 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.  Annual fluctuations of all fuel types in source category //1.A.4// depend on heat demand subject to winter temperatures.

 ===== Recalculations ===== ===== Recalculations =====
  
-Recalculations were necessary for the latest reference year (2017) 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 biomass from 2003 onwards.+Recalculations were necessary for the time series from 2003 to 2019 due to the change of the activity data source. 
  
-<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.  
-For specific **information on recalculated emission estimates for Base Year and 2018**, please see the pollutant specific recalculation tables following chapter [[General:Recalculations:Start| 8.1 - Recalculations]].+
