Participating States

The ten states participating in RGGI -- Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont -- are implementing the first mandatory cap-and-trade program in the United States to reduce greenhouse gas emissions.

The authority of the individual states is the basis for the RGGI CO2 Budget Trading Programs. Through independent rules and/or regulations (based on the "Model Rule") each state limits emissions of CO2 from electric power plants, creates CO2 allowances and establishes participation in CO2 allowance auctions. Regulated power plants will be able to use a CO2 allowance issued by any of the ten participating states to demonstrate compliance with an individual state program.

In this manner, the ten individual state programs, in aggregate, will function as a single regional compliance market for CO2 emissions.
