Limited Assurance in Singapore: Are You Prepared for FY2027?

Singapore is leading the region in climate-related reporting, and the next big shift is just around the corner: limited assurance. For SGX-listed companies, it becomes mandatory from FY2027. For large non-listed companies, it will apply by FY2029.

While most businesses are still trying to wrap their heads around climate disclosures, assurance is quickly becoming the next hurdle. The question is: Are you ready?

What Is Limited Assurance?

Limited assurance is an independent review of your ESG or climate disclosures, especially emissions data, to confirm that nothing has come to the auditor’s attention to suggest the information is materially misstated.

It’s not as deep as “reasonable assurance” (like in financial audits), but it still requires:

• Consistent, traceable data
• Documented internal controls
• Clear governance and accountability
• Evidence trails to support claims

In short, if you’re reporting emissions or climate-related risks, you’ll need to prove them.

Why FY2027 Matters

Under Singapore’s Climate Disclosure Roadmap:

• Listed issuers must undergo limited assurance on Scope 1 and 2 emissions from FY2027
• Large non-listed companies follow suit by FY2029
• Scope 3 may be phased in later, but preparatory work is expected in the meantime

Companies that start preparing now will be in a far stronger position than those who wait for the deadline.

What Will You Need to Show?

To meet assurance requirements, your ESG data must be:

• Complete and accurate – No gaps, no guesses
• Traceable – From source to final report
• Consistent with standards – Aligned with ISSB S2, SGX guidance, and industry benchmarks
• Auditable – With clear documentation, ownership, and controls

You’ll also need to show how the data was calculated, who reviewed it, and how material risks were assessed.

Common Gaps That Delay Readiness

• Fragmented or manual data collection
• No clear internal roles for ESG data ownership
• Unclear methodology for Scope 1 and 2 calculations
• No process for internal review before publishing reports

These gaps are all fixable but only if they’re identified early.
