 The main driver of the POP emission trend are coal and fuelwood. PCDD/F emissions from coal fired furnaces are declining but the effect is retarded by increasing wood consumption. The same influencing variables apply accordingly to the PAH emission trends. The emission trend of HCB shows a high dominance of emissions from wood-burning. Data source for HCB emission factors is the EMEP/Corinair inventory guidebook 2006. Insofar, emission factors are constant from 1990 to 2016. Furthermore, the difference between the EFs for coal and fuelwood is very big. Therefore, the emission trend depends solely on the development of fuelwood consumption. Regarding HCB emissions the inventory is incomplete. This is one of the reasons for the importance of emissions from small combustion plants. In 2010, 2012 and 2013 emissions are particularly high because of the cold winter.  The main driver of the POP emission trend are coal and fuelwood.

 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. Recalculations were necessary for the latest reference year (2018) due to the availability of the National Energy Balance.

-Currently it's planned to measure PAH for wood and coal fired stoves in order to replace summarized PAH emission factors by individual PAH emission factors. Otherwise emissions from small combustion plants are not comparable with emissions from the transport sector. +There is a running Project on new emission factors for small combustion plants using updated data from the chimney sweepers and new measurement data.
-In the case of availability of PCB emission factors according to the WHO TEQ for iron and steel and cement industry it's planned to replace country specific PCB emission factors for small combustion plants by using default values.+
