Energy efficiency in industry improved significantly between 2005 and 2023, with a 43% increase in 2023 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.

Over the past decade, Slovenia has significantly improved its Eco-Innovation Index, mainly due to the growth in scientific publications, but it still remains slightly below the EU average, as the number of patents and exports of environmental goods and services has declined. Despite this progress, the gap with the EU stood at 4.7% in 2024.

Index includes 12 indicators from five thematic areas. Slovenia is ranked as an average eco-innovation performer. The target value for Slovenia has not been set.

With the increasing share of electric passenger vehicles, CO₂ emissions decreased in 2022 and 2023, but increased slightly in 2024 compared to the previous year due to the decrease in the share. The gap to the target value is almost 34%.

The average emissions of all passenger vehicles increased in 2022 compared to the previous year. In 2023, the average emissions decreased back to approximately the level of 2021. The target values were not achieved.

In 2023, energy efficient district heating (DH) systems, i.e. systems that meet one of the criteria defined in Article 50 of the Act on Energy Efficiency, produced 87,7% of all heat in DO systems, which is the highest value in the observed period. The total share of heat from renewable energy sources (RES) and waste heat amounted to 21,2% in 2023. It increased by 0.5 percentage points compared to the previous year, and by 5.5 percentage points compared to 2016.

The intensity of GHG emissions from fuels and energy in transport in Slovenia was 4.7% lower than the baseline in 2021, which is 1.3 percentage points below the target reduction. Although the intensity is decreasing, the pace is too slow. The largest contribution to reducing intensity comes from the blending of biofuels. In the EU, the largest reductions were achieved by Sweden and Finland, along with 11 other countries that achieved reductions of 6% or more.
