Abstract

corporate sustainability environmental disclosures environmental violations greenwashing sustainability-focused mutual funds
This study examines the impact of corporate greenwashing on the investment behavior of sustainability-focused mutual funds. Greenwashing is defined as the discrepancy between a firm’s overly positive environmental disclosures and its actual environmental performance. I find that greenwashing firms tend to disclose less specific and quantitative information while using more complex language. Additionally, sustainability-focused mutual funds are less likely to hold greenwashing firms and more likely to divest when greenwashing is publicly revealed. Divested capital is reallocated to firms with better environmental performance. The negative association between greenwashing and mutual fund investment is most pronounced among firms with strong financial performance, high consumer visibility, and greater regulatory exposure. Overall, this study provides evidence that sustainability-focused mutual funds play an important role in promoting corporate sustainability by disciplining firms for misleading environmental claims.
