Greenhouse gas emissions up for cars, trucks in 2006

Greenhouse gas emissions from cars and trucks rose slightly in 2006, even as the United States cut its overall emissions by 1.5%, according to the U.S. Energy Information Administration and reported by the Detroit Free Press.

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.
