======Appendix 2.4 - POP emissions from mobile combustion sources======
=====Road Transport=====
For PAH exhaust-emissions, default emission factors from the 2019 version of EMEP Guidebook (EMEP/EEA, 2019) [(EMEPEEA2019)] have been applied.
Regarding PCDD/F, a tier1 EF from (Rentz et al., 2008) [(RENTZ2008)] is used instead.

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:

1 tier1 default from [(EMEPEEA2019)], chapter: 1.A.3.b i-iv - Road transport: exhaust emissions: tier1 value for diesel vehicles \\
2 tier1 default from [(EMEPEEA2019)], 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) [(RENTZ2008)] for the German Federal Environment Agency.
Furthermore, both **HCB** and **PCBs** emissions are stated as //not applicable// in [(EMEPEEA2019)], chapter 1.A.3.c Railways, Table 3-1 Tier 1 emission factors for railways.

===== Aircraft in 1.A.3.a and 1.A.5.b ii =====
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 [(EMEPEEA2019)], 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).
