Two standards, one built on the other
S1 sets out how to report sustainability-related risks and opportunities that could affect the entity's prospects. S2 applies that same framework to climate.
- IFRS S1 — General requirements — governance, strategy, risk management and metrics.
- IFRS S2 — Climate-related disclosures, including Scope 1, 2 and 3 and scenario analysis.
- SASB metrics — Referenced by S1 as a source of industry-specific disclosure.
