"The Bush Administration's unparalleled financial, international and domestic commitment to reducing greenhouse gas emissions is delivering real results," said EPA Administrator Stephen L. Johnson. "As America's economy continues to grow, our aggressive yet practical strategy is putting us on track to reach President Bush's goal to reduce our nation's greenhouse gas intensity 18 percent by 2012."
Total emissions of the six main greenhouse gases in 2005 were equivalent to 7,260 million metric tons of carbon dioxide. These gases include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. The report indicates that overall emissions have grown by 16 percent from 1990 to 2005, while the U.S. economy has grown by 55 percent over the same period.
