More and more travelers are heading for cities that promote environmentally friendly transport, renewable energy, and restaurants that serve food from sustainable sources. We take you to Hamburg, Neumarkt, and Freiburg.
Hamburg's "Hafen City" is a residential- and business district that's being built in a former industrial area. The city is growing -- without expanding into the suburbs. Neumarkt, in the Oberpfalz region, has won a national award for its sustainability programs. Freiburg is also well-known for its environmentally friendly urban development. Since the early 1990s, the Vauban district has become the focus of Freiburg's sustainability program.
