Appendix 2.4 - POP emissions from mobile combustion sources

For PAH exhaust-emissions, default emission factors from the 2019 version of EMEP Guidebook (EMEP/EEA, 2019) ¹⁾ have been applied. Regarding PCDD/F, a tier1 EF from (Rentz et al., 2008) ²⁾ is used instead.

Table 1: Tier1 default emisison factors applied to road vehicles

¹ values differ from EFs applied for fossil diesel oil to take into account the specific NCV of biodiesel

Here, the tier1 values for PAH exhaust emissions have been derived from the following tier1 default values provided in the July 2017 version of the 2016 EMEP/EEA Guidebook:

Table 3: Tier1 default emisison factors applied to NRMM

¹ values differ from EFs applied for fossil diesel oil to take into account the specific NCV of biodiesel
² no separate values available for 2-stroke-mix including 1:50 lube oil.
³ tier1 values derived from ³⁾

Table 3: Tier1 default emisison factors applied to railway vehicles

¹ tier1 default from ⁴⁾, chapter: 1.A.3.b i-iv - Road transport: exhaust emissions: tier1 value for diesel vehicles
² tier1 default from ⁵⁾, chapter: 1.A.3.c - Railways
³ sum of tier1 default value applied for B[a]P, B[b]F, B[k]F, and I[…]P

As the EMEP/EEA GB 2019 does not provide a tier1 value for PCDD/F, the EF applied here has been derived from a study carried out by Rentz et al. (2008) ⁶⁾ for the German Federal Environment Agency. Furthermore, both HCB and PCBs emissions are stated as not applicable in ⁷⁾, chapter 1.A.3.c Railways, Table 3-1 Tier 1 emission factors for railways.

¹ similar EF for biodiesel applied for all mobile sources; due to lack of better information EF values are derived from conventional diesel oil but taking into account the specific NCV of biodiesel
² sum of tier1 default values applied for B[a]P, B[b]F, B[k]F, and I[1,2,3-c,d]P
³ tier1 defaults from ⁸⁾, Chapter: 1.A.3.d.i, 1.A.3.d.ii, 1.A.4.c.iii Navigation: Tables 3-1 and 3-2
⁴ tier1 defaults from ⁹⁾, Chapter: 1.A.3.c Railways: Diesel, Table 3-1
⁵ tier1 defaults from ¹⁰⁾, Chapter: 1.A.3.b.i, 1.A.3.b.ii, 1.A.3.b.iii, 1.A.3.b.iv - Road transport, Table 3-8: HDV, Diesel

The following table provides the tier1 EF applied for POPs from ships and vessels in both civil and military operation in NFR categories 1.A.3.d i -International Maritime Navigation, 1.A.3.d ii - National Navigation (Shipping), 1.A.4.c iii -Fisheryand 1.A.5.b iii - Other: Military Navigation.

⁶ derived from default for fossil diesel oil, but adapted to specific NCV of heavy fuel oil
⁷ tier1 value derived from ¹⁴⁾

The EMEP/EEA GB 2016 (July 2017) does not provide specific defaults for POP emissions from the combustion of jet kerosene and aviation gasoline, stating that for for aviation gasoline these emissions are not estimated (NE):

Therefore, the inventory compiler decided to apply the tier1 EF for PAHs from gasoline fuel used in non-road mobile machinery here, too. Furthermore, both HCB and PCBs emissions are stated as not applicable in ¹⁵⁾, chapter 1.A.3.a, 1.A.5.b Aviation, Table 3.3 Tier 1 emission factors for NFR 1.A.3.a.ii.(i): Civil aviation (domestic, LTO).

As the Party assumes that POP emissions from the combustion of jet kerosene are unlikely to occur, these emission are reported as not applicable (NA).
