(Washington, D.C. - April 16, 2007) The U.S. Environmental Protection Agency has released the national greenhouse gas inventory, which finds that overall emissions during 2005 increased by less than one percent from the previous year. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2005, was published after gathering comments from a broad range of stakeholders across the country.

"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.

EPA prepares the annual report in collaboration with experts from multiple federal agencies. This report is the latest in an annual set of reports that the United States submits to the Secretariat of the United Nations Framework Convention on Climate Change, which sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change.

The inventory tracks annual greenhouse gas emissions at the national level and presents historical emissions from 1990 to 2005. The inventory also calculates carbon dioxide emissions that are removed from the atmosphere by "sinks," e.g., through the uptake of carbon by forests, vegetation, and soils.
