Short description

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

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 (Deichnik, K. (2019)), 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 (Deichnik, K. (2019)) 2) which mainly relate on values from the EMEP/EEA guidebook 2019 3). 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.

NOTE: With respect to the emission factors applied for particulate matter, given the circumstances during test-bench measurements, condensables are most likely included at least partly.footnote During test-bench measurements, temperatures are likely to be significantly higher than under real-world conditions, thus reducing condensation. On the contrary, smaller dillution (higher number of primary particles acting as condensation germs) together with higher pressures increase the likeliness of condensation. So over-all condensables are very likely to occur but different to real-world conditions. footnote

+ 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: NO,,x,,

++ 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.

+ Recalculations

The small changes in the activity data applied result solely from a revised biofuel share for biodiesel in 2017:

Table 4: Revised fuel consumption data 2017, in terajoules

= TOTAL = Diesel Oil = Biodiesel
~ Submission 2020 > 500.2 > 489.3 > 10.9
~ Submission 2019 > 500.6 > 489.3 > 11.3
~ absolute change > -0.40 > 0.00 > -0.40
~ relative change > -0.08% > 0.00% > -3.57%

In contrast, all (annual) country-specific emission factors remain unaltered.

For more pollutant-specific information on recalculated emission estimates for Base Year and 2017, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations].

+ Uncertainties

See superordinate chapter] on NFR 1.A.5.b.

+ Planned improvements

A routine revision of the underlying model is planned for the next annual submission.
