About the Regional Greenhouse Gas Initiative
The Northeast and Mid-Atlantic states participating in the second RGGI control period (Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont) have implemented the first mandatory market-based regulatory program in the U.S. to reduce greenhouse gas emissions. The 2014 RGGI cap is 91 million short tons. The RGGI cap then declines 2.5 percent each year from 2015-2020.

RGGI is composed of individual CO2 budget trading programs in each state, based on each state’s independent legal authority. A CO2 allowance represents a limited authorization to emit one short ton of CO2, as issued by a respective state. A regulated power plant must hold CO2 allowances equal to its emissions to demonstrate compliance for each three-year control period. RGGI’s second control period began on January 1, 2012 and extends through December 31, 2014. For more information visit
