Method

Activity data

Fuel consumption in national maritime navigation (e.g. for trips between German sea harbours) is estimated based on AIS data within a model maintained at the Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH). [1]

Emission factors

The emission factors applied here are derived from different sources and therefore are of very different quality.

For the main pollutants, country-specific implied values are used, that are based on tier3 EF included in the BSH model [1] which mainly relate on values from the EMEP/EEA guidebook 2016 [2]. These modelled IEFs take into account the ship specific information derived from AIS data as well as the mix of fuel-qualities applied depending on the type of ship and the current state of activity.

Here, for sulphur dioxide and particulate matter, annual values are available representing the impact of fuel sulphur legislation.
In addition, regarding SOx, the increasing operation of so-called scrubbers in order to fullfil emission limits especially within SECA areas is reflected for heavy fuel oil.

1 due to lack of better information: similar EF are applied for diesel oil and biodiesel
2 ratios PM2.5 : PM10 : TSP derived from the tier1 default EF as provided in [2], chapter: 1.A.3.d.i, 1.A.3.d.ii, 1.A.4.c.iii Navigation, Tables 3-1 & 3-2
3 estimated from f-BCs as provided in [2]: f-BC (HFO) = 0.12, f-BC (MDO/MGO) = 0.31 as provided in [2], chapter: 1.A.3.d.i, 1.A.3.d.ii, 1.A.4.c.iii Navigation, Tables 3-1 & 3-2

For heavy metals and PCDD/F, PAHs, HCB and PCBs, similar tier1 values are applied for all navigation sub-categories. For details please refer to the superordinate chapter on 1.A.3.d linked here.

Discussion of emission trends

Sub-sector 1.A.3.d ii (a) is not considered separately within the key category analysis.

Basically, for all unregulated pollutants, emission trends directly follow the trend in over-all fuel consumption:

For sulphur dioxide and particulate matter, emission trends not only follow the trend in fuel consumption but also reflect the impact of fuel-sulphur legislation.
In addition, for SOx, the application of so-called scrubbers to fullfil emission limits especially in SECA areas is taken into account.

For information on the impacts on emission estimates reported for Base Year and 2015, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

With the next annual submission a routine revision of the BSH model used for maritime navigation is scheduled.
