Here’s an item from earlier this month: Popular Science gave Chicago in the number-nine slot in its America’s 50 Greenest Cities feature.
Using data from the U.S. Census Bureau and the National Geographic Society’s Green Guide, the magazine evaluated 50 cities in four categories: electricity, transportation, green living and recycling / green perspective.
Portland, Ore., was number one, followed by San Francisco and Boston. Popular Science singled out Chicago for its 12,000 acres of parks and public green space; the city led the Midwest in the rankings, beating out Minneapolis (11) and Milwaukee (22).
Six cities got individual write-ups in the magazine for particularly sustainable urban design elements. Chicago’s (the second item in this slide show) described the cogeneration processes used in some city’s power plants.
