Draft legislation to mandate climate reporting in Australia

This article was updated on 31 January, 2024

On Friday, 12 January 2024, the Australian Government released draft legislation for significant reforms establishing Australia’s climate risk disclosure framework. The draft legislation amends the Australian Securities and Investment Commission Act 2001 and the Corporations Act 2001 to introduce mandated climate-related financial disclosures in a separate sustainability report, as part of some entities’ annual reports. Entities will also be required to obtain an assurance report over the sustainability report from their financial auditors.

Who will be required to begin climate-related reporting?

Entities subject to mandatory climate-related financial disclosure would be phased in three groups, over a four-year period as in the table below.


Large entities and their controlled entities meet at least two of three criteria

National Greenhouse Energy Reporting (NGER) reporters

Asset owners


Consolidated revenue

End of financial year consolidated gross assets

End of financial year employees



Group 1

$500 million or more

$1 billion or more

500 or more

Who will be excluded from mandatory climate-related reporting?

  • Small and medium businesses below the relevant size thresholds will be exempt.
  • Entities that are exempt from lodging financial reports under Chapter 2M of the Corporations Act, including where exemptions have been made through the Australian Securities and Investment Commission (ASIC) class orders or where the entity is registered with the Australian Charities and Not-for-profits Commission (ACNC).

Group 3 materiality exemption

Group 3 entities (that is, entities in-scope for reporting but do not meet the thresholds for Group 2) would only be required to make climate-related financial disclosures in line with the climate disclosure standards if they face material climate-related risks or opportunities for the financial reporting period. Where Group 3 entities assess that they do not have material risks or opportunities, they would only be required to disclose a statement to that effect.

What will be disclosed?

The Government endorses full adoption of the International Sustainability Standards Board’s (ISSB’s) IFRS S2 Climate-related Disclosures standard in Australia, with modifications limited to those necessary to ensure standards are fit for Australia. This should incorporate Australia’s greenhouse gas emissions estimation methodologies and international climate change commitments. The Government also supports the adoption of the ISSB’s IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information, but only where required to give effect to climate disclosure standards.

Where will sustainability disclosures be required?

Climate-related financial disclosures will sit within a sustainability report, which will form the fourth report required as part of annual financial reporting obligations and be contained in an entity’s annual report.

An entity’s annual report is proposed to consist of the following:

  1. Annual financial report
  2. Annual sustainability report
  3. Directors’ report, and
  4. Auditor’s report.

The annual financial report consists of the following:

The annual sustainability report is proposed to consist of the following:

  • The climate statements for the year
  • Any notes to the climate statements, and
  • The directors’ declaration about the statements and notes.

Timing of annual report lodgement, which will now also include a sustainability report, including for those required to lodge with ASIC will stay consistent with current requirements under section 319 of the Corporations Act.

Assurance requirements

Climate disclosures will be subject to similar assurance requirements to those currently in the Corporations Act for financial reports. They will require entities to obtain an assurance report from their financial auditors, who will also use technical climate and sustainability experts where required. These requirements will be set out in Australian assurance standards for climate disclosures.

Modified liability

Entities will be provided relief for a fixed three-year period for disclosures relating to Scope 3 emissions and certain climate-related forward-looking statements. For reports issued between 1 July 2025 and 30 June 2028, only the regulator will be able to bring action relating to breaches of relevant provisions made in disclosures of scope 3 emissions and climate-related forward-looking statements, and the remedies available to the regulator will be limited to injunctions and declarations. Beyond this period, the existing liability arrangements will apply.


Consultation for the draft legislation is now open and submissions will close on 9 February 2024.
