PurposeSupply chain (SC) managers influence firms in incorporating green behavior throughout the value chain in functions such as purchasing, production, distribution and transportation. In this study, we aim to understand the antecedents of pro-environmental behavior (PEB) in SC managers.Design/methodology/approachWe develop a research model hypothesizing a direct role of SC managers' private green behaviors, subjective norms, personal and organizational barriers as factors influencing the manager's pro-environmental intentions. We also analyze the impact of these intentions on actual behavior. We surveyed managers working in the SC of manufacturing firms in a developing country and tested the research model using structural equation modeling.FindingsOur results indicate that SC managers' personal barriers significantly influence intentions to act pro-environmentally and these intentions then predict their actual behavior. However, SC managers' private green behaviors do not spill over to their workplace. Furthermore, the study shows that organizational-level barriers and subjective norms may reverse green intentions.Originality/valueThis study contributes to the research literature by identifying the role of organizational, personal and social factors in modifying the SC managers' intentions. It provides useful insights into how these factors affect the behavior of SC managers. Thus, we extend prior work in the area of PEB to the SC environment.
