Defensible and useful: making mandatory climate disclosure worth reading

Mandatory climate disclosure is good for our market, and worth saying so plainly. The worry we keep hearing is that it could harden into a defensive compliance exercise, standardised across the industry but stripped of the meaning that made it worth doing. We do not think it has to. 

With the right operations underneath it, the same disclosure can satisfy the regulator – and stay genuinely useful to the super fund in other ways, not least when it engages with its members. This is the case for how.

Start with what the regime is actually for. It is fair to ask what mandatory disclosure adds when large super funds and asset managers already price climate risk into how they invest. The answer is that AASB S2 is a financial reporting standard, not environmental policy. Its job is to put the financial risks and opportunities that climate poses to an entity in front of the people who allocate capital, in a form they can compare. That is a real gap worth closing, and every step that narrows it leaves the whole market better informed.

The familiar part of this is emissions, and years of net-zero commitments have made decarbonisation the headline. It matters, though not only as an environmental goal. Reducing emissions is also risk reduction: a portfolio carrying fewer emissions is more resilient to a rapid repricing, where emissions become expensive through policy, carbon costs or shifting demand.

But emissions are only one part of what the standard asks for. Following IFRS S2 and the TCFD framework before it, AASB S2 covers two families of risk. Transition risk, broken into policy and legal, technology, market and reputation. And physical risk, split into acute events such as storms, floods, bushfires and heatwaves, and chronic shifts such as sea-level rise, rising temperatures and water scarcity. Alongside both sit the opportunities.

Physical risk is the half that has been under-discussed, and the one moving fastest. Natural catastrophes caused around US$417 billion in economic losses globally in 2024. For an asset owner holding property, infrastructure and farmland, that is value coming straight off the portfolio when a flood, a fire or a storm reaches an asset the fund owns. None of this is about assigning blame for emissions. It is about managing risk, which has always been the core job of every tier in the chain: the company running the asset, the manager allocating to it, and the asset owner standing behind it for members. The standard does not create that job. It asks them to show how they are doing it.

Here is where the worry comes from. AASB S2 disclosures carry real liability. The existing Corporations Act and ASIC framework applies to the sustainability report, misleading and deceptive conduct included, with directors personally accountable for what it says. The regime offers a modified liability period as a transition, protecting forward-looking statements in the first year, and scope 3, scenario analysis and transition plans for the first three years. But the statements that needed protecting are the forward-looking, depth-rich ones, which tells you where the legal risk sits. 

Under that pressure, the path of least resistance is to make the disclosure defensible rather than useful, with real intent replaced by language built to survive challenge. That is how a regime designed to improve decision-useful information could, left to drift, train its producers to say less.

It does not have to drift that way, and the fix is more operational than editorial. A climate disclosure has more than one audience inside the same fund, and serving them well is a collaboration, not a competition. Finance and compliance own the financial angle, and they can meet it head on: naming the transition and physical risks and opportunities, quantifying the exposure, and standing behind the numbers under assurance. The responsible investment and stewardship teams own a different and older conversation, the one they have had with members for years: what the fund expects of the companies it owns, how it votes and engages, and how members' money is being put to work. Neither account is the lesser one. They are two true views of the same portfolio.

What lets them hold together is a single source of truth. When finance, investment, legal and compliance, and responsible investment all draw on the same reconciled data, the regulated filing and the member narrative stop being two competing drafts and become two expressions of one position. The net-zero story the RI team has told for years is not retired by the new regime. It gains a financial spine: the same emissions and exposure data that demonstrates resilience to the regulator gives the stewardship narrative something solid to stand on.

None of this is a solved problem, and we would be wary of anyone who sold it as one. What we can offer is a way of working we have built alongside many of Australia's largest super funds: sitting as the operating layer above the data feeds rather than as another feed beside them, bringing listed and private holdings into one reconciled view tied back to the fund's own records, so finance and the responsible investment team draw on the same numbers with a clear line from source to disclosure. 

From there, finance can disclose with confidence, and the responsible investment team can keep speaking to members with meaning. Done this way, mandatory reporting is not a hollow obligation laid over the real work. It is the real work, made visible.
