The results of the Energy Efficiency Survey of Slovenia (REUS) 2021 show that 61 % of Slovenian households rarely or never use public transport. Depending on the type of settlements, the largest share of households that use public transport live in Ljubljana and Maribor, as well as in the Obalno-kraška region. A good tenth of those households that use public transport, has used public transport in the recent week, while a fifth of households used public transport in the recent month.


The results of the Energy Efficiency Survey of Slovenia - REUS show that the share of Slovenian households that are ready to start using or increase their use of public transport over the next 12 months remains quite small – a trend has not significantly changed during the 2011-2019 period. The data show that almost a tenth of households are ready, while a quarter of households are considering the option, while more than two thirds are not ready to start using or to increase their use of public transport.


The results of the Slovenian Energy Efficiency Survey (REUS) 2019 show that over three quarters of all households decrease their greenhouse gas emissions by walking short distances, about half of them travel by bike, 1 in 7 uses public transport and 1 in 8  uses car sharing. Seven out of ten households were willing to combine their personal vehicle with other forms of transportation in their daily travel.


Air pollution is the most important environmental risk factor for human health, affecting an average of 400,000 premature deaths in the EU and costing Europeans an average of more than € 166 billion a year. In the case of the cities of Ljubljana and Maribor, external costs amount to almost EUR 271 million annually. Estimation of external costs of air pollution from transport is slightly decreasing.


Plans to improve air quality in Slovenia include a number of measures. It is crucial that the state ensures the financing of measures and thus the implementation of measures, and consequently the improvement of ambient air quality. In 2019, as much as EUR 15.56 million more investments were paid out than in 2014. In the period from 2014 to 2019, most investments were in wood biomass boilers, followed by investments in heat pumps.
