Investments that focus on ESG (environmental, social, and governance) factors have grown in popularity in recent years. In 2021, ESG —or sustainable — funds in the U.S. took in $70 billion in net flows, up 35% from 2020. While interest in ESG has risen, more education is needed, according to a recent study. Among those surveyed, 26% hold an ESG investment, and 46% said they were interested in ESG. In addition, 35% said they were not interested. Of those, more than half said they were not interested because they don’t understand enough about these investments.
