Big US Carbon Footprints Lie East Of Mississippi

Nine of the 10 US urban areas that release the most greenhouse gases per person lie east of the Mississippi River, a study showed on Thursday. "A north-south divide is also apparent," said the report issued by two think tanks, the New York-based Regional Plan Association and the Washington-based Brookings Institution. Seven of the largest emitters of greenhouse gases are in the south, including two cities each in Tennessee, Ohio and Kentucky, it said.
