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.

[OD03] Hazardous waste

05.01.2023

In the last decade (2012–2021), on average around 135,000 tons of hazardous waste was generated annually in Slovenia. This waste accounted for 1% to 3% of all generated waste in Slovenia. Since they contain substances harmful to the environment and health, they must be collected, recovered or disposed of separately from other waste.

In the last decade (2012–2021) each resident of Slovenia annually discards on average around 3.5 kg of hazardous municipal waste, of which the majority in waste electrical and electronic equipment (63%).

[PO29] The installed capacity of the systems for the production of electricity from RES

11.09.2026

From 2012 to 2024, the installed capacity of the systems for the production of electricity from RES has increased by 78,5%. More than three quarters of that increase, 77,2%, was achieved in the last five years. The indicator is currently on a trajectory of achieving the annual indicative values until 2030 set in the National Energy and Climate Plan from 2024 (NECP 2024).

[PO12] Final energy consumption, GHG emissions and the share of renewables in the buildings

11.09.2026

Final energy consumption in buildings amounted to 1,475 ktoe in 2024 and was 2% above the annual indicative value, which was therefore not achieved. Compared to the previous year, it remained at approximately the same level, and compared to 2005, it decreased by 23%. Greenhouse gas GHG emissions in buildings amounted to 1,100 kt CO₂ eq in 2024, thus the annual indicative value was also not achieved.

[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.
