To reduce pollution in Paris, the city recently introduced new regulations that ban cars built before 1997 from the city center during workdays. The move is expected to reduce emissions of particulate matter and nitrous oxide, a major public health issue in the city.
The city's car ban, which began on July 1, extends to everything from motorcycles to heavy goods vehicles and is in effect Monday through Friday, from 8 a.m. to 8 p.m. The goal is to remove all older, polluting vehicles used for commuting. People can still drive older cars during the weekend.
