text: Vauban, Germany has taken extreme measures for an experimental district on the outskirts of Freiburg. Vauban streets are car free for the people who live there. People can own a car but have to pay $40,000 for a space in a garage.70% of families dont own a car; and 57% sold a car to move there. Heidrun Walter said " when i had a car i was always tense , I'm much happier this way''.Vauban has come to be a trend in Europe , United States has started to plan a movement called '' smart planning''. Experts say that ''to reduce greenhouse gas we have to drastically reduce emission from tailpipes''. Passenger cars are responsible for 12% og greenhouse gases in Europe , and up 50% in car-intensive areas in the U.S.A . Vauban has mad suburbs more compact and more accessible to public transportation and less space for parking. In this new approach stores are placed a walk away on the main street , better then mall in a distant highway.
