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.

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.

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.

The values ​​of the parameters used to monitor the load of rivers with organic substances have decreased significantly since 1996. The observed decrease in organic load corresponds to the increase in the proportion of the population whose wastewater is treated in municipal and joint wastewater treatment plants. The load of rivers with nutrients varies significantly between river basins. The average nitrate values ​​in all river basins of the Danube river basin are higher than in the Soča and Adriatic river basins and above the values of the natural background.
