AASB S2 Climate Reporting
Mandatory climate reporting is now law. We get you from scattered data to an assured Sustainability Report - on the Microsoft platform you already own.
End-to-end delivery of Australia's mandatory climate-related financial disclosures under AASB S2 and the ASRS - governance, strategy, risk, and Scope 1, 2 and 3 metrics - built on Microsoft Sustainability Manager and Fabric with a full assurance evidence trail.
Does your organisation have to report under AASB S2?
Mandatory climate reporting under AASB S2 began for financial years starting on or after 1 January 2025, and is phasing in across three groups of companies. Group 1 covers the largest entities and every business over the NGER publication threshold. Boards are now personally accountable for a Sustainability Report that sits inside the annual report and faces external assurance - yet the emissions data needed to produce it is scattered across spreadsheets, utility portals, finance systems and suppliers. Most first-time reporters underestimate how long a defensible, audit-ready baseline takes to build.
We deliver the whole obligation as one programme, and we start with a fixed-fee Readiness Assessment so the first step is small and the cost is known. We map your reporting group and timeline, stand up Microsoft Sustainability Manager and a Fabric ESG model, ingest and validate your Scope 1, 2 and 3 activity data, and produce an AASB S2-aligned report pack across all four pillars - governance, strategy, risk management, and metrics and targets - with every number traceable to source evidence for your assurance provider.
Reporting group & timeline assessment
We confirm which group you fall into, your first reporting year, and exactly what you must disclose and when - Scope 1 and 2 from year one, material Scope 3 from year two.
- Group 1, 2 or 3 determination against the size and NGER thresholds
- Scope 3 and financed-emissions applicability check
- Gap analysis against the four AASB S2 pillars
Governed emissions data model
Microsoft Sustainability Manager and a Fabric ESG model consolidate Scope 1, 2 and 3 with activity-based and spend-based methods, emission factors, and full restatement history.
- NGER and GHG Protocol aligned factor library
- Data validation and quality controls in Dataverse
- Restatement and version history for every figure
Four-pillar disclosure pack
A report pack that answers all four AASB S2 pillars - governance, strategy, risk management, and metrics and targets - refreshed automatically as your data updates.
- Governance and oversight documentation
- Climate scenario analysis aligned to NGFS and IPCC pathways
- Metrics, targets and transition-plan reporting
Assurance evidence trail
Every disclosed number links back to source evidence, so your assurance provider tests the trail instead of chasing you for it.
- One-click drill-down from disclosure to source
- Audit snapshots and data lineage captured automatically
- Approval and change-control workflows
What an assured AASB S2 report gives you
Compliant the first year
Assurance-ready
A report pack built to pass external assurance at the first attempt, not after a restatement.
Months back on the reporting cycle
75% faster reporting
A governed data model turns a months-long manual scramble into a repeatable close.
On the platform you already own
No new platform
Built on Microsoft, so you avoid a new standalone carbon tool and its separate licence.
Built for the people who run the process
Three roles have to agree before an approach to market changes. Here is what each of them gets.
The CFO
You signed off on financial statements for years. Now a climate report sits beside them, under the same scrutiny.
The numbers live outside finance, the methodology is unfamiliar, and the auditor will test both. You need the same rigour you apply to the ledger, applied to emissions.
- A report pack built to survive external assurance the first year
- Every emissions figure traceable to source evidence in one click
- A repeatable close process, not a one-off consulting scramble
The Company Secretary
The board is now personally accountable for a disclosure most directors have never had to make.
You need to brief the board on the obligation, the timeline, and the governance the standard demands - without becoming a climate expert yourself.
- A clear map of your reporting group and first reporting year
- Governance and oversight documented to the AASB S2 pillar
- Board-ready summaries, not raw carbon data
The Sustainability Lead
You have owned emissions data for years. Now finance and the auditor want it to their standard.
Your spreadsheets got you a footprint. They will not get you through assurance. You need a governed data model without losing the methodology knowledge you already hold.
- Your methodology preserved, but in an auditable, governed system
- Restatement and version history handled automatically
- Time back from re-keying data to actually reducing emissions

Frequently asked questions
Which AASB S2 reporting group are we in?
- Group 1 is any entity meeting two of three thresholds: $500 million consolidated revenue, $1 billion consolidated gross assets, or 500 employees, plus NGER reporters above the publication threshold. Group 2 lowers the thresholds to $200 million, $500 million and 250 employees and adds all other NGER reporters and asset owners with $5 billion or more under management. Group 3 is $50 million, $25 million and 100 employees. The test is applied at the end of each financial year.
When is our first AASB S2 report due?
- Group 1 reports for financial years beginning on or after 1 January 2025, Group 2 from 1 July 2026 and Group 3 from 1 July 2027. The sustainability report is lodged with the annual financial report, so a 30 June year-end Group 2 entity's first report covers the year to 30 June 2027.
What must an AASB S2 disclosure contain?
- Four pillars: governance of climate-related risks and opportunities, strategy including scenario analysis and any transition plan, risk management processes, and metrics and targets including Scope 1, 2 and 3 greenhouse gas emissions. Scope 3 is not required in the first reporting year.
What assurance is required?
- Limited assurance over Scope 1 and 2 emissions from the first year, phasing up under the AUASB pathway to reasonable assurance over the whole climate disclosure for financial years beginning on or after 1 July 2030. Every figure needs evidence an auditor can retrace, which is why we build the platform around lineage from day one.
We also operate in New Zealand. Is that a separate project?
- No. The Aotearoa New Zealand Climate Standards (NZ CS 1 to 3) predate the ISSB standards but share the same TCFD structure as AASB S2: governance, strategy, risk management, and metrics and targets. The External Reporting Board plans to align NZ CS more closely with IFRS S2, with consultation in 2026 and revised standards expected in 2027. We run one emissions model and one governance record, and produce the NZ climate statement alongside the Australian disclosure.
