Denmark's National Inventory Report 2005 - Submitted under the ...

The fuel consumption of area sources is calculated as total fuel consumption minus fuel consumption
of large point sources.
Emissions from non-energy use of fuels have not been included in the Danish inventory, to date,
but the non-energy use of fuels is, however, included in the reference approach for Climate Convention
reporting. The Danish energy statistics include three fuels used for non-energy purposes:
Bitumen, white spirit and lube oil. The fuels used for non-energy purposes add up to less than 2%
of the total fuel consumption in Denmark.
In Denmark all municipal waste incineration is utilised for heat and power production. Thus, incineration
of waste is included as stationary combustion in the IPCC Energy sector (source categories
1A1, 1A2 and 1A4).
Fuel consumption data is presented in Chapter 3.2.1.2.
3.2.2.4 Emission factors
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 EMEP/Corinair Guidebook (EMEP/Corinair 2004) and IPCC Reference
Manual (IPCC 1996).
A complete list of emission factors including time-series and references is shown in Annex 3A.
CO 2
The CO 2 emission factors applied for 2003 are presented in Table 3.11. For municipal waste and
natural gas, time-series have been estimated. For all other fuels the same emission factor is applied
for 1990-2003.
In reporting to the Climate Convention, the CO 2 emission is aggregated to five fuel types: Solid
fuel, Liquid fuel, Gas, Biomass and Other fuels. The correspondence list between the NERI fuel
categories and the IPCC fuel categories is also provided in Table 3.11. The emission factors are
further discussed in Annex 3A.
The CO 2 emission from incineration of municipal waste (94.5 + 17.6 kg/GJ) is divided into two
parts: The emission from combustion of the plastic content of the waste, which is included in the
national total, and the emission from combustion of the rest of the waste – the biomass part, which
is reported as a memo item. In the IPCC reporting, the CO 2 emission from combustion of the plastic
content of the waste is reported in the fuel category, Other fuels. However, this split is not applied
in either fuel consumption or other emissions, as it is only relevant for CO 2 . Thus, the full
consumption of municipal waste is included in the fuel category, Biomass, and the full amount of
non-CO 2 emissions from municipal waste combustion is also included in the Biomass-category.
The CO 2 emission factors have been confirmed by the two major power plant operators, both directly
(Christiansen, 1996 and Andersen, 1996) and indirectly, by applying the NERI emission factors
in the annual environmental reports for the large power plants and by accepting use of the
NERI factors in Danish legislation.
The current Danish legislation concerning CO 2 emission from power plants in 2003 and 2004 (Lov
nr. 376 1999) is based on standard CO 2 emission factors for each fuel. Thus, so far power plant operators
have not been encouraged to estimate CO 2 emission factors based on their own fuel analysis.
In future legislation (Lov nr. 493 2004) operators of large power plants are obliged to verify the
applied emission factors, which will lead to the availability of improved emission factors for na-
