In 2023, 65% of the population was connected to municipal wastewater treatment systems with secondary or tertiary treatment, which do not produce GHG emissions. Compared to the previous year, the share increased slightly, and compared to 2017, it rose by 3.5 percentage points.

In 2023, the share of RES in transport, after a significant drop in 2022, increased again and amounted to 10%. With this, it was 0.7 percentage points behind the non-binding 2023 target from the National Energy and Climate Plan (NECP).

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.

Total greenhouse gas emissions are projected to remain at similar levels as today until 2030 under projection with existing measures, then decline. Under projection with additional measures emissions will decline faster. By 35% by 2030 and by 88% by 2050. Projections show that with intensive implementation of measures, it is possible to achieve the set targets.
