Enhancing the SASB Standards (Agenda Paper 6)

The ISSB met on 29 October 2026 to discuss the relationship between the SASB Standards and IFRS Sustainability Disclosure Standards, in response to stakeholder feedback from consultations on proposed amendments to the SASB Standards in 2025 and 2026.

The ISSB tentatively decided:

  1. to include an explanation in the SASB Standards that the requirements in IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information apply when an entity uses the SASB Standards to prepare disclosures in accordance with IFRS Sustainability Disclosure Standards.

    All 10 ISSB members agreed with this decision.

  2. to make the reliefs described in paragraph 73 of IFRS S1 available to entities using the SASB Standards to prepare disclosures in accordance with IFRS Sustainability Disclosure Standards. Specifically, as described in paragraph 73 and set out in Appendix B of IFRS S1, an entity is relieved from disclosing information that law or regulation prohibits it from disclosing, or from disclosing information about a sustainability-related opportunity that is commercially sensitive, subject to conditions specified in IFRS S1.

    Nine of 10 ISSB members agreed with this decision.

  3. to specify that the proportionality mechanism of using ‘all reasonable and supportable information that is available to the entity at the reporting date without undue cost or effort’ is available to an entity when applying the SASB Standards to prepare disclosures in accordance with IFRS Sustainability Disclosure Standards.

    Nine of 10 ISSB members agreed with this decision.

The ISSB members discussed whether and how to revise the name of the SASB Standards to enhance clarity of their status and intended function when they are used to prepare disclosures in accordance with IFRS Sustainability Disclosure Standards.

The ISSB was not asked to make a decision on this matter.  

Next steps

The ISSB will continue its deliberations on the project on enhancing the SASB Standards, including:

  1. whether an additional proportionality mechanism related to using an approach that is commensurate with an entity’s circumstances, including the skills, capabilities and resources available to the entity, should be introduced for particular SASB metrics; and
  2. whether similar measures as those discussed at the October 2026 ISSB meeting should apply when the SASB Standards are being used on a stand-alone basis without the IFRS Sustainability Disclosure Standards.
