IFRS S1 Explained: What Malaysia's PLCs Need to Disclose About Sustainability Risks & Opportunities

For many Malaysian public listed companies, the term "IFRS S1" is still unfamiliar territory. Yet from 1 January 2026, all Group 2 Main Market PLCs must prepare their sustainability reports in full compliance with IFRS S1. This post breaks down exactly what IFRS S1 requires and what your company must start doing now.

What Is IFRS S1?

IFRS S1, formally known as IFRS Sustainability Disclosure Standard 1 (General Requirements for Disclosure of Sustainability-related Financial Information), is published by the International Sustainability Standards Board (ISSB). It sets out the baseline requirements for how companies must communicate sustainability-related risks and opportunities that are relevant to their financial performance.

Bursa Malaysia has adopted IFRS S1 as the mandatory framework for all Main Market PLCs under the National Sustainability Reporting Framework (NSRF).

The Four Pillars of IFRS S1

IFRS S1 is structured around four core disclosure pillars that companies must address in their sustainability reports:

1. Governance: Companies must disclose the board's and management's oversight of sustainability risks and opportunities. This includes who at the board level is responsible, how often sustainability is reviewed, and how management incentives are linked to sustainability performance.

2. Strategy: Companies must explain how sustainability-related risks and opportunities affect their business model, strategy, and financial planning. This is where you connect ESG to your business identity — not just tick boxes.

3. Risk Management: Companies must describe their processes for identifying, assessing, prioritising, and managing sustainability risks — and how these processes are integrated into the overall enterprise risk management framework.

4. Metrics & Targets: Companies must disclose quantitative information on material sustainability matters, including the metrics used and any targets set. For Group 2 companies, Bursa requires three years of comparative quantitative data once fully embedded.

What Does "Material" Mean in IFRS S1?

IFRS S1 uses a concept called "materiality" to determine what must be disclosed. A sustainability matter is material if it could reasonably be expected to affect the decisions of investors and other capital providers. Companies do not need to report on every ESG topic — only those that are genuinely material to their specific business, industry, and operating context.

This is why conducting a proper materiality assessment is one of the most critical first steps in your IFRS S1 compliance journey.

Where to Start: Building Your IFRS S1 Disclosure Framework

For most Group 2 PLCs, IFRS S1 compliance involves significant internal work. You will need to: appoint board-level sustainability oversight, conduct a materiality assessment to identify relevant topics, build data collection processes for your chosen metrics, document your risk management approach in relation to sustainability, and set measurable targets.

None of this happens overnight. Companies that begin now will have a clear advantage over those who wait.
