Erssons
The Erssons are a family in Portland that has gone the extra mile in working to reduce their footprint and follow a sustainable lifestyle in an urban setting. (Though not what you might traditionally called an "organization", they have been categorized as an organization here at Appropedia. Why not: they are a group organized as a family...) Ole Ersson has written numerous web articles, most of which have been ported to Appropedia. The ported articles are linked at the bottom of this page.
