Starting in November, Madrid will bar non-resident vehicles from driving anywhere in the city center. The only cars that will be allowed downtown will be those that belong to locals, zero-emissions delivery vehicles, taxis, and public transit like buses.

Madrid is not the only city getting ready to take the car-free plunge. Urban planners and policy makers around the world have started to brainstorm ways that cities can create more space for pedestrians and lower CO2 emissions from diesel.

Here are 13 cities leading the car-free movement.
