1.A.4 - Small Combustion: Mobile Sources (OVERVIEW)

Mobile sources reported under NFR 1.A.4 - Small combustion comprise of such versatile mobile equipment as forklifters (1.A.a ii), gasoline-driven lawn mowers used for gardening (1.A.4.b ii) over tractors in agriculture and harvesters and chain saws in forestry (1.A.4.c ii) to the German deep sea fishing fleet (1.A.4.c iii).

Primary activity data are available from National Energy Balances (NEBs) (AGEB, 2021) ¹⁾.

Here, aggregated data for NFRs 1.A.a ii,1.A.4.c ii and 1.A.2.g vii are included in line 67: 'Commercial, trade, services and other consumers'. In contrast, AD for is available directly from line 66: 'Households'. Furthermore, AD for is included partly in NEB lines 6: 'Maritime Bunkers' and 64: 'Coastal and inland navigation'.

Table 1 below tries to demonstrate the breaking-down of primary data in NEB line 67 onto NFRs 1.A.2.g vii, 1.A.4a ii and 1.A.4.c ii. For further information on the resulting specific shares as well as the fuel consumption in NFRs 1.A.4.b ii and 1.A.4.c iii please refer to the respective sub-chapters.

In a first step, annual fuel deliveries to the military as provided in (BAFA, 2021) ²⁾…

Table 2: Annual fuel deliveries to the military as included in NEB line 67, in terajoules

…are deduced from these primary AD, giving the remaining amounts of gasoline and diesel oil for NFRs 1.A.2.g vii, 1.A.a ii and 1.A.4.c ii:

As the National Enregy Balances provide no consumption data for LPG before 1995 and as part of the LPG provided in NEB line 67 is used for stationary combustion (whereas all diesel and gasoline fuels are allocated to mobile combustion), activity data for LPG used in in NRMM are taken directly from TREMOD MM (Knörr et al. (2021b)) ³⁾.

In another step, the following sub-sectors specific annual percentual contributions to NEB line 67 as computed within TREMOD-MM are apllied to these primary AD to deduce sub-sectors specific AD.

Primary activity data for 2018 and 2019 were revised in accordance with the final National Energy Balance 2019 and the revision of gasoline used in military ground vehicles.
