Local and state governments have outrun the federal government. The EPA has served notice that it will enact a rule requiring CO2 reductions by major emitters in the absence of major legislation. But it's a blunt instrument that is a little more difficult to use than a legislative remedy.

I'm passionate about restoring the efficacy of American democracy, making capitalism sustainable, prioritizing advances in technology, and seizing the opportunities to use that kind of innovation to help usher in a new economy that doesn't rely on carbon-spewing fossil fuels.
