Greenhouse gas emissions fell in the United States by 3.4 percent in 2012 from the previous year, the Environmental Protection Agency said Tuesday.
The EPA’s annual report on greenhouse gases found a 10 percent drop since 2005.
The 2012 inventory includes carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride, the EPA said. Together, the emissions were equivalent to 6,526 metric tons of carbon dioxide.
Electricity generation accounted for 32 percent, the largest portion, of the emissions, followed by transportation and industry.
