Honor Earth Day,
Every Day.

Our mission

Promote and advocate for livable and sustainable principles and practices, bringing stakeholders together to create and maintain a community-wide collaborative effort, improving quality of life for all residents, and building resilience in the Tri-Cities region.

The ALSC acknowledges that the Tri-Cities region is on the traditional homeland of the Nez Perce, Umatilla and Yakama peoples.

What unites us is the vision of Sustainability. Simply put, if you like something, you should use and care for it so that your kids and their kids can enjoy it too.
