"The draft report shows that overall emissions during 2007 increased by 1.4 percent from the previous year. This trend was due primarily to an increase in carbon dioxide emissions associated with fuel and electricity consumption. The total U.S. greenhouse gas emissions were about 7,125 million metric tons of CO2 equivalent. Overall, emissions have grown by 17.1 percent from 1990 to 2007."
