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.

Foodborne infections remain a significant public health concern in Slovenia and globally. In 2023, the incidence of these infections in Slovenia decreased by 7% compared to 2022, with viral intestinal infections being the most common. Among bacterial pathogens, Campylobacter, Clostridioides difficile, Salmonella, and pathogenic E. coli are predominant. The World Health Organization estimates that at least one in ten people worldwide contracts a foodborne infection each year, representing a substantial burden on public health.

In 2022, drinking water monitoring was carried out for 93.8% of Slovenia's population across 863 supply zones that serve 50 or more people. Large and medium-sized zones, serving more than 500 inhabitants, generally maintain a good water quality. The greatest issues are found in smaller zones (50-500 inhabitants) with a higher percentage of fecally contaminated samples. Chemical contamination was detected in two zones, mainly due to exceeded levels of lead and the pesticide desethyl-atrazine.

In the last twenty years, occurrences of hydrological droughts of surface waters have become more frequent and intense compared to the previous period, and the variability between individual years has also increased. Very dry and very wet years alternate with intermediate periods of hydrologically normal years. The intensity of droughts during the growing season has become more frequent, although, in the last decade, it has been less intense than in the decade before.
