I bought a Metrocard for the New York subway recently and it was colored green, not the usual black. Nice. Then I flipped it around and there it was. A message from the MTA : “Your carbon footprint is 1/4 of the national average!”
Cities with mass transit are greener than those without one, the suburbs and the exurbs. Which are the greenest cities in the US? Europe? Asia? Latin America?
