Sustainable Seattle works to build a thriving future through initiatives that deliver environmental, economic and community benefits, promote equity, and build resilience.


A thriving, regenerative, sustainable Seattle which centers reciprocity, liberation, and restored abundance.


We define sustainability as the ancient and enduring practice of creating richness in natural resources, attuning to nature’s environmental indicators, and providing equitable access to health, food, shelter, and economic wealth for all people.

Land Acknowledgement

We would like to acknowledge that our work takes place on the traditional land of the first people of Seattle, the Duwamish People, past and present, and honor with gratitude the land itself and the Duwamish Tribe.

Sustainable Seattle encourages attendees of our events to support Duwamish Tribal Services by paying real rent to Real Rent Duwamish.
