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Please note: The ISEAL Assurance Code is no longer in effect. 

The ISEAL Assurance Code has been superseded by the ISEAL Code of Good Practice for Sustainability Systems (‘the ISEAL Code’) which came into effect on 1 March 2024. The ISEAL Code is the result of revising and integrating the Standard-Setting, Impacts and Assurance Codes of Good Practice, and inclusion of essential practices from the ISEAL Sustainability Claims Good Practice Guide.
