On 25 August 2025, SGX RegCo and the Accounting and Corporate Regulatory Authority (ACRA) announced an extension of timelines for implementing climate reporting for both listed companies and large non-listed companies (Large NLCos)[1].
Singapore took a decisive step forward in turning its climate ambition into action. The Singapore Exchange Regulation (SGX RegCo) finalised amendments to its Listing Rules[2] (and Sustainability Reporting Guide) to incorporate the International Financial Reporting Standards (IFRS) Sustainability Disclosure Standards[3] (International Sustainability Standards Boards (ISSB) standards) into its sustainability reporting regime. This is off the back of recommendations[4] released by the Sustainability Reporting Advisory Committee (SRAC)[5] in July 2023 to advance climate reporting in Singapore for both listed and non-listed companies.
The announcement comes barely a year after the initial ruling, with the justification for the changes being an uncertain global economic landscape, and feedback suggesting that greater consideration was needed for the varying levels of resources available and readiness within businesses to undertake climate reporting. The extension is meant to provide more time, especially for smaller listed companies, to develop their climate reporting capabilities. The large listed companies who are Straits Times Index (STI) constituents are expected to continue leading the way with an extension given only for external assurance.
While the delay of mandatory reporting deadlines may offer temporary relief for many companies, stakeholder expectations for credible, consistent, and comparable sustainability information remain unchanged. In the absence of mandated disclosures, companies that maintain their momentum and demonstrate clear intent and preparedness will distinguish themselves - laying a stronger foundation for long-term resilience and stakeholder trust.
