The ‘3-30-300’ Rule

The new benchmark in green amenities distribution

It’s not just how many trees, but how we distribute our trees that makes the biggest impact. The new ‘3-30-300’ rule sets the new global benchmark for measuring equitable urban green amenities distribution in our cities.

  • The ‘3’ – 3 trees should be viewable from each house improving mental health and air quality

  • The ‘30’ –  30% tree canopy should cover each neighbourhood reducing urban heat and promote biodiversity.

  • The ‘300’ – 300 m should be the farthest walk to a park or quality green space encouraging physical activity and fostering community interaction
