Gov't: U.S. Greenhouse Gases on Rise Fri Oct 31,10:41 PM ET
WASHINGTON - Greenhouse gas emissions in the United States rose by 0.5 percent in 2002, the Energy Department reported Friday.
Carbon dioxide emissions from burning fossil fuels, which account for 83 percent of all greenhouse gas emissions, rose by 0.8 percent from 2001 levels. Many scientists believe that carbon dioxide and other industrial emissions trap heat in the atmosphere, much as a greenhouse does.
Among the other 16 percent of greenhouse gas emissions, methane and nitrous oxide, the main two, declined 2.7 percent. Those of hyrdofluorocarbons, perfluorocarbons and sulfur hexafluoride increased 6 percent.
The report by the Energy Department's Energy Information Administration attributed the rise in carbon dioxide emissions to growth in population and energy consumption.
From 1990 to 2002, U.S. greenhouse gas emissions increased at an average annual rate of 0.9 percent.
On Thursday, the Senate rejected a bill to restrict emissions of carbon dioxide and other heat-trapping gases. The vote was the Senate's first on the subject in more than six years. __
