Sustainable procurement is increasingly on the agenda for purchasing and supply managers seeking to demonstrate corporate social responsibility in their supply chains. In this paper, we identify trends in the literature and establish that this is a burgeoning field. We identify methodological challenges and research gaps to guide future research. We propose a sustainable procurement framework to help structure future research across supply chains. Finally, we introduce each of the papers in the special issue, and identify what makes them stand out as making a novel contribution to research in the field.
