The EU air quality legislation requires the Member States to report on zones designated under the Framework Directive on ambient air quality.
Maps of the air quality zones in the EU are also available here:
part II: Zones Germany
Information on zoning and the concentrations in the zones in comparison to air quality objectives is provided through an annual assessment reporting .
Work in progress
In order to be able to aggregate and use zoning information by GIS system, a new reporting of zones is being developed under the new Directive.
