IFRS S1

IFRS S1 is the International Sustainability Standards Board (ISSB) standard that sets the general requirements for disclosing sustainability-related financial information. It is designed to give investors decision-useful information about a company's sustainability-related risks and opportunities that could affect its prospects.

The ISSB sits under the IFRS Foundation, the body behind the IFRS accounting standards, and aims to create a global baseline for sustainability disclosure that jurisdictions can build on. IFRS S1 covers core content similar to the TCFD pillars: governance, strategy, risk management, and metrics and targets, applied across sustainability topics rather than climate alone.

A company applying IFRS S1 discloses material information about all sustainability-related risks and opportunities, and uses IFRS S2 for climate specifically. The standards are not automatically law; each jurisdiction decides whether and how to adopt or require them.

IFRS S1 fluency is increasingly expected in corporate reporting, investor relations, and assurance roles as more markets adopt the ISSB baseline.
