Annual fluctuations of all fuel types in source category //1.A.4// depend on heat demand subject to winter temperatures. From 1990 to the present time, 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.

- | The emission trends for PM,,2.5,,, PM,,10,,, and TSP are also influenced severely by decreasing coal consumption in small combustion plants, particularly in the period from 1990 to 1994. Since 1995 the emission trend hardly changed. Increasing emissions in the last years are caused by the rising wood combustion. | + | The emission trends for PM<sub>2.5</ |

The main driver of the POPs emission trend are coal and fuel-wood. PCDD/F emissions decrease from 1990 to 2003 due to decreasing lignite consumption. The use of firewood and therefore PCDD/F emissions from wood combustion show a constant development. | The main driver of the POPs emission trend are coal and fuel-wood.
