AASB S2 is where climate disclosure meets audit reality.
One of the most significant shifts under AASB S2 isn’t just the requirement to disclose climate-related risks and opportunities, it’s the expectation that those disclosures are clearly connected to the financial statements and capable of standing up to audit scrutiny.
Auditors are no longer looking at climate disclosures as a parallel narrative.
They are testing whether:
- The climate risks discussed in the sustainability statement are reflected in the numbers and assumptions used in the financial statements.
- The results of scenario analysis are either built into financial decisions, or clearly explained if they are not.
- Governance, controls, and data processes supporting climate information are robust, repeatable, and documented.
What we’re seeing in practice is that the challenge isn’t just identifying climate risk, it’s demonstrating connectivity. Where a sustainability statement describes material climate impacts, auditors will expect to see evidence of how those impacts have been considered in:
- Financial planning
- Budgets
- Forecasts
Under AASB S2, inconsistencies between climate disclosures and the financial statements are likely to be challenged. Statements such as “no material financial impact identified” now require a defensible explanation, aligned assumptions, and a clear audit trail.
For organisations in the first wave of disclosures, AASB S2 is setting a new bar: climate information must be decision-useful, internally consistent, and audit-ready. Achieving this requires early and ongoing collaboration between sustainability, finance, risk, and audit teams.
Climate risk is business risk, and auditors are treating it that way.
