GREENHOUSE GAS EMISSIONS IN THE U.S.ROSE 1.4% IN 2007,EIA FINDS,AS U.S.STATES AND REGIONS DEVISE PRELIMINARY PLANS TO REVERSE THE TREND

摘要

Total U.S.greenhouse gas emissions in 2007 increased 1.4% above 2006 levels,the Energy Information Administration(EIA)reported recently in Emissions of Greenhouse Gases in the United States 2007.The increase was attributed mostly to higher carbon dioxide emissions.Increased demand for heating and cooling in buildings,due to unfavorable weather patterns,and an increase in electricity demand,with a related drop in hydropower generation capacity,led to a greater reliance on fossil fuels for generation.Other greenhouse gas emissions also increased,the EIA said,but their relative contribution to total emissions growth was small compared to carbon dioxide,which accounted for 80% of total U.S.emissions in 2007.
