Through statutes or regulations based on the RGGI Model Rule, each state has established individual CO2 Budget Trading Programs based upon its own statutory or regulatory authority. Together, these compose a regional cap and market for allowances. Each state's CO2 Budget Trading Program limits emissions of CO2 from electric power plants, issues CO2 allowances and establishes participation in regional CO2 allowance auctions.
Below are links to each RGGI state's CO2 Budget Trading Program regulations and/or statutory authorities.
