Table: Emission factors for commercial and institutional combustion installations

Pollutant NOx SOx CO NMVOC TSP PM10 PM2.5 PAH PCDD/F

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 explainig dominant emission trends of selected pollutants.

Annual fluctuations of all fuel types in source catagory 1.A.4 depend on heat demand subject to winter temperatures. Between 1990 and 2011 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.

Recalculations

Recalculations were necessary for the latest reference year (2010) 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 (in 2010) due to newly reported activity data and emissions of heat generation from biogas fired small CHP plants.

For pollutant specific information on qualitative and quantitative impacts on 1990 and 2010 emission estimates see chapter 11. Recalculations.

Planned improvements

It´s planned to avaluate the results of a new study in order to revise all activity data.
There are further plans for calculating a complete time serie for biogas in order to ensure the time consistency. Currently only data for 2010 and 2011 are available.
