limiting greenhouse gases in the evergreen state

NPR's Morning Edition reports today on efforts in Seattle to reduce greenhouse gas emissions. It's a topic that has gotten a lot of attention lately, but I thought this story did a particularly good job of laying out the challenges of moving a sprawling American city towards energy efficiency. Part of the solution has been adopting the California standards for greenhouse gases - despite the fact that the Bush administration is currently challenging those regulations in court! What a bizarre position to take, for a Republican administration that claims to support states' rights as well as good stewardship of the environment. If the feds won't even let Californians clean up their own air, how can my fellow Washingtonians hope to solve the problem? (That's a rhetorical question, but if you have any good answers, send them along anyway.)
