ACCA welcomes the strengthening of corporate reporting on sustainability with the publication of the first two standards from the International Sustainability Standards Board (ISSB): IFRS S1, General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2, Climate-related Disclosures. As part of support to members on this important development, we've partnered with the ISSB to produce a series of videos.

ACCA has also distilled the key disclosure requirements of IFRS S1 and IFRS S2 into worksheets that accompany the guidance to produce sustainability information. These worksheets not only support a high-level understanding of the key reporting requirements but can also be used to collect or communicate the required data.
