Freiburg

Vauban, Germany is a new suburb that is part of the 'smart planning movement'. It is car-free, i.e. the streets are car-free, while car ownership is allowed but restricted to two garages, and the cost unbundled. Only 30% of families own cars.

With more and more energy-efficient homes being built and environmentally conscious industry sited in the city, Freiburg, Germany may be one of the greenest cities in the world.
