In 2016 and 2017, the trend of reducing specific emissions of new vehicles has stopped, and in 2018 and 2019 they have even increased. After a 10% reduction in 2020, the specific emissions of new vehicles remained almost unchanged in 2021, falling short of the target set for that year. In 2022, the specific emissions of new vehicles decreased again, by 6%.

In 2021, for the first time since 2016, the average emissions of all vehicles increased slightly in comparison to the previous year. Target values have not been achieved.

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.

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.

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.

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.
