THE VALUE OF CLEANER AIR: AN INTEGRATED APPROACH

Policymakers in the legislative and regulatory arenas face increasing public expectations that authorities will both promulgate and implement strict environmental programs. At the same time, the aggregate cost of such programs is rising and is impacting economic sectors previously untouched. In this context, a major study used an integrated interdisciplinary perspective to determine what economic benefits would result from air pollution controls. Specifically, the study developed estimates for the health benefits of reducing ozone and fine particulate matter concentrations in the nation's most polluted region-the South Coast Air Basin centering on Los Angeles. This paper presents the economic methodologies and results of that study. It also discusses how health and atmospheric sciences informed the economic assessment.
