It's pickup time at the Vauban kindergarten here at the edge of the Black Forest, but there's not a single minivan waiting for the kids. Instead, a convoy of helmet-donning moms - bicycle trailers in tow - pedal up to the entrance.
Welcome to Germany's best-known environmentally friendly neighborhood and a successful experiment in green urban living. The Vauban development - 2,000 new homes on a former military base 10 minutes by bike from the heart of Freiburg - has put into practice many ideas that were once dismissed as eco-fantasy but which are now moving to the center of public policy.
With gas prices well above $6 per gallon across much of the continent, Vauban is striking a chord in Western Europe as communities encourage people to be less car-dependent. Just this week, Paris unveiled a new electric tram in a bid to reduce urban pollution and traffic congestion.
"Vauban is clearly an offer for families with kids to live without cars," says Jan Scheurer, an Australian researcher who has studied the Vauban model extensively. "It was meant to counter urban sprawl - an offer for families not to move out to the suburbs and give them the same, if better quality of life. And it is very successful."
There are numerous incentives for Vauban's 4,700 residents to live car-free: Carpoolers get free yearly tramway passes, while parking spots - available only in a garage at the neighborhood's edge - go for 17,500 (US$23,000). Forty percent of residents have bought spaces, many just for the benefit of their visiting guests.
As a result, the car-ownership rate in Vauban is only 150 per 1,000 inhabitants, compared with 430 per 1,000 inhabitants in Freiburg proper.
In contrast, the US average is 640 household vehicles per 1,000 residents. But some cities - such as Davis, Calif., where 17 percent of residents commute by bike - have pioneered a car-free lifestyle that is similar to Vauban's model.
Vauban, which is located in the southwestern part of the country, owes its existence, at least in part, to Freiburg - a university town, like Davis - that has a reputation as Germany's ecological capital.
In the 1970s, the city became the cradle of Germany's powerful antinuclear movement after local activists killed plans for a nuclear power station nearby. The battle brought energy-policy issues closer to the people and increased involvement in local politics. With a quarter of its people voting for the Green Party, Freiburg became a political counterweight in the conservative state of Baden-Wuerttemberg.
At about the same time, Freiburg, a city of 216,000 people, revolutionized travel behavior. It made its medieval center more pedestrian-friendly, laid down a lattice of bike paths, and introduced a flat rate for tramways and buses.
Environmental research also became a backbone of the region's economy, which boasts Germany's largest solar-research center and an international center for renewable energy. Services such as installing solar panels and …
