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.

The emission productivity in Slovenia decreased in 2024 and amounted to 3,09 EUR₂₀₁₀/kg CO₂ eq. The preliminary estimate for 2025 indicates that emissions productivity has improved, reaching EUR 3.5 EUR₂₀₁₀/kg CO₂ eq. The progress in emission productivity in Slovenia when compared to the European Union (EU), is still relatively slow, thus there is a need to further strengthen the connection between economic development and measures for reducing GHG emissions.

Energy efficiency in industry improved significantly between 2005 and 2024, with a 45% increase in 2024 compared to 2005. The chemical industry, machinery and equipment manufacturing, non-ferrous metals, and paper manufacturing contributed the most to the improvement, while steel production and non-metallic mineral products contributed the least.

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.

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.
