Dave Roberts consults various journalists and wonks about what to do now that a federal cap and trade bill appears dead. Terry Tamminen:

I would stop focusing on the glass that's empty and focus instead on the one that's full. We already have a price on carbon in 10 Northeastern states, at least as it pertains to the electricity sector, under RGGI [Regional Greenhouse Gas Initiative]. We are in the final stages of designing a similar cap-and-trade system in the majority of the Western states, and the Midwestern states have said they'll copy what we do. So by 2012, regardless of what Congress does, if we support these state actions -- which are much more deeply rooted and have a lot more political support and practical demonstration of success -- we are much more likely to have a price on carbon in the U.S. in the near-term.
