It's a set of regulations in the United States that are designed to improve the average fuel economy of cars and light trucks sold in the country. These regulations are enforced by the National Highway Traffic Safety Administration (NHTSA).
Here are some key things to know about CAFE:
* Fuel Economy Standards: CAFE sets specific fuel economy targets for each manufacturer based on the average fuel economy of their fleet of vehicles.
* Penalties for Non-Compliance: Manufacturers that don't meet the CAFE standards face financial penalties.
* Incentivizing Fuel Efficiency: These regulations have encouraged car manufacturers to develop more fuel-efficient vehicles, leading to a decrease in fuel consumption and greenhouse gas emissions.
The CAFE standards have been in place since 1975 and have been gradually tightened over time. The goal is to improve fuel efficiency and reduce dependence on foreign oil.
