1.A.4.c iii - Agriculture/Forestry/Fishing: National Fishing
Short description
In NFR sub-category 1.A.4.c iii fuel consumption and emissions of Germany's maritime fishing fleet are reported.

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 (2019)), 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 2016 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
Recalculations occur only to the revised activity data reported for 2016 and 2017. Here, due to a revision of the official blending rates, the amounts of biodiesel used in NFR 1.A.4.c iii have been revised for 2016 and 2017.

All emission factors remain unrevised, instead.
For pollutant-specific 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 emission factors were adopted from NFR 1.A.3.d i as a comparable emission source.
Planned improvements
Besides a routine revision of the 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.
