Tribal Solid Waste Advisory Network

💚 Thank You to all Our 2025 Tribal Green Summit Sponsors!

We’re grateful to the incredible sponsors who made the 2025 Tribal Green Summit possible. Hosted in partnership with the Snoqualmie Tribe, this year’s event marked 25 years of TSWAN’s commitment to tribal environmental leadership. The summit was proudly supported by the Confederated Tribes of the Colville Reservation, the Snoqualmie Indian Tribe, the Coeur d'Alene Tribe, Cascadia Consulting Group, Circular Action Alliance, Engineered Compost Systems, and funding provided through the U.S. Environmental Protection Agency (EPA). Explore highlights from the summit and see how your support helped shape a powerful gathering for sustainability and community resilience.
