Abstract

We estimate financial institutions' portfolio tilts that relate to stocks' environmental, social, and governance (ESG) characteristics. In 2021, ESG-related tilts total 6% of the investment industry's assets and average nearly 25% of institutions' total portfolio tilts. ESG tilts are larger for less-volatile stocks and for institutions with smaller size and greater active share, consistent with our theoretical predictions. Significant ESG tilts arise from the choice of stocks held and, especially, the weights on stocks held. The largest institutions tilt increasingly toward green stocks, while other institutions and households tilt increasingly brown. UNPRI signatories and European institutions tilt greener, banks browner.

Keywords: ESG, sustainable investing, portfolio tilt
