Proposed International Standard on Sustainability Assurance (ISSA) 5000 – General Requirements for Sustainability Assurance Engagements

The proposed ISSA 5000 is designed to be a comprehensive and independent standard applicable to limited and reasonable sustainability assurance engagements. The proposal is more specific than ISAE 3000 (Revised) and ISAE 3410 for sustainability priority areas. It will cover sustainability information reported on various topics and prepared under multiple frameworks, including the IFRS Sustainability Disclosure Standards S1 and S2.

The anticipated approval of the standard is expected to be before the end of 2024.
