While I understand that the federal government has Commerce Clause powers and through administrations, can carry Congress' will when dealing with the environment (Chevron, EPA v. Mass), I was wondering how states deal with this. They have police powers in this area, but are there Supreme Court cases where petitioners argue against the state's power to regulate the environment?
I understand that the case dealt with CO2. However, it does enforce that the federal government has the power to regulate state environment.
How federalism and the environment? Like state statues against federal statutes? I'm assuming the federal government supersedes.
