Quantifying the total societal benefits of electric vehicles. This would mean comparing the externality related benefits of electric vehicles in comparison to internal combustion engines. Also, the study has to be based in the particular region – India. The cost comparison could be the total lifecycle analysis and would include a variety of parameters. One of the features of the dissertation could be the greenhouse gas reduction potential of electric vehicles and would enable to compute the various environment-related externalities in monetary terms, although it is realized that the limitations of such an analysis would mean some of the environmental externalities are complex and difficult to quantify. Also, the energy mix of a particular region would have a direct impact on the emissions generated by the use of electric vehicles.
