 However, to further distribute and allocate the aggregated fuel deliveries onto the different mobile sources, a variety of models has been developed that are now used for computing the extensive basic data from generally accessible statistics, special surveys, and measurements.  However, to further distribute and allocate the aggregated fuel deliveries onto the different mobile sources, a variety of models has been developed that are now used for computing the extensive basic data from generally accessible statistics, special surveys, and measurements. 
      
-For __road transport (1.A.3.b), railways (1.A.3.c), and inland navigation (1.A.3.d ii)__ specific activity data and country-specific implied emission factors at least for regulated pollutants are calculated within __TREMOD ("Transport Emission Estimation Model"__; IFEU). Here, for 1.A.3.b, highly detailled data on annual mileage together with information on fleet composition and new-registration numbers are applied to to allocate the statistically recorded fuel sales to different vehicle types and classes as well as the individual Euro standards. A precise description of the data sources for emission factors used within TREMOD for road transport is provided by the [[https://www.hbefa.net/e/index.html|"Handbook of Emission Factors for Road Transport"]] (version 4.2, 2022).+For __road transport (1.A.3.b), railways (1.A.3.c), and inland navigation (1.A.3.d ii)__ specific activity data and country-specific implied emission factors at least for regulated pollutants are calculated within __TREMOD ("Transport Emission Estimation Model"__; IFEU).

 For estimating emissions from __civil aviation (1.A.3.a)__, specific fuel consumption data for domestic and international flights further distinguished into landing/take-off (L/TO) and cruise phase as well as corresponding implied emission factors are derived from __TREMOD Aviaton (TREMOD AV)__, a standalone module of TREMOD using flight data from the [[https://www.destatis.de/DE/Home/_inhalt.html|German Statistical Office]] (Statistisches Bundesamt, DESTATIS).  For estimating emissions from __civil aviation (1.A.3.a)__, specific fuel consumption data for domestic and international flights further distinguished into landing/take-off (L/TO) and cruise phase as well as corresponding implied emission factors are derived from __TREMOD Aviaton (TREMOD AV)__, a standalone module of TREMOD using flight data from the [[https://www.destatis.de/DE/Home/_inhalt.html|German Statistical Office]] (Statistisches Bundesamt, DESTATIS).

 Another model (__E.M.M.A. - Emission Modelling for Maritime Activities__) is used for national and international maritime navigation, fishing (1.A.4.c iii) and military navigation (1.A.5.b iii) using ship-specific movement data (AIS) for estimating specific fuel consumptions and implied emission factors for domestic trips.  Another model (__E.M.M.A. - Emission Modelling for Maritime Activities__) is used for national and international maritime navigation, fishing (1.A.4.c iii) and military navigation (1.A.5.b iii) using ship-specific movement data (AIS) for estimating specific fuel consumptions and implied emission factors for domestic trips.

 Finally, for emissions from __offroad vehicles and machinery as used in 1.A.2.g vii, 1.A.4.a ii, b ii and c ii__, specific consumption data and IEF are computed within TREMOD Mobile Machinery (TREMOD MM), yet another standalone module of the aforementioned TREMOD. Finally, for emissions from __offroad vehicles and machinery as used in 1.A.2.g vii, 1.A.4.a ii, b ii and c ii__, specific consumption data and IEF are computed within TREMOD Mobile Machinery (TREMOD MM), yet another standalone module of the aforementioned TREMOD.
