IFRS S2 adoption by jurisdiction
Scope of this page
What it covers. Jurisdictions that have adopted, aligned with, or are consulting on the ISSB Standards, plus two regimes included for comparison because their reporting populations overlap heavily: the European Union (ESRS under the CSRD) and the US state of California. For each, the local standard, the regulator, who is caught, the first mandatory reporting period, the assurance requirement, and any transition reliefs beyond those in IFRS S1 and IFRS S2.
What it does not cover. Voluntary frameworks, sector guidance, and jurisdictions with no public regulatory position. It is not legal advice, and it does not reproduce the requirements themselves - each row links to the primary source so you can read them.
How it is verified. Every row is taken from a primary source: an IFRS Foundation jurisdictional profile or snapshot, a regulator, or a standard-setter. Where a source does not state a field, the cell reads not verified rather than an estimate. Last verified 2026-08-12. Reviewed monthly.

How to read the status column
Final follows the IFRS Foundation's own distinction: it publishes a jurisdictional profile when a jurisdiction's approach is "finalised and no longer subject to consultation". In progress corresponds to a snapshot, published where the regulatory status is still in progress. Separate regime marks the two rows that are not ISSB adoptions at all.
A final status describes the regulatory decision, not the assurance regime. Several jurisdictions have settled their reporting requirements while leaving assurance open, and those cells say so.
What the table shows
Three things are worth noting across the rows, because they are visible in the sources rather than inferred.
Assurance timing varies more than reporting timing. Turkiye requires limited assurance from the first year of reporting. Japan and Bangladesh require it from the second. Singapore sets FY2029 for listed issuers. Hong Kong SAR does not require it yet. Several jurisdictions have a mandatory reporting date and no assurance date at all.
Several jurisdictions extend the IFRS reliefs rather than adopting them unchanged. Japan allows disclosures to follow the financial statements for two annual reporting periods, one year longer than IFRS S1 paragraph E4. Turkiye grants an extra year of Scope 3 relief. Australia runs the other way: the IFRS S1 first-year relief is not available in AASB S2.
Climate-first is common. Malaysia, Singapore and Hong Kong SAR begin with climate requirements rather than the full sustainability scope. The mechanics of that choice are set out in the IFRS S2 transition reliefs.
