In brief

What this profile covers

IFRS S1 and S2 are the first global baseline sustainability disclosure standards, issued by the International Sustainability Standards Board in 2023. IFRS S1 sets general requirements for disclosing sustainability-related risks and opportunities; IFRS S2 covers climate, incorporating the TCFD architecture (governance, strategy, risk management, metrics and targets) and requiring Scope 1–3 emissions disclosure under GHG Protocol rules. The standards are investor-focused: materiality is financial — information useful to capital providers. Jurisdictions adopt them through their own legal processes, so whether reporting is mandatory depends on local law, and the ISSB has issued amendments on GHG disclosure requirements to ease application. SASB Standards survive as ISSB-maintained industry guidance. The ISSB's mandate is consolidation: it absorbed the TCFD's recommendations, houses the SASB Standards, and works through a Jurisdictional Guide to ease adoption. Regulators from the UK to Japan, Singapore and Australia have built or proposed regimes on the IFRS baseline, making S1/S2 the likeliest global common denominator for investor-grade sustainability disclosure. Using this framework does not by itself verify data accuracy, legal compliance or sustainability performance.
