The Star Tribune reported this afternoon that SustainLane.com, an online "people-powered guide to sustainable living" has ranked Minneapolis 7th on its 2008 U.S. City Rankings. The report surveyed the 50 most populous U.S. cities and evaluated each based on 16 areas of urban sustainability, such as water supply, air quality, transit and government initiatives among others. Minneapolis ranked especially well for its local food and agriculture and knowledge base and communications. You can see the rest of the breakdown on the chart. In the story, the folks at SustainLane call Minneapolis "bike-friendly" and a "Midwestern jewel of a city," and tout the Midtown Greenway and Mayor R.T. Rybak's green leadership.
