The Cascadia Green Building Council is a 501(c) (3) non-profit in the US and is incorporated as a nonprofit in British Columbia. Cascadia’s mission is to lead a transformation towards a built environment that is socially just, culturally rich and ecologically restorative. Cascadia is one of three original chapters of the US Green Building Council and, as a chapter of the Canada Green Building Council as well, is the only international chapter in North America. It is the originator of the Living Building Challenge, authored by Jason F. McLennan.

Cascadia Green Building Council is one of three original chapters of the U.S. Green Building Council and, as a chapter of the Canada Green Building Council as well, is the only international chapter in North America. Incorporated in Oregon in December 1999, the chapter covers Oregon, Washington,  British Columbia  and Alaska, but also includes members from as far away as Idaho and Montana. Cascadia continues to serve its members by helping the U.S. and Canada Green Building Councils meet their goals in the Pacific Northwest. We strive to become a leading force in green building by forging alliances with organizations that have a stake in the future of this region.

The chapter is named for the Cascadia bioregion, which covers land that drains to the Pacific Ocean through the greatest temperate rain forests on the planet. Members of the Cascadia council are leading the way in creating a roadmap for sustainable building, one that the rest of the nation can use as well.
