This page shows past exhibits at our old site in San Francisco’s Mission District.  We leased this site for 3 years and then moved our charity out of this space and into 2 new ones.

For our new sites and exhibits please check out our Eco-Industrial Hub and our Model Eco-Home



The following Eco Center Exhibits provided information on Matter of Trust projects and can broadly be divided into three areas:

  1.  Surplus and Needs

Programs balancing surplus with needs

  1.  Naturally Abundant Renewable Resources

Programs celebrating how nature is abundant and always in balance

  1. Eco-educational programs at the Eco-Center:

Informational – Visitors that come in on average 15 minutes or less (browse the gift shop, tour the exhibits, grab our flyers or partner pamphlets) eco-influence is varied and harder to trace.

Educational – Stays over an hour during a field trip, class, lecture, panel, roundtable, B’Earthday party… provide participants with eco-literacy terms and being able to describe these programs and goals in your own words.

Transformational – inspirational eco-education (through programs, projects, summer camps, courses, green jobs, campaigns, mobilizations…) that promotes:

– small, personal eco-habit changes that accumulate over a lifetime

– trend setters to be eco-examples that ultimately create societal shift
