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.

Since 2012, the installed capacity of the systems for the production of electricity from RES has increased by 47.3%. More than half of this increase, 24.7%, was achieved in the last three years. The indicator is currently on a trajectory of achieving the indicative targets until 2030 set in the National Energy and Climate Plan (NECP).

According to data from the Ministry of Infrastructure, a total of 135 self-supply devices were connected in 2016, 720 in 2017, and another 1,302 in 2018. In 2016, 130 solar power plants and 5 hydroelectric power plants were connected with a total nominal power of just under 1.1 MW. In 2017, 718 solar power plants and 2 hydropower plants were connected, and the total nominal power of the connected units was slightly under 6.5 MW. In 2018 there were 1,299 solar power plants connected, 2 hydropower plants, and, for the first time, also 1 wind power plant.

According to the first estimates for 2022, GHG emissions per unit of electricity produced amounted to 208 gCO₂/kWh. In the period 1992–2022, the intensity of GHG emissions decreased by 52.8%. Compared to the EU-27 average, it was in Slovenia in 2022 17.1% lower.
