The Membership Committee is a permanent committee of the ISEAL Board of Directors that is responsible primarily for forming recommendations on new membership applications, deciding on member disputes that may arise as a result of an independent evaluation of Code Compliance, and deciding on appeals decisions of the Secretariat not to recommend ISEAL Community Member status or to suspend or withdraw Code Compliant status.

The Committee brings together representatives from ISEAL Community Members who have a strong overall understanding of sustainability standards. It is composed of up to 7 individuals appointed by the ISEAL Board.
