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.

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.

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.

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.

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.
