Background and objective <p>Local municipalities are promoting active mobility (AM), such as cycling, walking, and using public transportation, in order to reduce CO₂ emissions and encourage physical activity. Despite the health and environmental benefits of AM, and the potential for cross-sectoral active transport measures, the ‘Health in All Policies (HiAP)’ approach is rarely considered in sustainable urban development. This study examines how administrative and political actors implement AM in line with HiAP, and the structural conditions or barriers that exist in this regard.</p> Methods <p>Guided expert interviews were conducted with nine employees from various areas of local government and two local politicians. The evaluation was carried out using structured qualitative content analysis.</p> Results <p>AM measures are primarily implemented in transportation and environmental policy-making processes. Although existing structures and collaborations facilitate their implementation, they are rarely used to systematically incorporate health objectives in the spirit of HiAP. This is due to reactive political support and a&#xa0;lack of awareness of the need to implement AM in the context of health across all policy areas. Furthermore, the health department is not involved in matters of mobility.</p> Conclusion <p>The limited involvement of the public health service and the lack of an implementation-oriented perspective for AM currently restrict the potential of HiAP. Therefore, this should be made mandatory so that local authorities can implement AM as a&#xa0;cross-sectoral public health approach.</p>
