Last March, the Trump administration announced that it would takeincreased Corporate Average Fuel Economy (CAFE) standards. That year is up, and the expected result is likely to involve the courts.
The EPA is expected to reject the fuel economy standards put in place at the end of the Obama administration, Reuters reports. Scott Pruitt, the current EPA administrator, is set to sign a declaration this weekend that will confirm the decision to change the standards, which affects vehicle efficiency for 2022 through 2025.
Currently, the goal is to increase CAFE regulations to approximately 50 mpg by 2025. It's important to note that CAFE fuel economy is measured differently than the numbers you see on window stickers. Real-world average economy is closer to 40 mpg. CAFE figures include adjustments that cover things like automakers' use of environmentally friendly refrigerant and other things that don't factor into the fuel economy figures most consumers see.
Originally, the EPA looked at the figures again just before the changing of the presidential guard and determined that it would , despite belief that the regulations could actually be strengthened. Past EPA estimates believed that the current 2025 standards would decrease greenhouse gas emissions by 540 million metric tons and save consumers upwards of $1,500 per vehicle.
California is where the potential legal battle begins. California has a great deal of power when it comes to setting its own environmental standards, some of which end up affecting how cars are developed nationwide. If the EPA reverses course but California does not, automakers could very well continue to build cars to higher fuel economy standards because trying to build the same cars to two different standards would be a right pain.
Environmental groups and other states have shown support for California's decisions in the past, and could well band together to challenge whatever new regulations the EPA decides upon. The EPA did not immediately return a request for comment.
Automakers are kind of caught in the crossfire here, even though they're also shooting. While automakers would like to save money by rolling back lofty MPG goals and appealing to consumers' current desires for larger, thirstier vehicles, they also don't want confusion between states, instead preferring to work with one single nationwide standard.
The EPA could well go nuclear and attempt to rescind California's ability to set its own standards, which was established in Section 177 of the Clean Air Act. California had some mild (read: severe) pollution issues, so when the federal government got around to dealing with the same issue, it let California continue to set its own standards.
It remains the only state that can mandate its own vehicle emissions standards, and several states have since decided to adhere to stronger California regulations over weaker federal ones. It would be a difficult path to take, because it would require changes to the Clean Air Act, but it's one that Pruitt has not explicitly shot down.
