In 2010, Copenhagen, Denmark, launched its Green Roof Policy, a forward-thinking initiative requiring new municipal buildings with roof slopes of less than 30 degrees to feature green roofs. This broad-reaching policy covers a wide range of structures, from schools and mixed-use buildings to cycle shelters and underground garages. The primary goal of this initiative is to bolster climate resilience, promote urban biodiversity, and enhance the overall well-being of Copenhagen’s citizens. The policy has been remarkably effective, leading to the creation of over 40 green roofs and covering approximately 200,000 square meters within the first two years. Spearheaded by the City of Copenhagen’s Environment and Technical Administration, this initiative stands as a testament to the city’s commitment to environmental sustainability and urban innovation.

Innovation and Impact:
Initiative stands as a pioneering approach in urban sustainability, being the first in Europe to mandate green roofs in a city’s climate plan. The innovation lies in its wide applicability across various building types and its integration with the broader Cloudburst Management Plan to address climate change challenges like increased stormwater volumes. This policy differentiates between lowmaintenance extensive roofs and recreational intensive roofs, offering a nuanced approach to urban greening. Its success has set a precedent for urban climate adaptation worldwide, combining environmental, social, health, and economic benefits in a comprehensive urban sustainability model.
