The ISSB held a supplementary meeting on 4 April 2023. The following item was discussed:

General Sustainability-related Disclosures: The ISSB decided to grant an optional relief that allows companies applying the ISSB Standards to phase in their approach to sustainability-related disclosure, beginning with climate-related risks and opportunities in the first year of reporting. For companies using the proposed relief, the full reporting on sustainability-related risks and opportunities (beyond just climate) would be provided from the second year. The ISSB also tentatively decided that if an entity uses this transition relief, it would be required to disclose that fact, and could extend the previously agreed transition relief in IFRS S1 related to disclosing comparative information such that the entity would not be required to disclose comparative information related to its other sustainability-related financial information in the first year it discloses that information.
