Are New Vehicle Emissions Standards Effective and Efficient?

Research Seminars: Decarbonization Seminar

Joint Seminar ZEW and MISES

What is a feasible and efficient policy to regulate air pollution from vehicles? Theoretically, optimal policy would apply a Pigouvian tax on emissions. Such a tax is technologically infeasible, and most countries instead rely heavily on exhaust standards for new vehicles that limit air pollution emissions per mile, such as carbon monoxide and nitrogen oxides. The paper presented in this Research Seminar assesses these standards’ effectiveness and efficiency. The authors show that the emissions rate of new vehicles in the US has fallen by more than 99 percent since exhaust standards began in 1967. Used vehicles have had comparable declines. They show that exhaust standards have caused much of this decline. Yet exhaust standards are not cost-effective in part because they give no incentive to scrap old vehicles, which account for a large share of total emissions. To study co­unterfactual policies, the authors develop analytical and quantitative models of the new and used vehicle fleets.
