The evaluation of the effects of the 1976 Federal freeze on automotive emission controls presented in this article are based on data from New Jersey. Although regional differences exist in driving patterns, vehicle-age-mileage mix, and physical conditions related to pollution dispersion, New Jersey, because of its serious CO, HC, and NOX air pollution problems, is an excellent proving ground for evaluating automotive emission controls. It might appear that freezing Federal emission standards at the 1976 levels may seriously jeopardize future improvements in New Jersey's and the eastern region's ambient air quality. It turns out, as the analysis confirms, that most of the benefits from the FMVCP (Federal Motor Vehicle Control Program) are yet to be realized. In act, it is shown below that in 1985 there will be a projected 68%, 30%, and 32% reduction in average CO, HC, and NOX emissions/mile respectively, compared to 1976 emission levels. These reductions are the result of the change in vehicle-age vs. travel distribution that will take place. As the percentage of travel by pre-Clean-Air-Act and early Clean-Air-Act cars decreases, the full impact of the FMVCP will become realized. Since the cost in increased energy consumption of implementing the original EPA automotive emission schedule would be high and the benefits not substantial, a policy of freezing the 1976 emission standards is sensible.
