Motivating Green Knowledge Behavior by Mindfulness Leadership in Engineering Design: The Role of Moral Identity

The green behaviors of engineering project designers can improve the green performance of engineering projects. Moral factors are likely to influence designers’ behavior related to green design. Therefore, this study takes mindfulness leadership as a new antecedent of green behavior and explores how mindfulness leadership influences the green behaviors of designers. Based on social cognitive theory, this study proposes that mindfulness leadership stimulates the designers to exhibit green behaviors. Then, this study used a survey design and adopted partial least squares structural equation modeling to examine the hypotheses. The results indicate that mindfulness leadership is positively associated with green voice behavior (β = 0.313), green knowledge-sharing behavior (β = 0.281), and green helping behavior (β = 0.353). Moreover, moral identity mediates the main effect (βa = 0.131, βb = 0.147, βc = 0.169). These quantitative findings substantiate that mindfulness leadership can effectively motivate designers to provide eco-conscious solutions, share sustainability knowledge, and collaborate on green improvements. The study equips project managers with evidence-based strategies to cultivate moral identity and leadership practices that systematically enhance environmental performance in engineering design contexts.
