View all As we move into 2026, the Australian Sustainability Reporting Standards (ASRS) landscape is shifting from theoretical preparation to tangible reality. At ERM, we’re actively supporting businesses of all sizes on their Australian Accounting Standards Board (AASB) S2 disclosure journey. There’s been valuable lessons learnt as the first tranche of Group 1 reporters prepare to release their inaugural ASRS-aligned financial reports. If 2025 was the year of laying the foundations – where finance and sustainability teams focused on establishing robust data architecture, fortifying climate governance frameworks, and reshaping internal responsibilities – then 2026 is the year for delivery. With the first mandatory reports expected from mid March, organisations will soon have a clearer picture of what ‘good’ looks like, where challenges remain and how reporting processes can be strengthened.
We developed this updated guide to bring together our ASRS thought leadership and the practical lessons we’ve learned from working alongside clients throughout their first year of preparation. It consolidates our frontline insights on common challenges, effective reporting processes and the emerging expectations shaping Australia’s climate-related financial disclosures.
Whether you’re preparing your first report, refining internal workflows or gearing up as a future reporter, this guide will help you navigate the ASRS landscape with greater clarity and confidence.
