SGX Extends Climate Reporting Deadlines: What Companies Should Know About Sustainability Reporting in Singapore

On 25 August 2025, the Singapore Exchange Group (SGX) and the Accounting and Corporate Regulatory Authority (ACRA) announced extended timelines for climate-related disclosure requirements. This update is crucial for companies engaged in sustainability reporting in Singapore. While this extension provides more time for preparation, it also underscores the importance of staying informed about regulatory obligations. Companies that take a proactive approach now will be better positioned to meet mandatory climate reporting requirements and demonstrate a genuine commitment to sustainability. 

What the Updated Timelines Mean for Mandatory Climate Reporting 

Here's a snapshot of the key revisions in the climate reporting timeline: 

• Scope 1 and 2 greenhouse gas emissions: Mandatory for all listed companies from FY2025. 

• Scope 3 emissions: Mandatory for STI-listed companies from FY2026; optional/delayed for others. 

• External limited assurance for Scope 1 and Scope 2 emissions: Deferred to FY2029 for all listed companies. 

• Other ISSB-based climate-related disclosures (CRD) — governance, strategy, risk management, metrics and targets: 

• STI constituents → mandatory from FY2025. 

• Non-STI listed companies with market cap ≥ SGD 1B → mandatory from FY2028. 

• Non-STI listed companies with market cap < SGD 1B → mandatory from FY2030. 

For large non-listed companies (Large NLCos): 

• ISSB-based CRD (including Scope 1 & 2) deferred to FY2030. 

• External limited assurance for Scope 1 & 2 deferred to FY2032. 

  
  

These phased timelines give organisations time to strengthen their internal processes, but they don't reduce the need to track obligations and deadlines carefully. Scope 1 & 2 reporting from FY25 is a firm requirement, meaning companies need to act immediately.  

The Role of a Legal Register in Environmental Risk Management 

A legal register is a central tool for tracking regulatory obligations and supporting environmental risk management. For companies operating in Singapore, it can include updates on environmental regulations, energy efficiency and green building requirements, carbon reporting obligations, and other compliance deadlines relevant to sustainability initiatives. 

The value of a legal register lies in awareness and planning: 

• Track critical deadlines: Know when reporting obligations apply to your organisation. 

• Stay informed of updates: Ensure that any changes to rules, thresholds, or reporting standards are recorded. 

• Plan ahead: Use the register as a reference to prioritise actions and allocate resources for climate risk management. 

  
  

Turning Compliance into Action: Implementing ISSB Standards

Once obligations are clear, organisations face the challenge of acting on them in practice. This is where ESC's sustainability advisory services come in. Our sustainability consultants help companies interpret requirements, design sustainability reporting frameworks, and implement processes to meet ISSB-aligned climate-related disclosures. 

For example: 

• Advising on climate risk assessments and governance structures in line with TCFD requirements. 

• Supporting greenhouse gas emissions tracking and data collection for Scope 1 and Scope 2 emissions. 

• Preparing companies for future Scope 3 emissions reporting and sustainability assurance readiness. 

• Developing a comprehensive sustainability roadmap that aligns with IFRS S1 and IFRS S2 standards. 

  
  

In essence: 

• The legal register tells you what you must comply with in terms of sustainability disclosure standards. 

• ESC advisory services show you how to act on it responsibly and efficiently, ensuring compliance efforts translate into meaningful sustainability outcomes. 

  
  

The Benefits of Proactive Sustainability Reporting 

Engaging with both a legal register and expert sustainability advice offers multiple benefits: 

• Reduced risk of non-compliance by having a clear picture of obligations and climate-related financial risks. 

• Efficient reporting by linking compliance requirements to actionable processes within your sustainability reporting framework. 

• Stronger stakeholder confidence through proactive management of environmental and climate obligations. 

• Strategic advantage for companies that turn compliance into credible sustainability performance. 

• Potential financial support through initiatives like the sustainability reporting grant offered by Singapore's government. 

  
  

Takeaways for Sustainability Reporting in Singapore 

The SGX extension provides breathing room—but proactive planning is key. Companies should ensure their legal register is up to date with all relevant reporting obligations and deadlines. Beyond compliance, ESC's sustainability experts can help translate these obligations into practical reporting and operational improvements that meet ISSB standards and stakeholder expectations. 

By combining a legal register with ESC's sustainability advisory services, businesses can position themselves as leaders in sustainable practices—turning regulatory requirements into real business value. This approach is particularly crucial as Singapore cements its position as a sustainable finance hub and as scrutiny on large non-listed companies increases.
