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.

[HR01] Exposure to traffic noise

28.05.2021

The number of inhabitants who live in the impact area of major roads outside urban areas has decreased. In 2017, around 16,000 fewer inhabitants were exposed to high noise levels throughout the day and during the night compared to 2012. In urban areas, the number of inhabitants who are exposed to road traffic noise has not decreased. The number of inhabitants who are exposed to high noise levels throughout the day has remained at the same level as in 2012 and is estimated at 64,000.

[EN31] Efficiency of systems of production, transport and distribution of electricity and heat

11.09.2026

In Slovenia, almost 74% of the energy supply is available to final users. This share is influenced to by far the greatest extent by the efficiency of electricity and heat generation.

In 2024, 48% of the energy input was lost in electricity and heat generation in thermal power plants and combined heat and power plants. Compared with the EU-27 countries, Slovenia ranked in the bottom half.

[PO10] Reducing CO2 emissions and final energy use with measures in the housing sector

11.09.2026

The total annual final energy savings due to the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the residential sector amounted to 1,319 GWh in 2025, and the total annual CO2 emissions reduction was 306 kt. Compared to the previous year, annual energy savings decreased by 39%, while the reduction in CO2 emissions fell by as much as 45%. Lower values were only achieved in the period before 2019.

[PO22] Emissions productivity

11.09.2026

The emission productivity in Slovenia decreased in 2024 and amounted to 3,09 EUR2010/kg CO2 eq. The preliminary estimate for 2025 indicates that emissions productivity has improved, reaching EUR 3.5 EUR2010/kg CO2 eq. The progress in emission productivity in Slovenia when compared to the European Union (EU), is still relatively slow, thus there is a need to further strengthen the connection between economic development and measures for reducing GHG emissions.

[PO37] Energy efficiency in industry

11.09.2026

Energy efficiency in industry improved significantly between 2005 and 2024, with a 45% increase in 2024 compared to 2005. The chemical industry, machinery and equipment manufacturing, non-ferrous metals, and paper manufacturing contributed the most to the improvement, while steel production and non-metallic mineral products contributed the least.

[PO20] GHG emissions due to the leakage of F-gases from devices

11.09.2026

F-gas emissions from leaks from stationary installations decreased in 2025 mainly due to lower use of refilled refrigerants. Despite the reduction distance to the indicative target for reducing emissions from the use of F-gases under the EU F-gases Regulation remained large. Compared to 2015, F-gas emissions from leaks were 23% lower in 2025, while, according to the F-gases Regulation, they should have been lower by 76%.
