# AASB S2 reporting

> What Australia's mandatory climate disclosure standard requires, when each group starts, which first-year reliefs apply, and which parts Salvidia produces for you.

**AASB S2 Climate-related Disclosures** is Australia's mandatory climate reporting standard, the local implementation of IFRS S2. It sits within the Australian Sustainability Reporting Standards and applies to entities by size, phasing in over three groups.

Salvidia produces the emissions metrics AASB S2 requires. It does not produce the whole disclosure, and no carbon platform does. This page sets out everything S2 asks for so you can see which parts are covered and which your finance team and advisors must assemble.

<Note>
  This page is a plain-language summary, not legal or accounting advice. Thresholds and dates have moved more than once. Confirm your group and obligations with your auditor or advisor against the current AASB text.
</Note>

## Who reports, and when

Three groups, by entity size, each meeting at least two of three thresholds.

| Group       | Thresholds, meeting any two                          | First reporting periods beginning |
| ----------- | ---------------------------------------------------- | --------------------------------- |
| **Group 1** | Revenue ≥ \$500m · assets ≥ \$1b · ≥ 500 employees   | On or after 1 January 2025        |
| **Group 2** | Revenue ≥ \$200m · assets ≥ \$500m · ≥ 250 employees | On or after 1 July 2026           |
| **Group 3** | Revenue ≥ \$50m · assets ≥ \$25m · ≥ 100 employees   | On or after 1 July 2027           |

Group 1 is already reporting. Group 2 began with periods starting 1 July 2026. Certain entities with emissions reporting obligations under the NGER scheme are captured regardless of size.

## The four pillars

AASB S2 follows the TCFD structure. Emissions data is one part of the fourth pillar.

<Columns>
  <Column>
    <Card title="Governance">

  <Column>
    <Card title="Metrics and targets">
      Gross Scope 1, 2, and 3 emissions, industry-based metrics, internal carbon prices, remuneration linkage, and any climate targets you have set.
    </Card>
  </Column>
</Columns>

Only the fourth pillar draws on your carbon inventory. The first three are governance and strategy work produced inside your business.

## The emissions requirements in detail

This is the part Salvidia feeds directly.

* **Gross Scope 1, 2, and 3**, disclosed separately, in tonnes CO₂e
* Measured **in accordance with the GHG Protocol Corporate Standard, 2004**, unless a jurisdictional requirement applies. See [GHG Protocol alignment](/methodology/ghg-protocol-alignment).
* **Scope 2 reported location-based**, with market-based information disclosed where you hold contractual instruments
* **Scope 3** including the categories that apply to you, and, for financial institutions, financed emissions
* The **consolidation approach** used and the **measurement approach, inputs, and assumptions** behind the figures
* Disaggregation between the **consolidated accounting group** and other investees where relevant

## First-year reliefs

The standard grants transitional relief, and it is worth using rather than delaying your whole disclosure to achieve perfection:

* **No comparative information** required in your first reporting period
* **Scope 3 deferred** to your second reporting year
* **Scenario analysis relief** in the first year
* Assurance requirements phase in over time rather than applying in full immediately

Scope 3 being deferred is the relief most often misread. It buys you one year. Given that Scope 3 is usually the majority of the footprint and the hardest to collect, the sensible move is to build it during the year you are not yet required to publish it.

## Targets

If you have set climate targets, S2 requires you to disclose the objective, the scope covered, the base year and period, milestones, and how you are tracking against them, plus whether the target was validated by a third party.

S2 does not require you to have a target. It requires you to disclose the ones you have, accurately. See [Science-based targets](/guides/setting-science-based-targets) and [Pathway](/platform/pathway-and-targets).

## If you supply a reporting entity

You may have no obligation of your own and still be affected. Your customer's Scope 3 includes what they buy from you, so as Groups 1 and 2 come into effect their procurement teams start asking suppliers for emissions data.

That request usually arrives with a deadline attached to their reporting cycle, not yours. Having a credible, boundary-stated number ready is becoming a condition of keeping large customers rather than a nice-to-have. See [Standards and frameworks](/methodology/standards-and-frameworks).
