- The 3-30-300 test is a simple urban standard to ensure equal access to nature: every home, school, and office should see at least three trees from windows, have 30% neighborhood tree cover, and be within 300 meters of a park.
- Studies reveal low compliance: only about half of Europeans have a view of three trees, one-third live in areas with 30% tree cover, and nearly 60% are within 300 meters of a park; just 14% meet all three criteria.
- Globally, among eight major cities, only Singapore passes the 3-30-300 test, highlighting widespread urban deficiencies in tree and park accessibility.
- Meeting the rule has measurable health benefits, including better mental health and reduced heat-related deaths, yet many cities, especially in southern Europe, struggle to achieve it.
- Implementation calls for actionable steps like planting more trees and removing asphalt, emphasizing that these standards should be minimums, not aspirations, to address inequities in green space access.
