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.

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.


Most Slovenian forests are still undergoing natural regeneration, which guarantees the stability of future forest stands and adaptation to the changing site conditions caused by climate change. Restoration by planting seedlings and sowing (artificial regeneration) only complements natural regeneration when disturbances occur in the process of the natural regeneration of the forest, e.g. where there is no possibility of natural seeding, with the risk of developing erosion processes on exposed forest areas (e.g.


Greenhouse gas (GHG) emissions due to land-use change generally show a declining trend. GHG emissions from deforestation decreased by 1.2% in 2019 compared to the previous year, with more than half, i.e. 58%, of these emissions coming from the establishment of agricultural land. In 2019, GHG emissions decreased by 5.8% over the previous year due to land conversion to built-up and related land. The largest share of emissions (59%) is due to the conversion of agricultural land to built-up and related land.


Areas of fields and gardens in measures that require fertilization based on rapid soil or plant tests have significantly exceeded the target value set by the 2014–2020 Rural Development Programme.


Net greenhouse gas (GHG) emissions in the land use, land-use change, and forestry (LULUCF) sector were -101 kt CO2 eq in 2019. The LULUCF sector was a net emitter in 2014-2018, meaning that emissions were higher than sinks. Forest felling was the largest contributor to sink reductions in this sector during this period. However, in 2019 it decreased by about 13% compared to the previous year, according to Slovenian Forest Service. The amount of sanitary cut in 2019 was 2,835,623 m3 or 54% of the total felling.


In 2019, the indicator shows a slight decline in the eco-innovation index. Slovenia is slightly below the EU average in eco-innovative activities. The target value for Slovenia has not been set. Throughout the observed period, the indicator reflects the fluctuation of Slovenia's eco-innovation index compared to the EU.
