Urban tree canopy helps us stay cool as climate warms
Canopy cover, the amount of leaf surface area, drives the benefit of an urban forest. At only 20% canopy cover, Honolulu lags behind other cities and the gap is growing as our canopy is currently decreasing. Some cities that have mounted campaigns to plant trees, such as Pittsburgh, have achieved over 40% canopy cover.
Let's get Honolulu to
35% canopy cover by 2035!
What we do!
Raise public awareness about the benefits of trees
Develop curriculum for schools
Provide information to guide tree planting
Increase public and private funding of tree planting and maintenance
Identify neighborhoods with the lowest canopy cover and coordinate efforts between government, private and community groups to plan, find resources and plant!

What trees do!

Honolulu receives a 300% return for investing in tree care!
