IFRS S1 & S2: A New Era in Sustainability Reporting

 At a Glance

• Alignment of reporting – IFRS S1 and S2 strengthen the connection between sustainability disclosures and traditional financial reporting.

• Enhanced transparency – Investors and stakeholders gain clearer insight into how companies manage sustainability and climate-related risks.

• Regulatory clarity needed – Clear guidance, materiality definitions, and phased implementation are critical for smooth adoption.

Introduction of IFRS S1 and S2

In June 2023, the International Sustainability Standards Board (ISSB) issued its first two standards:

• IFRS S1 – General Requirements for Disclosure of Sustainability-related Financial Information

• IFRS S2 – Climate-related Disclosures

These standards mark a significant milestone in capital markets by bringing global coherence to sustainability reporting. Backed by governments and regulators across more than 40 jurisdictions, they set the stage for enhanced consistency, comparability, and investor confidence worldwide.

Bridging Sustainability with Financial Outcomes

IFRS S1 expands beyond climate change to cover the broader spectrum of sustainability risks and opportunities. Entities must disclose:

• Governance and oversight of sustainability targets;

• Internal controls and processes for managing sustainability-related risks, and;

• Integration of sustainability considerations into overall strategy and risk management.

IFRS S2, effective for reporting periods beginning on or after 1 January 2024, requires disclosures on climate-related risks and opportunities. Built on the TCFD framework, the standard mandates reporting across four pillars: governance, strategy, risk management, and metrics & targets. A key feature is the requirement to disclose Scope 1, Scope 2, and material Scope 3 greenhouse gas emissions, offering a comprehensive picture of climate impact.

Together, these standards establish a structured framework linking sustainability factors to financial statements, allowing stakeholders to evaluate resilience, performance, and long-term value creation.

Implications for Businesses

The extent of change required will vary by sector and maturity of existing sustainability practices. Companies in carbon-intensive industries may need to undertake strategic reviews, including:

• Transitioning to renewable technologies;

• Optimizing resource usage, and;

• Embedding climate resilience in their business models.

Across industries, boards, audit committees, CFOs, and sustainability officers will face heightened accountability. Organizations will need to allocate resources for:

• Gap analysis and maturity assessments,

• Enhancement of internal controls and governance frameworks,

• Capacity building and training of finance and sustainability teams, and

• Engagement with regulators to ensure compliance.

Conclusion

IFRS S1 and S2 represent more than just compliance requirements — they provide an opportunity for organizations to align sustainability and financial performance, enhance stakeholder trust, and position themselves competitively in a rapidly evolving market.
