-The key source of all conventional fuel data is the national energy balance (AGEB, 2019)[(National energy balance and Satellite balance for renewable energy: http://www.ag-energiebilanzen.de/7-1-Energy-Balance-2000-to-2015.html)]. 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 emission factors for power stations and other boiler combustion for production of steam and hot water, in source category 1.A.2.g.viii, have been taken from the research project "Determination and evaluation of emission factors for combustion systems in Germany for the years 1995, 2000 and 2010" (RENTZ et al., 2002)[(Rentz, O. ; Karl, U. ; Peter, H.: Ermittlung und Evaluierung von Emissionsfaktoren für Feuerungsanlagen in Deutschland für die Jahre 1995, 2000 und 2010: Forschungsbericht 299 43 142; Forschungsvorhaben im Auftrag des Umweltbundesamt; Endbericht; Karlsruhe: Deutsch-Französisches Inst. f.

In 2018 and 2019 SO<sub>2</sub>, NOx, TSP, PM, CO, NH<sub>3</sub> and Hg emission factors were revised for all large combustion plants by using data from the large combustion plant reporting (UBA 2019)[(Umweltbundesamt, 2019: Kristina Juhrich, Rolf Beckers: "Updating the Emission Factors for Large Combustion Plants": https://www.umweltbundesamt.de/publikationen/updating-emission-factors-large-combustion-plants)].

-PM10 and PM2.5 emission factors are calculated as a fraction of TSP. The share of PM10 is 90 % and the share of PM2.5 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 PM10 and PM2.5 fractions are considered as 100 % of TSP. Regarding wood a share of 100% PM10 and 90% PM2.5 is used. For liquid fuels the default share of 100% PM10 and PM2.5 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 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. +==== Total Suspended Matter - TSP, PM10 and Priority Heavy Metals - Hg & Cd ====
