 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.

-Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 38%. The main emissions reductions have been achieved in the years since 1999. This successful reduction has occurred especially as a result of regulatory provisions such as the 31st Ordinance on the execution of the Federal Immissions Control Act (Ordinance on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain facilities – 31. BImSchV) [(31. BImSchV: Ordinance on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain facilities; https://www.gesetze-im-internet.de/bimschv_31/index.html)], the 2nd such ordinance (Ordinance on the limitation of emissions of highly volatile halogenated organic compounds – 2. BImSchV) [(2. BImSchV: Ordinance on the limitation of emissions of highly volatile halogenated organic compounds; https://www.gesetze-im-internet.de/bimschv_2_1990/index.html)] and the TA Luft.+Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 55%.

-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. Since 2000, a more detailed data collection enables to follow the development of source group 2.D.3.a, which accounts for about 10 – 16% of total NMVOC emissions from solvent-based products.
  
 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.

-There are no recalculations. +As the emission data for the 2021 reporting could not be completely revised due to staff constraints and for these reasons the emission data for 2018 had to be updated in last year's reporting, a complete recalculation of the emission data for 2019 and 2020 was carried out for this year's reporting. In doing so, it was also possible to take into account the current changes in the systematics of the national production statistics and the foreign trade statistics.
