-Annual fluctuations of all fuel types in source category //1.A.4.b.i// depend on heat demand subject to winter temperatures. Between 1990 and 2002 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. In 2010 and 2013 fuel consumption was particularly high due to the cold winter. From 2014 - 2017 fuel demand increased due to lower temperatures during the heating period.+Annual fluctuations of all fuel types in source category //1.A.4.b.i// depend on heat demand subject to winter temperatures.

-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.

 It's known that in spite of the existing legislation, an unknown quantity of waste wood is illegally burnt. However, it's impossible to ascertain the fuel quantity, since the use of waste wood for heating purposes in small combustion plants it's illegal. Therefore all emission factors and emissions refer to the use of untreated wood. It's known that in spite of the existing legislation, an unknown quantity of waste wood is illegally burnt.

-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 2019 due to the implementation of the now finalised National Energy Balance. 
-Further recalculations due to a comprehensive revision of PAH Emission factors.+
  
-<WRAP center round info 100%> +Furthermore, compared to submission 2021, PAH emissions have been recalculated for all small combustion sources due to a revision of emission factors applied.
