We learned in my natural resources class that national agencies that sound like they exist to protect the environment sometimes have a funny way of showing it. For example, the National Forest Service. National Forests are great, right? Let's protect them. Or, let's be the biggest road-building and timber harvesting arm of the federal government.
So I guess maybe it's not surprising that the EPA--that would be the Environmental Protection Agency, kind of hard to screw that one up--is currently arguing in a lawsuit against a slew of states and cities that it can refuse to regulate carbon dioxide emissions from new motor vehicles. This agency view won out at the appellate level, and the Supreme Court is taking up the issue this morning.
I fully understand the argument that federal agencies, as an arm of the executive branch, can be vehicles for policy that can change from administration to administration. But regulating CO2 emissions on new cars? Come on. How can that still be questioned?
