Abstract: Climate change has become a key challenge for sustainable urban development. To approach this issue, ecosystem-based adaptation (EbA), i.e., the management of ecosystem services for climate change adaptation, has been promoted as a cost-effective and sustainable approach to improving adaptive capacity by increasing scholars and practitioners. However, little information is available on the actual inclusion of EbA measures in urban climate change adaptation plans at the multiple-scale level with cooperation from various stakeholders. Through qualitative methods, this paper addressed this gap and analyzed how EbA is included in climate change adaption plans and how EbA is implemented on multiple scales in Copenhagen, one of the well-known European green capitals for local climate change adaption practices. We reviewed the development of EbA and its implementation in Europe, investigated the Copenhagen climate change adaptation plans and policies and the cooperative application of EbA at the municipal, community, and individual building scales, and utilized the case study of Copenhagen's first climate-resilient community to demonstrate how EbA measures could be implemented to local climate change adaption cities through multi-stakeholder planning by governments, businesses, people, and other place based stakeholders. We closed this paper with a summary of experiences learned from the implementation of EbA measures in multiple-scale climate change adaptation cooperative planning in Copenhagen: 1) Pre-project data preparation and analysis in depth; 2) close Integration of EbA measures with the landscape design of urban spaces; and 3) coordinating with multiple stakeholders and promoting public participation. This study enhanced the understanding of EbA implementation for climate change adaption city building and could inspire future initiatives in other cities, including cities facing climate challenges in China.
