U.S. Energy-Related Carbon Dioxide Emissions Increased in 2002
U.S. emissions of carbon dioxide from burning fossil fuels increased by 1.3 percent in 2002, according to preliminary estimates by DOE's Energy Information Administration (EIA). Total U.S. energy-related carbon dioxide emissions grew 16 percent over the 1990 to 2002 period. Emissions of carbon dioxide from fossil fuels account for more than 80 percent of U.S. greenhouse gas emissions and are a good indicator of trends in total U.S. greenhouse gas emissions.
A slowing economy caused U.S. carbon dioxide emissions to decline by 1.4 percent in 2001, but a combination of higher economic growth, a colder winter, a warmer summer, and overall higher electrical demand—plus an increased burning of coal and natural gas to meet that demand-caused emissions to return to their previous growth rate in 2002.
