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.a, 2.D.3.h and 2.D.3.i were treated as one source group. Since 2000, a more detailed data collection enables to follow the development of source group 2.D.3.a, which accounts for about 10 – 12% of total NMVOC emissions from solvent-based products. | + | Until 1999, data of the present source categories 2.D.3.a, 2.D.3.h and 2.D.3.i were treated as one source group.

Only a slight decrease in the overall NMVOC emissions can be observed since 2000. The following four product groups, cause the major emissions in category 2.D.3.a: hair sprays, antifreeze agents for cars, eau de toilette and pharmaceutical products. These four product groups comprise together about 44 – 69% of total emissions. | Only a slight decrease in the overall NMVOC emissions can be observed since 2000.
