Freiburg, Germany, labels itself as a "Green City" and has won several awards for its innovative environmental programs. The city got its start on the path to going greener about 30 years ago when a proposal surfaced to build a nuclear power plant in the area. For many people who live here, perhaps the most notable environmental initiative is the solid waste program. The city's program fee structure provides incentives for both reducing the quantities of materials generated and for handling materials at home. As impressive as the solid waste programs are, it is in the energy field that Freiburg really shines. Led by solar installations, Freiburg's initiatives cover renewable energy as well as energy conservation in buildings and transportation. Recycling derives value in part due to the energy it saves. For buildings, Freiburg has adopted an energy consumption standard in which new buildings are required to be constructed to use only 60% of the energy as the national code provides.
