AASB S2 climate reporting: practical lessons for CFOs from Group 1 reporters

Mandatory climate reporting under AASB S2 is becoming a key finance, governance and risk management priority for Group 2 and Group 3 organisations. Insights from December 2025 Group 1 reports show that success depends on building a robust, assurance-ready reporting process rather than simply preparing a disclosure. CFOs should start early by establishing clear governance, assessing climate risks, developing proportionate scenario analysis, preparing for Scope 3 emissions reporting, and integrating climate reporting into financial planning. By learning from early adopters, organisations can create a practical, credible reporting framework that meets regulatory expectations and supports informed decision-making.
