Main driver of the NMVOC emission trend is the decreasing lignite consumption. In the residential sector the emission trend is also affected by the increasing use of firewood with high emission factors which levels off the emission reduction. | Main driver of the NMVOC emission trend is the decreasing lignite consumption.

- | Recalculations were necessary for the latest reference year (2017) due to the availability of the National Energy Balance. Germany has a federal structure which causes a time lack of the National Energy Balance. Therefore recalculations are always necessary. | ||
- | Further recalculations due to a comprehensive revision of biomass data. | ||
