The above-average years 2013 and 2014 were followed by below-average year 2015 and average period 2016 – 2021 of annual runoff. In the year 2022 annual runoff was below-average. In the period 2016 – 2021, the driest years were 2003, 2011, 1983, 2022, 2007 and 2015. The downward trend of river runoff from the territory of Slovenian currently persists.

Slovenia is a net importer of food, as domestic production does not satisfy the total domestic needs (especially for vegetables, fruit, potatoes and pig meat). The long-term trend indicates that the self-sufficiency rate is higher and more stable for animal products (milk, eggs, beef and poultry meat), except for pig meat and honey, where the self-sufficiency rate is noticeably decreasing. In the analysed period, surpluses occurred only in the domestic production of milk, beef, poultry meat, in some years in eggs and honey, and in recent years in the production of grain maize.

The level of air pollution with ozone has exceeded the target value for protecting human health in recent years at some urban background monitoring stations (Koper, Nova Gorica Grčna) and at the higher-altitude monitoring station Otlica. The long-term health protection goals have been exceeded at all monitoring stations. The warning value has also been exceeded in recent years only in the Primorska region and at higher altitudes, such as Otlica.

Concentrations of nitrogen dioxide and total nitrogen oxides in ambient air do not exceed the prescribed limit values. Consequently, they are not harmful for human health and vegetation.

In 2022, 75% of energy supply in Slovenia was available to end-users, marking the highest level observed in the period. This percentage is largely influenced by the efficiency of electricity and heat production. In thermoelectric power plants and combined heat and power plants, almost half of the input energy was lost in 2022. Compared to the EU-27 countries, Slovenia ranked in the lower third. Electricity production from combined heat and power plants accounted for just over 6% of total production in Slovenia in 2021, with this share declining in recent years.
