In 2019, over three quarters of households surveyed in Slovenia considered climate change a very serious problem. Between 2008 and 2019, the share of these households in Slovenia decreased by 13 percentage points. There has also been a negative trend in agreeing with statements, such as "Human activity contributes most to climate change" or "Climate action must be taken immediately". According to the surveyed households, the major source of the greenhouse gases in Slovenia are industry and transport.


Based on monitoring data for the period 2006–2008, five Slovenian marine water bodies were classified as being in a poor chemical state. This state was determined by values that exceeded the environmental standard of the quality of tributyltin compounds, which have been monitored at the level of the European Union since 2007. Three marine water bodies have been determined to be in a good or very good ecological state.


For the period 2002–2005, an improvement in the chemical and saprobiological quality of rivers was observed.

Due to changes in legislation, this indicator was replaced in 2006 by the indicator [VD12] Chemical and ecological status of surface Waters.
