June 13, 2007: U.S. Carbon Dioxide Emissions Declined in 2006
Factors that drove emissions lower include weather conditions that reduced the demand for heating and cooling; higher energy prices for natural gas, gasoline, and electricity that reduced energy demand; and the use of a less carbon-intensive fuel mix (more natural gas and non-carbon fuels) in the generation of electricity.
Through 2006, total U.S. energy-related carbon dioxide emissions have grown by 17.9 percent since 1990. Energy-related carbon dioxide emissions account for over 80 percent of U.S. greenhouse gas emissions.
