Appendix A
Committee Sponsors, Statement of Task, and Schedule

The committee’s work was sponsored by four U.S. Federal agencies: Environmental Protection Agency, National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, and National Science Foundation.

STATEMENT OF TASK

This study will summarize the state of knowledge regarding the international flows of air pollutants into and out of the United States and across its various regions, on continental and intercontinental scales. It will also consider the impact of these flows on the achievement of environmental policy objectives related to air quality or pollutant deposition in the United States and abroad and impacts on regional and global climate change. The pollutants to be considered include ozone and its precursors, fine particles and their precursors, mercury, and persistent organic pollutants. The committee will address the following core questions:

  1. How does international transport of air pollutants (including ozone, aerosols, mercury, and POPs) into the United States on continental and intercontinental scales affect air quality, pollutant deposition, and radiative forcing?

    • With respect to ozone and aerosols, how are exceedances of the National Ambient Air Quality Standards (NAAQS) for ozone and fine particles affected by changes in emissions in other countries?

  • With respect to mercury and POPs, how are pollutant deposition and U.S. population exposure affected by changes in emissions in other countries?

  • What is the level of confidence in these estimates?

  1. How are foreign emissions sources expected to change in the future and how might these changes affect achievement of environmental policy objectives in the United States related to air quality, pollutant deposition, and radiative forcing?

  2. How does international transport of air pollutants out of the United States affect air quality, pollutant deposition, radiative forcing, and the achievement of related environmental policy objectives in other parts of the world?

  3. What additional research, observations, analysis, and information management efforts, are needed to better understand and quantify the impacts and implications of the international transport of air pollutants?

Although the committee is encouraged to provide quantitative information to the extent possible, qualitative analysis and discussions may prove appropriate for some topics, especially where the degree of confidence is uncertain. Local scale air pollution issues within shared international transboundary airsheds (such as El Paso-Juarez and Detroit-Windsor) will not be addressed.

ACTIVITIES AND SCHEDULE

The Committee met five times over the course of 18 months from June 2008 to April 2009. These meetings encompassed discussions of the Statement of Task and its context with the study sponsors and other government stakeholders, reviews of the existing literature, presentations from a variety of scientific experts, and evaluation and synthesis of this information into a final consensus report. This report was submitted for peer review in June 2009 and approved for publication in August 2009.

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.
