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.

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.

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%.

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.
