The ISEAL Assurance Code of Good Practice Version 2.0 was published February 2018. It provides a framework for credible assurance that is delivered consistently by sustainability standards systems, so as to improve the effectiveness of their assurance models in contributing to their intended sustainability impacts.

Please note: The ISEAL Assurance Code is no longer in effect. 

The ISEAL Code of Good Practice for Sustainability Systems (‘the ISEAL Code’) came into effect on 1 March 2024, replacing the ISEAL Impacts, Standard-Setting and Assurance Codes of Good Practice. If you have any questions, please contact compliance@isealalliance.org.
