This edition of The State of Play: Sustainability Disclosure and Assurance marks six years of benchmarking data and corresponding analysis. Our findings suggest the global sustainability reporting ecosystem is becoming less fragmented as more companies begin adopting, or preparing to adopt, the International Sustainability Standards Board (ISSB) Standards and European Sustainability Reporting Standards (ESRSs).

The International Auditing and Assurance Standards Board (IAASB) has released a new Frequently Asked Questions (FAQ) publication to support implementation of the International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements.

The FAQs focus on the application of materiality in sustainability assurance engagements and are intended to promote consistent understanding and effective application of the concept under ISSA 5000.

The document explains how both reporting entities and assurance practitioners apply materiality in the context of sustainability information, including:

• Understanding the information needs of intended users of sustainability information;
• Addressing qualitative and quantitative disclosures;
• Addressing double materiality considerations, when required; and
• Considering how materiality is applied throughout the engagement to support decision-useful sustainability reporting.

The FAQs also provide explanations and illustrative examples to help stakeholders better understand the application of the concept of materiality under ISSA 5000. The new material brings together other related matters highlighted in other IAASB support materials by providing appropriate links.

The document is available on the IAASB website here: www.iaasb.org/ISSA5000

This publication complements IAASB’s existing resources and is intended to support practitioners, preparers, regulators, and other stakeholders as they implement, or prepare for the implementation of, ISSA 5000. It does not amend, override, or supersede the requirements of ISSA 5000.
