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.

Greenhouse gas (GHG) emissions due to land-use change generally show a declining trend. In 2023, GHG emissions from deforestation decreased by 1.5% compared to the previous year, with more than half, i.e. 62%, of these emissions coming from the establishment of agricultural land. GHG emissions due to land conversion to built-up and related land decreased by 2.7% compared to the previous year. The largest share of emissions (75%) is due to the conversion of agricultural land to built-up and related land.

Most Slovenian forests are still undergoing natural regeneration, which guarantees the stability of future forest stands and adaptation to the changing site conditions caused by climate change. Restoration by planting seedlings and sowing (artificial regeneration) only complements natural regeneration when disturbances occur in the process of the natural regeneration of the forest, e.g. where there is no possibility of natural seeding, with the risk of developing erosion processes on exposed forest areas (e.g.

Slovenian forests are over-mature, the current ratio of forest development phases is unfavourable, forest regeneration is too slow, or the areas of forests under restoration are too small to significantly change the share of forest development phases and thus ensure sustainable forest development. The role of forests as a carbon sink is at risk.

In Slovenia, a major forest fire occurs approximately every five years over the long term, which leads to relatively high greenhouse gas emissions in these years. The highest GHG emissions from forest fires since the data was recorded were in 2022, when more than 3,000 ha of forest burned in the Goriški Kras. With higher temperatures, droughts and more frequent heatwaves, the risk of fire is likely to increase, leading to greater uncertainty and more frequent emission peaks.
