Sustainable Bellingham has built a solid infrastructure to be as effective in their community as possible. Team members Sandy Hoelterhoff, Lynnette Allen and David Kowalsky discuss their decision-making tool QET (a Quick Effective Tool), as well as a natural-systems model to define roles for producing events. Called ACORN, it includes roles based on directions of the compass (e.g., physical logistics tasks are in the south, oversight in the north). With a mission of education and communication, they network people, projects and groups with similar interests. Among Sustainable Bellingham 's activities are film showings and a Sustainable Transportation Fair. Episode 108.
