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.

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.
