Abstract
Between 40 percent and 67 percent of the U.S. population breathes air that is unhealthful. The single largest source of air pollution is tail pipe emissions, accounting for 40 percent of all air pollution. This paper reports on the impact of a five-year program to reduce carbon monoxide in Denver, Colorado. Awareness, knowledge, attitudes, and intentons were affected positively by the program, but there was limited evidence of behavior change. Mandatory components (woodburning bans and use of oxygenated fuels in cars) produced significant reductions in carbon monoxide, while the voluntary component (reduced driving) produced only marginal change.
