Regional Greenhouse Gas Initiative (RGGI)

About RGGI

The Regional Greenhouse Gas Initiative (RGGI) is a multi-state, market-based program that establishes a regional cap on carbon dioxide (CO2) emissions and requires fossil fuel power plants with a capacity greater than 25 megawatts (MW) to obtain an allowance for each ton of CO2 emitted annually. Power plants may comply by purchasing allowances from quarterly auctions, other generators within RGGI, or through projects that offset CO2 emissions. States use the proceeds from the CO2 allowance auctions to invest in programs to help further reduce CO2 and other greenhouse gas pollution, spur clean and renewable energy, and provide rate relief on energy bills. RGGI is a cooperative effort among 11 states: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont - to reduce greenhouse gas emissions. Launched in 2005, RGGI was the first mandatory greenhouse gas "cap-and-invest" program in the United States. To learn more about the initiative, visit RGGI.

New Jersey Auction Results

The first quarterly RGGI CO2 auction of 2024 took place on March 13th, allocating a total of $71+ million to New Jersey in 2024 for investment in clean energy and greenhouse gas reduction strategies in the State. The three agencies, New Jersey Department of Environmental Protection, New Jersey Board of Public Utilities, and New Jersey Economic Development Authority released the RGGI Strategic Funding Plan pdf identifying how the RGGI auction proceeds will be distributed for the 3-year funding period (years 2020 through 2022). To learn more about how the agencies develop this plan and how they plan to implement it, visit RGGI.

RGGI member states have realized numerous benefits including a significant reduction in CO2 emissions and a decrease in electricity prices and have realized over $1.83 billion in lifetime energy bills savings from investments of proceeds in 2019.
