Whilst emissions of CO2 in the United States will increase by over 50% under the Reference Scenario, under the energy [r]evolution scenario they will decrease from 5,600 million tons in 2003 to 1,550 m/t in 2050. Annual per capita emissions will drop from 19.2 t to 3.7 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 biofuels will even reduce emissions in the transport sector. Transport will take over as the largest source of CO2 emissions in the Unites Sates, with a share of 62% in 2050.
