See Whats Inside

Three chapters plus a governance checklist and review process

The pack works through the governance pillar in three short chapters, then shows how a Trace review turns your existing documents into an AASB S2-aligned disclosure. It covers disclosure requirements, evidence and next steps.

What your board must disclose

AASB S2 asks you to name the body responsible for climate oversight and show how that oversight works. You learn how it sits in the mandate, how the board keeps the right skills, and why disclosure is process evidenced, not intent stated.

The evidence auditors look for

Assurance providers cannot rely on a process they cannot see. The pack lists the consistent file to build, from a charter naming climate as a board responsibility to a sign-off calendar, and explains why governing in practice is not the test.

Closing the gap before your first report

A step-by-step path for boards with nothing formal in place. Fix ownership first, then update charters, set information cadence and document sign-off. Each step produces an artefact, and those artefacts are the disclosure.

The governance checklist and review process

An illustrative extract maps AASB S2 governance clauses to what to prepare and how critical each is. You also see how a focused Trace review aligns your documents to specific S2 clauses and flags gaps, without rebuilding your systems.

Key Findings

Four things boards keep getting wrong on governance

These come up repeatedly across board and finance conversations. They are not spelled out in the standard guidance, but they decide whether your governance disclosure holds up under assurance.

Governing well is not the same as evidencing it

Most boards oversee risk competently, but cannot show where climate sits. As one Audit and Risk Committee Chair put it, the problem was that no one could point to it. Auditors test documented process, not intent, so undocumented good governance still fails.

Climate ownership falls through the middle

Responsibility often sits between sustainability, finance and the board, so nobody truly owns it. The fix is to name accountability explicitly and write it into terms of reference, at both board and management level, before anything else.

Governance artefacts cannot be backdated

Charters, skills matrices and reporting logs take months to build and cannot be created retrospectively. Starting early is the cheapest path. Leaving governance until last, as most boards do, is what turns it into a scramble before the first report.

The approach you choose drives the cost

Treasury estimates ASRS preparation at $750k to $1.6m under a consultancy-led approach. A structured, software-supported process makes it repeatable instead: SEE Group cut its climate risk assessment from 13 weeks to 2.

Who This Is For

Written for the people
making ASRS decisions

This ebook is written at CFO grade, with enough detail to be genuinely useful to sustainability leads and risk teams. Not a primer. Not a sales deck.

CFOs & Finance Directors

Responsible for signing off on the disclosure. Needs to understand what auditors will scrutinise in year two, and where the financial integration gaps are in first-round disclosures.

Sustainability Managers & ESG Leads

Building the disclosure internally. Needs to understand what peers are doing on Scope 3, scenario analysis and materiality so the internal benchmark is calibrated correctly.

Risk & Compliance Teams

Needs to understand where governance documentation is falling short in first-round disclosures and what auditors are already flagging as areas for year-two improvement.

Board Members & Audit Committee

Accountable for climate risk oversight under AASB S2. Needs a clear picture of what comparable entities are disclosing and what the governance standard looks like in practice.

This ebook is particularly relevant if:

Your entity is likely to fall under ASRS Group 1, 2 or 3 (or you're not yet sure which group applies)

Your board or audit committee has asked about climate disclosure obligations for the first time

You're preparing a Group 2 first disclosure and want to learn from what Group 1 entities got right and wrong

You need to brief internal stakeholders on what AASB S2 actually requires versus what others are choosing to include

Questions we hear most from ASRS teams

These are the questions Traces team hears most often from CFOs and sustainability leads starting their ASRS journey. The full ebook answers all of them in depth.

What does AASB S2 require boards to disclose about climate governance?
AASB S2 requires you to disclose the body or individuals responsible for overseeing climate-related risks and opportunities, and how that oversight actually works. That means how climate sits in their mandate, how the board maintains the right skills, how often it is informed, how it factors climate into strategy and major decisions, and how it oversees targets and any link to remuneration. The test is process, evidenced, not intent stated. Disclosure describes what your board demonstrably does, backed by documentation an auditor can review.
Should climate oversight sit with the full board or a committee?
Either works under AASB S2. You can assign climate oversight to the full board, the audit and risk committee, or an equivalent body. The standard does not mandate a particular structure. What matters is that the responsibility is named explicitly and written into that body's terms of reference, so there is no ambiguity about who is accountable. Choose the option that fits how your board already governs material risks, then document it clearly rather than leaving it implied across several groups.
What evidence does an assurance provider want to see for climate governance?
Assurance providers want a consistent file they can review, because they cannot rely on a process they cannot see. Build a charter naming climate as a board responsibility, a skills matrix with a plan to close gaps, an ownership map from board to management, a log of board reporting frequency and format, evidence that climate informs strategy and capital decisions, and a sign-off calendar tied to reporting deadlines. Together these artefacts show a defensible, structured approach, which is what limited assurance in the early years tests for.
We govern climate risk in practice, so why is that not enough?
Because practice is not the test. An auditor cannot rely on a process they cannot see, so governance that happens informally, without documentation, does not satisfy AASB S2. Limited assurance in the early years is forgiving in one sense: a defensible, structured approach is enough and perfection is not required. But defensible still means documented. If your board oversees climate well but cannot produce charters, records and an ownership map, the disclosure will not hold up under assurance.
Where do we start if we have nothing formal in place?
Fix ownership first, at both board and management level, so accountability is clear. Then update charters and the skills matrix, set the information cadence, map climate into your existing strategy and risk processes, and document target-setting and sign-off. Each step produces an artefact, and those artefacts are the disclosure. Treating climate like any other material financial risk works well here, because boards already know how to do that. The point is to generate a defensible paper trail, not to build a parallel governance system.
How long does ASRS governance preparation take and what does it cost?
Governance artefacts take months to build and cannot be backdated, so starting early is the cheapest path. Treasury estimates ASRS preparation at $750k to $1.6m under a consultancy-led approach. A structured, software-supported process makes the work repeatable and far less costly: SEE Group cut its climate risk assessment from 13 weeks to 2. The cost is driven less by the standard itself than by how you approach it, so an early, structured method beats a last-minute consultancy scramble.
