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%.

Total GHG emissions from the ETS sector increased by 9.3% in 2024 compared with the previous year, following six consecutive years of decline. The increase was driven by higher emissions across all groups, particularly in electricity and heat production and in manufacturing industries. Despite the increase, emissions remained among the lowest levels recorded over the observed period. At the EU level, a legally binding target has been adopted to reduce GHG emissions from the ETS sector by 62% by 2030 compared with 2005 levels.

Overall energy efficiency of final energy consumption improved by 30 % between 2005 and 2024. The industrial sector contributed the most to this improvement, followed by households, while the transport sector contributed by far the least. In 2024, energy savings compared with 2005 amounted to 1,724 ktoe, equivalent to 44 % of the final energy consumption of the industry, transport and household sectors.

In 2025, 57,118 m² of total floor area of public sector buildings were renovated within the cohesion policy programs, which was 38% less than in the previous year and the lowest level recorded in the 2018–2025 period. In line with the targets set out in the Long-term strategy for energy renovation of buildings by 2050, the energy renovation of 1,150,000 m² of public sector building floor area was planned for the 2021–2025 period; however, only just over half of this amount, or 578,145 m², was actually renovated.

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.
