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 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.

Due to high lead content in the environment, the Upper Meža Valley area was declared a brownfield site area in 2007 and underwent special remediation measures with the aim of protecting the health of people, especially children. Data shows that the lead exposure of children in the Upper Meža Valley improved rapidly in the early years of implementing the remediation measures, but no further improvement was observed after 2010. A prevalence study of lead levels in children's blood from the Meža Valley in 2018 even showed higher values compared to a study conducted in 2013.

The Slovenian EHVZ database (Hydrography and Water Land Records) contains 67.549 watercourses with total length of 41.071 km. Total area of still waters is 24 km² and river reservoirs 31 km².

For use in water management, water land areas are delineated. Total area of water land in Slovenia is 387 km², which is 1, 9 % of continental area of the Republic of Slovenia. Marine water land area is 214 km².

Soil drought has a key impact on plant development and consequently on various industries (forestry, agriculture, …) . Indicators of the number of drought days and the duration of drought periods in individual years show an increase especially after 1990. Similarly, the analysis of the impact of the climate change up to 2100 shows that soil water deficits will increase in the future. The number and the duration of the droughts will increase.
