🌳 Global Cities Failing the 3-30-300 Urban Nature Benchmark

A new study applied the 3-30-300 rule — a simple but powerful standard for urban green space — to 2.5 million buildings across 8 major cities: New York, Seattle, Singapore, Amsterdam, Buenos Aires, Denver, Melbourne & Sydney.

The rule:
✅ See 3 trees from home/school/work
✅ Live in a neighborhood with 30% tree canopy
✅ Be within 300m of a park

🔍 Findings:
👉Most buildings fail, especially on the 30% canopy target.
👉Tree views are common, but actual canopy cover is too low — trees are too small or too sparse.
👉Proximity to parks varies, and achieving one part doesn’t guarantee the others.

📉 The results reveal critical deficits in local nature access, even in "green" cities.

🌱 Why it matters:
The 3-30-300 rule helps cities focus on local, meaningful green exposure — key for mental health, climate resilience, and equity.
🛠 Cities must invest in better tree planting, growth conditions & smarter governance to truly green our neighborhoods.
