The Energy Information Agency reported the CO2 emissions from fossil fuel combustion for the seven countries in 2008 with the highest emissions. These values, reported as million metric tons of carbon equivalent, are 6534 (China), 5833 (United States), 1729 (Russia), 1495 (India), 1214 (Japan), 829 (Germany), and 574 (Canada).
