The impact of environmental technologies on manufacturing performance

Management of the natural environment is becoming an increasingly important issue to manufacturing firms, yet their managers are also challenged to im plement changes that improve competitiveness. To meet this challenge, a new construct grounded in the resource-based view of the firm and manufacturin g strategy has been developed: the environmental technology portfolio. The composition of a plant's portfolio-the pattern of its investment in environ mental technologies in manufacturing over time-was found to significantly a ffect both manufacturing and environmental performance for a sample of manu facturing plants.
