Emissions of total ozone precursors in Slovenia decreased by 62 % in the period 1990 to 2020. Emissions of nitrogen oxides decreased by 66 %, carbon monoxide by 70 %, non-methane volatile organic compounds by 54 % and methane by 25 %. The reason is mainly the introduction of more stringent emission standards for motor vehicles. This measure contributed to a significant reduction in emissions of nitrogen oxides and carbon dioxide from road transport which is the main source of ozone precursors. Emissions of nitrogen oxides and non-methane volatile organic compounds were in 2020 below the prescribed target values, which must not be exceeded from 2010 onwards.
