摘要：	Continued interest in improving air quality in the United States along with renewed interest in the expansion of urban passenger ferry service has created concern about air pollution from these vessels. This study shows, as others have before, that emissions from ferries are significant. However, it also shows that there are no serious technical impediments to the development of passenger ferries with much lower emissions than those currently in service, so that ferry commuting can become an environmentally sound choice. Achieving this outcome will require research and development of new technologies, followed by their widespread use. This study first analyzes air pollution (NOX, HC, PM, CO, SO2, and CO2) emissions from three passenger ferries in the San Francisco Bay Area with existing engines (providing the most accurate emissions estimate currently available). It then applies a number of new engine and emissions control technologies to the same level of service in order to evaluate the potential of these new technologies. / Supplementary Notes: Sponsored by Gas Technology Inst., Des Plaines, IL., Brookhaven National Lab., Upton, NY. and Department of Transportation, Washington, DC. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
