Japan 2012

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

1.9 japan: development of CO2 emissions

Whilst Japan’s emissions of CO2 will decrease by 6% under the Reference scenario, under the Energy [R]evolution scenario they will decrease from 1,301 million tonnes (t) in 2007 to 298 million t in 2050. Annual per capita emissions will fall from 10.2 t to 2.9 t. In the long run efficiency gains and the increased use of renewable electricity in vehicles will even reduce emissions in the transport sector. With a share of 35% of total CO2 in 2050, the power sector will remain the largest sources of emissions

In the Advanced Energy [R]evolution scenario Japan can completely phase out nuclear power in 2012 and still reach its pledge of reducing Greenhouse gas emission by 25% below 1990 levels by 2020 with 24% reductions coming through domestic means, and the remaining sourced through flexible mechanisms internationally.
