While CO2 emissions in India will increase under the Reference Scenario by a factor of 5.4 up to 2050, and are thus far removed from a sustainable development path, under the Energy [R]evolution Scenario they will increase from the current 1,074 million tonnes in 2005 to reach a peak of 1,820 m/t in 2030. After that they will decrease to 1,660 m/t in 2050. Annual per capita emissions will increase to 1.3 tonnes/capita in 2030 and fall again to 1.0 t/capita in 2050. In spite of the phasing out of nuclear energy and increasing electricity demand, CO2 emissions will decrease in the electricity sector.

After 2030, efficiency gains and the increased use of renewables in all sectors will soften the still increasing CO2 emissions in transport, the power sector and industry. Although its share is decreasing, the power sector will remain the largest source of emissions in India, contributing 50% of the total in 2050, followed by transport.
