The Twin Cities are in the hands of two progressive mayors intent on doubling the metro region’s eco-efforts. Coleman and Rybak, elected in 2005 and 2001 respectively, have both made sustainability a priority — Minneapolis, for instance, doles out climate change grants to neighborhood organizations, while St. Paul created its own hybrid car-sharing program. Together, the two leaders have created an annual sustainability report and a green manufacturing initiative, and they’re bringing bike-sharing to town. It’s all part of an effort, they say, to make theirs the most livable cities in the country.
