The 3+30+300 Rule, developed by Dutch professor Dr. Cecil Konijnendijk, is the global standard for urban greening. This rule helps cities plan for better health, climate adaptation, and biodiversity. By understanding how neighborhoods and buildings score, cities can set priorities and green effectively. These scores also spark discussions with policymakers, residents, and businesses about where greening is most needed.
How Green Are the Nordic Countries?
Our analysis of the Nordic provides a crystal-clear picture. About 66% of the buildings in the Nordic region adhere all three rules at the same time. And 87% reaches a positive overall score. With planting trees at the right spot this number could reach 91%!
Our analysis provides the data-driven insights needed to make cities greener, healthier, and more climate-resilient.
Everyone should be able to see at least three large trees from their home, workplace, or school. Our data pinpoints where this is already achieved and where the biggest opportunities lie.
A healthy, climate-resilient city should have at least 30% tree canopy cover per neighborhood. We calculate the tree canopy cover for each home and aggregate the results to highlight areas for improvement.
No one should live more than 300 meters from a publicly accessible, high-quality green space. We identify which cities meet this benchmark and where urgent greening efforts are needed
