Our Team

SustainUS is run by a group of volunteers elected annually by SustainUS members, which implements the organization’s campaigns. This group is made up of some of the organization’s strongest leaders who are deeply committed to advancing justice and sustainability through advocacy. This leadership group is coordinated by Emma Lyu Buretta, our Lead Coordinator. 

SustainUS is overseen by a volunteer Board of Directors, composed of both SustainUS alumni and non-alumni.
