[PR08] Emissions of air pollutants from transport
Pressures

Key message
Neutral

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 2018 road transport contributed 47 % to the total emissions of nitrogen oxides. In the period 1990-2018 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 58 % and 68 %. In the period 2000-2018 emissions of particulate matter decreased by 35 %.
