Total GHG emissions in the EU-ETS sector recorded an annual decrease for the fourth year in a row, in the last year they decreased by almost 7% and reached the lowest value in the observed period. The decrease is mainly a result of much lower GHG emissions in transformations. At the EU level, a legally binding target of reducing GHG emissions by 62% by 2030 compared to the 2005 level has been adopted for this sector, which is a common target for the EU and is not further differentiated by member state. Slovenia has not set a specific target for this sector.

In 2022, 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 almost 87% 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 almost 21% in 2022. It increased by 2 percentage points compared to the previous year, and by 5 percentage points compared to 2016. It was 1.5 percentage point higher than the 2022 indicative target value, set according to the Renewable energy directive.

In 2022, agriculture accounted for 92.7% of total ammonia emissions. From 1990 to 2022, ammonia emissions in Slovenian agriculture decreased by 26.4% and by 11.0% since 2005. Slovenian agriculture is achieving the overall emissions target set out in the NEC Directive (a gradual reduction of at least 15% by 2030 compared to 2005).

The cumulative final energy savings due to the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the residential sector amounted to 1,980 GWh by 2021, and the cumulative CO₂ emissions reduction was 322 kt. Compared to the previous year, energy savings decreased by 6% and the reduction in CO₂ emissions by 5%. In 2022, according to currently available data, energy savings of 272 GWh were achieved, which is the highest value in the observed 2010-2022 period, and the CO₂ emissions reduction was 60.7 kt.

At the end of 2021, the total floor area of energy-renovated buildings in the public sector amounted to 1.92 million m², and a year later to 2.15 million m². Within OP EKP 906,400 m² of total floor area were renovated by the end of 2022. According to the first estimates, the energy-renovated floor area at the end of 2023 will be at the level of the OP EKP target value, while the target from OP EKP for the energy renovation of buildings owned and occupied by the central government will not be achieved.
