Ask a Scientist: UCS Transportation Program Adds Equitable Mobility to its Portfolio

Union of Concerned Scientists

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. More than 20,000 Americans died prematurely in 2015 from tailpipe emissions, according to a 2019 study.
