TSP and PM emission factors are to a large extend based on measurements without condensed compounds, according to CEN-TS 15883, annex I.

===== Trend Discussion for Key Sources =====

The following charts give an overview and assistance for explaining dominant emission trends of selected pollutants.

{{:sector:energy:fuel_combustion:small_combustion:1a4ci_ar.png?600|}}

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 & biogas. 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 =====

For the purpose of improving the data quality of the Emission Inventory, National Energy Balances for the years 2003 to 2021 have gone under revisions through fine-tuning of the computational models, consideration of new statistics or re-allocation of activity data, along with other revision mechanisms. These updates led to re-calculations in fuel uses in different sub-categories and in their corresponding emissions.

===== 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.
