Frequency of groundwater drought is increasing in recent decades in alluvial aquifers. 8 out of 10 years with highest intensity of groundwater drought in period 1981-2024 occurred after year 2000. Groundwater droughts with higher intensity is characteristic for winter while milder groundwater droughts mostly occur at autumn. Groundwater drought intensity is also increasing seasonally with time between June and September when groundwater use is pronounced.

In 2022, agriculture accounted for 97.5% of total ammonia emissions. From 1990 to 2023, ammonia emissions in Slovenian agriculture decreased by 31.8% and by 15.6% since 2005. Slovenian agriculture is achieving the overall emissions target set out in the NEC Directive (a gradual reduction of at least 15% by 2030 compared to 2005).

Sustainable models of production and consumption contribute to the prevention of waste generation, for which several legislative measures have been adopted. To monitor their implementation, data on various products placed on the market (e.g. plastic carrier bags) and data on waste (e.g. food waste) are collected.

In the first decade of this century, Slovenia directed most of its investments into the road network, particularly in building the motorway system. Railways were neglected also in terms of investments, making them non-competitive with road transport. After 2011, this trend began to change, although the total investment in transport infrastructure decreased after 2008. Since 2010, the country has allocated a larger share of funds to the modernization and upgrade of the railway network.

In Slovenia and in other European countries the proportion of vehicle fleet that comply with the latest and most stringent emission standards increased sharply in period 2011-2020. Penetration of new technology is highest for the diesel cars.
