Offsets Fall Short — By Two-Thirds

Only about a third of the climate-damaging carbon dioxide released into the atmosphere in North America is offset by carbon-removing activities, a government report said.

According to the new U.S. study, North America released 1,856 million metric tons of carbon into the air in 2003 – 85 percent from the United States, 9 percent from Canada and 6 percent from Mexico.At the same time, growing vegetation and other sources took in about 500 million metric tons of carbon.
