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, 2017) [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, 2017) [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, 2017b) (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.

1 due to lack of better information: similar EF are applied for fossil diesel oil and biodiesel
2 country-specific tier1 values from (ifeu, 2017b) [3]
3 EF(PM2.5) also applied for PM10 and TSP (assumption: > 99% of TSP from diesel oil combustion consists of PM2.5)

For tier1 default values applied to NRMM in 1.A.2.g vii, 1.A.4.a ii, b ii and c ii as well as 1.A.5.b for emissions of heavy metals and POPs, please refer to the superordinate chapter linked above.

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

Emission Factors:
In addition to the revised activity data, several emission factors have been revised.
Here, smaller changes occur to the country-specific values from TREMOD MM.

Much stronger changes occur to the emission factors for heavy metals which have been replaced with the revised EF provided for NFRs 1.A.3.bi-iv within the EMEP Guidebook 2016 (July 2017 version)!
In the Guidebook, separate EFs for heavy-metal exhaust emissions from fuel combustion and engine wear on the one hand and from co-incinerated lubricants on the other hand are presented.
Although the EMEP Guidebook gives no clear instruction, HM emissions from the unintended co-incineration of lubricants in vehicles and machinery are allocated under NFR 2.G - Other product use.
