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

- | PM,,10,, and PM,,2.5,, emission factors are calculated as a fraction of TSP. The share of PM,,10,, is 90 % and the share of PM,,2.5,, is 80 %. This is a simple but also conservative approach, knowing that, in reality, PM emissions depend on fuel, combustion and abatement technologies. PM emission reporting starts in 1995, since no sufficient information about the dust composition of the early 1990th is available. | + | PM<sub>10</ |

- | The graph shows sharp declining SO,,x,, emissions between 1990 and 1995 due to decreasing lignite consumption as well as the implementation of stricter regulations in eastern Germany. In the former GDR lignite industry was of prime importance for the economy. After the reunification lignite briquette production in eastern Germany collapsed. The remaining factories had to install flue gas desulphurisation plants. | + | The graph shows sharp declining SO<sub>x</ |
- | The strong decline of SO,,2,, emissions in 2012 can be explained by the change of some power plants from the industrial to the public sector as a result of the closure of hard coal mines. A further reduction of SO,,2,, emissions | + | The strong decline of SO<sub>2</ |

- | Similar to SO,,x,, emissions, TSP and Priority Heavy Metal emission trends show a high dominance of emissions from lignite combustion. Like already discussed for other pollutant, the main reason for sharp declining emissions in this sector is the complete restructuring of the east German lignite industry. The low standard of dust abatement in eastern Germany in the early 1990s involved high heavy metal emissions too. The closing of briquette factories and the implementation of stricter regulations resulted in a considerably improvement of the air quality especially in the New German Länder. | + | Similar to SO<sub>x</ |
