Although the majority of Slovenian households (69%) still consider climate change a serious problem, the REUS 2025 survey reveals a worrying and consistent negative trend: awareness of the problem's seriousness, the urgency of action, and the role of humans is noticeably decreasing compared to previous years.The share of those who consider the problem "very serious" is the lowest to date. Even more telling is the fact that the share of households who believe the problem is "not serious" has quadrupled since 2022 (from 3% to 12%). Support for the statement that immediate action is necessary has dropped by a significant 18 percentage points since 2015. Likewise, agreement that climate change is primarily caused by human activity has decreased by 17 percentage points.An increasing number of households see industry as the main culprit for emissions (the share increased by 10 percentage points compared to 2015, to 42%), while the perceived responsibility of transport is decreasing, despite it being the second-largest source.In conclusion, while basic awareness is still present, the sense of urgency and personal responsibility is diminishing, and the share of those who deny the problem or shift responsibility to other sectors is growing.
