Maryland’s “clean cars” plan to cut vehicle emissions might have some obstacles to overcome if a decision from the U.S. Environmental protection agency holds up. The EPA has decided that state efforts to reduce greenhouse gas emissions from cars prevent a consistent national standard for automakers to follow.

But some state officials, including many here in Maryland, say the government has been too slow to act, so it’s up to states. This argument is quite popular on the Web.

So what do you say?

Is this an arena that can be effectively regulated by states? After all, the gases that enter the atmosphere can’t be trapped by political borders.

Or do you think a state can play an effective, if symbolic, role in setting an example for the wider population?
