Part of combatting greenhouse gasses and climate change is making quality mass transit -- high speed subway and rail that doesn't get stuck in traffic.
The NYC subways (not counting busses) have 6 million trips per business day, essentially providing 1% of the nation's population with round trips. Yet, despite providing a green solution the system is vastly underfunded. The same seems to be true of Wash DC subway and Boston subway.
Much (most?) of the electricity that runs the NYC subway is from hydroelectric from Quebec Province in Canada thus a really green solution.
Stats for NYC itself are much more difficult to find.
