Geneva wants ban on old diesel cars
In the wake of last week's ruling by a German court that cities can ban diesel cars to fight air pollution, it has emerged that Geneva has drawn up a plan to tackle the problem including a possible temporary ban on diesel cars when pollution levels are critical.
The Geneva plan, which was drawn up in autumn last year, is modelled on France’s Crit'Air system under which cars are grouped into six categories and colours, depending on the year of their registration, their energy efficiency, and their emission quantity.
