Abstract:There are five steps in the estimation of the dollar value of the health effects of emissions of air pollutants: 1) estimate emissions of harmful pollutants; 2) estimate the change in air quality resulting from the emissions; 3) estimate exposure to the polluted air; 4) estimate the health effects resulting from exposure; and 5) estimate the monetary value of the health effects. This analysis is concerned with the first of these five steps: we estimate emissions of criteria pollutants, toxic air pollutants, and greenhouse gases from alternative transportation modes.
