The Strategy "Urban Nature in Copenhagen" (2015 - 2025) aims to ensure that the Danish capital develops into a green and climate-friendly city through two primary goals: (1) to create more urban nature in Copenhagen and (2) to improve the quality of the urban nature in the city. The strategy outlines 30 measures to contribute to these aims, including: an action plan for planting an additional 100,000 trees in the city, creating a catalogue of urban nature-based solutions, and establishing an Urban Nature Fund and building partnerships with various actors in the city. The strategy applies to all urban nature in Copenhagen on municipal as well as non-municipal land. The strategy builds upon and improves the ambition of a 2009 strategy "A green Copenhagen" and has been developed in cooperation with a variety of internal and external stakeholders. The strategy has resulted in the creation of a a Green Planning Tool and a Tree policy, among other outcomes.
