Regional Greenhouse Gas Initiative

The Regional Greenhouse Gas Initiative (RGGI) is a cooperative effort by eleven Northeast and Mid-Atlantic states to limit greenhouse gas emissions from electricity generation. Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont, and Virginia are implementing the first mandatory cap-and-trade program in the United States to reduce greenhouse gas emissions.

Greenhouse Gases

For more than a century, concentrations of heat-trapping greenhouse gases (GHGs) like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) have been rapidly increasing in Earth’s atmosphere.
