What do Australian entities need to know as they implement mandatory sustainability reporting?
On 28 April 2025, the International Sustainability Standards Board (ISSB) released an exposure draft which proposes several amendments to the disclosure requirements for greenhouse gas emissions arising under IFRS S2 Climate-related Disclosures.
In summary:
- The proposed fast-track amendments would respond to application issues identified with IFRS S2
- The amendments are intended to be finalised by the end of 2025 to be available for early adoption for first-time application of mandatory sustainability reporting in Australia (subject to the feedback and redeliberation)
- Clarifications would explain that alternatives to the GHG Protocol and Intergovernmental Panel on Climate Change (IPCC) global warming potential (GWP) values could be used for part of an entity in some circumstances
- Mandatory disclosure of Scope 3 greenhouse gas emissions associated with investments (Category 15) would be limited to loans and investments, expressly excluding emissions associated with derivatives, facilitated emissions and insurance-associated emissions (with additional disclosure)
- Industry classification requirements when disaggregating financed emissions information for commercial banking and insurance activities would be more flexible.
The detail:
The proposed amendments resulted from application issues originally considered by the Transition Implementation Group on IFRS S1 and IFRS S2 (TIG) and were agreed by the ISSB at its January 2025 meeting.
The proposed amendments are as follows:
- Departures from using the GHG Protocol to measure emissions. The existing reference to using an alternative to the Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (2004) (GHG Protocol) when measuring greenhouse gas emissions would be clarified to explain an alternative measure could be used for part of an entity when a jurisdictional or exchange requirement applies to that part of an entity. For instance, where the National Greenhouse and Energy Reporting Scheme (NGER) applied to part of the entity, greenhouse gas emissions could be measured using NGER for that part of the entity and the GHG Protocol for the remainder
- Global warming potential values. Similar to the GHG Protocol proposals, an entity required by a jurisdictional authority or exchange to use global warming potential values other than those from the latest IPCC assessment available at the reporting date, can use those alternative GWP values when measuring emissions for part of an entity
- Disclosure of Scope 3 Category 15 greenhouse gas emissions:
- Limitation of disclosures. Entities would be permitted to limit disclosure of Scope 3 Category 15 (investments) greenhouse gas emissions to financed emissions attributed to loans and investments (including loans, project finance, bonds, equity investments and undrawn loan commitments). For these purposes, the proposals expressly exclude greenhouse gas emissions from derivatives (without providing a definition of a “derivative” due to potential GAAP and framework differences), facilitated emissions and insurance-associated emissions. However, entities could choose to disclose these emissions if they wish
- Transparency of exclusions. Entities would be required to provide information about excluded derivative and other financial activity emissions
- Industry classifications. The proposals would permit an entity with commercial banking or insurance activities to adopt an industry classification other than the Global Industry Classification Standard (GICS) for classifying counterparties when disaggregating financed emissions where required by a jurisdictional authority or exchange (which may include prudential reporting). Where more than one such requirement exists, the entity would be required to select one classification system. However, if the entity uses GICS in any part of the entity, it would be required to use GICS when disaggregating all financed emissions. Where the entity does not use GICS and is not subject to jurisdictional or exchange requirements, the entity could use an industry classification system of its choice. Entities would be required to disclose information about any alternative classification system used.
The ISSB intends to fast-track the amendments, expecting redeliberation to be completed in the second half of 2025. The exposure draft is open for a 60 day comment period until 27 June 2025.
On 29 April 2025, the AASB has issued an equivalent exposure draft, AASB ED SR2 Amendments to Greenhouse Gas Emissions Disclosures. The comment period ends on 2 June 2025.
