Under a landmark ruling by a federal court in Leipzig, German cities can now ban older diesel engine vehicles. The cities of Stuttgart and Dusseldorf are allowed to legally ban older higher polluting diesel cars from zones that are badly affected by air pollution. Environmental group DUH brought the lawsuit after 70 German cities exceeded European Union limits for nitrogen oxides (NOx) in 2017. NOx emissions can cause respiratory disease and difficulty breathing.

Diesel engines produce high levels of nitrogen oxide, and low levels of carbon dioxide. EU air quality standards are not being met in cities across Europe, so that this could set a precedent for Europe, says the BBC.

Of the 15 million diesel cars on German roads only 2.7 million meet the latest Euro-6 standards, according to German automotive watchdog agency. Diesel car market share is dropping- falling to 39% in 2017 from 48% in 2015. The VW diesel emissions scandal in 2015 further eroded public confidence.

The German government already has suggested alternatives such as offering free public transport in cities with poor air quality. The government opposed the ruling because it did not want the car industry to bear the additional cost of retrofitting older vehicles at a time when German carmakers were investing in electric vehicles. 

Yet the trend is clear. Paris, Madrid, Mexico City, Athens have pledged to ban diesel vehicles from the centre of cities by 2025, with Copenhagen doing this in 2019.
