15 April 2009 — The U.S. Environmental Protection Agency has released the national greenhouse gas inventory, which found a 1.4 percent increase in overall emissions from 2006 to 2007.
Total greenhouse gas emissions in 2007 were equivalent to 7,150 million metric tons of carbon dioxide, according to an EPA release. The report measured carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.
Overall emissions have grown by 17.2 percent from 1990 to 2007. This was due primarily to an increase in carbon dioxide emissions associated with fuel and electricity consumption, according to the report.
