Strengthening Board Oversight of ISSB-aligned Sustainability Reporting: New Model Guidance and Board Workshop Launched

As sustainability reporting frameworks gain traction globally, attention is increasingly shifting from what companies disclose to how those disclosures are governed at the board level.

In response, the United Nations Sustainable Stock Exchanges (UN SSE) initiative, in partnership with IFC, the IFRS Foundation, and the Chapter Zero Alliance, has launched a Model Guidance for Board-Level Oversight of ISSB-aligned sustainability reporting, alongside a pilot interactive training – together providing a practical framework to help strengthen board oversight capacity.

Translating standards into boardroom practice
With over 40 jurisdictions worldwide moving toward adoption of IFRS Sustainability Disclosure Standards (IFRS S1 and S2), boards are playing an increasingly central role in ensuring that sustainability reporting is credible, decision-useful, and aligned with strategy and risk management.

The newly launched Model Guidance responds directly to this need, offering a structured and practical framework for directors to oversee sustainability-related financial disclosures.
At its core, the guidance outlines a four-step approach for boards:

• Understand the implications of sustainability-related risks and opportunities
• Align governance structures, risk management, and internal processes
• Oversee implementation, including controls and reporting systems
• Communicate disclosures that are clear and credible

Rather than introducing new requirements, the guidance helps boards operationalize existing standards—bridging the gap between technical reporting frameworks and governance responsibilities.

From framework to application
Building on this foundation, IFC and UN SSE have already begun translating the guidance into practice. On March 31, 2026, a pilot interactive workshop on Board Oversight of ISSB-Aligned Reporting brought together board members, regulators, and market participants from across regions.
The workshop focused on equipping participants with the tools needed to apply the Model Guidance in real-world settings—covering areas such as governance structures, materiality, internal controls, and disclosure quality.
Importantly, the session moved beyond compliance to emphasize the role of boards in driving strategic integration of sustainability considerations, reinforcing that high-quality reporting starts with effective oversight.
This pilot is part of a broader effort to scale capacity building through the UN SSE Academy and IFC’s Beyond the Balance Sheet (BBS) program, supporting markets in advancing from awareness to implementation.

IFC perspective
IFC played a central role in both the development of the Model Guidance and its practical rollout. As noted by Charles (Chuck) Canfield, Corporate Governance Manager at IFC:
“IFC has long recognized that strong corporate governance is the foundation of sustainable and resilient capital markets. This guidance, developed through our continued partnership with the UN Sustainable Stock Exchanges Initiative, provides directors with a structured and actionable way to fulfil that responsibility. We are proud to support this work and to see it translate directly into practical tools that markets can adopt and adapt.”
This reflects IFC’s broader approach: positioning sustainability disclosure as a core governance issue, requiring the same rigor, accountability, and oversight as financial reporting.

Building a global ecosystem
Together, the Model Guidance and its associated training initiatives reflect a broader evolution in the sustainability reporting landscape. Following several years of rapid development of disclosure standards, the priority is now shifting to embedding these standards into corporate governance systems and board processes.

Through its collaboration with UN SSE and the IFRS Foundation, IFC has supported training efforts reaching thousands of participants across more than 35 markets, helping build the foundation for ISSB adoption and implementation.

Relevance for Beyond the Balance Sheet
These initiatives are closely aligned with IFC’s Beyond the Balance Sheet (BBS) program, which supports the adoption and operationalization of sustainability reporting frameworks globally. By linking global standards (ISSB) with practical governance tools (Model Guidance) and capacity-building initiatives (workshops and training), BBS is helping create a more complete and functional reporting ecosystem.
This integrated approach is particularly relevant for emerging markets, where strengthening board oversight, institutional capacity, and reporting practices is critical to ensuring that sustainability disclosures are both credible and decision-useful.

Looking ahead
As sustainability reporting continues to mature, the expectations placed on boards are evolving.
Directors are increasingly required to oversee sustainability risks alongside financial risks and ensure the integrity and usefulness of disclosures. The combination of clear guidance and hands-on training marks an important step toward this goal—supporting boards in moving from awareness to action, and from compliance to effective governance.
