The substantial reductions in motor vehicle emissions that have occurred between the later 1960s and now have been accompanied by continuous increases in vehicle emission control costs. Past estimates of vehicle emission control costs have been less thorough, which has prevented society from finding the most cost-effective way to reduce motor vehicle emissions. In this paper, a systematic approach has been developed to estimate emission control costs of motor vehicles. The approach accounts for all emission control parts installed on vehicles, and the costs of these emission parts are estimated through their prices.

Using this approach and the information on emission control parts and their prices for new light duty vehicles sold in California in 1990, per-vehicle control cost and total control cost for all new light-duty vehicles have been estimated.

At the level of cost to vehicle manufacturers, per-vehicle control cost ranges from $220 to $1,450, depending on vehicle size and manufacturer. The sales-weighted average cost is estimated as $445 per vehicle. The total control cost of the 1990 light-duty vehicles sold in California is estimated to be about $698 million. At the level of cost to consumers, per-vehicle control cost ranges from $370 to $2,430, with a sales-weighted average of $748. The total control cost of the 1990 light-duty vehicles sold in California is estimated to be about $1.2 billion to consumers.
