A recent ACA Group (ACA) program examined institutional investors’ needs and expectations as to environmental, social and governance (ESG) investing and sustainable investing, as well as significant gaps that exist between that demand and what is currently available in the marketplace. The conversation revealed that not only do institutional investors want fund managers to generate more ESG data, but they also want significant improvements in the type of ESG data already provided to better facilitate portfolio monitoring. The discussion was moderated by Dan Carreno, associate director of client development at ACA, and featured Pooja Eppanapally, investment manager at Women of the World Endowment; Nancie Lynch, executive director at Richard and Nancy Marriott Family Foundations; Aaron Brachman, managing director at Washington Wealth Group of Steward Partners, and Luke Wilcox, partner and head of ACA Ethos. This article reviews the discussion and highlights key insights from the program.
