Over the past six years, Paris has done more than almost any city in the world to take space back from cars. Mayor Anne Hidalgo has opened linear parks in the old highways along the Seine, phased out diesel cars in the city, opened bus lanes, raised parking meter prices, and plowed bike lanes down hundreds of streets. When COVID hit, Paris eliminated cars from the Rue de Rivoli, its major crosstown thoroughfare. Plans are in the works to pedestrianize the Champs-Elysées and plant thousands of trees to green, clean, and cool the city.
