Karen Susag, Member of the Greenaction Board of Directors

Karen rejoined Greenaction’s Board of Directors in January 2021.
Karen was a co-founder and original Board member of Greenaction when she worked with grassroots leaders from frontline urban, rural, and Indigenous communities to found our organization in late 1997.

A resident of the frontline community of Richmond, California, Karen has been a Greenaction supporter and community activist for many years. Karen says “My passion and desire for health and environmental justice are my grounding principles.”

As a cofounding Greenaction Board member, I remember the fundamental reasons for the founding of the organization. I remember the wind and the rain at Ward Valley during the occupation. I remember the sacred fire and the fundamental shift in my understanding and awareness of the stakes of environmental racism.

Karen believes it is essential for Native American tribes and frontline communities to lead the struggle for health and environmental justice, saying “Without this leadership, justice is not possible. This principle is the bedrock of Greenaction’s foundation.”

Karen worked at Greenpeace USA fundraising and working on a campaign in the early 1990s, both in Arizona and California. She then moved to the Bay Area where she focused on the link between cancer and environmental toxins and helped cofound the Toxic Links Coalition to help “Stop Cancer Where It Starts.”
