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

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.

Bad

In 2025, the amount of incentives for the implementation of measures related to energy efficiency (EE) and renewable energy sources (RES) in non-ETS industry amounted to EUR 1.7 million. This was 53% higher than in the previous year. This amount only takes into account the incentives of the Eco Fund, as other programmes currently do not allow monitoring of the effects related to climate targets for the co-financed projects in industry.

Neutral

The implicit tax rate on energy in Slovenia amounted to 250 €/toe in 2024, which is 1% higher than in the previous year but still 15% lower than in 2016, when it reached its peak in the 2012–2024 period. Compared to the EU-27, it was 0,7 % above the EU average in 2024, while it was below the European average only in the years 2020–2022 due to temporary crisis-related measures. In addition to the tax policy, the rate is also influenced by changes in the structure of energy consumption and energy efficiency.

Neutral

In 2024, 67% of the population was connected to municipal wastewater treatment systems with secondary or tertiary treatment that cause minimal GHG emissions. Compared to the previous year, the share increased by almost 2 percentage points. Compared to 2017, the share increased by 5.4 percentage points.

Neutral

By 2025, the implementation of energy efficiency (EE) and renewable energy measures (RES) in the public sector resulted in total annual energy savings of 365 GWh, and the total annaul CO2 emissions reduction was 92 kt. Investment activity declined in 2025 due to the transition from one financial perspective to the other. In that year, energy savings amounted to 16.8 GWh and the CO2 emissions reduction was 5.3 kt, which are the lowest levels recorded in the 2018–2025 period. No 2030 targets have been set for this indicator.

Bad

In 2025, the leverage of incentives in the public sector amounted to 32.9 euro cents of subsidy for 1 euro of investment, which was 21 euro cents less than in 2024. The decline was due to the projects supported by the Eco Fund under the calls for co-financing new investments in the construction of highly energy-efficient, nearly zero-energy buildings of general public interest. For these projects, the leverage of incentives was only 13.3 euro cents of subsidy for 1 euro of investment, while they accounted for as much as 73% of the total value of supported investments.
