CO2 emissions declining without the "help" of legislation
EIA FOR IMMEDIATE RELEASE MAY 5, 2010
In 2009, energy-related carbon dioxide emissions in the United States saw their largest absolute and percentage decline (405 million metric tons or 7.0 percent) since the start of U.S. Energy Information Administration's (EIA) comprehensive record of annual energy data that begins in 1949.
Today EIA released an analysis of the factors affecting this decline. "The large decline in emissions was driven by the economic downturn, combined with an ongoing trend toward a less energy-intensive economy and a decrease in the carbon-intensity of the energy supply," said EIA Administrator Richard Newell.
In addition to a decline in gross domestic product (GDP) in 2009 of 2.4 percent, the energy intensity of the economy (energy consumed per dollar of GDP) declined 2.4 percent and the carbon intensity of the energy supply (carbon dioxide per unit of energy consumed) declined by 2.3 percent. The latter two factors led to a decline in the overall carbon intensity of the economy (carbon dioxide per dollar of GDP) of over 4.5 percent between 2008 and 2009.
