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.

The above-average runoff years of 2013 and 2014 were followed by a below-average year in 2015 and a period of average annual runoff from 2016 to 2021. In 2022, runoff levels were again below average, while 2023 saw a return to above-average conditions. Based on the annual river balance, 2023 ranks among the wettest years in the history of hydrological measurements. Between 1961 and 2023, the most water-abundant years were 2013, 2014, and 2023. In contrast, the driest years were 1983, 2003, 2007, 2011, 2015, and 2022.

In 2024, 118,700 m2 of total floor area of public sector buildings were renovated within the cohesion policy programs, and in the period 2021–2024, 548,200 m2 or 60% of the value planned in the Long-term strategy for energy renovation of buildings by 2050. Within the OP EKP 1.08 million m2 of total floor area were renovated by the end of 2024, which is at the level of the OP EKP target value. For the energy renovation of buildings owned and occupied by the central government the gap behind the target from OP EKP was significant.

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.

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.

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.

Bad

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.
