-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.  Since 2000, the share of this source group accounts for about 5-8% of total NMVOC emissions from solvent-based products with slightly increasing numbers  (Figures 1-2). +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.
