Do you think states will be able to enforce their own pollution restrictions? If so, life in blue states will get comparatively better - I say this as someone who remembers the awful Los Angeles pollution effects of the 1980s.
This is where things can get very complicated. CARB in California, the body that governs emissions, is only possible because the Clean Air Act gives California a specific waiver to enforce stricter emissions standards than the EPA. Is this overreach by the EPA, and if so, can CARB even continue to exist in California?
EDIT: It seems to me like it'll be business as usual for CARB but there's significant uncertainty here. The Supremacy Clause forbids the states from overwriting federal law, but if the EPA loses its enforcement powers altogether then nothing stops California from continuing to exert more stringent emissions standards. However it'll create a lot of uncertainty for automakers if the EPA and CARB is challenged on the grounds of regulating emissions and I'm not looking forward to what would happen next.
