A half-century of regulation has greatly increased the fuel efficiency of US-made cars.
Do high fuel economy requirements make the US auto fleet less safe? The Trump administration says yes and is moving to freeze these standards, but auto experts and US car makers disagree.
The bad old days of gas lines in the 1970s and shortages led to the creation of fuel economy rules.
The Trump administration’s move to freeze fuel economy standards reflects a sea change in American energy policy first born during an era of oil shortages and environmental crises.

Law scholars from California unpack the legal questions raised by the Trump administration’s plan to roll back mileage standards and revoke California’s ability to set more stringent rules.
Customers line up to buy gasoline in San Jose, California, on March 15, 1974, during an Arab oil embargo. The crisis spurred enactment of the first U.S. vehicle fuel economy standards.
Since the federal government started setting fuel economy standards, US-built cars have doubled their fuel efficiency, saving money for consumers and reducing pollution.
Fuel economy and air pollution regulations have lowered pollution and pushed industry to innovate.
The Trump administration announced a plan to relax fuel economy standards, but well-designed regulations can drive clean car innovations that make U.S. industry globally competitive.
An emissions cap could save Australians up to A$500 each year in fuel costs.

The Australian government is considering a cap on car emissions, and the savings in fuel and health costs mean there’s no reason to delay.
In 2015, gas prices fell below $2 per gallon in Moscow Mills, Missouri. The trend of low gas prices across the United States delay a signature Obama proposal to reduce emissions from cars and trucks.
Faced with stringent fuel economy standards but cheap gas, automakers may seek to delay CAFE rules. What’s the best way to reevaluate these emissions-cutting rules?
Going down: Prices in Texas in November 2015.
With cheaper gas, consumers are buying fewer fuel-efficient vehicles – a step backwards on climate, energy security and upkeep of our highway and bridges.
While the higher gas mileage may lead people to drive a green car more often, its other attributes may be less appealing.
