Moving from principles to action for energy supply that mitigates against climate change requires a long-term perspective. Energy infrastructure takes time to build up; new energy technologies take time to develop. Policy shifts often also need many years to take effect. In most world regions the transformation from fossil to renewable energies will require additional investment and higher supply costs over about twenty years

development of CO2 emissions

Whilst North America’s emissions of CO2 will increase by 42% under the Reference Scenario, under the Energy [R]evolution Scenario they will decrease from 6,430 million tonnes in 2005 to 1,060 m/t in 2050. Annual per capita emissions will drop from 14.7 tonnes to 1.8 t. In spite of the phasing out of nuclear energy and increasing demand, CO2 emissions will decrease in the electricity sector. In the long run efficiency gains and the increased use of renewable electricity in the transport sector will even reduce CO2 emissions there. With a share of 46% of total CO2, the transport sector will be the largest source of emissions in 2050.
