Offsets Fall Short -- By Two-Thirds [2]
Only about a third of the climate-damaging [7]carbon dioxide released into the atmosphere in North America is offset by carbon-removing activities [8], a government report [9] 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.
