Join other senior executives at this exclusive Executive Roundtable to explore how global companies can effectively cascade sustainability goals throughout their value chains, what true collaboration looks like, and how to support suppliers with their own commitments and how to empower supplier responsiveness to critical data requests. Through candid, solutions-oriented group discussions, we’ll also examine best practices across industries, discuss tools that enable education and transparency, and learn how companies are preparing for evolving disclosure requirements.

Please note that this is an invitation-only event held under the Chatham House Rule. We kindly ask that if you are unable to attend and would like to transfer this invitation to another senior-level colleague, reach out to us beforehand.
