Methodology

Activity data

Primary fuel delivery data (primary activity data, PAD) for international maritime navigation is included in line 6 - 'International Deep-Sea Bunkers' of the National Energy Balances (NEB) (AGEB, 2020) 1) together with respective data for IMO-registered ships used in national maritime transport (see 1.A.3.d ii (a)), fishing (see NFR 1.A.4.c iii) and military navigation (see NFR 1.A.5.b iii).

The AD applied for international maritime navigation therefore represents the remains of primary fuel delivery data from NEB line 6 minus the modelled consumption data estimated for non-IMO ships in 1.A.3.d ii (a), 1.A.4.c iii and 1.A.5.b iii:

AD1.A.3.d i = PADNEB line 6 - AD1.A.3.d ii (a) - IMO - AD1.A.4.c iii - IMO - AD1.A.5.b iii - IMO

with
* AD1.A.3.d i - tier1 activity data for International maritime navigation
* PADNEB line 6 - primary over-all fuel deliveries data from NEB line 6 - 'International Maritime Bunkers'
* AD1.A.3.d ii (a) - IMO - tier3 activity data for IMO-registered ships involved in national maritime navigation
* AD1.A.4.c iii - IMO - tier3 activity data for IMO-registered ships involved in national fishing
* AD1.A.5.b iii - IMO - tier3 activity data for IMO-registered ships involved in military navigation

Consumption of heavy oil has been increasing since 1984 as a result of high petroleum prices, global increases in transports and increasing maritime use of diesel engines that can run on heavy oil. The emissions fluctuations that occurred in the navigation sector in 1992 and 1996 were caused by trade and oil crises.

Furthermore, after 2014, with ever stricter legislation espacially regarding fuel sulphur content, an ongoing shift from heavy fuel oil to maritime diesel oil can be observed.

Emission factors

For main pollutants and particulate matter, modelled emission factors are available from (Deichnik, K. (2020)) 3).

Here, for sulphur dioxide and particulate matter, annual values are available representing the impact of fuel sulphur legislation. In addition, regarding SO2, the increasing operation of so-called scrubbers in order to fullfil emission limits especially within SECA areas is reflected for heavy fuel oil.

For the country-specific emission factors applied for particulate matter, no clear indication is available, whether or not condensables are included.

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.

NFR 1.A.3.d i is not considered in the key category analysis.

Emission trends for unregulated pollutants (such as NH3, NOx, NMVOC and CO, all HM and POPs) with only slight changes in the annual over-all IEFs applied, follow the trends in fuel consumption and the shares of diesel and heavy fuel oil:

On the other hand, the emission trends for SOx and PM, both depending on the fuel's sulphur content, follow not only the trends in fuel consumption but do also reflect fuel-sulphur legislation:

Recalculations

Resulting from changes in the fuel consumption data computed within 7) for domestic maritime navigation, the activity data for 2018 for international maritime navigation have been reviesed.

In contrast, all country-specific and default emission factors applied remain unrevised compared to last year's submission.

For more information on recalculated emission estimates for Base Year and 2018, please see the pollutant-specific recalculation tables following chapter 8.1 - Recalculations.

Uncertainties

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 Knörr et al. (2009) 9).

Planned improvements

Besides routine maintenance and further development of the BSH model, no improvements are planned.
