Bloomberg gives himself a "57" on PlaNYC

In 2007, New York City Mayor Michael Bloomberg created not a few waves by unveiling PlanNYC, a 127-point plan to cut New York's carbon footprint by 30 percent by 2030. The signature initiative -- which drew almost all the heat -- was a congestion pricing plan to charge drivers entering certain parts of Manhattan. That plan died under fierce opposition from the state Assembly. Also struggling is a proposal to make the city's taxi fleet hybrid, overturned by Federal Judge Paul Crotty. Even so, at the three-year mark the city is calling its efforts "a great start."
