EPA's
Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2010 is the agency's 17th annual U.S. greenhouse gas inventory, which tracks emissions and provides historical data. The reports says that an overall emissions increase of 3.2 % from 2009 to 2010 was caused by an increase in energy consumption across all economic sectors. In addition, total emissions of the main gases (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride) increased by 10% from 1990 to 2010.
