Sustainability report (Corporations Act)
Definition
A sustainability report is the statutory report required by section 292A of the Corporations Act. It contains the climate statements for the financial year, any notes to those statements, and the directors’ declaration. It is lodged with ASIC together with the financial report and the directors’ report, and it must be assured.

In practice
The report has three components and the third is the one directors focus on.
The climate statements are the AASB S2 disclosures: governance, strategy, risk management, and metrics and targets, including greenhouse gas emissions.
The notes explain, expand and disclose the judgements and methods behind the statements.
The directors’ declaration is the board’s statement about the report. For financial years commencing between 1 January 2025 and 31 December 2027 inclusive, it is modified so that directors declare they have taken reasonable steps to ensure the report is in accordance with the Corporations Act. After that transitional period, the declaration reverts to an opinion that the report complies.
The sustainability report is a distinct report, not a section of the annual report. It has its own statutory contents, its own declaration and its own assurance report.
What the assurer does with it
The assurer’s conclusion attaches to this report as a defined document, so the first thing they establish is its boundary: which pages are the sustainability report and which are surrounding annual-report content. They read the whole document, including unassured voluntary material, for material inconsistency with the assured information and with the financial report. They check that the declaration is inside the report, dated no earlier than the conclusion, names the correct entity and period, and uses the currently applicable form of words. They reject a sustainability report presented as a chapter of an ESG brochure with no identifiable statutory boundary.
Commonly confused with
The annual report and the voluntary ESG or sustainability report a business may already publish. The Corporations Act sustainability report is a separate statutory document with its own contents, its own declaration, its own assurance and its own lodgement form.
Timing and relief
The modified directors’ declaration applies for financial years commencing 1 January 2025 to 31 December 2027 inclusive. From financial years commencing on or after 1 January 2028 the declaration becomes an opinion that the report is in accordance with the Act.

Related questions
Do we have to do mandatory climate reporting?
−
You must prepare a sustainability report if you already lodge a financial report under Chapter 2M of the Corporations Act and you also meet one of the size, NGER or funds-under-management tests in section 292A. Both gates have to be passed: with no Chapter 2M obligation, section 292A never engages however large you are. Which of the three reporting groups you fall into decides which financial year is your first.
What does the board have to sign?
+
The directors’ declaration in the sustainability report. For financial years commencing between 1 January 2025 and 31 December 2027, directors declare they have taken reasonable steps to ensure the report complies with the Corporations Act. From financial years commencing 1 January 2028, they declare their opinion that it does comply.
Do we need comparatives in our first report?
+
No. AASB S2 relieves first-time reporters from disclosing comparative information in their first annual reporting period, and comparatives are required from year two. That means your year-one numbers and working papers will be looked at again, so build the year-one file as if it will be re-examined.
Where this sits commercially
Carbonhalo prepares the sustainability report and the file behind it; the assurance provider tests both.
