Given the state of the climate emergency, European Union (EU) cities must find innovative ways to achieve a sustainable and decarbonised urban mobility trajectory. This requires integrated and cross-sectoral approaches that enable all sectors influencing such mobility to contribute to this goal. Building on the concept of the climate-connected city and drawing on an extensive empirical investigation of two Dutch cities (Rotterdam and Maastricht), this study reflects on how decarbonisation targets are integrated with other sustainability objectives across all policies and levels involved in reconfiguring mobility towards an environmentally sustainable model. The study finds that spatial development tools and processes, in combination with regulatory instruments imposing strict limits on emissions, can strengthen cross-sectoral support for the behavioural changes needed to decarbonise urban mobility. However, this integrative dynamic may be countered by local economic actors and by national and EU economic and fiscal instruments, whose narrow focus on reducing vehicle emissions and expanding road capacity forces cities to dilute their sustainable mobility policies. This suggests that in order to accelerate the decarbonisation of urban mobility, these instruments should be aligned with a broader set of sustainability goals and solutions and be combined with greater attention being given to the urban dimension into national and European transport policies.

鉴于气候紧急状态，欧盟 (EU) 城市必须找到创新方法来实现可持续和脱碳的城市交通轨迹。这需要采取综合和跨部门的方法，使影响这种流动性的所有部门都能为这一目标做出贡献。本研究以气候相关城市的概念为基础，并借鉴对荷兰两个城市（鹿特丹和马斯特里赫特）的广泛实证调查，反思了如何将脱碳目标与涉及重新配置流动性的所有政策和层面的其他可持续发展目标相结合，以实现可持续发展。环境可持续的模式。研究发现，空间开发工具和流程与严格限制排放的监管工具相结合，可以加强对城市交通脱碳所需的行为改变的跨部门支持。然而，这种一体化动力可能会受到当地经济参与者以及国家和欧盟经济和财政工具的抵制，这些工具狭隘地关注减少车辆排放和扩大道路通行能力，迫使城市淡化其可持续交通政策。这表明，为了加速城市交通的脱碳，这些工具应与更广泛的可持续发展目标和解决方案相结合，并与国家和欧洲交通政策对城市层面的更多关注相结合。
