Robert Klassen’s research emphasizes the linkages between operations and sustainability, including such areas as operational risk and social performance in supply chains. Recently, his research is focused on exploring policies, investments and practices within operations that reduce carbon emissions and mitigate the implications of climate change. He has over 60 refereed publications in such journals as Management Science, Journal of Operations Management, Academy of Management Journal, Production and Operations Management, and other leading management journals.
At Ivey, Klassen has taught the core Operations Management course in the MBA, MSc and EMBA programs, as well as electives in Sustainability, and Technology. He has coauthored two textbooks and has also written over three-dozen cases and simulation exercises in such topics as sustainability, operations strategy, and process analysis.
Dr. Klassen has served as co-Editor in Chief for the International Journal of Production and Operations Management. He recently completed a three-year term as co-Department Editor for the Sustainable Operations department of Production and Operations Management, and previously served in the same editorial role at the Journal of Operations Management. He also has served as the Division Chair for the Operations Management division of the Academy of Management.

Firms are increasingly blamed for environmental supply chain incidents revealed in media reports, which harms their reputations and economic returns. Therefore, firms may be increasingly motivated to publicly signal commitment to mitigating environmental harms and risks in their supply chains, such as by gaining membership in the Carbon Disclosure Project Supply Chain Program (CDP SCP). While CDP SCP membership may help to curtail subsequent media reports by successfully engaging suppliers in environmental impact mitigation (engagement mechanism), it could also amplify scrutiny by drawing unwanted attention (spotlight mechanism), prompting salient questions about membership outcomes. What is the relationship between CDP SCP membership and reported environmental supply chain incidents? What are the dominant mechanisms?
We address these questions using a novel dataset assembled from various archival sources including the CDP SCP, RepRisk, and FactSet. Our quasi-experimental design employs coarsened exact matching and a regression difference-in-differences model to compare outcomes across 124 CDP SCP members and 1,148 control firms, comprising a panel of 12,622 firm-year observations. We find strong and robust support for the net positive effect of CDP SCP membership on reported environmental supply chain incidents. Additional analyses reveal the underlying mechanisms: while CDP SCP membership causes positive changes in environmental performance at the supplier-level of analysis, it also attracts the attention of external stakeholders in ways that have been shown to be detrimental to buyers’ environmental reputation and economic returns.
