Activity Data

Primary fuel deliveries data for national inland navigation is included in line 64 ('Coastal and Inland Navigation') of the National Energy Balances (AGEB, 2014) [1] together with respective data for non-IMO ships and vessels used in 1.A.3.d ii (a) - National maritime transport, 1.A.4.c iii - National fishing, 1.A.5.b iii - Military navigation. (NEB line 64 also inlcudes fuel deliveries to 1.A.3.d i (ii) - International inland navigation, that cannot be seperated at the moment.

The AD applied for national inland navigation therefore represents the remains of primary fuel delivery data from NEB line 64 minus the modelled consumption data estimated for non-IMO ships in 1.A.3.d ii (a), 1.A.4.c iii and 1.A.5.b iii:

Emission factors

For main pollutants and particulate matter, modelled emission factors are available from TREMOD (ifeu, 2014a) [2]. - Here, for SO2 and PM, annual values reflect the impact of fuel-sulphur legislation.

For most other pollutants, tier1 default values from (EMEP/EEA, 2013) [3] 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 [4].

Regarding PCDD/F, the country-specific value for diesel oil from (Rentz et al., 2008) [5] has been applied to heavy fuel oil, too.

Furthermore, regarding HCB and PCBs, as no tier1 default EF are available from (EMEP/EEA, 2013), potential emissions are reported as 'NE' at the moment.

Discussion of emission trends

Sub-sector 1.A.3.d ii (b) is not considered separately within the key category analysis.

Basically, emission trends directly follow the trend in over-all fuel consumption:

For sulphur dioxide, emission trends not only follow the trend in fuel consumption but also reflect the impact of fuel-sulphur legislation.
Here, the extreme decrease of SO2 emissions after 2010 results from a sharp reduction of the allowed sulphur-content of diesel oil used in inland navigation. As a result, the apllied EF dropped from 60.5 kg/TJ (2010) to 0.37 kg /TJ (2011). - Here, the development of the EF reflects the stepwise implementation of ever lower limit values. The inventory compiler is aware that already before the coming into force of a new limit value low-sulphur diesel might have been used. Unfortunately, such specific information on fuel qualities is not available to the party, resulting in the extreme trend in estimated SO2 emissions.

Recalculations

Activity data: Due to the newly implemented separation of fuels used in non-IMO ships in national maritime navigation, the amounts used for national inland navigation have been revised downward significantly.

Emission factors: The country specific EF from TREMOD [2] have been revised as follows for 2012:

In addition, PAH emission factors from (EMEP/EEA, 2013a and b) [3], [4] have been implemented, replacing 'NE' notation keys:

As a result of this revison, the summatory value for PAH 1-4 was revised accordingly:

Planned improvements

Besides the routine revision of the TREMOD model, no specific improvements are planned at the moment.
