The emission productivity in Slovenia improved in 2021 and amounted to 2,79 EUR₂₀₁₀/kg CO₂ ekv. Despite the progress made in recent years, is, however, the progress in emission productivity in Slovenia when compared to the European Union (EU), still relatively slow, thus there is a need to further strengthen the connection between economic development and measures for reducing GHG emissions.

Slovenia has participated in the European Mobility Week (EMW) initiative from the very beginning. Its implementation has become an important form of promotion and encouragement of sustainable mobility planning in the last decade. Since the beginning of the implementation in 2002 136 Slovenian municipalities have participated in the EMW initiative at least once, and 7 municipalities every year. The number of participating municipalities has increased over the years and has already reached almost half of Slovenian municipalities.

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.

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.
