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?400|}}

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. 

===== Recalculations =====

Recalculations were necessary for the time series from 2003 to 2019 due to the change of the activity data source. 

Furthermore, compared to submission 2021, PAH emissions have been recalculated for all small combustion sources due to a revision of emission factors applied.

For **pollutant-specific information on recalculated emission estimates for Base Year and 2019**, please see the recalculation tables following [[general:recalculations:start|chapter 8.1 - Recalculations]].

===== 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.
