Abstract

The brochure documents the significant improvements in the Nation’s air quality that have occurred over the past 20 years and the role of motor vehicles in achieving these improvements. Future motor vehicle emission trends for two cities are then presented, first based on current emission model assumptions and then with the National Low-Emission Vehicle program included. This program is only one of several technological changes being advanced by U.S. Environmental Protection Agency. The analysis shows that technological improvements will likely continue to reduce overall motor vehicle emissions well beyond the 2005 upturn predicted in the current model. Finally, the report documents the declining long-term trend in the national vehicle miles traveled (VMT) growth rate.
