This website provides interested association representatives (environmental associations, consumer protection organisations, citizens’ initiatives), regional authorities and municipalities from all the European member states, as well as interested citizens specific information about the litigation on air quality. You will find current proceedings against member states, completed or ongoing legal cases in connection with violations to the Air Quality Directive, and current developments related to the air pollution control measures. Together with our partner ClientEarth, DUH published a Clean Air Handbook, summarizing basic legal information and background material. The handbook is free for download. It informs private people and NGOs to get capable of acting to realize their right on clean air. The DUH will answer your questions about air quality in your neighbourhood.
