"Francois and Josef are two friends living in Belgium. When they learn that there is going to be a car-free day, they plan a very a special day of activities that can only be done on a day when the cars are all asleep. Learn about World Car-Free Day and the campaign to stop global warming by reducing the greenhouse gas emissions created by exhaust fumes and fuel consumption."--
