Figure 3 The effect of assumed technological advances on the course of CO2 emissions and concentrations through the next 100 years. The blue, steeply-rising curves show what would likely ensue were the energy technology that is employed, worldwide, to be restricted, on average, to what is available today . The black curve, from Figs. 1 and 2, is IPCC scenario IS92a, which assumes drastic changes in how electricity is generated and used. The dashed blue lines, for comparison, are emissions and concentrations paths consistent with a goal of holding the eventual CO2 concentration below a ceiling of 550 ppmv (about twice the pre-industrial level.)
