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.

Energy consumption in transport has been declining slightly in recent years. This is due to combination of lower domestic vehicle consumption as well as lower sales to foreign vehicles. Most of the energy is used in road transport. Consumption of diesel fuel in road transport is increasing.

Inhabitants of the EU-27, including Slovenia, are only partially aware of the problem of increasing volume of transport and its environmental consequences. Public awareness about the effects of transport on the environment is still at a relatively low level, although differences between European countries are substantial. People's awareness of environmental problems caused by transport does not automatically lead to changing mobility habits and is not always reflected in changed behaviour of the population.

In the last decades, major emissions of air pollutants from transport decreased. However, road transport remains one of the most significant sources of air pollution. In Slovenia in 2020 road transport contributed 38 % to the total emissions of nitrogen oxides. In the period 1990-2020 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 74 % and 77 %. In the period 2000-2020 emissions of particulate matter decreased by 56 %.
