From the World Carfree network:

Every September 22, people from around the world get together in the streets, intersections, and neighbourhood blocks to remind the world that we don’t have to accept our car-dominated society.

But we do not want just one day of celebration and then a return to “normal” life. When people get out of their cars, they should stay out of their cars. It is up to us, it is up to our cities, and our governments to help create permanent change to benefit pedestrians, cyclists, and other people who do not drive cars.

Let World Carfree Day be a showcase for just how our cities might look like, feel like, and sound like without cars…365 days a year.

As the climate heats up, World Carfree Day is the perfect time to take the heat off the planet, and put it on city planners and politicians to give priority to cycling, walking and public transport, instead of to the automobile.
