Under sub-category 1.A.4.c ii (a) fuel combustion activities and resulting emissions from agricultural off-road vehicles and mobile machinery are reported.

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, 2019) ¹⁾.

Table 1: Sources for primary fuel-delivery data

Following the deduction of energy inputs for military vehicles as provided in (BAFA, 2019) 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. (2019b)) (cf. NFR 1.A.4 - mobile ]).

The emission factors applied here are of rather different quality: For all main pollutants, carbon monoxide and particulate matter, annual IEF modelled within TREMOD MM 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 and biofuels
² EF(PM_2.5) also applied for PM₁₀ and TSP (assumption: > 99% of TSP consists of PM_2.5)
³ estimated via a f-BCs as provided in ⁴⁾, 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

NOTE: With respect to the country-specific emission factors applied for particulate matter, given the circumstances during test-bench measurements, condensables are most likely included at least partly.footnote During test-bench measurements, temperatures are likely to be significantly higher than under real-world conditions, thus reducing condensation. On the contrary, smaller dillution (higher number of primary particles acting as condensation germs) together with higher pressures increase the likeliness of condensation. So over-all condensables are very likely to occur but different to real-world conditions. footnote

Revisions in activity data result from slightly adapted EBZ67 shares as well as the implementation of primary activity data from the now finalised NEB 2019.

In addition, all emission factors remain unrevised compared to last year's susbmission, emission estimates for the years as of 2015 change in accordance with the underlying activity data.
