-With regard to determination of activity data from waste incineration and co-combustion of waste in combustion system in source category 1.A.2 Energy Balance and energy statistics show smaller waste quantities than the waste statistics of the Federal Statistical Office (Statistisches Bundesamt, Fachserie 19, Reihe 1) [(Statistisches Bundesamt, Fachserie 19, Reihe 1: Abfallentsorgung - URL: http://www.destatis.de/DE/Themen/Gesellschaft-Umwelt/Umwelt/Abfallwirtschaft/_inhalt.html#sprg238672)].

 The table gives an overview of the implied emission factors. In reality the German inventory compiling process is very complex and includes the use of a considerable number of emission factors, which cannot be published completely in the IIR.  The table gives an overview of the implied emission factors.

-Actually there are different emission factors available for diverse fuel types, various techniques and licensing requirements. However, the implied emission factor may give an impression about the order of magnitude.+Actually there are different emission factors available for diverse fuel types, various techniques and due to permissions. However, the implied emission factor may give an impression about the order of magnitude.
 PM<sub>10</sub> and PM<sub>2.5</sub> emission factors are calculated as a fraction of TSP. The share of PM<sub>10</sub> is 90 % and the share of PM<sub>2.5</sub> is 80 % for solid fuels. This is a simple but also conservative approach, knowing that, in reality, PM emissions depend on fuel, combustion and abatement technologies. In terms of natural gas and biogas PM<sub>10</sub> and PM<sub>2.5</sub> fractions are considered as 100 % of TSP. Regarding wood a share of 100% PM<sub>10</sub> and 90% PM<sub>2.5</sub> is used. For liquid fuels the default share of 100% PM<sub>10</sub> and PM<sub>2.5</sub> is used. In the cases of co-incineration, where liquid fuels are only used for ignition in coal fired plants, the share of coal fired plants is used. PM emission reporting starts in 1995, since no sufficient information about the dust composition of the early 1990s is available. PM<sub>10</sub> and PM<sub>2.5</sub> emission factors are calculated as a fraction of TSP.

 The main driver of TSP and Heavy Metal emission trends is the declining lignite combustion due to the closure of industrial plants in the East German industry especially from 1990 to 1994.  The main driver of TSP and Heavy Metal emission trends is the declining lignite combustion due to the closure of industrial plants in the East German industry especially from 1990 to 1994.
