Reduced emissions of CO2, NOx, and SO2 from U.S.

Since 1997, an increasing fraction of electric power has been generated from natural gas in the United States. Here we use data from continuous emission monitoring systems (CEMS), which measure emissions at the stack of most U.S. electric power generation units, to investigate how this switch affected the emissions of CO 2, NOx, and SO 2.Per unit of energy produced, natural gas power plants
