Environmental indicators in Slovenia

Environmental indicators are based on graphs, maps and assessments and as such present environmental trends in Slovenia. The indicators represent one of the four pillars of our environmental reporting, and are prepared in accordance with the Environmental Protection Act. The Environmental Indicators in Slovenia website enables users to browse among 180 indicators. They are based on numerical data and they indicate the state, characteristics and trends of environmental development in Slovenia. They are prepared using a systematic approach based on data and monitoring, as shown in the information pyramid.

Among the inhabitants of Slovenia, the opinion about the seriousness of the problem of climate change fluctuates somewhat, but all the surveys of the European Barometer EBS on climate change, which have been carried out since 2008, show that for at least two thirds of the population this represents a very serious problem. The share of households that hold this opinion has been slowly increasing since 2015, when it reached its lowest point, and in the last measurement it once again amounts to more than three quarters of the respondents.


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.


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.


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.


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.
