Drivers of green supply management performance: Evidence from Germany

Five potential drivers of green supply management performance were identified in the literature review: green supply management capabilities, the strategic level of the purchasing department, the level of environmental commitment, the degree of green supplier assessment, and the degree of green collaboration with suppliers. These constructs were used to form a structural model explaining the environmental performance and the purchasing performance. The model was analysed with SmartPLS 2.0 using data collected among German purchasers. The results suggest that the degree of green supplier assessment and the level of green collaboration exert direct influence on environmental performance. These two practices are driven by the strategic level of the purchasing department and the level of environmental commitment of the firm. Whereas commitment influences green assessment directly, the impact of commitment on green collaboration is mediated by the capabilities of the purchasing department. Furthermore, the results show that environmental performance has a positive impact on purchasing performance.
