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. After the pandemic-related halt, the volume has returned to its previous levels.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 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 2022 road transport contributed 43 % to the total emissions of nitrogen oxides. In the period 1990-2022 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 71 % and 76 %. In the period 2000-2022 emissions of particulate matter decreased by 51 %.

In the period 1992–2023 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.4 kg N/ha per year or by 54%, and the net surplus by 1.2 kg N/ha per year or by 85%. The lower surplus was mainly due to a 43% increase in nitrogen removal by crops and a 6% decrease in nitrogen input per hectare of utilized agricultural area. A lower excess of nitrogen indicates better nitrogen management in agriculture and consequently a reduction in emissions of nitrogen compounds into the environment.

The emission of primary particles, smaller than 10 µm (PM₁₀), particles smaller than 2.5 µm (PM_2.5) and all total suspended particles (TSP) have decreased in the period 2000-2022 in Slovenia by 23 %, 33 % and 8 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

The frequency of agricultural drought in Slovenia has been increasing in recent decades. Since year 2000, natural disaster due to drought was declared seven times in Slovenia, the most severe of which occurred in 2003, 2012, 2013, 2017 and 2022. Drought keeps occurring with increasing intensity and in areas and seasons where there have not been problems in the past. An additional risk for drought damage in agriculture present rapidly developing droughts in summer (so-called "flash droughts"), which occur during heat waves.
