This study investigates the prevalent issue of environmental injustice, where organizations tend to establish and operate high-polluting manufacturing facilities more frequently in communities of color than in predominantly white areas. This practice leads to significantly higher emissions of toxic chemicals, exposing minority communities to adverse health effects such as cancer. To address this injustice, we examine the impact of a firm governance reform – the appointment of a Chief Sustainability Officer (CSO).
Using data on the toxic releases of U.S. manufacturing facilities from 2000 to 2020 and a difference-in-differences research design we find that appointing a CSO can lead to a 20% reduction of toxic releases. This reduction is particularly notable in facilities located in underserved communities, thereby contributing to a decrease in environmental injustice. We also identify the implementation of toxic release source reduction activities as a potential mechanism behind these findings.
Our primary theoretical contribution is to demonstrate the potential usefulness of corporate governance reforms as a control mechanism for addressing environmental injustice, an issue that has proven challenging to regulate effectively. Additionally, we offer empirical evidence regarding the environmental impact of appointing a CSO, contributing to the ongoing debate on this topic.
