The International Auditing and Assurance Standards Boards (IAASB) has approved the withdrawal of International Standard on Assurance Engagements (ISAE) 3410, Assurance Engagements on Greenhouse Gas Statements.
This decision follows the issuance of the International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements. ISSA 5000 addresses assurance of all types of sustainability information, including greenhouse gas emissions, regardless of how that information is presented. It is effective for assurance engagements on sustainability information reported for periods beginning on or after 15 December 2026, or as at a specific date on or after 15 December 2026.
Consequently, the withdrawal of ISAE 3410 will take effect from the effective date of ISSA 5000.
ISCA will be adopting the Singapore equivalent of ISSA 5000 – the Singapore Standard on Sustainability Assurance (SSSA) 5000. The effective date of SSSA 5000 is expected to be aligned to ISSA 5000. Similarly, SSAE 3410 will be withdrawn as of the effective date of SSSA 5000.
