The emission productivity in Slovenia improved in 2023 and amounted to 3,18 EUR₂₀₁₀/kg CO₂ ekv. Despite the progress made in recent years, is, however, the progress in emission productivity in Slovenia when compared to the European Union (EU), still relatively slow, thus there is a need to further strengthen the connection between economic development and measures for reducing GHG emissions.

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).

From 2012 to 2023, the installed capacity of the systems for the production of electricity from RES has increased by 78,5%. Almost two-thirds of that increase, 51,2%, was achieved in the last four years. The indicator is currently on a trajectory of achieving the indicative targets until 2030 set in the National Energy and Climate Plan (NECP).

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, 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.
