Developed in partnership with IFC and with support from the Swiss State Secretariat for Economic Affairs (SECO), this Model Guidance provides exchanges and regulatory authorities with a structured template to develop guidance for directors on overseeing sustainability-related financial disclosures aligned with the IFRS Sustainability Disclosure Standards. Complementing the SSE's Model Guidance on Sustainability-Related Financial Disclosures, this publication addresses the distinct governance and oversight role of boards, and is designed to be freely copied and adapted for local market circumstances. The guidance provides directors with a practical four-step framework — Understand, Align, Oversee, Communicate — covering how to integrate sustainability into strategic decision-making, set parameters for risk management, build strong governance structures, and assess the credibility and quality of disclosures. It has been developed in alignment with the IFRS Sustainability Disclosure Principles, the Guiding Principles for Climate and Nature Governance and the IFC Corporate Governance Methodology, and includes board questions, best practice indicators, and annexes on key terminology, materiality, and alignment with other sustainability reporting frameworks including ESRS, GRI, SASB, and TCFD.
