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 share of present invasive species (eg. Robinia pseudacacia, Ailanthus altissima, Buddleja davidii, Erigeron annuus) in the last decade shows an increasing trend. An increase in the share of invasive species is evident along the great lowland rivers Sava, Mura and Drava, as well as along the Kolpa river. In higher areas of Slovenia, particularly in the Alps and the Dinaric region, invasive species are very few or entirely absent. However, a notable increase in their share along the western border of the Dinaric region raises concerns.

Domestic material consumption amounted to almost 28 million tonnes (13,1 million tonnes per capita) in 2020 and was 2,6% lower than in 2019. The amount of biomass utilized decreased by 1,5% compared to 2019, also  the amount of mineral resources exploitation by 1,5%. The amount of used fossil energy  increased by 1,5% compared to 2019. In 2020, the import to Slovenia was 3,3 million tonnes higher than the export from Slovenia.

Neutral

The export of waste from Slovenia has been increasing sharply in recent years; since 2009 (after the peak in 2008), the increase has been more than threefold. In 2018, slightly less than 400 thousand tonnes of waste was exported, mostly to Austria and Hungary. The import of waste has been rather stable. In 2018, around 90 thousand tonnes of waste was imported.

Neutral

Values ​​of parameters used for monitoring the organic loading of rivers have greatly reduced since 1996, however ammonium levels remain much higher than natural background. The observed reduction in organic loading corresponds to an increase in the share of population whose wastewater is treated at wastewater treatment plants. The nutrient loading varies considerably among rivers of the Adriatic and the Danube river basins.

Neutral

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 %.

Bad

Slovenian forests are over-mature, the current ratio of forest development phases is unfavourable, forest regeneration is too slow, or the areas of forests under restoration are too small to significantly change the share of forest development phases and thus ensure sustainable forest development. The role of forests as a carbon sink is at risk.
