The Water Framework Directive came into force in December 2000. The aim of the directive is to provide a framework for the protection of inland surface waters, transitional waters, coastal waters and the groundwater. The directive has been implemented at national level in the Water Resources Act (WHG) and in the water laws of the Länder, as well as through the issuing of ordinances by the Länder.

The international organisations (custodian agencies) that are responsible for the respective SDG-indicator publish methodical explanations for the indicator - the so-called global metadata.

Here, national time series that fit the global metadata best as well as their comparability with the global metadata are presented. Please find further methodical and country-specific information in the related national metadata.

This tab provides relevant information on the SDG indicators - such as the political target, the primary responsible organisation (custodian agency) and a link to the global metadata. The global metadata is provided by the United Nations Statistics Division.
