We sought the advice of academic, non-profit and government experts to come up with a broad set of criteria by which to measure and compare sustainability efforts in cities across the U.S. The ranking scheme, developed with the help of a scholar from Yale’s School of Forestry and Environmental Studies, was intended as a tool for identifying, for the purpose of spotlighting, those cities that are taking the lead in addressing the major environmental challenges of our time, from global warming to clean air and water.
The cities were evaluated based on air quality, energy production and conservation, recycling, transportation, water quality, etc. More details on the criteria are provided here.
The Top 15 large cities list is dominated by the West - 9 cities, with 6 from California. Seattle, WA tops the list, followed by San Francisco, CA and Portland, OR. 2 cities from the Northeast, Boston and New York as do the two Texas cities - Austin and Dallas. Finally, two cities from the Midwest complete the list - Chicago, IL and Columbus, OH. Wow... Columbus makes it to the top 15 large sustainable cities in the US...at the 15th spot!

Except for the Texas cities, no other city from the South makes it to the Top 15. Louisville, KY takes the 21st spot, making it the only southern city to feature in the Top 30. Well, Louisville is just a few miles away from Cincinnati, so it does not represent a typical city from the South.
Madison, WI tops the list for medium cities, followed by Santa Rosa, CA and Fort Collins, CO (again from the West). Another Western city captures the top spot for small cities - Bellingham, WA.
The profile on Columbus claims that the city and the Mayor are working towards expanding the bike routes in the city to make Columbus the "biking capital" of the country by 2012.
