Green Collar Technologies is a tax-exempt, 501c3 non-profit corporation registered to do business in Hawaii. 


We envision more people learning sustainability practices, being happier, healthier and more self-sufficient as a result.


  • Raise our awareness, educate ourselves and consistently improve our efforts.
  • Help raise awareness for those without a voice.
  • Provide affordable programs to help anyone learn how to live more sustainably.

We’ve raised awareness through events like the two Hawaii Island Sustainability Forums, two Hawaii Cannabis Expos and four TEDxHilo Talks. We’ve served diverse populations through our sustainable education series of classes. Tuitions remain low and our classes are often filled. We’re committed to making a difference in local communities.

In 2022, we’re building more partnerships with sponsors and donors. If you would like to get involved, please send us a note with your needs or make a quick donation to support our ongoing programs.

For a limited time we are seeking new board members to strengthen our sustainable healthcare program titled, “Hawaii Patients Union”. Details are contained in the slideshow below. Feel free to share with your colleagues capable of helping the Hawaii Patients Union grow on every island.
