Currently RGGI states include Connecticut, Delaware, Massachusetts, Maryland, Maine, New Hampshire, New York, Rhode Island and Vermont. New Jersey and Virginia are in the process of linking with RGGI.
The RGGI states hold a centralized quarterly, regional auctions of carbon allowances, with each state investing its share of auction proceeds into many diverse state clean energy, consumer benefit and other programs.
While the RGGI states voluntarily participate in the common carbon cap and auction platform, state choice is a key feature of the RGGI model. Each state decides how to invest auction proceeds based on its own strategic priorities and circumstances.
A majority of auction proceeds are invested by the RGGI states into energy efficiency (EE) and clean energy programs, with EE providing the most significant economic return per dollar invested. Proceeds are also invested in GHG abatement, direct bill assistance, green job training, climate resilience and administration. (Analysis Group, 2018)

RGGI, Inc. is the official website of the RGGI states for the RGGI auction program
The Georgetown Climate Center’s State Energy Analysis Tool provides key data on the RGGI states’ electricity profile, renewable energy growth and carbon reductions. This interactive online tool of publicly available reported energy data is an early, successful initiative of the RGGI Project Series, hosted by Georgetown since 2014. The Tool allows users to compare state-level data for all 50 states, assess benefits of capping emissions and tracking potential economic and other impacts. As RGGI nears its 10th anniversary this fall (2018), the Tool has been expanded to include the transportation sector.
The RGGI CO2 Allowance Tracking System (RGGI COATS) is RGGI, Inc.’s platform for recording and tracking each state's CO2 Budget Trading Program.
