Methodology
Activity data
Primary activity data (PAD) are taken from National Energy Balances (NEBs) line 67: 'Commercial, trade, services and other consumers' (AGEB, 2022) 1).
Following the deduction of energy inputs for military vehicles as provided in (BAFA, 2022) 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 (Knörr et al. (2022b) 3) (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, annually changing values computed within TREMOD MM (Knörr et al. (2022b)) 4) are used, representing the development of mitigation technologies and th effect of fuel-quality legislation.

1 due to lack of better information: similar EF are applied for fossil and biofuels
2 from fuel combustion
3 from gasoline evaporation
4 EF(PM2.5) also applied for PM10 and TSP (assumption: > 99% of TSP consists of PM2.5)
5 estimated via a f-BCs as provided in 5), Chapter 1.A.2.g vii, 1.A.4.a ii, b ii, c ii, 1.A.5.b i - Non-road, note to Table 3-1: Tier 1 emission factors for off-road machinery
6 from leaded gasoline (until 1997)
With respect to the emission factors applied for particulate matter, given the circumstances during test-bench measurements, condensables are most likely included at least partly. 1)
For information on the emission factors for heavy-metal and POP exhaust emissions, please refer to Appendix 2.3 - Heavy Metal (HM) exhaust emissions from mobile sources and Appendix 2.4 - Persistent Organic Pollutant (POP) exhaust emissions from mobile sources.
Recalculations
Revisions in activity data result from (i) a revision of the underlying National Energy Balances 2003 to 2021 as well as (ii) strongly revised consumption data for agricultural mobile sources: Here, as the over-all amounts of fuels to be distributed on the different non-road mobile machinery (NRMM) is provided in NEB line 67, the strongly increased AD applied for agricultural mobile sources results in decreased amounts of diesel oil allocatd to both mobile sources in forestry and construction/demolitiion (see chapter on NFR 1.A.2.g vii).

In parallel to these revisions in activity data, several emission factors have been unrevised within TREMOD MM. Here, the most relevant chang occurs for NMVOC emissions from both the combustion and evaporation of gasoline, where in the last submissions, emission factors for these to emission sources were confused.
