In the first decade of this century, Slovenia focused the majority of its investments in the road network, especially on the construction of the motorway. Investments in railways have been neglected and therefore, uncompetitive with the road transport. After 2011, this trend is changing, although the total volume of investments in transport infrastructure has decreased significantly since 2008. Since 2010, Slovenia has been allocating a larger share of funds to the modernization and upgrading of the railway network.

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.

The value of agricultural output in Slovenia fluctuates in the period 1995–2020, which can be a consequence of fluctuation of changes in prices of agricultural products, changes in the volume of agricultural production or changes in both. In last couple of years, the key factor is the physical volume of production, which fluctuates markedly due to changing natural (weather) conditions. Similarly, the value of agricultural output, calculated per capita, fluctuates in the analyzed period, with long-term downward trend.

Slovenian groundwater bodies most polluted with nitrates are those with intergranular (alluvium) aquifers, particularly in north-eastern Slovenia. Groundwater in karst and fractured aquifers is less burdened with nitrates due to geographical conditions, low population density and less agricultural land. In the period 1998–2020, the average annual levels of nitrates in water bodies in the Sava valley, Ljubljansko barje, Savinja, Drava and Mura basins show a statistically significant downward trend. In other water bodies, nitrate levels are not statistically significant.

Air pollution is the most important environmental risk factor for human health, affecting an average of 400,000 premature deaths in the EU and costing Europeans an average of more than € 166 billion a year. In the case of the cities of Ljubljana and Maribor, external costs amount to almost EUR 271 million annually. Estimation of external costs of air pollution from transport is slightly decreasing.
