In Slovenia, in 2022, drinking water monitoring (quality monitoring) was conducted for 93.8% of the population at the point of use (user's tap) across drinking water supply systems or within 863 supply zones that served 50 or more inhabitants. This also included 26 smaller supply areas that provided water to public facilities and facilities involved in the production and distribution of foodstuffs.

The data for Slovenia shows that in the past five years, one infant died due to respiratory diseases, specifically in 2021, representing 11.1% of all infant deaths in that year. Research has indicated that air pollution is associated with higher infant mortality rates due to respiratory diseases. However, this relationship is complex, as it is also influenced by other factors such as the presence of allergens, exposure to cigarette smoke, diet, and lifestyle.

Values ​​of parameters used for monitoring the organic loading of rivers have greatly reduced since 1996, however ammonium levels remain much higher than natural background. The observed reduction in organic loading corresponds to an increase in the share of population whose wastewater is treated at wastewater treatment plants. The nutrient loading varies considerably among rivers of the Adriatic and the Danube river basins.

The year 2022 was exceptional for electricity production in Slovenia, as difficulties with coal supplies led to the lowest production from solid fuels since 1992, and drought also reduced production from renewable energy sources. This resulted in a record share of nuclear energy in electricity production (42%) and very low total production (13.4 TWh), the lowest since 1999. The share of domestic electricity production was 71%, below the target set in the National Energy and Climate Plan, and the annual production was 40% lower than the gross consumption.

Although electricity and heat generation increased by 30% between 1990 and 2021, CO2 emissions decreased by 31.5%, mainly due to the increase in generation efficiency, as well as to the increase in RES and nuclear generation. SO2 emissions decreased by almost 99%, mainly due to the installation of desulphurisation, the increase in generation efficiency and share of RES and nuclear generation.
