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 China’s emissions of CO2 will almost triple under the Reference Scenario, under the Energy [R]evolution Scenario they will decrease from 4,400 million tonnes in 2005 to 3,200 m/t in 2050. Annual per capita emissions will drop from 3.4 tonnes to 2.3 t. In spite of increasing demand, CO2 emissions will decrease in the electricity sector. In the long run efficiency gains and the increased use of renewable electricity in vehicles will even reduce CO2 emissions in the transport sector. With a share of 50% of total CO2 in 2050, the power sector will remain the largest source of emissions.
