 Currently, greenhouse gas emissions would need to be reduced by 7 Gt of carbon equivalent each year by 2050 to achieve 2oC stabilization.This requires power generation with CCS at 800 coal-fired power plants of 1 GW energy generation capacity,180 coal-synfuel plants, or natural gas plants worth 1,600 GW.In this scenario, one of the wedges, or 1 Gt of carbon is accounted for by CCUS.
