Emission factors

For further information on the emission factors applied please refer to the superordinte chapter on small stationary combustion.

Table 1: Emission factors for commercial and institutional combustion installations

Fuel [kg/TJ] Fuel [kg/TJ]
Hard Coal 76.2 331.7 2,709 48.4 18.5 17.6 15.7 60,000 16.3
Residual Wood 79.2 6.5 2,285 122.1 84.2 81.6 76.9 430,000 355.3
Light Fuel Oil 43.7 3.3 11.9 2.6 1.0 1.0 1.0 160.7 2.7
Natural Gas 27.2 0.1 11.1 0.36 0.03 0.03 0.03 40 1.6

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.


Recalculations were necessary for the latest reference year (2018) 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 are the result of the revision of PAH emission factors.

For specific information on recalculated emission estimates for Base Year and 2018, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

There is a running Project on new emission factors for small combustion plants using updated data from the chimney sweepers and new measurement data.
