It’s not really a state rights thing though: my state is not allowed to do something like that on its own
This is a federal thing that there’s a specific exception for California and the rest of us can only follow them or stick to federal standards
Articles keep linking this back to the clean air act but I don’t remember reading where the exception is. If it’s in the clean air act, I don’t see how Trump can change that: it has to be Congress. If it’s an EPA regulation or executive exception, that’s another story, but hopefully would at least be time consuming
Clean Air Act empowers the EPA to regulate air pollution from motor vehicles. To promote uniformity, the law generally bars states from regulating car emissions.
the Clean Air Act …. requires the EPA to grant California a waiver so it can continue to apply its own regulations
Other states can’t set their own standards, but they can opt to follow California’s motor vehicle emission regulations
