What is ISSB (IFRS S1/S2)?
IFRS S1 and IFRS S2 are the global baseline sustainability disclosure standards from the International Sustainability Standards Board (ISSB). S1 sets general requirements for disclosing sustainability-related risks and opportunities that affect a company’s prospects. S2 covers climate: governance, strategy, risk management, and metrics and targets, including Scope 1, 2 and 3 greenhouse gas emissions.
Who it applies to
It is voluntary unless a country or exchange requires it. A growing number of jurisdictions adopt it, including Singapore, Malaysia and Australia (as AASB S2), and the UK has published its own versions (UK SRS).

- Mapping between ISSB, ESRS and GRI, so one data set feeds more than one report.
- Assurance-ready audit trails.
Common questions about ISSB (IFRS S1/S2)
What is the difference between ISSB and ESRS?
ISSB standards focus on what sustainability issues mean for a company’s value (financial materiality). ESRS also require the company’s impact on people and the environment (double materiality). Many companies need to understand both.
Is ISSB mandatory?
Not by itself. It is mandatory only where a country or exchange has adopted it, as in Singapore, Malaysia and Australia.
