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.

[ZD01] Infant mortality due to respiratory diseases

20.08.2024

The data for Slovenia shows that in the past five years, one infant died due to respiratory diseases, specifically in 2021, representing 11.1% of all infant deaths in that year. Research has indicated that air pollution is associated with higher infant mortality rates due to respiratory diseases. However, this relationship is complex, as it is also influenced by other factors such as the presence of allergens, exposure to cigarette smoke, diet, and lifestyle.

[PO39] Share of population connected to the wastewater treatment systems

11.09.2026

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.

[PO07] CO₂ emissions reduction through measures in the public sector

11.09.2026

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.

[PO28] Share of heat produced in energy efficient district heating systems

11.09.2026

In 2024, 83.1% of all heat in district heating (DH) systems was produced in energy-efficient district heating systems, i.e. systems meeting at least one of the criteria defined in Article 50 of the Energy Efficiency Act (ZURE). Compared with 2023, this share decreased by 4.5 percentage points. The combined share of heat from renewable energy sources and waste heat amounted to 20.5% in 2024, which was 0.7 percentage points lower than in the previous year, but 4.8 percentage points higher than in 2016.

[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.
