The RGGI CO2 Budget Trading Programs regulate emissions from fossil fuel-fired power plants with a capacity of 25 MW or greater located within the RGGI States ("CO2 budget sources" or "sources"). The RGGI CO2 Budget Trading Program became effective as of January 1, 2009. CO2 budget sources 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 short ton of CO2 from a regulated source, as issued by a participating state. CO2 allowances are issued by each state in an amount defined in each state's applicable statute and/or regulations.
