The energy efficiency preference index among single-family homeowners is 46 (on a scale of 0 to 100), indicating untapped potential for improvement. The analysis reveals a divided market: approximately a fifth of households are completely passive, living in energy-inefficient homes and not considering renovation. Most of the remaining households are already on the path to greater efficiency, either by actively considering renovation or by having already updated individual elements such as windows, the facade, or the roof.

Emissions of primary particles smaller than 10 µm (PM10), particles smaller than 2.5 µm (PM2.5), and all total suspended particles (TSP) decreased in Slovenia in the period 2000–2023 by 26 %, 36 %, and 11 %, respectively. The main source of particulate matter emissions are households, mainly due to the use of biomass for domestic heating.

In 2023, agriculture accounted for 97.4% of total ammonia emissions. From 1990 to 2024, ammonia emissions in Slovenian agriculture decreased by 31.0% and by 15.7% since 2005. Slovenian agriculture is achieving the overall emissions target set out in the NEC Directive (a gradual reduction of at least 15% by 2030 compared to 2005).

In Slovenia, emissions of persistent organic pollutants (polychlorinated biphenyl, polycyclic aromatic hydrocarbons, hexachlorobenzene, dioxins and furans) decreased between 1990-2023, primarily due to targeted legislation, improved control and use of best available technologies.

Heavy metal emissions in Slovenia significantly decreased between 1990 and 2023. This can be largely attributed to the implementation of the EU legislation, improved surveillance and use of the best available technologies.
