 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.

-PM<sub>10</sub> and PM<sub>2.5</sub> emission factors are calculated as a fraction of TSP. Regarding all solid fuels the share of PM10 is 90 % and the share of PM<sub>2.5</sub> 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 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.

-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.
