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 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.

In 2024, the share of RES in transport, after an increase in 2023, dropped again and amounted to 9,2%. With this, it was 1,6 percentage points behind the non-binding 2024 target from the updated National Energy and Climate Plan (NECP 2024).

Specific CO₂ emissions from new passenger cars amounted to 127 g CO₂/km in 2024 and decreased to 117 g CO₂/km in 2025. The increase in the share of electric passenger cars contributed significantly to this reduction. Nevertheless, the target value for the 2025–2029 period, set at 93.6 g CO₂/km, has not yet been achieved.

In 2024, average CO₂ emissions from all passenger cars amounted to 157.5 g CO₂/km and changed only marginally compared with 2023. The target value for 2020, set at 152 g CO₂/km, therefore remained unmet.
