In recent years, the transition toward more sustainable forms of mobility has taken on a central role in political, economic, and environmental debates. In this context, the adoption of electric and hybrid vehicles represents a crucial challenge for the future of the automotive sector, especially in countries like Italy, where the diffusion process remains partial. This thesis aims to analyse the main factors that influence Italian consumers’ intention and behaviour regarding the use of low-emission vehicles, adopting a multidimensional approach that integrates theoretical models, empirical evidence, and practical implications. Starting from a critical review of the literature, the study reconstructs and simplifies the contributions offered by major technology acceptance models (such as UTAUT2), integrating them with dimensions related to user experience and environmental awareness.
