Singapore extends timelines for climate reporting requirements

The Accounting and Corporate Regulatory Authority (ACRA) and Singapore Exchange Regulation (SGX RegCo) have extended the timelines for implementing ISSB-based climate reporting and external assurance requirements for listed companies and large non-listed companies to support capability development.

• Updated mandatory timelines for listed companies: three-tier approach by market capitalisation (i) STI constituents, (ii) non-STI listed companies with market capitalisation of S$1 billion and above, and (iii) non-STI listed companies with market capitalisation less than S$1 billion; Scope 1 and 2 GHG emissions mandatory from FY2025 for all listed companies; Scope 3 mandatory for STI constituents from FY2026; Other ISSB-based CRD mandatory for STI from FY2025, for non-STI ≥ S$1 billion from FY2028, and for non-STI < S$1 billion from FY2030; external limited assurance for Scope 1 and 2 deferred to FY2029 for all listed companies. (Market-cap threshold assessed as at close of market on 30 June 2025.)

• Large non-listed companies and capability support: ISSB-based CRD (including Scope 1 and 2) deferred to FY2030 for Large NLCos; Scope 3 remains voluntary until further notice; external limited assurance deferred to FY2032 for Large NLCos. Companies are directed to tap the Sustainability Reporting Grant (SRG) administered by EDB and EnterpriseSG (application deadlines updated). The extension responds to feedback from SBF and aims to allow smaller companies more time to build reporting processes.
