Scenarios for a future energy supply

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

5.9 development of CO2 emissions

While CO2 emissions in New Zealand will decrease by 16% in the Reference scenario, under the Energy [R]evolution scenario they will decrease from around 30 million tonnes in 2009 to 2 million tonne in 2050. Annual per capita emissions will drop from 6.8 tonne to 2.3 tonne in 2030 and 0.3 tonne in 2050. 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 reduce emissions in the transport sector. The transport sector remains as the largest source of emissions. By 2050, New Zealand’s CO2 emissions are 8% of 1990 levels.
