Method

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 (BSH, 2015), where ship movement data (AIS signal) allows for a bottom-up approach providing the needed differentiation.

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 [1] 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.

For heavy metals and PAHs, HCB and PCBs, tier1 defaults from [2] are used directly, whereas for PCDD/F values from a study carried out for UBA are applied. - Here, as the guidebook does not provide source-specific values for PAHs, respective values provided for diesel in railways and heavy duty road vehicles have been applied as a gap-filling proxy.

Regarding PCDD/F, a country-specific value for diesel oil from (Rentz et al., 2008) [2] has been applied to heavy fuel oil, too.

Trend discussion for Key Sources

NFR 1.A.4.c iii - National Fishing is no key source.

Recalculations

As no revisions occured in fuel-deliveries statistics (activity data), the only changes result from a revision of the PM2.5 : PM10 : TSP ratio and the newly implemented EF for Black Carbon.

Here, until submission 2016, a PM2.5 : PM10 : TSP ratio of 1:1:1 was applied based on the assumption, that 100 per cent of particulate-matter emissions are below the PM2.5 range.
This assumption was reppaced by the ratio of the tier1 emission factors provided in [3]. This revised ratio was applied to the country-specific EF for PM10 and TSP from [1]:

Furthermore, as mentioned above, Black Carbon emissions are reported for the first time with this submission based on the relevant BC-fractions provided in the 2016 EMEP/EEA Guidebook:

* estimated from f-BC (diesel fuels: 0.31; HFO: 0.12) as provided in [3]

For information on the impacts on 1990 and 2014 emission estimates, 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

With the next CLRTAP submission, Black Carbon (BC) will be reported for all relevant sources. - Besides this, a routine maintenance and further development of the BSH model is planned.
