CHP plants (Nielsen &<br />

Illerup 2003)<br />

° Research and emission measurements programs for biomass fuels:<br />

− Nikolaisen et al., 1998<br />

− Jensen & Nielsen, 1990<br />

− Dyrnum et al., 1990<br />

− Hansen et al., 1994<br />

− Serup et al., 1999<br />

° Research and environmental data from <strong>the</strong> gas sector:<br />

− Gruijthuijsen & Jensen 2000<br />

− Danish Gas Technology Centre 2001<br />

• Calculations based on plant-specific emissions from a considerable number of<br />

power plants (Nielsen 2003).<br />

• Calculations based on plant-specific emission data from a considerable number of<br />

municipal waste incineration plants. These data refer to annual environmental reports<br />

published by plant operators.<br />

• Sulphur content data from oil companies and <strong>the</strong> Danish gas transmission company.<br />

• Additional personal communication.<br />

Emission factor time-series have been estimated for a considerable number of <strong>the</strong><br />

emission factors. These are provided in Appendix 3A-4.<br />

2.6 Disaggregation to specific industrial subsectors<br />

The national statistics on which <strong>the</strong> emission inventories are based do not include a<br />

direct disaggregation to specific industrial subsectors. However, separate national<br />

statistics from Statistics Denmark include a disaggregation to industrial subsectors.<br />

This part of <strong>the</strong> energy statistics is also included in <strong>the</strong> official energy statistics from<br />

<strong>the</strong> Danish Energy Authority.<br />

Every o<strong>the</strong>r year Statistics Denmark collects fuel consumption data for all industrial<br />

companies of a considerable size. The deviation between <strong>the</strong> total fuel consumption<br />

from <strong>the</strong> Danish Energy Authority and <strong>the</strong> data collected by Statistics Denmark is<br />

ra<strong>the</strong>r small. Thus <strong>the</strong> disaggregation to industrial subsectors available from Statistics<br />

Denmark can be applied for estimating disaggregation keys for fuel consumption and<br />

emissions.<br />

The industrial fuel consumption is considered in three aspects:<br />
