CO2 emissions from energy use dropped in U.S. last year

Carbon dioxide emissions went the way of the U.S. economy last year--which, in this case, is good news.

The EIA says the overall 2.8 percent dip in carbon dioxide (CO2) emissions is likely linked to a combo of the slumping economy and high fuel prices. [More] (link)
