ABSTRACT

Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2006   [open pdf - 15MB]

This EPA national greenhouse gas inventory finds that overall emissions during 2006 decreased by 1.1 percent from the previous year. The report is the latest in an annual set of reports that the United States submits to the Secretariat of the United Nations Framework Convention on Climate Change, which sets an overall framework for intergovernmental efforts to tackle the challenge posed by climate change. "In 2006, total U.S. greenhouse gas emissions were 7,054.2 Tg CO2 Eq. Overall, total U.S. emissions have risen by 14.7 percent from 1990 to 2006, while the U.S. gross domestic product has increased by 59 percent over the same period (BEA 2007). Emissions fell from 2005 to 2006, decreasing by 1.1 percent (75.7 Tg CO2 Eq.). The following factors were primary contributors to this decrease: (1) compared to 2005, 2006 had warmer winter conditions, which decreased consumption of heating fuels, as well as cooler summer conditions, which reduced demand for electricity, (2) restraint on fuel consumption caused by rising fuel prices, primarily in the transportation sector and (3) increased use of natural gas and renewables in the electric power sector. Figure ES-1 through Figure ES-3 illustrate the overall trends in total U.S. emissions by gas, annual changes, and absolute change since 1990. Table ES-2 provides a detailed summary of U.S. greenhouse gas emissions and sinks for 1990 through 2006."
