THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating soci- ety of distinguished scholars engaged in scientific and engineering research, dedi- cated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its mem- bers, sharing with the National Academy of Sciences the responsibility for advis- ing the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Insti- tute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sci- ences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal gov- ernment. Functioning in accordance with general policies determined by the Acad- emy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing ser- vices to the government, the public, and the scientific and engineering communi- ties. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www. nationa l-academies.org

Preface I ther the past century, increasing consumption of materials and energy to meet growing industrial and population demands has Be_ strained both society and the ecosystem. For about a decade the world community has been working toward better tracking of material and energy flows through the economy and into the environment. Some nations have begun developing indicators of total material requirements, efficiency of materials use, and the impacts on the environment, while realizing that social and economic impacts must be assessed and inte- grated in making related public policy. Formal economy-wide material flows accounts and analyses began in Austria in the l990s and then in other European countries, and the efforts have been coalescing now into a framework with guidelines at the Euro- pean Union level. lapan has been pursuing similar developments. A1- though not yet establishing formal material flows accounts, the United States has a long history of tracking mineral and energy flows through the U.S. Geological Survey, the Bureau of Mines, and the Energy Information Administration. The U.S. Environmental Protection Agency, the U.S. Geo- logical Survey, the Department of Energy, and the National Science Foun- dation, in sponsoring this study, realized the need to examine the poten- tial benefits of material flows accounting and analyses, directed toward making better public policy related to the interactions among industrial processes, the economy, and the environment. This report examines the current state of material flows accounting, the uses and usefulness of the accounts and analyses, and related issues. Conclusions on these topics are given, along with recommendations X1

The report was prepared based on deliberations and discussions among members of the committee, who shared their expertise freely and dedicated themselves to many hours of report writing and re- vision as well as careful review of a number of report drafts. The commit- tee was completely engaged during the study, and a pleasure to work with throughout. The committee is grateful to a number of experts on material flows and industrial ecology at the U.S. Environmental Protection Agency, the U.S. Geological Survey, the Department of Energy, and the National Sci- ence Foundation, who participated in open information-gathering ses- sions. Gratitude is also expressed to many other professionals from in- dustry, associations, nongovernmental organizations, and other state and federal agencies that participated in the process. For the study, we are indebted to Anthony de Souza, Director, Board on Earth Sciences and Resources, and the outstanding assistance of Tammy L. Dickinson, study director, who guided the committee through the entire process and kept us focused and organized. Finally, a great debt of gratitude is owed to the expert reviewers who helped us achieve a cogent and accurate report. Larry Grayson, Chair
