On Monday, the city council is to vote on a calendar for a new environmental zone (LEZ). From 01.01.2021, vehicles without a badge will be excluded from traffic and the rules will be strengthened every year so that from 2025 only the newest gasoline vehicles as well as electric and hybrid vehicles will be allowed to drive. For the other municipalities of the Metropolitan area, the diesel phase-out is to be staggered until 2030 and a decree is necessary like in the greater Paris area. Bad news for the clearness of rules!
