The Cascadia Region Green Building Council is the premier green building organization in the Pacific Northwest concerned with making change in the built environment for positive environmental impact. As a cross-border advocacy organization we bring a unique perspective to green building by taking a bioregional approach to problem solving.  We endeavor to make significant change out of all proportion to our size, by acting as a lever for organizations in both the private and public sectors through creative programs, events and tools.  Cascadia promotes the design, construction and operation of buildings in Oregon, Washington and British Columbia that are environmentally responsible, profitable and healthy places to live, work and learn.
