Figure 1 Effect of the Kyoto Protocol (shown in blue) on (1) the projected total, worldwide emission of CO2; and on (2), the resulting concentration of the gas in the atmosphere (in parts per million by volume, ppmv), through the next 100 years. Emissions are in units of petagrams (1015 grams) of carbon, or equivalently, billions (109) of metric (2,200 lb) tons per year. In each figure the black reference line (labeled IPCC) is the projected scenario, called IS92a, developed by the Intergovernmental Panel on Climate Change. Shown for reference in the second figure is the pre-industrial CO2 concentration of roughly 275 ppmv.
