For the second year in a row, the EPA's data shows that the largest greenhouse gas polluter in the nation in 2011 was the Scherer power plant in Juliette. The plant, owned by Atlanta-based Southern Co., reported releasing more than 22 million metric tons of carbon dioxide, the chief greenhouse gas, in 2011. Heat-trapping gases from U.S. power plants fell 4.6 percent in 2011 from the previous year as plants burned less coal, the biggest source of greenhouse gas pollution, according to a new government report.
