**Sulphur Dioxide** emissions occur during the production of hard-coal coke. The value of the year 1990 is partly based on the GDR’s emission report, chapter “Produktion” (=production) which has no clear differentiation between mining, transformation and handling of coal. The total emission as reported in the emission report is allocated in the NFR categories 1.B.1 and 2. The split factor is based on estimation of experts. | **Sulphur Dioxide** emissions occur during the production of hard-coal coke.

The apparently steep decline from 2007 to 2008 is the result of a research project in 2010, where new emission factors were determined for coke production for the years 2008. | The apparently steep decline from 2007 to 2008 is the result of a research project in 2010, where new emission factors were determined for coke production for the years 2008. | ||

**Particulate matter** emissions occur during the transformation of lignite and hard coal. The very steep decline of the emissions in the early 1990s is due to the shrinking production of lignite briquettes (almost 90% in the first five years).
