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.

We Operate On Indigenous Land

We acknowledge that we are on unceded Indigenous land belonging to the Coast Salish peoples. Click here to make a contribution to the Duwamish Peoples, a Tribe on whose land Seattle sits, and who remains unrecognized by the United States government. 

In addition to this acknowledgment, we own that we have much to do in learning, understanding, & carrying out the original instructions cultivated by Coast Salish nations and peoples who governed this land sustainably for more than twelve thousand years and who continue to model and advocate for sustainable practices today. These nations include, but are not limited to: the Duwamish, Suquamish, Nisqually, Snoqualmie, Muckleshoot, Yakama, and Lummi tribes and nations. Learn more about the First Nations of the Coast Salish area.

We are young in this process as an organization and as individuals. We acknowledge the complex, contested, and unjust history of both occupation and governance in this region. We also want to bring gratitude and thanks to those reading these words who are the descendents of a Coast Salish nation. We humbly seek to align with you in the stewardship of your land.

We also want to express acknowledgement that many complex personal pathways bring people to this region, including people who are indigenous to other lands. We invite all who engage with Sustainable Seattle, especially those who benefit from power and rank privilege, to hold awareness of your role and to be intentional in distributing space and power. We express gratitude for being in this space, on this land, and sharing time and space with you today.
