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.

In addition to their individual CO₂ Budget Trading Programs, the RGGI states have established a variety of goals and commitments related to climate and energy. A summary of these goals and commitments can be found here.

Below are links to each RGGI state's CO₂ Budget Trading Program regulations and/or statutory authorities.
