Sustainable procurement has become an important agenda for both private and public organisations across the globe and plays an important role in the push for sustainable development. The execution of the entire procurement process must incorporate sustainability principles in light of recent trends in the field of procurement. With a focus on how environmental issues and issues relating to other parts of the sustainable development pillars (society and economy) can be included in the procurement activities, procurement organizations are becoming more significantly involved in formulating and executing sustainable procurement policies. The main objective of the study is to examine the effect of sustainable procurement practice on social and environmental performance of firm, and the moderating role of top management support. The target population of the research was the various organizations in the New Juabeng Municipality of the Eastern region of Ghana.
