FIGURE 9 ANNUAL GREENHOUSE GAS EMISSIONS, 1970–2010
imageGreenhouse gases from human activities include carbon dioxide from fossil fuel and industrial processes, carbon dioxide from forestry and other land use (FOLU), methane, nitrous oxide, and fluorinated gases. From 1970 to 2010, the nominal amount of all greenhouse gases increased. As a percentage of all greenhouse gases, carbon dioxide from fossil fuel and industrial processes increased from 55% to 65%, while fluorinated gases increased from 0.44% to 2%.
