In order to meet Clean Air Act requirements, a company expanding its plant, or opening a new plant, may have to offset the associ- ated increase in pollution by arranging for the reduction of pollution from another source. If methanol is a cleaner fuel than gasoline, the expanding company might find that paying other companies to convert their motor vehicles to use methanol--or adopting a methanol strategy itself--is an attractive way to off- set its pollution. For a methanol offset strategy to be economi- cally feasible, and therefore attractive, methanol must be both a less polluting fuel than gasoline and a more cost effective pollution abatement method than alternative methods. Therefore, to explore the merits of a methanol offset strategy, we addressed three questions: 0 Is an automobile burning methanol less polluting than one burning gasoline? * How much does it cost to convert and operate an automobile using methanol relative to the pollution abatement achieved? * How does the cost of methanol conversion compare with more conventional means of reducing air pollution? In sum, methanol-powered vehicles emit less nitrogen oxides than gasoline-powered vehicles; however, for other regulated (972117)
