How green is your city?

Via Beth Filar-Williams, the National Resources Defence Council has ranked U.S. cities by environmental factors. The study ranks 67 large (population 250,000+), 167 medium (100-250k), and 405 small (50-100k) cities on nine factors, including standard of living, water management, transportation, and environmental participation. Seattle comes out on top for big cities; San Francisco, 2nd; Chicago, 10th.

Other leaders include Madison, Wis. (medium) and Bellingham, Wash. Bottom of the pack: Lexington, Ky., Paterson, N.J., and Pine Bluff, Ark.
