Annual Danish informative inventory report to UNECE. Emission ...

For national sea transport and fisheries, the NOx emission factors predominantly
come from the engine manufacturer MAN Diesel, as a function
of engine production year. The CO, VOC and TSP emission factors
come from the Danish TEMA2000 emission model (Trafikministeriet,
2000), whereas the PM10 and PM2.5 size fractions are obtained from
MAN Diesel.
Specifically for the ferries used by Mols Linjen new NOx, VO and CO
emission factors are provided by Kristensen (2008), originating from
measurement results by Hansen et al. (2004), Wismann (1999) and PHP
(1996).
For ship engines VOC/CH4 splits are taken from EMEP/EEA (2009),
and all emission factors are shown in Annex 2.B.12.
The source for aviation (jet fuel) emission factors is the EMEP/EEA
guidebook (EMEP/EEA, 2009).
For all sectors, emission factors are given in CollectER format in Annex
2.B.14 for 2009. Table 3.38 shows the emission factors for SO2, NOX,
NMVOC, CO, NH3 and TSP in CollectER format used to calculate the
emissions from other mobile sources in Denmark.

The emission effects of engine wear are taken into account for diesel
and gasoline engines by using the so-called deterioration factors. For
diesel engines alone, transient factors are used in the calculations, to account
for the emission changes caused by varying engine loads. The
evaporative emissions of NMVOC are estimated for gasoline fuelling
and tank evaporation. The factors for deterioration, transient loads and
gasoline evaporation are taken from IFEU(2004), and are shown in Annex
2.B.9. For more details regarding the use of these factors, please refer
to paragraph 3.1.4 or Winther et al. (2006).
