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.
🌳 3 trees visible from every home
🌳 30% tree canopy in every neighborhood
🌳 300 meters to the nearest public green space
Widely adopted across Europe, this approach provides a new, actionable lens for tree equity and urban greening in North America.
