Preparing Your Board for Its First AASB S2 Disclosure: A Practical Checklist

Of the four core content areas in AASB S2, Governance is usually the one boards assume will be the easiest to address. Many boards already discuss climate informally, receive occasional briefings, and feel broadly across the issue. The gap between that informal awareness and what AASB S2 actually requires to be disclosed, in writing, with specifics, is where most first time reporters run into trouble. Here is a practical checklist to work through before your first reporting period locks in the answer.

1. Name the responsible body, formally

AASB S2 requires an entity to identify the specific governance body, committee, or individual responsible for oversight of climate related risks and opportunities. If that responsibility currently sits informally with “the board” as a whole, decide now whether it should be formalised with a specific committee (audit and risk, sustainability, or a dedicated climate committee) or retained at full board level, and document that decision.

2. Update the terms of reference

Once the responsible body is identified, its terms of reference, charter, or mandate needs to actually reflect climate oversight as a defined responsibility, not something addressed as a standing agenda afterthought. Disclosure requires an explanation of how responsibility for climate is reflected in these governing documents, so if the paperwork does not currently say it, this is the first practical fix.

3. Assess the skills gap honestly

The standard asks how the responsible body determines whether it has appropriate skills and competencies to oversee climate related strategy, and if not, how it plans to develop them. This means a genuine skills assessment against the board’s actual climate exposure, followed by a documented plan, whether that is external training, co-opting expertise, or bringing in specialist advisers for specific decisions.

4. Set (and follow) an information cadence

Disclosure requires stating how, and how often, the responsible body is informed about climate related risks and opportunities. An ad hoc briefing whenever something comes up will not satisfy this well. Set a deliberate cadence, whether quarterly board papers, an annual deep dive, or both, and keep records that show it actually happened.

5. Show climate feeding into real decisions

This is where many boards fall short in substance rather than process. AASB S2 wants evidence that climate related risks and opportunities are taken into account when the board oversees strategy, decides on major transactions, and manages risk, including whether trade offs between climate factors were actually considered. A capital expenditure paper or acquisition decision that never mentions climate exposure, when the entity has identified material climate risk elsewhere in its disclosure, is a consistency problem waiting to be noticed.

6. Oversee target setting and track progress

If your organisation has, or plans to set, climate related targets, the board’s oversight of that target setting process, and how it monitors progress against those targets, needs to be disclosed specifically. This includes whether performance against climate metrics is factored into remuneration policy, and if so, how.

7. Clarify management’s delegated role

Governance disclosure is not only about the board. AASB S2 also requires an explanation of management’s role: whether oversight is delegated to a specific position or management level committee, how the board oversees that delegation, and whether the controls and procedures management uses are integrated with the organisation’s other internal functions, rather than run as a standalone climate process disconnected from everyday operations.

8. Start documenting now, not at reporting time

Every item above needs to be described in the disclosure itself, which means the underlying governance activity needs to be actually happening and recorded well before the reporting period closes. A board that does the right things in the final quarter before its first report is due will have very little evidence to draw on. Minutes, papers, and terms of reference updated today are what make an accurate, defensible governance disclosure possible next year.

9. Work backwards from your first reporting date

Once you know which AASB S2 group your organisation falls into, map these nine items against your actual first reporting period and identify realistic timing for each. Governance maturity, more than any other pillar, tends to take the longest to build credibly, simply because it depends on a pattern of board behaviour over time rather than a single piece of analysis.
