While the declarative attitude of Slovenian households towards the environment and efficient use of energy is improving, the ratio between environmentally aware and unaware households remains unchanged. This is evident from their environmentally oriented behaviour and actual efficiency in energy use. The results of the Slovenian Energy Efficiency Survey – REUS indicate a great potential for reducing final energy consumption in households through the development of environmentally oriented behaviour and positive habits in energy use.

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.

Research from the European Barometer (EBS) since 2008 has continuously testified to the high awareness of Slovenians about climate changes. Despite fluctuations in perception, for the majority – over two-thirds – climate change represents a very serious problem. Since 2015, we have observed a gradual increase in this awareness, which has surpassed three-quarters of respondents in the latest measurements. According to the most recent data from the REUS 2022 study, more than 80% of households recognize the severity of climate changes, confirming a high level of concern among the population.

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.
