Paris bans old diesel vehicles to tackle pollution Paris has banned all diesel vehicles aged 13 years or over from the city centre, the latest move in a campaign to tackle pollution on the city's streets. Diesel vehicles over 18 years old and petrol vehicles over 21 years old are already banned in Paris -- a measure that was extended Monday to a new "low-emissions" belt surrounding the city. Central Paris meanwhile went further by also banning diesel cars, trucks and motorbikes aged 13 years and over -- a move aimed at cleaning up the air in a city that is regularly shrouded in smog.
