SLA was chosen to facilitate a think tank consisting of experts from different fields to develop Copenhagen’s green identity and future urban nature. This development catalogue is the result of these deliberations and it explores different perspectives and existing knowledge about nature based urban development and implemented climate adaptation projects in Copenhagen. The Copenhagen Model is introduced as a concrete development tool that promotes and qualifies the decision-making process in all phases of a project, which ensures that urban nature’s potential is realized within the framework of the individual climate adaptation project.
