Net greenhouse gas (GHG) emissions in the land use, land use change, and forestry (LULUCF) sector amounted to -4.291 kt CO₂ eq. in 2023. In this year, net sinks were 1.7% higher compared to the previous year and 40% lower compared to 2005. According to the Slovenian Forest Service, felling in 2024 was 7% higher than in 2023. In 2024, the share of sanitary felling was around 45% of the total annual felling, which means that it has increased slightly again.

Final energy consumption in buildings amounted to 1,477 ktoe in 2023 and was 4% lower than the indicative target value from the National Energy and Climate Plan from 2020 (NECP 2020). Compared to the previous year, it remained at approximately the same level, and compared to 2005, it decreased by 23%. Greenhouse gas (GHG) emissions in buildings amounted to 1,024 kt CO₂ eq. in 2023, thus the indicative target value, which is the same in the NECP 2020 and in its update from 2024 (NECO 2024) was not 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.

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.

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.
