<p>While previous research has emphasized the influence of various pressures on green supply chain integration, less emphasis has focused on the role of emotionally related factors such as passion. Grounded in a dualistic model of passion, this study investigates how environmental passion influences green supply chain integration through sustainable decision tradeoffs. It also examines the moderating role of resource bricolage between sustainability decision tradeoffs and green supply chain integration. Based on survey data from 329 Chinese manufacturers, we find that both harmonious and obsessive environmental passion positively influence three dimensions of green supply chain integration (i.e., green supplier, internal, and customer integration). The results also show that sustainability decision tradeoffs partially mediate the linkage between harmonious/obsessive environmental passion and three dimensions of green supply chain integration. Furthermore, resource bricolage is found to negatively moderate the relationship between sustainable decision tradeoffs and three dimensions of green supply chain integration. This research offers theoretical and practical insights on how environmental passion and sustainable decision tradeoffs can be leveraged to support green supply chain integration.</p>
