We review the sustainable operations management research published in the first 20 years of Manufacturing & Service Operations Management (M&SOM), and we outline our hopes for the next 20 years. This review provides a “big picture” overview of trends in the sustainable operations management research in M&SOM, along with an impact assessment both inside and outside the boundaries of operations management research. We provide a brief chronological survey of sustainable operations management publications in M&SOM, as well as a high-level citation analysis. Together, these analyses indicate that the topics studied in the sustainable operations management publications in M&SOM have largely followed some issues of business relevance and have made a substantial scholarly impact both inside and outside our field. We also propose a number of open research directions.
