Environmental indicators in Slovenia

Environmental indicators are based on graphs, maps and assessments and as such present environmental trends in Slovenia. The indicators represent one of the four pillars of our environmental reporting, and are prepared in accordance with the Environmental Protection Act. The Environmental Indicators in Slovenia website enables users to browse among 180 indicators. They are based on numerical data and they indicate the state, characteristics and trends of environmental development in Slovenia. They are prepared using a systematic approach based on data and monitoring, as shown in the information pyramid.

The most of energy in transport is used in cars, followed by trucks, the share of which is growing very fast. Efficiency of energy use with excluded influence of transit transport is improving, but too slow.


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 1998–2019, 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.


Inland bathing water quality in Slovenia is good and comparable with bathing water quality in other European countries.


The quality of bathing water along the Slovenian coast is excellent, which ranks Slovenia at the top among the EU countries.


In Slovenia, most of the consumed food (more than 70 %) is imported, only about a third is of Slovenian origin; before 2004, 40 % of the consumed food was imported. After Slovenia joined the EU, the import and export of food has increased significantly. Exports increased mainly at the expense of unprocessed agricultural products, while imports increased at the expense of processed products. More than half of the imported food (60 %) is imported from neighbouring countries (Austria, Croatia, Italy and Hungary), mainly cereals, fruit, vegetables and sugar.


Slovenia is a net importer of food, as it does not cover its demand for agricultural products (cereals, potatoes, vegetables, fruit, pig meat and honey) with domestic production. The long-term trend shows that the self-sufficiency rate for most animal products (milk, eggs, beef and poultry) is higher and more stable, with the exception of pig meat and honey, where the rate of self-sufficiency is decreasing.
