The analysis of results of the Energy Efficiency Survey of Slovenia for the public and service sector (REUS JSS 2020) indicates that less than a tenth of organisations from the public sector and less than a fifth of office-based companies from the service sector (e.g. banks, post offices and other administrative and office premises) believe that energy consumption in their business premises is either low or very low.

The rate of defoliation and forest decline in Slovenia was relatively stable until 2020, with a slightly negative trend. After 2020, a deterioration of tree defoliation was observed.

The reporting score under the Core data flow of the European Environment Agency decreased for Slovenia in recent years. In 2019, we reached 90%, which is also the EEA target for the average of all countries. In the following years, we reached around 83%. In 2021, 6 EEA countries achieved 100% reporting, 9 countries achieved more than 90%. The 11 most important data flows, supporting major environmental decisions, were evaluated.

Air pollution is the greatest environmental risk to health and a major cause of disease and premature deaths in Europe. Pollution due to PM_2.5 causes respiratory, cardiovascular, neurological and metabolic diseases. Since 2005, the number of premature deaths due to PM_2.5 pollution has been decreasing in Slovenia and in EU countries. In 2019, there were 1,409 premature deaths due to PM_2.5 pollution in Slovenia, and 307,000 in the European Union.

In the last decades, major emissions of air pollutants from transport decreased. However, road transport remains one of the most significant sources of air pollution. In Slovenia in 2020 road transport contributed 38 % to the total emissions of nitrogen oxides. In the period 1990-2020 emissions of substances that cause acidification and emissions of ozone precursors in transport sector declined by 74 % and 77 %. In the period 2000-2020 emissions of particulate matter decreased by 56 %.
