Paris slams on the brakes and sets 30 kph speed limit to reduce pollution
Authorities in the French capital of Paris are forcing drivers to slow down, setting a speed limit on almost all the city's roads, in a bid to reduce pollution and improve road safety. But will it work? There are questions over whether the rule -- which limits drivers to 30 kilometers per hour - will actually reduce pollution. Some critics say it will worsen the city's rush-hour traffic jams and could even increase greenhouse gas emissions. That will depend partly on whether drivers get so fed up with the speed limit that they choose to commute in other ways.
