-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. The higher fuel consumption in 2014 - 2017 is a result of lower temperatures during the heating period. In 2019 and 2020 the fuel demand increased due to decreasing oil prices. Coal use decreased substantially throughout the years. Since 2021, a decrease in the fuel input is observed, with natural gas being the dominant fuel.+Annual fluctuations of all fuel types in source category //1.A.4.b.i// depend on heat demand subject to winter temperatures.

-At the time of compiling the inventory, national energy balance is only available provisionally. Therefore, the finalization of the energy balance for 2023 led to recalculations. Moreover, for the purpose of improving data quality, national energy balances go under revisions every two years (for the years starting from 2003) through fine-tuning of the computational models, consideration of new statistics or re-allocation of activity data. Due to the revisions on the input data for submission 2026, recalculations took place.+At the time of compiling the inventory, national energy balance is only available provisionally.

 There is an ongoing research project on new emission factors for small combustion plants using updated data from the chimney sweepers and new measurement data. The project is on its last phase and when the results become available, implementation into the emission inventory will be assessed. There is an ongoing research project on new emission factors for small combustion plants using updated data from the chimney sweepers and new measurement data.
