A strong TCFD-aligned report provides a useful starting architecture for IFRS S2 because IFRS S2 integrates the four TCFD pillars and the 11 recommended disclosures. Transition is not, however, a re-labelling exercise.
Helps you decideWhich existing disclosures can be retained, which need greater specificity, and which new IFRS S1/S2 requirements need data, methods or approval?

ISSB·Decision guide·New standards and transition
The December 2025 amendments make targeted changes to IFRS S2 rather than replacing its GHG architecture. They clarify that a required jurisdictional or exchange method can be used for the affected part of an entity, permit required alternative GWP values for that part, allow an entity to limit Category 15 measurement to financed emissions, introduce transparency about derivatives and excluded financial activities, require a total Category 15 amount plus a financed-emissions subtotal when Category 15 is included, and refine industry-classification requirements for financed-emissions disclosures.
Helps you decideWhether to early apply, which reliefs are relevant, what data-model changes are needed, and how to prepare comparatives for 2027.
