This paper estimates that the Regional Greenhouse Gas Initiative (RGGI) has reduced CO2 emissions in New York State by nearly 5 million tons yearly on average by changing the fuel mixed used for electric generation. This analysis was performed using a database with fossil fuel generation data from the EPA's Air Markets Data Program (AMPD) supplemented with data from the EIA, NOAA, and U.S. Census. These results are important because RGGI is one type of program that would be permitted under EPA's recently proposed Clean Power Plan (CPP) rule. CPP explicitly encourages states to adopt regional trading programs like RGGI.
