Sustainable Pittsburgh

From the Pittsburgh Post-Gazette: "Pittsburgh was into sustainability earlier than most cities and has a deep track record in sustainability and green design," said Donald K. Carter, director of the Remaking Cities Institute at Carnegie Mellon University.

"In fact, Pittsburgh was into sustainability before it was a word. Renaissance I in the late 1940s to the late 1960s included cleaning the air and water and creating Point State Park and Gateway Center out of rail yards and factories."

Reporter Bill Tolan documents the growth of the 2nd wave of Pittsburgh's sustainability movement, starting in 1993. He also highlights what he sees as the difference between "green" and "sustainable," which is that sustainability also focuses on the economically viable.
