This article from Grist looks at the environmental efforts being taken in Cleveland, a historically polluted and struggling Rust Belt city.
"Cleveland is one of a handful of cities in the Rust Belt -- including Pittsburgh, Milwaukee, Detroit, and Columbus -- that are reinventing the region as a sort of Green Belt."
"The movement here is largely rooted in nonprofit groups and citizen activists like Lefkowitz and GCBL, but the city government is doing its part. Cleveland was the second U.S. city to sign the U.N. Global Compact, a charter for businesses to align themselves with human rights, labor, environmental, and anti-corruption practices; it also hired a sustainability programs manager in 2005, slightly ahead of the sustainability curve. Last year, the American Public Transportation Association named Greater Cleveland's Regional Transit Authority the best transit system in America."
