Germany enjoys an enviably green reputation. Environmentalists in other countries applaud its strict environmental laws, its world-class green technology firms, its phase-out of nuclear power, and its influential Green Party. Germans are proud of these achievements, and environmentalism has become part of the German national identity. InThe Greenest Nation?Frank Uekötter offers an overview of the evolution of German environmentalism since the late nineteenth century. He discusses, among other things, early efforts at nature protection and urban sanitation, the Nazi experience, and civic mobilization in the postwar years. He shows that much of Germany's green reputation rests on accomplishments of the 1980s, and emphasizes the mutually supportive roles of environmental nongovernmental organizations, corporations, and the state. Uekötter looks at environmentalism in terms of civic activism, government policy, and culture and life, eschewing the usual focus on politics, prophets, and NGOs. He also views German environmentalism in an international context, tracing transnational networks of environmental issues and actions and discussing German achievements in relation to global trends. Bringing his discussion up to the present, he shows the influence of the past on today's environmental decisions. As environmentalism is wrestling with the challenges of the twenty-first century, Germany could provide a laboratory for the rest of the world.
