CO2 allowances are issued by each RGGI State in an amount defined in each state's applicable statute and/or regulations. Together, all the CO2 allowances issued by all the RGGI States comprise the RGGI cap.
For the second three-year control period (2012-2014), the CO2 emissions cap for the nine-state RGGI region (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont) was 165 million short tons in 2012 and 2013 and 91 million short tons in 2014. The 2014 RGGI adjusted cap for the nine-state region was 82.8 million. 82.8 million was the number of CO2 allowances allocated by the RGGI states for 2014.
