Argument: The Chicago Climate Exchange is a success and model
Jason Margolis. "My Kind of Down Chicago Climate Exchange paves the way for U.S. emissions trading". 14 Jun 2005 - "City officials are not sitting idly by waiting to see if or when such things could happen. This spring, Oakland became the second U.S. municipality to join the Chicago Climate Exchange (CCX) -- North America's first and only voluntary, but legally binding, emissions-trading market.
Since trading began in 2003, CCX has grown to include 90 participants. Its members include private companies -- Ford Motor Co., IBM, and Motorola, Inc., to name a few -- as well as universities, nongovernmental organizations, and the city whose name it bears."
