Reviews of air quality standards should be based on scientific analysis and conclusions, but too often the EPA embraces an obvious politicization of the air quality standard-setting process that could mean unnecessary cost increases for consumers, job losses for workers, and less energy security for America.

A combination of cleaner gasoline and diesel fuels, modernized equipment and facilities, and more fuel efficient vehicles have helped reduce emissions of air pollutants by 62 percent between 1980 and 2013 – even as vehicle miles traveled went up over 95 percent.
