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 Developing Asia’s CO2 emissions will increase by a factor of 2.5 under the Reference Scenario, in the Energy [R]evolution Scenario they will decrease from 1,300 million tonnes in 2005 to 1,150 m/t in 2050. Annual per capita emissions will drop from 1.3 tonnes to 0.8 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 vehicles will stabilise CO2 emissions in the transport sector. With a share of 22% of total CO2 in 2050, the power sector will drop below transport as the largest source of emissions.
