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 trend of decreasing energy consumption in households between 2010 and 2022 indicates a positive attitude of the population towards efficient energy use. However, since 2017, a negative trend has been observed, particularly in households' awareness of their own energy consumption and in their consideration of more efficient use. With three-quarters of households in 2022 rating their energy consumption as medium to very high, a significant potential for reducing energy consumption in this sector is suggested.

Final energy consumption in buildings amounted to 1,600 ktoe in 2021 and was lagging behind the indicative annual target from the National Energy and Climate Plan (NECP). Compared to the previous year, it increased by 4%, and compared to 2005, it decreased by 17%. Greenhouse gas (GHG) emissions in buildings amounted to 1,021 kt CO₂ eq. in 2021, thus the indicative annual target from NECP was achieved.
