Situated within the framework of sociotechnical transitions, this study analyzes the implementation of national e-mobility policy in Germany through the lens of actors operating across seven key fields. By integrating a policy mix analysis with empirical data from expert interviews, we explore how system challenges are perceived and negotiated. Using a sociotechnical transitions framework, we explore gaps in the current policy mix and advocate for a more integrated approach to address systemic deficiencies. The findings emphasize the role of intermediary actors in policy implementation and contribute to SDG 9 by identifying pathways to strengthen infrastructure and innovation in sustainable mobility.
