IFRS S2 Amendments: GHG Disclosure Changes Explained

Published 12 September 2026

What the December 2025 IFRS S2 amendments mean for greenhouse-gas disclosures, data controls and climate-risk governance.

Executive answer

The targeted IFRS S2 amendments respond to implementation questions around greenhouse-gas emissions disclosures. For risk teams, the significance extends beyond reporting: changes to measurement boundaries and reliefs can affect the comparability of emissions-based indicators used in transition-risk analysis.

What changed

Reporting choices should be documented so that users understand what is included, which method is used and where estimates are necessary. A disclosed metric can be compliant yet still require caution when used for pricing, credit or portfolio steering.

Implications for financial institutions

Institutions should align finance, sustainability, risk and audit ownership. Controls over source data, estimation, restatement and sign-off are essential because climate disclosures increasingly feed management information and external decisions.

Relevance to Quantica Climate Risk Model

Quantica Climate Risk Model may support governed interpretation of disclosed information, but it should never imply that one reported emissions number fully represents transition risk. Internal analytics and transformations are not described publicly.

Conclusion

For ifrs s2 amendments: ghg disclosure changes explained, the practical priority is disciplined interpretation: connect authoritative evidence to a defined decision, preserve the limitations, and ensure accountable review. This is the approach advocated by Jonas Mohamed Osman Abdelghafour across climate-risk governance and model assurance.
