由于内部的复杂性，气候变化及其影响不可能一劳永逸地解决。一些已实施的战略可能只能处理一系列问题，而对许多其他问题置之不理。然而，共同利益方法通过同时实现多个目标打开了“机会之窗”。在此基础上，本文旨在揭示城市热岛（UHI）问题与中国正在进行的海绵城市（SPC）项目之间的相互关系。具体而言，从技术、财政、体制和社会角度调查了共同效益，然后提出了实施途径。在这些方面，共同效益的方法可以为实施SPC和城市热岛缓解带来机会。将城市热岛缓解纳入SPC建设可以提高公众参与，从而巩固公私合作的资金模式。在实施共同效益方法的过程中，可以重新平衡不同当局的权重，以促进体制转型。SPC衍生的城市热岛效应减缓方法，可实现城市洪涝与城市热岛效应减缓的协同效应，可为已发布低影响开发水管理实践的国家提供示范，也可为其他城市热岛效应减缓项目如绿色建筑、低碳生态城市、智慧城市、森林城市、雾霾治理等提供借鉴。
Climate change and its impacts cannot be addressed once for all due to internal complexity. Some implemented strategies may only be capable of dealing with a cluster of problems while leaving many others untouched. The co-benefits approach, however, opens up a 'window of opportunity' via achieving multi-goals simultaneously. Based on this, this paper aims to unpack the interrelationship between the struggling urban heat island (UHI) issue and the already ongoing sponge city (SPC) projects in China. Specifically, the co-benefits are investigated from technical, financial, institutional and social perspectives, after which pathways to implementation are presented. In these aspects, the co-benefits approach can bring opportunities for implementing SPC and UHI mitigation. The inclusion of UHI mitigation into SPC construction can enhance public participation and thereby consolidate the public-private partnership model for funds. During the co-benefits approach implementation, the weights of different authorities can be rebalanced to promote institutional transitions. SPC-derived UHI mitigation approach, potentially realising synergies of urban flooding and UHI mitigation, can be a model for countries which have already released low-impact development water management practices, and may also provide references for other projects such as green building, low-carbon eco-city, smart city, forest city and haze treatment for UHI mitigation.
