NFR-Code Name of Category Method AD EF Key Category 1
1.A.3.d ii National Navigation (Shipping) T1, T2, T3 NS, M CS, D, M L & T: NOx, PM10 & PM2.5
including emission from
1.A.3.d ii (a) National Maritime Navigation T1, T2, T3 NS, M CS, D, M not included separately in key-category analysis
1.A.3.d ii (b) National Inland Navigation T1, T2 NS, M CS, D, M not included separately in key-category analysis


Activity data

As described for the over-all sector 1.A.3.d and all other navigational activities here, specific fuel consumption data for NFR 1.A.3.d ii is included in the primary fuel deliveries data provided in NEB lines 6 ('International Maritime Bunkers') and 64 ('Coastal and Inland Navigation') [1].

Here, the annual fuel consumption for domestic maritime navigation are modelled within [5] based on AIS data and deduced from NEB lines 6 and 64 respectively, depending on whether or not a certain ship is registered by the International Maritime Organization (IMO). Here, fuels consumed by large, IMO-registered and sea-going ships and vessels are included in NEB line 6 whereas fuels consumed by smaller ships without IMO-registration are included in NEB line 64. After these deductions, the amounts of fuels remaining in NEB 64 are allocated to domestic inland navigation.

Emission factors

For information on the specific EF applied to 1.A.3.d ii (a) - Domestic Maritime Navigation and 1.A.3.d ii (b) - Domestic Inland Navigation, please refer to the sub-chapters linked above.

Discussion of emission trends

NFR 1.A.3.d ii is key category for emissions of NOx, PM2.5 and PM10.

For ammonia, NMVOC, and nitrogen oxides as well as carbon monoxide, emission trends more or less represent the trend in over-all fuel consumption. Nonetheless, for these pollutants, annual emission factors from TREMOD have been applied to national inland navigation, reflecting the technical development of the German inland navigation fleet.
In contrast, for the newly implemented reporting for emissions from national maritime navigation, constant tier1 values are applied at the moment, not taking into account any technical developments.

Regarding sulphur dioxide and particulate matter, emission trends also reflect the ongoing fuel-sulphur legislation.


Activity Data: Major changes result from the revision of the National Energy Balance 2015. In addition, changes for both years result from the revision of the BSH model [5] used for estimating the fuel consumption for domestic maritime navigation.

Uncertainty estimates for activity data of mobile sources derive from research project FKZ 360 16 023: "Ermittlung der Unsicherheiten der mit den Modellen TREMOD und TREMOD-MM berechneten Luftschadstoffemissionen des landgebundenen Verkehrs in Deutschland" by (ifeu & INFRAS, 2009) [7]. - For detailled information, please refer to the project's final report here (German version only!)

Planned improvements

With the next annual submission routine revisions of the models used for maritime and inland navigation are scheduled.
