The U.S. transportation sector is the nation’s largest contributor to greenhouse gases. Under the National Highway Traffic Safety Administration’s (NHTSA) newly proposed standards, automakers must boost fuel efficiency in passenger cars and light-duty vehicles every year – preventing more than 900 million tons of CO2, saving 88 billion gallons of gas through 2050, and putting $50 billion back in our pockets.
