Cities are emerging as leading forces for climate change adaptation and resilience. Many approaches and tools have been developed and used to measure climate resilience in cities. In this study, we explore if and how such tools can be or have been used to support decision-making for building urban climate resilience. We applied a deep analysis of 27 tools developed for measuring urban climate resilience and supplemented it with semi-structured interviews with experts who implemented such tools in over 100 cities around the world. Our analysis shows that only about one-third of these tools are designed to support implementing resilience actions while the rest mainly focus on sharing knowledge and raising awareness. We also observed a prevailing focus on evaluating coping and incremental adaptation capacities (as opposed to transformative capacities) against climate risks in such tools, which tends to trigger short-term fix rather than long-term solutions. Therefore, we argue that urban climate resilience measurement tools need to 1) support action implementation processes as much as assessing outcomes, and 2) consider the enabling environment for enhancing transformative capacities as much as coping and incremental adaptation capacities of cities. Finally, we explore challenges and opportunities of implementing resilience actions drawn from end-users' insights.

城市正在成为气候变化适应和复原力的主导力量。已经开发并使用了许多方法和工具来衡量城市的气候适应能力。在这项研究中，我们探讨了这些工具是否以及如何可以或已经被用于支持决策建设城市气候适应能力。我们对 27 种用于衡量城市气候弹性的工具进行了深入分析，并通过对在全球 100 多个城市实施此类工具的专家的半结构化访谈进行了补充。我们的分析表明，这些工具中只有约三分之一旨在支持实施复原力行动，而其余工具主要侧重于共享知识和提高意识。我们还观察到，人们普遍关注评估此类工具中针对气候风险的应对和增量适应能力（而不是变革能力），这往往会触发短期修复而不是长期解决方案。因此，我们认为城市气候适应力测量工具需要 1) 支持行动实施过程以及评估结果，2) 考虑增强转型能力的有利环境，以及城市的应对和增量适应能力。最后，我们探讨了根据最终用户的见解实施弹性行动的挑战和机遇。
