ISSB S1 & S2 Adoption: What Malaysian Corporates Need to Know

With Bursa Malaysia mandating climate-related disclosures, understanding the ISSB standards is no longer optional for listed issuers. Companies are expected to provide transparent and accurate reporting of climate risks and opportunities, aligned with ISSB S1 (General Requirements) and S2 (Climate-related Disclosures).

Key Considerations

• Mandatory Climate Disclosure: Issuers must now disclose climate-related risks and opportunities in a manner that is comparable, consistent and decision-useful for investors.
• Phased Implementation: Companies can adopt reporting gradually, starting with near-term climate disclosures and extending to more complex areas such as Scope 3 emissions over time.
• Practical Reliefs: The framework allows phased compliance, helping companies align reporting practices without overwhelming internal resources.
• Tools and Guidance: Companies can leverage advisory support, frameworks and internal assessments to implement ISSB-aligned disclosures effectively.

Implications for Malaysian Companies

Adopting ISSB S1 and S2 requires more than just producing reports. Organisations should ensure disclosures are well-structured, clearly linked to operational and strategic decisions and integrated into corporate governance and processes. Thoughtful reporting enhances transparency, improves stakeholder confidence and supports alignment with national and international sustainability goals.

Conclusion

Understanding and implementing ISSB S1 and S2 is a critical step for Malaysian corporates in the evolving sustainability landscape. By combining structured, high-quality disclosures with robust ESG integration, companies can meet regulatory expectations while providing actionable insights for boards, investors and stakeholders. Why the preparation has to start well before the first reporting year is the subject of IFRS S1 and S2 in Malaysia: what companies should be doing now.
