The Corporate Average Fuel Economy (CAFE) is a set of regulations in the United States aimed at improving the average fuel efficiency of cars and trucks. Established by the Energy Policy and Conservation Act in 1975, CAFE standards require manufacturers to meet specific fuel economy targets for their fleets. This helps reduce oil consumption and greenhouse gas emissions, promoting a cleaner environment. To comply with CAFE standards, automakers must design vehicles that achieve higher miles per gallon (MPG) ratings. The regulations encourage innovation in automotive technology, leading to the development of more efficient engines and alternative fuel vehicles. Ultimately, CAFE plays a crucial role in shaping the future of transportation.
