The results of the REUS 2025 survey show that the willingness of Slovenian households to use alternative means of transport is increasing. Despite this, the personal car remains the absolutely dominant form of transport, and its use over shorter distances is even strengthening. The main reason for this is undoubtedly the large gap between users' wishes and the actual quality of public transport. The main reasons for not using public transport remain the same as in the past: poor connections, being too time-consuming, and inadequate schedules.

The indicator “Public Awareness on Energy Efficiency” shows that awareness of energy efficiency is high among Slovenian households, but the motivation for it has been changing significantly. Household decisions on energy efficiency have been increasingly driven by finances in recent years, while the environmental aspect is losing importance as an equivalent factor.

The indicator “Public Attitude towards Energy Consumption” points to a stagnation in the self-assessment of final energy consumption in households. The share of households that estimated their energy consumption as low or very low was increasing between 2010 and 2019, but then the trend reversed, and by 2025 it had decreased by 6 percentage points, returning to a similar level as in 2010. A similar situation is observed with households considering more efficient energy use.

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.
