Where's Philadelphia?

Philadelphia is virtually nowhere in sight on the Natural Resource Defense Council's Smarter Cities project that ranks American cities based on a number of criteria relating to sustainability; not even the tallest "green" building in the world, the Comcast Center, could save it. Well, actually, it is number eight in the transportation criterea thanks to the Philly Car Share program that removed 330 municipal vehicles and approximately 1300 private vehicles from the city's roads, resulting in a supposed 40% reduction in vehicle use. While it does save the city money, does it really drastically reduce the environmental impact of automobiles? I'm not sure about the numbers, but from what I've seen, not every Philly Car share vehicle is a hybrid.

Anyway, take a look at the cities far smarter than Philadelphia and ponder what can be done to improve its record.
