Knowing the right questions to ask management on material environmental, social, and governance issues has become an important part of a board’s role. Five years ago, our research at NYU Stern Center for Sustainable Business found U.S. public boards were not fit for this purpose — very few had the background and credentials necessary to provide oversight of  ESG topics such as climate, employee welfare, financial hygiene, and cybersecurity. Today, we find that while boards are still woefully underprepared in certain areas, there has been some important progress.
