-Generally, the calculation method is based on a Tier 2 approach. This means the use of country-specific data at a more detailed level. Emission factors and activity data are available for different fuel types, different technologies, plant size, etc. The use of plant-specific data for a bottom-up approach is not possible. Emissions from industrial power plants cannot be allocated clearly to source category 1.A.2, since reality does not follow the definition of the Guidebook. In real life an industrial power plant generates electricity and heat for the industry but also electricity for the public network. Therefore the borderline between these two categories is not fixed. The market is not static. Frequent changes in the cooperate structure of industrial enterprises including the separation of the energy supply via spin-off from the parent company lead to frequent changes between sector 1.A.1.a, 1.A.1.c and 1.A.2. Therefore it was necessary to develop a flexible calculation system, based on robust emission factors, which can be used for all sectors.+

-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/ )]. 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.+

-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 (now data on waste management are available from the GENESIS-Online database) - URL: http://www.destatis.de/DE/Themen/Gesellschaft-Umwelt/Umwelt/Abfallwirtschaft/_inhalt.html#sprg238672)].

-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)].

-At the time of compiling the inventory, national energy balance is only available provisionally. Therefore, the finalization of the Energy Balance for 2022 led to recalculations.  In addition, to ensure that consumption of fuels in the official data sources is consistently included in the inventory, reallocation of fuel data between 1A1b, 1A1c and 1A2gviii took place for the years 2003-2022.+At the time of compiling the inventory, national energy balance is only available provisionally.
