Primary fuel delivery data for national fishing is included in NEB lines 6 ('International Deep-Sea Bunkers') and 64 ('Coastal and Inland Navigation') for IMO-registered and unregistered ships respectively. (AGEB, 2023) 1)
The actual annual amounts used are therefore calculated within (Deichnik (2023)), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.2)

The strong increase after 2015 cannot be conclusively explained at the moment. However, even if the over-all fuel quantities delivered to the navigation sector would be somehow misallocated between the specific nautical acitivities, there would be no over- or under-estimation of over-all emissions.
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 3) which mainly relate on values from the EMEP/EEA guidebook 2019 4). 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: 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.4.c iii - National Fishing is no key source.
With activity data and emission factors remaining unrevised, no recalculations were carried out compared to the previous submission.
Uncertainty estimates for emission factors were adopted from NFR 1.A.3.d i as a comparable emission source.
Besides a routine revision of the underlying BSH model, further focus will be put on the correct allocation of actvity data to the different navigation activities covered in different NFR sub-sectors.
With respect to the strong increase in activity data from 2015 to 2016: This issue is under discussion with the BSH Hamburg as the agency in charge of the underlying model. However, these activity data are based on ship movement data showing a correspondingly increasing trend. Nonetheless, the model is under steady revision and erroneous calculations and results will be corrected whenever they are determined.
