The growing impacts of climate change are urging effective countermeasures in terms of adaptation, particularly through appropriate policy tools integrated across levels of governance. Local governments, often at the forefront of climate action, play a critical role. The regional level can become a key element in the adaptation chain, connecting higher‐level perspectives to local implementation. The present study aimed to investigate, first, the formal development of regional adaptation policies and, second, their potential to drive local change, focusing on the case study of Italian regions. This study proposed a twofold, qualitative‐quantitative assessment methodology based on the European Regional Adaptation Support Tool framework and a novel approach built on six main factors. Our analysis revealed the underdevelopment of regional adaptation policies, highlighting a critical interruption in the adaptation chain interconnecting European, national and local levels. Furthermore, even when formally issued, regional policies exhibited several significant weaknesses, severely hampering their potential to foster local change. This was especially evident in the generally limited efforts to engage internal and external climate agents through structured mechanisms. In this context, it would be beneficial for regions to embrace the role of coordinating local efforts and actions. Providing actionable solutions, along with related monitoring and evaluation tools, could enhance local climate action and inform the revision of policies across governance levels. Adaptation policies should envisage actions that progressively involve and promote change comprehensively across the territory. We conclude that further efforts should focus on strengthening local climate resilience, not only by developing formal adaptation policies but also by fostering local change.
