Abolish the California waivers of federal pre-emption of auto emissions standards
There is now a big flap over the EPA's denial of California's request for a waiver of federal pre-emption of greenhouse-gas -- mainly CO-2 -- emissions standards for motor vehicles. The reason for the denial is that the greenhouse-gas problem is global rather than local in nature. I agree with the waiver denial. I support improvement of auto fuel efficiency and limitation of greenhouse gases as much as anyone, but IMO a California waiver is not a legal way to pursue these goals.
IMO the California waivers should be abolished altogether. I explain why in this comment thread on the Volokh Conspiracy blog.
