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.
