 +===== 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.[(DEICHNIK2022)]
 +
 +__Table 1: Annual fuel consumption, in terajoules__
 +|                    ^  1990  ^  1995  ^  2000  ^  2005  ^  2010  ^  2011  ^  2012  ^  2013  ^  2014  ^  2015  ^  2016  ^  2017  ^  2018  ^  2019  ^  2020  ^  2021  ^

 +^ Heavy fuel oil     |   33,3 |   26,0 |   26,0 |   24,4 |   24,5 |  23,0  |  22,6  |  16,8  |  13,8  |  NO    |  NO    |  NO    |  NO    |  NO    |  NO    |  NO    |
 +| **Ʃ 1.A.4.c iii**  ^    338 ^    266 ^    264 ^    250 ^    251 ^    236 ^    232 ^    231 ^    241 ^    284 ^    298 ^    293 ^    356 ^    322 ^    359 ^    265 ^
 +
 +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 [(DEICHNIK2020)] which mainly relate on values from the EMEP/EEA guidebook 2019 [(EMEPEEA2019)]. 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.

 +
 +===== 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.
