The current roadmap
| Organisation / tier | Scope 1 & 2 GHG | Other ISSB-based climate disclosures | Scope 3 | Limited assurance on Scope 1 & 2 |
|---|---|---|---|---|
| STI constituents Constituent on 30 Jun 2025 | FYC 2025 | FYC 2025 | FYC 2026 | FY2029 |
| Non-STI listed, market cap ≥ S$1bn 30 Jun 2025 test; special rule for later listings | FYC 2025 | FYC 2028 | Voluntary until further notice | FY2029 |
| Other SGX-listed issuers | FYC 2025 | FYC 2030 | Voluntary until further notice | FY2029 |
| Large non-listed companies Revenue ≥ S$1bn and assets ≥ S$500m, unless exempt | FY2030 | FY2030 | Voluntary until further notice | FY2032 |
The six SGX primary components
Every SGX-listed issuer must prepare an annual sustainability report under Rule 711A. Rule 711B and Practice Note 7.6 require the report to address six primary components:
- Material environmental, social and governance factors, including the selection process and business relevance.
- Climate-related disclosures applicable to the issuer’s tier.
- Policies, practices and performance for each material factor, with quantitative information where meaningful.
- Targets across useful time horizons and performance against previously disclosed targets.
- The sustainability reporting framework or frameworks used, and the extent of application.
- A Board statement and the associated governance structure for sustainability practices.
Internal review, publication and assurance
The sustainability reporting process must be subject to internal review. The report is normally issued at the same time as the annual report, published on SGXNet and the company website. Where external assurance has been conducted, SGX provides a transitional route allowing publication no later than five months after financial year end, with a summary in the annual report if the full report follows later.
External limited assurance of Scope 1 and 2 GHG emissions becomes mandatory from FY2029 for listed companies and FY2032 for large non-listed companies. The wider sustainability report may also be assured voluntarily.
Large non-listed company test and exemption
A large non-listed company is in scope when it meets both thresholds: annual revenue of at least S$1 billion and total assets of at least S$500 million. A parent-reporting exemption may be available where the entity is included in a publicly available parent report prepared using ISSB-based local standards or an accepted equivalent. Confirm the detailed conditions rather than assuming group reporting automatically creates an exemption.
What management should do now
Confirm the tier
Document the market-cap test, STI status, financial year start and any parent-reporting position.
Map requirements
Create a disclosure matrix linking every requirement to an owner, evidence source and approval route.
Stabilise emissions
Lock organisational boundaries, methods, emission factors, controls and explanations for changes.
Build IFRS S2 capability
Even before mandatory dates, develop governance, risk, scenario and financial-effects processes progressively.
Plan assurance
Design controls and retain evidence before the assurance year, not after the report is drafted.
Track updates
ACRA is developing local sustainability disclosure standards; monitor finalisation and implementation guidance.
