On September 27,2015, Paris is going car-free (sort of) for one day. Une Journée Sans Voitures , sponsored by the Paris municipal government, will temporarily pedestrianize streets and boulevards in the 1st through 7th and the 10th,11th and 16th arrondissements. The day without cars coincides with the UN COP21 climate conference in Paris.

Tourists will no doubt be delighted to wander the exhaust-free streets—Parisian motorists not so much.Everyone can learn more about the project at this website.
