-The key source of all conventional fuel data is the national energy balance (AGEB, 2021)[(National energy balance and Satellite balance for renewable energy: https://ag-energiebilanzen.de/en/data-and-facts/energy-balance-2000-to-2019/)]. Moreover the use of additional statistical data is necessary in order to disaggregate data. Data source for fuel inputs for electricity generation in industrial power stations are shown in Energy Balance line 12. The difference resulting after deduction of the fuel inputs for refinery power stations, pit power stations, power stations in the hard-coal-mining sector and, for the period until 1999, for the power stations of German Railways (Deutsche Bahn) consists of the activity data for other industrial power stations. These data cannot be further differentiated. Additional data from the Federal Statistical Office are needed for allocation of fuel inputs to heat production in industrial power stations and boiler systems. For both electricity production and heat production, gas turbines, gas and steam systems and gas engines are differentiated. These detailed information is provided by the national statistic 067 (industrial power stations). The definition of industrial and public power plants follows the National statistics.+The key source of all conventional fuel data is the national energy balance [(AGEB2022> AGEB, 2022: National energy balance and Satellite balance for renewable energy:  https://ag-energiebilanzen.de/en/data-and-facts/energy-balance-2000-to-2030/ )].

-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.
 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.

 Like already discussed in source category 1.A.1.c, SO<sub>x</sub> emission trend is very much influenced by emissions from lignite fired plants. The strong decline of lignite use in the East German industry and the installation of flue gas desulfurisation plants in the remaining heat and power stations are the main reasons for decreasing SO<sub>x</sub> emissions. Like already discussed in source category 1.A.1.c, SO<sub>x</sub> emission trend is very much influenced by emissions from lignite fired plants.

-The main driver of TSP and Heavy Metal emission trends is the declining lignite combustion in the East German industry especially in the time period from 1990 to 1994. Besides the noticeable improvement of dust extraction installations on the one hand and optimisation of the combustion process on the other hand resulted in considerably decreasing TSP and Heavy Metal emissions. The emission trend of source category 1.A2.g.viii is mainly affected by the closure of industrial plants in Eastern Germany after the reunification and the resulting decrease in fuel consumption. In recent years the use of biomass gains influence.
