Due to the scarce data available and the very low consumption of town gas
compared to consumption of natural gas, the methodology will be applied
unchanged in future inventories.

For each fuel and SNAP category (sector and e.g. type of plant), a set of general
area source emission factors has been determined. The emission factors
are either nationally referenced or based on the international guidebooks:
EEA/CORINAIR Guidebook (EEA, 2009) 4 and IPCC Reference Manual
(IPCC, 1996).
A complete list of emission factors including time series and references is
provided in Annex 2A-4.

Emission factors for SO2, NOx, NMVOC and CO are listed in Annex 2A-4.
The appendix includes references and time series.
The emission factors refer to:
• The EMEP/CORINAIR Guidebook (EEA, 2007 and EEA, 2009).
• The IPCC Guidelines, Reference Manual (IPCC, 1996).
• Danish legislation:
• Miljøstyrelsen, 2001 (DEPA).
• Miljøstyrelsen, 1990 (DEPA).
• Miljøstyrelsen, 2003 (DEPA).
• Danish research reports including:
• Two emission measurement programs for decentralised CHP plants
(Nielsen et al. 2010; Nielsen & Illerup, 2003).
• Research and emission measurements programs for biomass fuels:
• Nikolaisen et al. (1998).
• Jensen & Nielsen (1990).
• Serup et al. (1999).
• Christiansen et al. (1997).
• Research and environmental data from the gas sector:
• Gruijthuijsen & Jensen (2000).
• Danish Gas Technology Centre (DGC) (2001).
• Wit & Andersen (2003).
• Aggregated emission factors for residential wood combustion based on
technology distribution (Nielsen & Hessberg, 2011) and technology specific
emission factors (EEA 2009; DEPA 2010). For NMVOC the emission
factors also refer to Pettersson et al. (2011).
• Calculations based on plant-specific emissions from a considerable number
of power plants.
• Calculations based on plant-specific emission data from a considerable
number of waste incineration plants. These data refer to annual environmental
reports published by plant operators.
• Sulphur content data from oil companies and the Danish gas transmission
company, Energinet.dk.
• Additional personal communication.
The emission factors for NMVOC that are not nationally referenced all refer
to EEA (2009).
