Activity data

Subsector-specific consumption data is included in the primary fuel-delivery data are available from NEB line 67: 'Commercial, trade, services and other consumers' (AGEB, 2014) [1].

Table 1: Sources for primary fuel-delivery data
through 1994 AGEB - National Energy Balance, line 79: 'Haushalte und Kleinverbraucher insgesamt'
as of 1995 AGEB - National Energy Balance, line 67: 'Gewerbe, Handel, Dienstleistungen u. übrige Verbraucher'

Following the deduction of energy inputs for military vehicles as provided in (BAFA, 2014) [2], the remaining amounts of gasoline and diesel oil are apportioned onto off-road construction vehicles (NFR 1.A.2.g vii) and off-road vehicles in commercial/institutional use (1.A.4. ii) as well as agriculture and forestry (NFR 1.A.4.c ii) based upon annual shares derived from TREMOD-MM (ifeu, 2014b) (cf. NFR 1.A.4 - mobile).

Emission factors

The emission factors used here are of rather different quality:
For all main pollutants, carbon monoxide and particulate matter, annual IEF modelled within [3] are used, representing the sector's vehicle-fleet composition, the development of mitigation technologies and the effect of fuel-quality legislation.

In contrast, without country-specific information, regarding all heavy metals and POPs, tier1 values are applied. Here, EF for exhaust HMs and PAHs have been derived from (EMEP/EEA, 2016) [4].

The tier1 value apllied for PCDD/F has been derived from a study carried out by (Rentz et al., 2008) [5] for the German Federal Environment Agency.

For HCB and PCBs, no emission factors are available at the moment.

NOTE: As no such specific EF are available for biofuels, the values used for diesel oil are applied to biodiesel, too.
