development of CO2 emissions
Whilst emissions of CO2 will increase by 35% under the Reference scenario by 2050, under the Energy [R]evolution scenario they will decrease from 2650 million tonnes in 2007 to 532 million t in 2050. Annual per capita emissions will drop from 7.8 t to 1.7 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 reduce emissions in the transport sector. With a share of 40% of total CO2 in 2050, the power sector will drop below transport and other sectors as the largest sources of emissions.
The advanced Energy [R]evolution scenario reduces energy related CO2 emissions about 10 to 15 years faster than the basic scenario, leading to 3.9 t per capita by 2030 and 0.8 t by 2050. By 2050, Transition Economies ́s CO2 emissions are 6% of 1990 levels.
