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.

The share of renewable sources in total energy consumption was 18.4% in 2024. It remained unchanged compared to the previous year. The growth of RES is very slow and insufficient to achieve the targets in this area.

Slovenia’s import dependence has been lower in recent years, amounting to 48% in 2023. Further increases in energy efficiency, the use of renewable sources, and the diversification of supply sources are essential. Slovenia is completely import-dependent for liquid fuels and natural gas. With regard to natural gas, Slovenia is import-dependent on two countries, Austria and Algeria. In the past, gas reaching Austria mostly came from Russia, but in recent years the supply structure has become more diversified due to the war and sanctions.
