Great day of discussions at the Wharton Initiative for Global Environmental Leadership. Talks addressed the financial, technical, market, and developmental challenges and opportunities which sit at the foundation of a transition to a sustainable circular economy. Not surprisingly, data seemed to be the common thread that weaved its way through most of the day’s talks. If ESG ratings and methodologies are going to carry any real meaning, both from the operational perspective on the part of corporations to the financial incentives supporting the search for investment opportunities, it is imperative to start by focusing on many the topics discussed here today. Gary Survis did a fantastic job moderating the diverse and thought-provoking panels, and as always a huge thanks goes out to Joanne Spigonardo for organizing a wonderful and collaborative series of discussions. Much more to be done!
