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.

Did you know?

Good

In 2022, 75% of energy supply in Slovenia was available to end-users, marking the highest level observed in the period. This percentage is largely influenced by the efficiency of electricity and heat production. In thermoelectric power plants and combined heat and power plants, almost half of the input energy was lost in 2022. Compared to the EU-27 countries, Slovenia ranked in the lower third. Electricity production from combined heat and power plants accounted for just over 6% of total production in Slovenia in 2021, with this share declining in recent years.

Good

In the period 1992–2023 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.4 kg N/ha per year or by 54%, and the net surplus by 1.2 kg N/ha per year or by 85%. The lower surplus was mainly due to a 43% increase in nitrogen removal by crops and a 6% decrease in nitrogen input per hectare of utilized agricultural area. A lower excess of nitrogen indicates better nitrogen management in agriculture and consequently a reduction in emissions of nitrogen compounds into the environment.

Neutral
Air

The emission of primary particles, smaller than 10 µm (PM10), particles smaller than 2.5 µm (PM2.5) and all total suspended particles (TSP) have decreased in the period 2000-2022 in Slovenia by 23 %, 33 % and 8 %. The main source of emissions of particulate matter are households, mainly due to use of biomass for domestic heating.

Bad

The frequency of agricultural drought in Slovenia has been increasing in recent decades. Since year 2000, natural disaster due to drought was declared seven times in Slovenia, the most severe of which occurred in 2003, 2012, 2013, 2017 and 2022. Drought keeps occurring with increasing intensity and in areas and seasons where there have not been problems in the past. An additional risk for drought damage in agriculture present rapidly developing droughts in summer (so-called "flash droughts"), which occur during heat waves.

Neutral

2024 was the second consecutive year with above-average water abundance, with no surface water drought observed in any season. However, over the past twenty years, hydrological droughts of surface waters have become both more frequent and more intense compared to previous periods, with greater variability between individual years. Very dry and very wet years now alternate with periods of hydrologically normal conditions. The drought intensity during the growing season has become more frequent, though it has been less severe in the past decade than in the previous one.

Good

More than half of households in Slovenia have already used financial incentives for energy efficiency and renewable energy sources or are actively considering it. The index of household preferece for financial incentives offered by the Eco Fund increased positively by 4 index points from 2019 to 2022, when it was 52 on a scale from 0 to 100. Preference for these financial incentives varies between regions. On the one hand, knowledge and interest in the Eco Fund services is decreasing, while on the other hand, the share of households that have opted for these services again is increasing.
