||Polluted air menaces U.S. cities, threatens the health of millions, and causes an estimated $16 billion in damage to materials and crops each year. The largest single polluter is the automobile, emitting over 90 million tons of pollutants--about 33 percent of the total--into the air in a recent year. Because of the extent to which the automobile intensifies this pollution problem, the General Accounting Office (GAO) reviewed the progress of the Environmental Protection Agency (EPA) in combating auto-caused air pollution and the problems encountered.
||Prepared in cooperation with Environmental Protection Agency, Washington, D.C. Office of Air Programs.
