-That project, along with the linear interpolation for the intermediate years, has also provided the underlying data for the source categories 1.A.1.b, 1.A.1.c and 1.A.2.f i, where the factors include power plants, gas turbines or boilers for production of steam and hot/ warm water. The research project was carried out by the Franco-German Institute for Environmental research (Deutsch-Französisches Institut für Umweltforschung - DFIU) at the University of Karlsruhe and was completed in late 2002. The project's aim was to determine and evaluate representative emission factors for the years 1995, 2000 and 2010 for the main air pollutants produced by combustion plants and gas turbine plants in Germany that are subject to licensing requirements. This process consists primarily of analysing and characterising the relevant emitter structures, and the pertinent emission factors, for the year 1995, and then of updating the data for the years 2000 and 2010. This procedure systematically determines emission factors for the substances SO2NOx, CO, NMVOC, dust, and N2O. The process differentiates between 12 coal fuels, 4 liquid fuels, 7 gaseous fuels and firewood. In addition, the available data relative to emission factors of other substances are also compiled; these other substances include PAH, PCDD/F, As, and Cd for combustion systems subject to licensing requirements. +That project, along with the linear interpolation for the intermediate years, has also provided the underlying data for the source categories 1.A.1.b, 1.A.1.c and 1.A.2.f i, where the factors include power plants, gas turbines or boilers for production of steam and hot/ warm water.

-As part of another research project, completed in February 2007, for updating the National Programme in the framework of directive 2001/81/EC on national emission ceilings for certain atmospheric pollutants ("NEC Directive"), individual emission factors for the components SO2NOx and dust were revised in keeping with recent findings.+As part of another research project, completed in February 2007, for updating the National Programme in the framework of directive 2001/81/EC on national emission ceilings for certain atmospheric pollutants ("NEC Directive"), individual emission factors for the components SO<sub>2</sub>NO<sub>x</sub> and dust were revised in keeping with recent findings.
  
-In 2018 and 2019 SO2NOX, TSP, PM, CO, NH3 and Hg emission factors were revised for all large combustion plants. [(UBA 2019: Kristina Juhrich, Rolf Beckers: "Updating the Emission Factors for Large Combustion Plants": https://www.umweltbundesamt.de/publikationen/updating-emission-factors-large-combustion-plants)]) For the reporting year 2016 a complete data set is available. In former times data were not complete. There was no reporting obligation of co-incineration plants. The large combustion data base was also the data basis of the research project (Fichtner et al. 2011) [(Fichtner et al., 2011: W. Fichtner, U. Karl, R. Hartel, D.

 Heavy metal emission factors are mainly the result of a comprehensive study of PRTR data, which provide information about emissions and the quality (measurement/estimated/calculated data) of large combustion plants. The combination of emission from PRTR and the relevant fuel data from a database called "POSO", which contains additional data of large combustion plants, allows the determination of plant-specific emission factors. Due to the fact, that only some plants do really measure heavy metals, the determined emission factors were used for the whole sector (1.A.1.a). Heavy metal emission factors are mainly the result of a comprehensive study of PRTR data, which provide information about emissions and the quality (measurement/estimated/calculated data) of large combustion plants.

-Regarding natural gas and light fuel oil SO2 emission factors were calculated by using data on the sulfur content. In terms of natural gas sulfur content has been measured during a project. Data on all important regions is available. The sulfur of the odorization is also considered, which is a bit conservativ, since not all plants use natural gas with odorization. Concerning light fuel oil, the limit value is used for emission reporting. It can be assumed that large combustion plants mainly use light fuel oil with a sulfur content of 1000 mg/kg while low-sulfur fuel oil is mainly used in small combustion plants.+Regarding natural gas and light fuel oil SO<sub>2</sub> emission factors were calculated by using data on the sulfur content.

 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. 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. The table gives an overview of the implied emission factors.

-PM10 and PM2.5 emission factors are calculated as a fraction of TSP. Regarding all solid fuels the share of PM10 is 90 % and the share of PM2.5 is 80 %. 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.

-SOx emission trend shows the big dominance of lignite due to high Sulphur content of lignite fuels. However SOx emissions decrease more than lignite consumption does. Before the German Reunification in 1990, lignite fired public power plants in Eastern Germany didn't use flue gas desulphurisation plants. The implementation of stricter regulations in the New German Länder resulted in considerably decreasing emissions. In recent years the development of SO2 emissions is mainly influenced by coal consumption. From 2005 onwards biogas which has a considerable sulphur content is gaining in importance. In 2016 emissions from coal fired plants decreased considerably due to a stricter regulation related to the limit values and the reduction efficiency of desulfurization plants. The emission reduction in 2019 is a result of the decreasing coal consumption.+SO<sub>x</sub> emission trend shows the big dominance of lignite due to high Sulphur content of lignite fuels.

-Nitrogen oxides emissions decreases due to declining lignite consumption in the early 1990s and due to NOx emission reduction measurements in the New German Länder. After 2002 the increasing consumption of natural gas biogas, wood and other biomass in the public sector gain influence and increases NOx emissions. The upward trend was only interrupted by the economic crises in 2009. From 2014 onwards NOx emissions decreases mainly caused by the decreasing hard coal consumption.   +Nitrogen oxides emissions decreases due to declining lignite consumption in the early 1990s and due to NO<sub>x</sub> emission reduction measurements in the New German Länder.

-Similar to SOx emissions, Particulate Matter emissions decreases considerably since 1990 due to stricter regulations in eastern Germany. After 2002 PM10 and PM2.5 emission trends were influenced by the increasing use of biomass for public electricity and heat production. TSP and PM emissions from coal fired plants show a decreasing trend from 2005 onwards due to improvements of abatement systems. The remarkable Emission reduction in 2019 is a result of the deacreasing coal consumption. +Similar to SO<sub>x</sub> emissions, Particulate Matter emissions decreases considerably since 1990 due to stricter regulations in eastern Germany.
