"Portland, Oregon, a role model for cities in the United States, topped the 2006 SustainLane US City Rankings. Portland residents and businesses have teamed with politicians to ensure that quality of life remains superior, with an economy that increasingly integrates regional and renewable resources. Neighborhoods facilitate walking, cycling and shopping; downtown transit is free. The city bolsters local business and regional agriculture, while green buildings and park space are ample. Columbus, Ohio, at number 50, has some work to do to catch up, but has a few green surprises nevertheless." "How Green is Your City? quantitatively ranks the 50 largest US cities overall from comprehensive data and information based upon 15 standards, including: climate change policy and energy supply; green building; planning and land use; air and tap water quality; and public transit." "An analysis of each city considers policies, quality-of-life indicators and economic factors, providing kudos for successes and recommendations for challenges."--Jacket.
