Last updated on 14 Mar 2018 09:27 (cf. Authors)

Short description

In sub-category 1.A.5.b iii - Other, Mobile (including Military) emissions from military navigation are reported.

NFR-Code Name of Category Method AD EF Key Category 1
1.A.5.b iii Other: Military - Mobile Combustion: Waterborne T1, T2 NS, M D, M, CS, T1, T3 see superordinate chapter

Method

Activity Data

Primary fuel data for national military waterborne activities is included in NEB lines 6 ('International Deep-Sea Bunkers') and 64 ('Coastal and Inland Navigation') for IMO and non-IMO ships respectively.

The annual shares used within NFR 1.A.5.b iii are therefore calculated within (BSH, 2017), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.

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.

1 due to lack of better information: similar EF are applied for fossil diesel oil and biodiesel
2 ratio PM2.5 : PM10 : TSP derived from the tier1 default EF as provided in [2]
3 estimated from a BC-fraction of 0.31 as provided in [2], chapter: 1.A.3.d.i, 1.A.3.d.ii, 1.A.4.c.iii Navigation, Table 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

This sub-category is not considered separately in the key category analysis.

Due to the application of very several tier1 emission factors, most emission trends reported for this sub-category only reflect the trend in fuel deliveries.
Therefore, the fuel-consumption dependend trends in emission estimates are only influenced by the annual fuel mix.

Selected main pollutants: NOx

Sulphur dioxide and particulate matter

As fuel sulphur content underlies strict legislation, the trends of these directly related emissions reflect the outcome of ever lower fuel sulphur contents.
