Since September 2008, more than 100 bidders -- including electric utilities, manufacturers, financial institutions, environmental groups, and individuals -- have participated in the RGGI auctions for CO2 allowances. Trading volumes on national, regulated exchanges now match volumes in other established carbon markets, such as the Kyoto Clean Development Mechanism.  Overall, the 10 RGGI states have now auctioned more than 140 million allowances and raised a total of $432.8 million since the first RGGI auction in September 2008.

The proceeds will go to energy efficiency, clean and renewable energy technologies, and strategies to reduce greenhouse gases and create green jobs.  New York
