Since humans’ activities contribute to climate change it is important to change behavior. Switching to a hybrid/plugin/electric vehicle (HEV/PHEV/EV) for personal transport can be one way. In this study the intention to switch to a HEV/PHEV/EV is studied from the theoretical framework of the moral norm-activation theory of altruism (Schwartz, 1977) and the Value-Belief-Norm (VBN) Theory of environmentalism (Stern et al., 1999). Data was collected using a survey to three groups, alternative fuel vehicle owners (AFV, mainly E85/ethanol), fossil fuel vehicle owners (conventional vehicles, CV), and hybrid/plugin/electric vehicle owners (HEV/PHEV/EV). A SEM model was proposed, and tested on the subsamples of CV and AFV owners, of a hierarchical process of influence from the more general (e.g. values) to the more specific (e.g. beliefs, norms) and finally the intention. The results supported the proposed norm …
