Government health, safety, and environmental standards have, in the past two decades, often created barriers to international trade. These non-tariff barriers have become the focus of trade disputes, negotiations, and agreements. This book explains the dynamics of conflict and cooperation over consumer and environmental regulation between the European Union and the United States. It explores the most celebrated cases of transatlantic conflicts over regulatory standards—the EU's beef hormone and legtrap bans, and America's fuel economy regulations—as well as the successes of the two partners in coordinating rules for chemical and drug testing, animal inspection, and the reduction of ozone-depleting chemicals.
