Methodology
Activity Data
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.
The actual annual amounts used are therefore calculated within (Deichnik (2022)), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.1)

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.
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 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: 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.
Trend discussion for Key Sources
NFR 1.A.4.c iii - National Fishing is no key source.
Recalculations
With both activity data and emission factors unaltered, no recalculations occur against last year's submission.
For pollutant-specific information on recalculated emission estimates for Base Year and 2020, please see the recalculation tables following chapter 8.1 - Recalculations.
Uncertainties
Uncertainty estimates for emission factors were adopted from NFR 1.A.3.d i as a comparable emission source.
Planned improvements
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.
