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.

According to the data for 2024, GHG emissions per unit of electricity produced amounted to 175 gCO₂/kWh. In the period 1992–2024, the intensity of GHG emissions decreased by 60,1%. Compared to the EU-27 average, intensity of GHG emissions in Slovenia in 2024 was 4,6% lower.

The share of renewable energy sources (RES) in the use of fuels in industry amounted to 10,7% in 2024, which was 7.1 percentage points behind the annual indicative target value. The 2024 indicative target was thus not achieved. In order to achieve the target of 30% of RES in the use of fuels in industry in 2030, the share of RES will have to increase by 19.3 percentage points or by about approximately 3.2 percentage points per year.

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.

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.
