- | **//Why are emissions from aviation gasoline reported using a Tier 1 approach whereas for jet kerosene Tier 2a has been applied?// | + | |
- | + | ||
- | For reporting emissions from the cosumption of jet kerosene, the party uses an annual split factor provided by Eurocontrol to devide the total amount of kerosene used (from Energy Balances & Official oil data for the Federal Republic of Germany) onto national and international civil aviation. For aviation gasoline, such split factor does not exist. - Furthermore, | + | |

- | assumption by party: aviation gasoline = AvGas 100 LL | + | |
- | (AvGas 100 LL is the predominant sort of aviation gasoline in Western Europe)[[footnote]] https:// | + | |
- | lead content of AvGas 100 LL: 0.56 g lead/liter (as tetra ethyl lead)[[footnote]] EMEP/EEA GB 2016: "Thus, general emission factors for the stationary combustion of kerosene and the combustion of gasoline in cars may be applied. The only exception is lead. Lead is added to aviation gasoline to increase the octane number. The lead content is higher than in leaded car gasoline, and the maximum permitted levels in the UK are shown below. A value of 0.6 g of lead per litre of gasoline should be used as the default value if there is an absence of more accurate information. Actual data may be obtained from oil companies." | + | |

- | The applied procedure is similar to the one used for calculating lead emissions from leaded gasoline used in road transport. (There, in contrast to aviation gasoline, the lead content constantly declined resulting in a ban of leaded gasoline in 1997.) | + | |
- | + | ||
- | **//On which basis does the party estimate the reported TSP emissions from aviation gasoline?// | + | |
- | The TSP emissions calculated depend directly on the reported lead emissions: The emission factor for TSP is 1.6 times the emission factor used for lead: EF(TSP) = 1.6 x EF(Pb). | ||
- | The applied procedure is similar to the one used for calculating TSP emissions from leaded gasoline used in road transport. | ||
