text: In Vauban, Germany there is a suburb that doesn't have any cars. People are allowed to own cars but there are only two places to park, which are the two large garages at the edge of the development. Also the owner must pay $40,000 for a space, along with a home. The majority of the residents do not own cars and say they are happier this way. This community is an example that is trending throughout Europe, and is trying to kick start a movement called "smart planning". "Passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe... and up to 50 percent in some car-intensive areas in the United States"(Rosenthal 5). The air is becoming very polluted and there are efforts being made to try and fix the issue.
