This study investigates the relationship between directors’ foreign experience and corporate environmental disclosure in Chinese listed firms from 2009 to 2017. The research shows that directors with foreign experience have a positive and significant impact on corporate environmental disclosure. This effect is more pronounced in nonstate-owned enterprises, where directors have greater influence over managerial decisions. Additionally, the study suggests that in industries with high energy consumption, high pollution, or overcapacity, the positive effect can be further enhanced by having at least three directors with foreign experience or foreign experience members in the audit committee. The impact of experiential diversity on environmental disclosure is greater than that of board gender and independence diversity. The findings suggest that policymakers and firms prioritize the recruitment of directors with diverse experiences to improve their environmental disclosure practices.
