European measurement programmes; see IFEU (2004) and Winther et al.
(2006). The NMVOC/CH4 split is taken from USEPA (2004).
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.13.
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.15 for 2010. 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.10. For more details regarding
the use of these factors, please refer to paragraph 3.1.4 or Winther et
al. (2006).
