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.

Bad

The ownership of passenger cars, closely linked to their usage, has been steadily increasing in Slovenia for a long time – it has doubled since the country's independence in 1991. Between 2008 and 2015, car ownership grew more slowly due to the economic recession, but since 2015, the growth has accelerated again. The exceptions were the pandemic years of 2020 and 2021. Slovenia's motorization rate (measured in the number of personal cars per thousand inhabitants) exceeds the EU average and is higher than that of many economically more developed EU countries.

Bad

The number of inhabitants who live in the impact area of major roads and railways in Ljubljana and are exposed to high noise levels did not change significantly between 2012 and 2017, and is not decreasing in accordance with the set objectives.

Neutral

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.

Neutral

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.

Neutral

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.

Neutral

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.
