The sustainability committee and environmental disclosure: International evidence

HFRC Working Paper Series | Version 08/2023


Using a large set of firms from 35 countries over the 2010–2017 period, we find that the presence of a sustainability committee is positively associated with higher-quality environmental disclosure. This finding is robust to endogeneity and sample selection bias concerns. The sustainability committee effect is more pronounced when external environmental institutions are too weak to properly monitor corporate environmental disclosure. We also find that raising the quality of environmental disclosure leads to a lower cost of equity capital only for firms with sustainability committees in place. Our findings suggest that sustainability committees play an important role in facilitating and certifying corporate environmental disclosure.
