For non-road machinery, the EU directive 2003/17/EC gives a limit value of
50 ppm sulphur in diesel (from 2005).

The SO2 emission factors are fuel related, and rely on the sulphur contents
given in the relevant EU fuel directives or in the Danish legal announcements.
However, for jet fuel the default factor from IPCC (1996) is used.
Road transport diesel is assumed to be used by engines in military and railways,
and road transport gasoline is assumed to be used by non road working
machinery and recreational craft. Hence, these types of machinery have
the same SO2 emission factors, as for road transport.
For all mobile sources, the emission factor source for NH3, heavy metals and
PAH is the EMEP/EEA guidebook (EMEP/EEA, 2009). The heavy metal
emission factors for road transport and other mobile sources except national
sea transport and fisheries originate from Winther and Slentø (2010). For
civil aviation jet fuel, no heavy metal emission factors are proposed due to
lack of data.
For military ground equipment, aggregated emission factors for gasoline
and diesel are derived from road traffic emission simulations. For piston engine
aircraft using aviation gasoline, aggregated emission factors for conventional
cars are used.
For railways, specific Danish measurements from the Danish State Railways
(DSB) (Delvig, 2011) are used to calculate the emission factors of NOx, VOC,
CO and TSP, and a NMVOC/CH4 split is made based on expert judgment.
For agriculture, forestry, industry, household gardening and inland waterways,
the NOx, VOC, CO and TSP emission factors are derived from various
