The number of dirty diesel cars and vans [1] on European roads has reached 51 million, four years after the Volkswagen scandal was exposed, a new report by green NGO Transport & Environment finds. The analysis shows an increase by 18% over the past 12 months and a 74% rise since 2016. Considering that Volkswagen is alleged to have installed defeat devices on more cars than thought, the number of dirty diesels might actually be higher.
