A top administrative court in Germany has ruled that cities have the right to ban diesel motors, in an attempt to improve air quality. The decision decided in favour of upholding bans that were introduced by lower courts in the cities of Stuttgart and Düsseldorf, two of the most polluted cities in Germany.
The court stated that it would be up to each city and municipal authority to apply the ban, but advised that it be imposed gradually and allow for exemptions for certain vehicles such as rubbish collection and those used by emergency services.
