In this approach, solvent-based products or solvents are allocated to the source category, and then the relevant NMVOC emissions are calculated from those solvent quantities via specific emission factors. Thus, the use of this method is possible with the following valid input figures for each product group: | In this approach, solvent-based products or solvents are allocated to the source category, and then the relevant NMVOC emissions are calculated from those solvent quantities via specific emission factors.

- | Until 1999, data of the present source categories 2.D.3.e and f were treated as one source group. From 1990 to 1993 only a rough expert estimation was carried out, which since 1994 in a first step and since 2000 in a second step could be improved by a more detailed data collection that enables to follow the development of source group 2.D.3.e. | + | Until 1999, data of the present source categories 2.D.3.e and f were treated as one source group.

Only a slight decrease in the overall NMVOC emissions can be observed since 2009, probably related to the financial crisis and a decline in production. | Only a slight decrease in the overall NMVOC emissions can be observed since 2009, probably related to the financial crisis and a decline in production. | ||
