We plant trees where they offer more direct benefits for people.


No politics— everyone wins when we plant trees!

Our Approach

Planting trees along highways and other large roadways is linked with reductions in air pollution*.

Green Interchange was the idea of Congressman Mark Green, whose love of the outdoors motivates him to protect and beautify our environment.  Our mission is to plant trees and establish and sustain natural systems for healthier communities, economies, and quality of life.


How We Work


Simple and Effective. 

We plant trees where they have maximum impact along  roadways, waterways, and in "other ways" such as public spaces or other places.  Trees and other natural infrastructure offer outstanding benefits, for instance:  

"Noise and vegetative barriers can reduce downwind pollutant concentrations near roads."  

- U.S. Environmental Protection Agency (EPA) 

"Forested stream banks act like a sponge, filtering out excessive nutrients, sediment, and other pollutants that run off from the land that would be damaging if they entered a stream. "

- Christina Catanese , The EPA Blog
