Manufacturers around the globe are implementing socially responsible practices in Mtheir plants to comply with government policies, to create more value or for socially conscious reasons. Research has examined some aspects of the implementation of socially responsible practices, but little is known about the general level of implementation of such practices. Also, only a few studies have examined the degree to which such practices contribute to bottom-line manufacturing performance, or whether such practices differ in various regions around the world. The present study used a database of manufacturing plants to explore whether the practices of pollution prevention, waste reduction, recycling of materials and employee health and safety were related to indicators of manufacturing performance and competitiveness. Results showed that the use of socially responsible manufacturing practices was related to indicators surrounding the speed of delivery. Implications of the results for future research are discussed.
