Take a look

Transportation and climate change

In Slovenia, conventional vehicle propulsion is strongly predominant

Fossil fuels private cars are dominant mode of transport in Slovenia

Key message

Nitrates pollution burden mainly alluvial aquifers. Despite measures applied to the water bodies, no trend of lowering nitrate concentrations is observed.
