Book excerpt: Available online: https://pub.norden.org/nord2022-018/ This policy brief is issued by the Nordic Working Group for Sustainable Cities, under the umbrella of the Nordic Council of Ministers. The overall objective and purpose of the efforts of this working group, which ended its work at the end of 2021 and was subsequently integrated into the Nordic Working Group on Biodiversity, was to contribute to achieving the sustainable development goals of Agenda 2030 with an emphasis on strengthening the exchange of experiences and co-operating on Nordic solutions for sustainable urban development. The importance of urban green spaces in achieving this has been a key focus of the group’s work. The text was prepared by Cecil C. Konijnendijk under assignment from the Working Group.
