We have cut our carbon emissions more than any other country in the world in recent years — 7.7 percent since 2006. U.S. emissions fell 1.9 percent last year and are projected to fall 1.9 percent again this year, which will put us back at 1996 levels. It will not be easy to achieve the reductions Obama promised in Copenhagen — 17 percent (from 2005 levels) by 2020 — but that goal no longer looks out of reach, even in the absence of comprehensive legislation.
Why isn’t this extraordinary story a bigger deal in U.S. politics? You’d think Obama would be boasting about it! Turns out, though, it’s a little awkward for him, since several of the drivers responsible are things for which he can’t (or might not want to) take credit.
