Net greenhouse gas (GHG) emissions in the land use, land-use change, and forestry (LULUCF) sector amounted to -3.106 kt CO₂ eq in 2021. In this year, the net emissions were higher or sinks smaller by 1.2% compared to the previous year and by 57% compared to 2005. According to data from the Slovenian Forest Service, felling in 2021 decreased by only 3.6% compared to 2020. In 2021, and for the first time since 2014, the share of sanitary felling was less than a third of the total annual felling.

Greenhouse gas (GHG) emissions due to land-use change generally show a declining trend. In 2021, GHG emissions from deforestation decreased by 0.5% 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 2.8% compared to the previous year. The largest share of emissions (66%) 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.

Data on GHG emissions from forest fires show a downward trend, which is, however, not statistically significant. In the long term, there is a major forest fire in Slovenia about every five years, so GHG emissions are relatively high in these years. The highest GHG emissions due to forest fires since we have been recording data were in 2003.
