The contributors examine how international law is changing under pressure from global environmentalism-and how the United States has used green foreign policy to justify initiatives ranging from foreign aid programs to climate change proposals. They show how environmental issues are moving domestic and international agencies away from their original goals toward greener missions and reveal how energy companies and environmentalists often join forces to thwart competition and restrict sovereignty without much positive impact on the environment. In addition, they explain how increased international environmental regulations raise the risk of international tension, reduce free trade, impair U.S. competitiveness, and undermine the confidence and trust of U.S. citizens in their government. This collection of essays ultimately illustrates how expensive the greening of U.S. foreign policy has become and tells how we can find alternatives to government intervention based on free market environmentalism. If the threats of environmentalism are as real as we are led to believe, they can be better handled by returning to the traditional principles of the free society based upon a rule of law The Greening of U.S. Foreign Policy shows how we can return to that path.
