Yes there is, 49 states must seek policy exemptions from the EPA and win approval for them, while California has no such burden. CA gets a perpetual exemption allowing them freedom no other state gets. Edit: I was actually wrong here, no other state may even ask for a waiver. > This power is reserved alone for California, and it only covers pollution from cars. No other state can ask for a waiver. (In all of federal law, this might be the only time that a specific state is given special authority under such a major statute.) https://www.theatlantic.com/science/archive/2017/03/trump-california-clean-air-act-waiver-climate-change/518649/ https://www.theatlantic.com/science/archive/2017/03/trump-ca...
