In the last decades, major emissions of air pollutants from transport decreased. However, road transport remains one of the most significant sources of air pollution. In Slovenia in 2019 road transport contributed 44 % to the total emissions of nitrogen oxides. In the period 1990-2019 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 65 % and 72 %. In the period 2000-2019 emissions of particulate matter decreased by 44 %.
