[PR07] Exceedances of air quality objectives due to traffic
State

Key message
Bad

Data on air pollution in some parts of urban areas in Slovenia shown, that they are excessively contaminated with NO2 and PM10. The transport sector is one of the major contributors of these pollutants.
Excessive contamination of PM10 in Slovenian urban areas is one of the most pressing environmental problems. Slovenia has already been referred to the European Court of Justice for its levels of PM10.
