<p>This study investigates how the presence of Sustainability Committees correlates with corporate environmental performance, specifically as measured by green investments. Using a unique firm-level database, we explore whether firms with Sustainability Committees outperform other firms in terms of green investments. Namely, we define performance as the likelihood of a firm: (i) having undertaken green investments; (ii) planning future green investments; and (iii) perceiving such investments as competitiveness-enhancing. To address potential endogeneity concerns, we employ an instrumental variables approach. Our results suggest that the presence of a Sustainability Committee is associated with stronger realized and planned green investments by firms. Moreover, the empirical results indicate that its presence is associated with viewing green investments as a strategic driver of competitiveness rather than a mere response to regulatory compliance. Our findings contribute novel insights to this field and could be valuable for board members, managers, investors, and policymakers aiming to advance sustainable development strategies.</p>
