Singapore is phasing in mandatory climate reporting based on the ISSB standards (IFRS S1 and IFRS S2). For many companies, the hardest part is not the emissions figures but the rest of IFRS S2: governance, strategy, climate scenario analysis, financial effects and transition planning. GreenCo helps SGX-listed and large non-listed companies prepare credible climate disclosures, and has supported SGX clients with their inaugural climate-related disclosures.
Singapore Climate Reporting Timeline
Following the extended timelines announced by ACRA and SGX RegCo in August 2025:
- STI constituents – Scope 1 and 2 emissions and other ISSB-based climate disclosures from FY2025; Scope 3 emissions from FY2026.
- Other listed issuers with market capitalisation of S$1 billion or more – Scope 1 and 2 emissions from FY2025; other ISSB-based climate disclosures from FY2028.
- Other listed issuers below S$1 billion – Scope 1 and 2 emissions from FY2025; other ISSB-based climate disclosures from FY2030.
- External limited assurance of Scope 1 and 2 emissions – from FY2029 for listed issuers.
- Large non-listed companies (annual revenue of at least S$1 billion and total assets of at least S$0.5 billion) – ISSB-based climate disclosures from FY2030, with limited assurance of Scope 1 and 2 from FY2032.
- Scope 3 – voluntary for non-STI listed issuers and large non-listed companies until further notice.
In July 2026, ACRA also consulted on draft Singapore Sustainability Disclosure Standards, which would make SFRS S2 a standalone mandatory climate standard. These proposals are not yet effective, so companies should continue to follow the SGX Listing Rules and Practice Note 7.6 while preparing for what comes next. We confirm the position for your reporting year at scoping.
