IFRS S2

Definition

IFRS S2 Climate-related Disclosures is the international climate disclosure standard issued by the International Sustainability Standards Board. AASB S2 is based on it with Australian modifications. An entity complying with AASB S2 is not automatically compliant with IFRS S2 and should not claim compliance with both without checking the differences.

In practice

This matters where an Australian entity has an overseas parent, overseas investors, or a listing in a jurisdiction that has adopted IFRS S2 directly. The two texts are close but not identical, and a claim of IFRS S2 compliance made in an Australian report is a statement that can be tested.

What the assurer does with it

The assurer reads the compliance statement literally. A statement of compliance with IFRS S2 is a claim about the whole standard, including the industry-based metrics requirements the Australian text deletes, so it brings work into scope that the statutory obligation does not require.

They accept a single, accurate statement of compliance with AASB S2, and a separate clearly labelled statement about group reporting under IFRS S2 where one is genuinely made. They reject a dual-compliance claim with no analysis of the differences behind it, and a basis of preparation naming IFRS S2 as the standard applied to an Australian statutory sustainability report.

Commonly confused with

AASB S2, which is the instrument the Corporations Act requires. Also confused with the assumption that group reporting under IFRS S2 satisfies the Australian obligation, which it does not on its own.
