-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) [((bibcite 3))], the 2nd such ordinance (Ordinance on the limitation of emissions of highly volatile halogenated organic compounds – 2.

 As emission factors and solvent contents largely remained robust since 2000, domestic consumption of products caused visible changes in NMVOC emissions. For instance, the amount of used ‘antifreeze agents for cars’ per year primarily depends on the weather situation of the specific year. As antifreeze agents have one of the highest domestic consumption values of the category ‘domestic solvent use’, they significantly influence the final value of emitted NMVOC of this category. The increase in emissions in 2010 can be majorly explained by a long-lasting cold season and the need for antifreeze agents. As emission factors and solvent contents largely remained robust since 2000, domestic consumption of products caused visible changes in NMVOC emissions.

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.
