U.S. greenhouse gas emissions declined 1.5 per cent in 2006, says Department of Energy
Washington, D.C. – A report by the U.S. Department of Energy says that total U.S. greenhouse gas (GHG) emissions decreased by 1.5 per cent from 2005 to 2006, only the third time a decrease has been recorded since 1990. The total GHG emissions in 2006 were 7,075.6 million metric tons carbon dioxide equivalent.
However, total GHG emissions from the transportation sector rose 0.5 per cent from 2005 to 2006, and in 2006 were 407.5 million metric tons higher than in 1990.
Emissions of carbon dioxide from energy consumption and industrial process declined by 1.8 per cent in 2006, after having risen at an annual rate of 1.2 per cent per year from 1990 to 2005. The drop can be attributed to a decline in overall energy demand due to favourable weather patterns creating fewer heating and cooling-degree days, and a decrease in the carbon intensity of electricity generation, driven by the increased use of natural gas and greater reliance on non-fossil-fuel energy sources.
