Overall, US greenhouse gas emissions were 1.1 percent lower
during 2006 than the previous year, according to the latest
annual report from the US Environmental Protection Agency,
Emitted by the burning of the fossil fuels coal, oil and
gas for power, manufacturing and transportation, greenhouse
gases reduce the loss of heat into space, raising global temperatures.
The agency says that emissions of the main climate warming
gas - carbon dioxide - decreased in 2006 because Americans
burned less fossil fuels and used less electricity than they
did in 2005.
Compared to 2005, the winter of 2006 was warmer, which decreased
consumption of heating fuels and the summer was cooler, which
reduced demand for electricity, the EPA said.
Fuel consumption for transportation went down because of
rising fuel prices, the agency stated.
Finally, the increased use of natural gas and renewables
in the electric power sector also contributed to the lowering
of carbon dioxide emissions.
