GHG Emissions From Cars & Trucks Up 0.3% In 2006, Even As Overall Totals Slip - Detroit Free Press

[hatrack]

Greenhouse gas emissions from cars and trucks rose slightly in 2006, even as the United States cut its overall emissions by 1.5%, the U.S. Energy Information Administration said Wednesday.

The administration said the decline in man-made emissions to 7.08 billion metric tons was the first since 2001, and only the third since 1990.

Higher energy costs, a warmer winter that cut heating demand and a greater use of natural gas instead of coal by electric utilities drove the decline.

But carbon dioxide emissions from cars and trucks burning gasoline rose 0.3% to 1.19 billion tons, or about 17% of the U.S. total. Greenhouse gas emissions from U.S. vehicles have risen steadily since 1990, as a growing number of drivers traveling farther every year overwhelmed any reductions from more efficient vehicles
