Short description
In NFR category 1.A.3.a i (i) - Internatinal Civil Aviation: LTO emissions during LTO stage (Landing/Take-off: 0-3,000 feet) are reported. In the following, information on sub-category specific AD, (implied) emission factors and emission estimates are provided.

Methodology
Actitvity Data
Specific jet kerosene consumption during LTO-stage is calculated within TREMOD AV as described in the main chapter on civil aviation.

Emission factors
All country specific emission factors used for emission reporting were basically ascertained within UBA project FKZ 360 16 029 (Knörr, W., Schacht, A., & Gores, S. (2010)) 5) and have since then been compiled, revised and maintained in TREMOD AV 6).
For more information, please see superordinate chapter on civil aviation.

1 estimated via a f-BCs (avgas: 0.15, jet kerosene: 0.48) as provided in 7)
2 EF(PM,,2.5,,) also applied for PM,,10,, and TSP (assumption: > 99% of TSP from diesel oil combustion consists of PM,,2.5,,)
3 also including TSP from lead: EF(TSP) = 1.6 x EF(Pb) - see road transport
For the country-specific emission factors applied for particulate matter, no clear indication is available, whether or not condensables are included.
Discussion of emission trends
NFR 1.A.3.a i (i) - International Civil Aviation - LTO is no key category.
Recalculations
As mentioned in the superordinate chapter on 1.A.3.a, the LTO fuel consumptions applied in TREMOD AV have been adapted to the the EMERP/EEA Guidebook 2019. 8)
Hence, the percentual annual shares of kerosene consumed during L/TO for international flights have been re-estimated…

1990 | 1995 | 2000 | 2005 | 2006 | 2007 | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | |

… and the amounts of kerosene allocated to sub-category 1.A.3.a i (i) were revised accordingly:

In parallel, the majority of country-specific emission factors has been revised within TREMOD AV based on information available from the 2019 EMEP/EEA Guidebook 9) and Eurocontrol's AEM model 10). Here, among others, the EF for SO,,2,, from jet kerosene has been replaced by new and more reliable data showing no sulphur reduction since 1990.
