The 3+30+300-Rule for Australia

Measure and Manage Urban Greening

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 is Australia?

Can you see three trees from your window? Does your neighborhood have 30% tree canopy cover? Are you within 300 meters of a green space? We have conducted the analysis for every property in Australia. We have data for the entire country but also offer specific cities.

Our analysis provides the data-driven insights needed to make cities greener, healthier, and more climate-resilient.

The 3+30+300-Rule explained

3 trees visible from any building

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.

30% tree canopy cover

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.

300 meters to the nearest park

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

Onze visie is om wereldleider te zijn in het in kaart brengen van stedelijke natuur en het geven van inzicht in de toekomstige leefomgeving.

Ik heb de 3+30+300-regel voor heel Nederland berekend. Dit geeft ongelofelijk veel informatie en sturingsmogelijkheden om te vergroenen. Bijzonder vind ik ook dat er zo'n directe link is gevonden tussen de regel en de gezondheid van mensen. Sturen op de regel is dus kiezen voor de gezondheid van je inwoners.
