Fuel Economy Standards are regulations set by governments to improve the average fuel efficiency of vehicles. These standards aim to reduce the amount of fuel consumed by cars and trucks, which helps lower greenhouse gas emissions and combat climate change. By requiring manufacturers to produce more fuel-efficient vehicles, these standards encourage the development of advanced technologies and cleaner energy sources. In the United States, the Environmental Protection Agency (EPA) and the Department of Transportation (DOT) work together to establish these standards. Automakers must meet specific fuel economy targets for their fleets, which can lead to cost savings for consumers and a healthier environment for everyone.
