Right now, the Obama Administration is taking action to strengthen fuel efficiency and carbon pollution standards for new vehicles sold in the United States. In July 2011, President Obama directed the U.S. Department of Transportation (DOT) and Environmental Protection Agency (EPA) to establish joint fuel efficiency and pollution standards for new cars and trucks that will reach the equivalent of 54.5 miles per gallon (mpg) and emit 163 grams of carbon dioxide per mile (g/mi) in 2025. The new standards are fleet average requirements, which mean that some vehicles would have higher fuel efficiency and some would be lower.
Raising fuel efficiency standards to 54.5 mpg and setting a 163 g/mi standard will deliver significant economic, environmental, and national security benefits. It will save 23 billion gallons of oil in 2030 and reduce heat-trapping carbon pollution by 280 million metric tons – the equivalent of having 40 million fewer vehicles on the road in that year.
