Yesterday, the US EPA rejected California's bid to regulate vehicle greenhouse gas emissions. The reason given for rejecting California's request is the recently signed Energy Bill implements new CAFÉ standards across the country, thus eliminating the need for states to make their own laws on the issue. EPA Administrator Stephen Johnson said, "Under this unified approach the country will achieve significant reductions in greenhouse gas emissions. I believe this is a better approach than if individual states were to act alone." This decision by EPA will most likely bring about court battles and hearings on the Hill regarding the issue for states.
