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 2013 [2]. 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 [3], [4].

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

Due to the fundamental revision of the applied approach, both diesel oil activity data and emission factors changed widely. The following tables display the recalculated data.

Activity Data

The following table provides the revised over-all activity data. Here, in contrast to earlier submissions, these data include not only the consumption of diesel oil but also of heavy fuel oil.
Nevertheless, given the very conservative approach used in earlier submissions, the over-all fuel consumption has been corrected downward rather significantly.

Emission Factors: Besides the revision of applied values (see table below), new EF have been implemented, replacing 'NE' notations (B[b]F, I[123cd]P).

Due to the newly implemented tier1 EF for B[b]F, B[k]F and I[1,2,3-c,d]P, the summatory EF applied for PAH 1-4 was revised accordingly:

Emissions: Given the broad revisions and further changes described for AD and EF above, all emissions data has been recalculated but cannot be displayed here in full detail.

Due to the broad changes in the NFR structure, no sector- and pollutant-specific information on the impacts on emission estimates are provided in chapter 8.1 - Recalculations with this submission.

Uncertainties

Uncertainty estimates for activity data
Uncertainty estimates for emission factors were adopted from NFR 1.A.3.d i as an comparable emission source.

Planned improvements

Besides the routine maintenance and further development of the BSH model used for all maritime activities, no source-specific improvements are planned.
