Under each RGGI state's CO2 Budget Trading Program, sources (fossil-fueled power plants 25MW and larger located within the RGGI participating states) are required to possess CO2 allowances equal to their CO2 emissions over a three-year control period.
A CO2 allowance represents a limited authorization to emit one ton of CO2 , as issued by a respective State. Each RGGI state's environmental regulatory agency uses RGGI COATS to determine compliance with state CO2 Budget Trading Program regulations, by comparing a source’s covered emissions with the allowances held in their compliance account.
The RGGI program is currently in its fourth three-year control period. Three-year control periods have proceeded as follows:
|Three-Year Control Period||Start Date||End Date|
|Fourth Control Period||Jan. 1, 2018||Dec. 31, 2020|
|Third Control Period||Jan. 1, 2015||Dec. 31, 2017|
|Second Control Period||Jan. 1, 2012||Dec. 31, 2014|
|First Control Period||Jan. 1, 2009||Dec. 31, 2011|
The RGGI participating states are Connecticut, Delaware, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. The state of New Jersey participated in the first control period.
Compliance is evaluated at the end of each three-year control period. Starting in the third control period, the RGGI states have also conducted interim control period compliance, which requires each CO2 budget source to hold allowances equal to 50 percent of their emissions during each interim control period (the first two calendar years of each three-year control period).
