Multi-criteria Approaches to Ancillary Effects: The Example of E-Mobility

In this chapter we apply the ancillary benefit approach to the assessment of stakeholders’ attitudes towards e-mobility. The attitudes of stakeholders depend on a lot of different factors and the list of factors differs between the stakeholders. Hence, for an appropriate assessment of decarbonization of the transport sector it is necessary to consider a broad range of factors including the weighting or relevant factors by actors. Using a multi-criteria approach we show that stakeholders, like car users and vehicle manufacturers, will show resistance if they are urged to go for e-mobility. Since the assessment of the characteristics of e-mobility is linked with high uncertainty, we conducted intensive sensitivity analyses. According to these analyses it is difficult to cause a shift in the attitude of car users towards electric vehicles, since electric vehicles have a lot of disadvantages for the car users (including loss of comfort). According to our assessment, hybrid cars face less resistance since the technology is linked with more benefits/less negative effects for the stakeholders than e-mobility
