Historical Emissions (2000-2008)

PDF Print Email

Please use the scroll bars below to view historical CO2 emissions data from regulated power plants in Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont from 2000-2008. Quarterly emissions data for the current control period is available through the Emissions Report in RGGI-COATS.

Blue cells to the left show year-by-year emissions. Purple cells to the right show annual emissions expressed as "three-year averages" (i.e. average annual emissions between 2000 and 2002, rather than actual emissions for 2000, 2001, and 2002).

To view this spreadsheet in Excel, please follow this link: Excel Download (Updated 11/18/09). The Excel version also includes plant-specific emissions for each state.
