The 2012-2016 Corporate Average Fuel Economy standards, better known under the acronym CAFE, mandate reaching 34.1 MPG by 2016, a number that many big players felt was too high. This led to a challenge in the courts, all the way to the U.S. Court of Appeal.
The U.S. Supreme Court decision on health-care will no doubt totally overshadow this less media-friendly legal decision, but the U.S. Court of Appeal actually upheld the federal CAFE standards:
The U.S. Court of Appeals in Washington dismissed challenges brought by states led by Texas and major industries including chemical, energy, utility, agriculture and mining companies as well as the National Association of Manufacturers.
The decision is a big win for the Obama administration, which plans to finalize the 2017-25 fuel-efficiency standards and greenhouse gas emissions limits by August. The new rules will hike requirements to 54.5 mpg by 2025.
This is great news, because while they are flawed, CAFE standards are what we have now to move things along. They don't say how automakers must increase efficiency, just by how much. The can then figure out what solution works best.
