Systematic research on soil pollution shows that soils in Slovenia, with some exceptions, are not heavily polluted. In 42% of top soil samples taken in the period from 1999 to 2019, no exceedances of the limit values of dangerous substances into the soil were detected. In 56% of the samples the limit values of inorganic pollutants were exceeded and in 5% the limit values of organic pollutants.

Greenhouse gas (GHG) emissions from transport in Slovenia almost tripled between 1986 and 2019. In the EU, GHG emissions from transport also exceed economic growth on average, but significantly less than in Slovenia; in the period 1990-2019, they increased by 23.6% in the EU-28. The main source of GHG is mostly road transport, which contributes as much as 99% of all GHG emissions from transport.
