ASRS S2 requires companies to disclose how the board oversees climate-related risks and opportunities and how management assesses and manages them. Documenting governance for audit assurance means producing an evidence trail: a mandate naming the responsible body, records showing how climate information reaches the board, and documented links between board oversight and the company's strategy, targets, and remuneration. Without this evidence, genuine board engagement on climate cannot be demonstrated to an assurance provider.
Gaps in governance records are among the most common findings in first-year ASRS assurance reviews. Under limited assurance, auditors are not looking for perfection. They are looking for documentation that supports the disclosures made. A company that has been informally active on climate governance often finds the gap is not in what it does, but in what it has written down.
ASRS S2 (AASB S2) defines governance disclosure across two dimensions: the board's oversight role and management's role in assessing and managing climate-related risks and opportunities. Each sub-requirement corresponds to a specific type of evidence.
For board oversight, the standard requires disclosure of:
For management's role, the standard requires disclosure of:
Each of these sub-requirements needs a corresponding piece of evidence that an assurance provider can verify independently.
The most efficient approach is to work back from what an assurance provider will ask to see. In practice, they look for four things.
A governance mandate. This is typically a board or committee charter that explicitly names climate risk as a responsibility. The name or format of the document does not matter. What matters is that at least one governing document describes who is responsible for overseeing climate-related risks and opportunities. Without a formal mandate, there is nothing to point to when the disclosure states that the board or a specific committee has oversight.
Records of climate briefings to the board. This means board papers or committee reports that include climate content, and meeting minutes that record that climate was discussed. The frequency and format of briefings in the records should match what the disclosure states. If the disclosure says the board receives quarterly climate updates, the papers and minutes should reflect this. Briefing materials distributed but not minuted do not satisfy assurance requirements.
Evidence of climate in strategic and investment decisions. Where climate risk is material to a significant decision, that relevance should appear in the supporting documentation: the investment paper, the board memo, or the meeting minutes for the relevant decision. This does not require a separate climate section in every board paper. It requires that material climate considerations are captured in writing when they are relevant to decisions the board is making.
Skills and competency records. ASRS S2 requires disclosure of how the board maintains or plans to develop the competencies needed to oversee climate-related risks and opportunities. The most common evidence for this is a board skills matrix that includes climate or sustainability risk as a competency category, together with any records of director briefings, external speakers, or training sessions on climate topics. A skills gap and a plan to address it satisfies the requirement; a gap with no plan does not.
Management governance documentation needs a clear record of ownership and reporting lines.
The disclosure must name the position, function, or group responsible for assessing and managing climate-related risks and opportunities. This could be a named role such as Chief Sustainability Officer, a function such as the Risk and Compliance team, or a cross-functional group such as a Climate Working Group. The label matters less than the clarity and formality of the assignment.
Supporting documentation should include:
Companies that have been running informal climate programs often find that none of this documentation exists in written form. The oversight is real but undocumented. The priority in that case is to formalise what already happens rather than create new processes. A retrospective record that accurately reflects actual practice is more credible than a governance framework designed for disclosure that does not reflect how the organisation operates.

Assurance providers conducting limited assurance on ASRS governance disclosures do not simply accept management representations. They ask for documentary evidence that the described oversight processes exist and function as stated. The evidence trail needs to be traceable, consistent, and sufficient to support each assertion in the governance disclosure.
A practical way to structure this is to work through the disclosure paragraph by paragraph and ask: if an auditor challenged this statement, what document would we produce? For each statement in the governance disclosure, there should be at least one piece of contemporaneous evidence. "Contemporaneous" is important: documents created after the fact to support a disclosure carry less weight than records produced at the time the oversight activity occurred.
The most common evidence gaps that emerge during first-year assurance reviews are:
One point that frequently creates confusion: governance disclosures are not forward-looking statements and are therefore not covered by the ASRS modified liability period (which runs from 1 January 2025 to 31 December 2027). The modified liability period limits who can bring action over specific forward-looking content such as Scope 3 emissions and scenario analysis disclosures. Governance disclosures describe how the board currently oversees climate risk. They are statements of present fact, and the full liability regime applies to them from day one of mandatory reporting.
This means the governance documentation gap carries more immediate risk than the Scope 3 data gap for many organisations. Getting governance documentation right in year one is a higher priority than it might appear when reading the liability relief provisions.
The following sequence addresses the most common gaps in the order that matters most for assurance readiness.
Step 1: Map the disclosure to evidence. For each statement in the governance section of the draft disclosure, identify the document that supports it. Where no document exists, that is a gap to close.
Step 2: Amend governing documents. Update board and committee charters, Terms of Reference, and position descriptions to formally assign climate responsibilities. These amendments should be approved and minuted by the relevant body.
Step 3: Establish standing agenda items. Add a climate standing item to the relevant board or committee meeting agenda for all future meetings. Ensure the agenda item generates minuted discussion. A single meeting with a substantive climate item on the agenda produces more useful evidence than twelve meetings where climate was discussed informally but not recorded.
Step 4: Document the management reporting process. Create or update a reporting framework document that describes how climate information flows from management to the board: what is reported, by whom, how often, and in what format. This does not need to be a lengthy document. A single-page framework document, approved by management and sighted by the board, is sufficient.
Step 5: Engage the assurance provider before finalising the disclosure. Share the draft governance disclosure with the appointed assurance provider and ask them to confirm what evidence they will need for each statement. This step avoids the common pattern of completing a disclosure and then discovering mid-assurance that the supporting evidence is insufficient.
Assurance providers look for a formal mandate (board or committee charter naming climate risk), records showing climate is reported to the board at the stated frequency (board papers, committee reports, meeting minutes), evidence that climate is considered in strategic decisions, a skills matrix covering climate competency, and formal documentation of the management role responsible for climate. Each statement in the governance disclosure should be traceable to at least one contemporaneous document.
No. ASRS S2 does not prescribe which governance body oversees climate risk. The full board, the audit and risk committee, or a dedicated sustainability committee all satisfy the requirement. What matters is that the responsible body is clearly identified, that responsibility is written into its governing documents, and that meeting records show the oversight is real and regular.
For a first-year ASRS disclosure, assurance providers focus on the reporting period. Documentation from within the financial year being reported is the primary evidence base. However, if the disclosure states that governance structures have been in place since a prior period, evidence from that prior period may be requested to support the statement.
Retrospective documentation carries less assurance weight than contemporaneous records. A board minute produced six months after a meeting to record a discussion that was not captured at the time is weaker evidence than a minute produced at the time of the meeting. Where gaps exist, the better approach is to create prospective records going forward and be transparent in the disclosure about the maturity of the governance framework.
The most common gap is a mismatch between what the disclosure states and what the records show. A disclosure may state that the board receives regular climate briefings, but meeting minutes contain no record of climate discussions. Fixing this requires adding climate as a standing agenda item and ensuring minutes capture the discussion, not just that the item was on the agenda.
