TSP and PM emission factors are to a large extend based on measurements without condensed compounds, according to CEN-TS 15883, annex I.
PAH measurement data contain the following individual substances: Benzo(a)pyrene, Benzo(k)fluoranthene, Indeno(1,2,3-cd)pyrene, Benzo(b)fluoranthene, Benzo(j)fluoranthene, Benzo(ghi)perylene, Anthracene, Benzo(a)anthracene, Chrysene(+Trihenylene) and Dibenz(a,h)anthracene, as a specific part of US EPA.

Trend Discussion for Key Sources

The following charts give an overview and assistance for explaining dominant emission trends of selected pollutants.

Annual fluctuations of all fuel types in source category 1.A.4 depend on heat demand subject to winter temperatures. Between 1990 and 2014 the fuel use changed considerably from coal & lignite to natural gas. The consumption of light heating oil decreased as well. As the activity data for light heating oil is based on the sold amount, it fluctuates due to fuel prices and changing storage amounts. The increasing fuel amount in 2010 can be explained by the availability of biogas fuel data. The reason for the increase of biogas consumption in 2012 is a methodical change. A revision back to 2003 is planned.

Recalculations

Recalculations were necessary for the latest reference year (2014) due to the availability of the National Energy Balance. Germany has a federal structure which causes a time lack of the National Energy Balance. Therefore recalculations are always necessary.
Further recalculations due to a comprehensive revision of emission factors for all main pollutants and heavy metals.

For pollutant specific information on qualitative and quantitative impacts on 1990 and 2014 emission estimates see chapter 11. Recalculations.

Planned improvements

There are further plans for calculating a complete time series for biogas in order to ensure the time consistency depending on the Revision of the national energy balance. Currently, only data for 2010 to 2014 are available.
