Green Seal reviews most standards every three to five years. In some cases, standards require updates in order to account for changes in the market and the commercialization of new technologies. Green Seal may also conduct more focused revisions to resolve minor issues in the standards. Examples include expanding the scope, updating lists of prohibited substances, resolving difficulties, or clarifying requirements. All revisions include a public comment period during which Green Seal solicits comments related only to the proposed changes.
