NYC has a higher share of transit riders and walkers than any city, also a decent number of bikes, so much fewer VMT per capita. Also, larger multi-unit buildings are more efficient to heat than single family houses. So although NYC's environmental impact is huge, its residents have about half as much impact per capita as average Americans. Incidentally, CA has lower than average environmental impact because the temperate weather means less energy used for heating and cooling. (Plus the higher efficiency standards and higher population density)
