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.

In 2024, the energy reduction in the energy efficiency obligation scheme (EEOS) and alternative measure, t. i. Eco Fund programs, amounted to 671 GWh. The savings were more than a half lower than the previous year, mainly due to the fact that the EEOS obligated parties covered their obligations to a large extent with surpluses of savings from previous years. The target value for 2024 was nevertheless exceeded by 38% – because of the transfer of the part of the surplus savings from 2023 within the EEOS the energy savings amounted to 1,028 GWh.

One of the main reasons of mortality due to respiratory diseases is in Slovenia chronic pulmonary disease (COPD). The highest mortality rate due to respiratory diseases in Slovenia is in Podravska and Pomurska region and the lowest in Central-Slovenian region (2022–2024). Mortality due to respiratory diseases is decreasing; in the period 2017 to 2021 it decreased from 62/100.000 inhabitants to 43/100.000 inhabitants in the year 2024. This can be attributed to the “harvesting effect” of COVID 19.

Nutrient over-enrichment remains the key environmental challenge for lakes and reservoirs in Slovenia. For the assessment period 2014–2019, only 4 of the 11 lake water bodies achieved good or high ecological status. Recent annual data indicate no signs of improvement, and in some lakes total phosphorus concentrations are even rising. The main pressures are linked to human activities, especially inappropriate discharge of municipal wastewater, intensive agriculture in the catchments, and fisheries.
