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.

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.

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.

In 2025, the leverage of incentives in the public sector amounted to 32.9 euro cents of subsidy for 1 euro of investment, which was 21 euro cents less than in 2024. The decline was due to the projects supported by the Eco Fund under the calls for co-financing new investments in the construction of highly energy-efficient, nearly zero-energy buildings of general public interest. For these projects, the leverage of incentives was only 13.3 euro cents of subsidy for 1 euro of investment, while they accounted for as much as 73% of the total value of supported investments.

Net greenhouse gas (GHG) emissions in the LULUCF sector amounted to -4.452 kt CO₂ eq in 2024, indicating that the sector was a net sink. Compared with 2005, the size of the net sink was 41% lower, mainly due to the impacts of natural disturbances in forests and increased harvesting levels over the past decade. According to the Slovenian Forest Service, timber harvesting in 2025 decreased by approximately 13% compared to 2024, while the share of sanitary fellings remained high, accounting for around 32% of total recorded harvesting.
