After 2007, when it reached its peak, the quantity of waste generated by manufacturing and service activities started to decrease. In 2009, 5.85 million tonnes of such waste was generated. In recent years, the quantity of recovered and deposited waste has been increasing.


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.


Slovenia has some of the greatest subterranean biodiversity in the world. The aquatic fauna, with its 200 species, is by far the richest, while the terrestrial fauna, with 150 species, is second only to the more southern areas of the Dinaric karst. Five Slovenian cave systems have been listed among the 20 richest cave systems in the world. The Postojna-Planina Cave System, with its 50 aquatic and 35 terrestrial species is by far the most abundant. The Cave Protection Act protects the subterranean environment as a whole.
