6.7 development of CO2 emissions

6 key results |

Whilst the South Korea’s emissions of CO2 will decrease by 5% under the Reference scenario, under the Energy [R]evolution scenario they will decrease from 501 million tonnes in 2009 to 120 million tonnes in 2050. Annual per capita emissions will fall from 10.5 tonnes to 2.6 tonnes. 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 36% of total CO2 in 2050, the power sector will remain the largest sources of emissions.

DEVELOPMENT OF CO 2 EMISSIONS, PRIMARY ENERGY CONSUMPTION

The Advanced Energy [R]evolution scenario reduces energy related CO2 emissions about ten to 15 years faster than the basic scenario, leading to 7.1 tonnes per capita by 2030 and 0.9 tonnes by 2050. By 2050, South Korea’s CO2 emissions are 19% of 1990 levels.

6.8 primary energy consumption Taking into account the above assumptions, the resulting primary energy consumption under the Energy [R]evolution scenario is shown in Figure 6.11). Compared to the Reference scenario, overall energy demand will be reduced by 54% in 2050. Around 44% of the remaining demand will be covered by renewable energy sources.

The Advanced version phases out coal and oil about 10 to 15 years faster than the basic scenario. This is made possible mainly by replacement of coal power plants with renewables after 20 rather than 40 years lifetime and a faster introduction of electric vehicles in the transport sector to replace oil combustion engines. This leads to an overall renewable primary energy share of 26% in 2030 and 58% in 2050. Nuclear energy is phased out in the basic Energy [R]evolution scenario after 2035 and in the Advanced Energy [R]evolution after 2025.
