In Slovenia, in 2023, 55% of children (0-14 years old) in larger cities were exposed to concentrations of 0-20 µg PM10/m3 and 45% of children (0-14 years) in larger cities were exposed to concentrations of 20-30 µg PM10/m3. In Europe, most children live in an environment where PM10 concentrations are below 26 µg/m3.

Asthma is the most common chronic disease among children and one of the major causes of hospitalization to the age of fifteen. In 2019, in EU countries, the share of people reporting asthma was 5,7 %, and for Slovenia it was 4,8 %.  In the period 2018-2022, the municipality of Kostel stood out in terms of the number of hospitalizations for asthma. Children admitted to the hospital for asthma in 2023 were mostly 5 to 9 years old.

In the period 2002-2023, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics. 

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.

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.
