This article reviews past studies on the long-term CO2 abatement strategy dealing with electric technologies and thereby attempts to draw sound understandings of effectiveness of those measures. It is widely known that electrification of final energy uses plays an important role to mitigate CO2 emissions through curbing fossil fuel consumption. Electrification of thermal demand by high-efficient heat-pump technologies is considered as a realistic example, while electric vehicles including plug-in hybrid vehicles are getting higher expectations as an alternative in the transportation sector. It is of crucial importance, therefore, to carefully analyze the potential of CO2 emission reductions by these measures and to establish viable long-term strategies taking them fully into consideration. The author provides a numerical representation of such strategy development up to the year 2050.
