Editors' Summary: To practice environmental law in the 1990s, it is necessary to be familiar with international trade. Trade concerns affect every aspect of environmental law from agricultural subsidies to the disparate impact of pollution abatement regulation on pricing. The following two Dialogues present an overview of the issues and insight on the relationship between international trade and the environment. The first, by a member of the Trade and Environmental Committees of the U.S. Council for International Business, explains how the historic tension between environment and trade can be alleviated by incorporating environmental concerns into the international trade framework. The second, by counsel to the International Trade Commission, delineates specific measures to ensure that environmental concerns are incorporated into international trade decisions. Together, these Dialogues familiarize environmental lawyers with international trade and argue for unifying environmental improvement with liberal trade.
