+ | ===== Methodology ===== | ||
+ | |||
+ | ====Activity Data ==== | ||
+ | |||
+ | Primary fuel delivery data for national fishing is included in NEB lines 6 (' | ||
+ | |||
+ | The actual annual amounts used are therefore calculated within (Deichnik (2020)), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.[(DEICHNIK2020)] | ||
+ | |||

+ | | | **1990** | ||
+ | ^ Diesel oil | ||
+ | ^ Heavy fuel oil | ||
+ | | **Ʃ 1.A.4.c iii** ^ 735 ^ 567 ^ 549 ^ 504 ^ 489 ^ 456 ^ 445 ^ 443 ^ 485 ^ 555 ^ 1.117 ^ 1.208 ^ 2.529 ^ 512 ^ | ||
+ | |||
+ | 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, | ||
+ | |||
+ | ==== 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. | ||

+ | 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. | ||
