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.

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.

By 2021, the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the public sector resulted in a cumulative energy savings of 255 GWh, and the cumulative CO₂ emissions reduction was 63 kt. The values of both indicators thus still lagged behind the 2020 target values, which is largely due to the insufficient intensity of investments in 2016 and 2017. In 2022, according to currently available data, energy savings of 33 GWh were achieved, and the CO₂ emissions reduction was 7.4 kt.
