AASB S2 guide

Your practical guide to Australia’s mandatory climate-related financial disclosure standard.

The AASB S2 standard, part of the Australian Sustainability Reporting Standards (ASRS), marks a new era of climate accountability for large Australian entities. This guide breaks down what the standard requires, how it aligns with global frameworks like IFRS S2 and TCFD, and what steps organisations must take to prepare.

Developed for Australian reporting entities, finance teams, and institutional investors, this guide explains:

• What climate-related disclosures are mandatory under AASB S2
• How to report Scope 1, 2, and 3 emissions (including financed emissions)
• What’s expected for scenario analysis, financial impact reporting, and targets
• How assurance will be phased in over time, and what that means for your organisation

It also highlights how Emmi’s Carbon Diagnostics platform can support audit-ready reporting, robust emissions analysis, and investment-grade climate risk insights, all tailored to meet ASRS requirements.
