AAA Says Smog Not Just Cars

WASHINGTON -- The American Automobile Association says cars and small trucks account for less than one-third of smog-causing air pollution in major U.S. cities.

The AAA, a leading advocacy group for motorists, said Tuesday a study of air pollution in 24 major cities shows that more than 70 percent of the chemicals that cause smog come from factories, utility smokestacks, refineries and other stationary sources.

Tougher air pollution controls are expected to be imposed by states and local communities in the next few years to comply with new federal air quality standards.

AAA vice president James Kolstad said the air pollution study conducted for AAA by a private consultant shows automobiles "are falsely portrayed as major causes of smog in our cities.'' He maintained cars should not be targeted for further pollution controls.
