1. The Core Architecture of IFRS S1
IFRS S1 requires an entity to disclose information about all sustainability-related risks and opportunities that could reasonably be expected to affect the entity’s cash flows, its access to finance, or its cost of capital over the short, medium, or long term. Aligned with the historic TCFD architecture, both IFRS S1 and S2 mandate structural reporting across four core pillars:

(Note: Pillar 4 is Metrics and Targets, tracking key performance indices)

2. General Presentation Principles and Timing
  • Reporting Entity: The sustainability disclosures must cover the exact same reporting entity as the related financial statements (e.g., parent plus consolidated subsidiaries). 
  • Timing Synchronicity: An entity is contractually mandated to publish its sustainability disclosures at the same time as its primary financial statements, creating a single, unified reporting cycle.
