We are a non-profit 501(c)(3) organization based in Seattle.  Our mission is to bring the wide range of environmental benefits of trees to our cities and towns in America.  We seek to make American cities greener and healthier by enabling urban tree-planting and preservation projects to earn carbon credits to generate much-needed funding for our declining urban forests.  

We are supported by generous grants from:

  • The Bullitt Foundation
  • Herman P. and Sophia Taubman Foundation
  • Laird Norton Family Foundation
  • McKibben Merner Family Fund
  • DragonFly Fund
  • Beardsley Family Foundation
