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 2023, EU-27 net GHG emissions decreased by 8.9% compared to 2022 and was 37.3% lower than 1990. In 2023, Slovenian GHG emissions decreased by 4.8% compared to 2022. Emissions from non-ETS sectors were 4.4% lower than in 2022 and by 13.6% % lower than in 2005.

Various measures have been taken that waste is destined for recovery, giving priority to recycling and preparation for reuse. Data on waste generation and management is being collected to monitor their implementation.

In Slovenia, the share of landfilled municipal waste in 2022, based on all generated municipal waste, was 8.8% or slightly more than 90,000 tonnes. Thus the goal of reducing the amount of municipal waste landfilled to 10% or less by weight of all generated municipal waste by 2035 has already been achieved. The waste was landfilled at 9 non-hazardous waste landfills.

Temperature in Slovenia is increasing faster than global average. Increase in the annual average temperature is most evident in the last three decades. Warming of the atmosphere will continue according to the climate change projections. The result of warming is an increase in sea level (due to melting of glaciers and thermal expansion), increase in level of the greenhouse gases in the atmosphere (contributes to warming), and many extreme weather and climate events (like floods, droughts, hail and heavy wind), which will influence the quality of our lives.
