Recent advances in air pollution monitoring and modeling capabilities have made it possible to show that air pollution can be transported long distances and that adverse impacts of emitted pollutants cannot be confined to one country or even one continent. Pollutants from traffic, cooking stoves, and factories emitted half a world away can make the air we inhale today more hazardous for our health. The relative importance of this "imported" pollution is likely to increase, as emissions in developing countries grow, and air quality standards in industrial countries are tightened. Global Sources of Local Pollution examines the impact of the long-range transport of four key air pollutants (ozone, particulate matter, mercury, and persistent organic pollutants) on air quality and pollutant deposition in the United States. It also explores the environmental impacts of U.S. emissions on other parts of the world. The book recommends that the United States work with the international community to develop an integrated system for determining pollution sources and impacts and to design effective response strategies. This book will be useful to international, federal, state, and local policy makers responsible for understanding and managing air pollution and its impacts on human health and well-being.

An updated investigation of alternate pathways for American environmental policymaking made necessary by legislative gridlock. The “golden era” of American environmental lawmaking in the 1960s and 1970s saw twenty-two pieces of major environmental legislation (including the Clean Air Act, the Clean Water Act, and the Endangered Species Act) passed by bipartisan majorities in Congress and signed into law by presidents of both parties. But since then partisanship, the dramatic movement of Republicans to the right, and political brinksmanship have led to legislative gridlock on environmental issues. In this book, Christopher Klyza and David Sousa argue that the longstanding legislative stalemate at the national level has forced environmental policymaking onto other pathways. Klyza and Sousa identify and analyze five alternative policy paths, which they illustrate with case studies from 1990 to the present: “appropriations politics” in Congress; executive authority; the role of the courts; “next-generation” collaborative experiments; and policymaking at the state and local levels. This updated edition features a new chapter discussing environmental policy developments from 2006 to 2012, including intensifying partisanship on the environment, the failure of Congress to pass climate legislation, the ramifications of Massachusetts v. EPA, and other Obama administration executive actions (some of which have reversed Bush administration executive actions). Yet, they argue, despite legislative gridlock, the legacy of 1960s and 1970s policies has created an enduring “green state” rooted in statutes, bureaucratic routines, and public expectations.
