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. The most polluted areas with inorganic pollutants were Jesenice, Idrija, the Celje Basin and the Upper Mežica Valley.

In 2021 the Water Rights for special use of water were issued in 8385 acts (water permits, concessions), with additional more than 10.000 cases of minor spatial water uses with neglectable influence on state of water, were in the process of evidencing in the Water Book.

Road goods transport has been growing sharply since Slovenia joined the EU, as the volume of tonne-kilometres of the Slovenian transport carriers increased by more than 2,5 times in the period 2004-2019. The growth of freight transport and transit in Slovenia has been constant in road, rail and maritime transport since independence, despite intermediate economic problems in the EU during the recession 2008-2014. The exception is air freight transport, which has stagnated for years after a sharp decline in 2008.

In Slovenia and in other European countries the proportion of vehicle fleet that comply with the latest and most stringent emission standards increased sharply in period 2011-2020. Penetration of new technology is highest for the diesel cars.

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.
