text: In Vauban, Germany, citizens have give up their cars and have moved into an experimental upscale community where cars are not highly used. Even though car ownership is allowed, there are only two locations to park the vehichle and would cost $40,000 to buy the parking space. As a result, 70 percent of Vauban's families do not own cars, and 57 percent sold their cars in order to move into the experimental community. Media trainer and mother of two, Heidren Walter says:"When I had a car I was always tense. I'm much happier this way." Germany has already taken a first step in order to help reduce car emissions in the air. David Goldberg, an official of transportation for America states:"All of our development since world was II has been centered on the car, and that will have to change." In Europe, passenger cars are responsible for 12 percent of greenhouse gas emissions while the United States is responsible for up to 50 percent greenhouse gas emissions in some car-intensive areas.
