This potential dramatic increase is illustrated in Figure 5.6. By 2050, it is clear that
assumptions in GDP growth are critical to the overall emission, the technology assump-
tions having a second-order effect. In contrast to this overall pattern, the Depart-
ment of Trade and Industry (DTI) 2050 scenario assumes a fuel usage (from traffic
