Regional Greenhouse Gas Initiative

Regulated Sources

The RGGI CO₂ Budget Trading Programs regulate emissions from fossil fuel-fired power plants with a capacity of 25 MW or greater located within the RGGI States ("CO₂ budget sources" or "sources"). 

As of January 1, 2009, sources are required to possess CO₂ allowances equal to their CO₂ emissions over a three-year control period.  The first three-year control period took effect on January 1, 2009 and extended through December 31, 2011 for the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont. The second three-year control period took effect on January 1, 2012 and extends through December 31, 2014 for the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont.

A CO₂ allowance represents a limited authorization to emit one short ton of CO₂ from a regulated source, as issued by a participating state. CO₂ allowances are issued by each state in an amount defined in each state's applicable statute and/or regulations.

The table below shows:

• The number of CO₂ allowances issued by each state ("CO₂ Emissions Budget")
• Each state's share of the regional emissions cap
• The number of CO₂ budget sources located within each state

To view additional information about individual sources located within in a particular state click on the name of the state listed in the left-hand column of the table below.
