The emissions of NMVOC have descreased since 1990 for all sectors with the exception of the energy industries and waste. Emissions from energy industries increased during the nineties due to the increasing use of stationary gas engines, which have much higher emissions of NMVOC than conventional boilers. The total anthropogenic emissions have decreased by 48 % from 1990 to 2014, largely due to the increased use of catalyst cars and reduced emissions from use of solvents.
The solvents industry has been doing its' part. There is no reason to scrutinize them much closer. Below is a 1996 assessment of solvents and the places that were most challenged to contain them.
...A preliminary analysis (click here) estimated total global NMVOC release from solvent use to be about 11 per cent of total NMVOC emissions (Watson, et al., 1991). Based on national GHG emissions inventories, NMVOC emissions from these sources can represent a much larger share of the total NMVOC emissions for some countries.
NMVOC from solvent use represents 31 per cent of the total NMVOC emissions for both Italy and Denmark. (ENEA, 1991, Fenger et al., 1990) The Netherlands estimates solvent use to account for 25 per cent, and both Finland and the United States estimate emissions to be 24 per cent of their total NMVOC emissions (van den Born et al., 1991, Boström et al., 1992, US EPA, 1991). By contrast, emissions from solvent use in Nigeria were only 3 per cent of the total NMVOC (Obioh et al., 1992)....
