Assessing green innovation in supply chains: a systematic review based on causal mechanisms framework

PurposeThere have been several reviews of green, ecological and sustainable innovations, but a thorough assessment of green innovation (GI)'s mechanisms in a supply chain setting has not been attempted yet. The purpose of this paper is to review how GI was investigated in supply chains through the lens of a multilevel framework of innovation mechanisms.Design/methodology/approachThe authors provide a comprehensive assessment of prior studies using a systematic literature review approach and content analysis of 136 papers identified from the Web of Science Core Collection database.FindingsCurrent literature on green innovation supply chains (GISC) has been categorized according to three main causal mechanisms: situational, action-formation and transformational mechanisms. Three different levels of analysis were considered for the three mechanisms: macro, meso and micro. In addition, the authors have also assessed the value creation and appropriation outcomes of GI. The authors identified relevant research gaps in the extant literature and a set of propositions that may guide future research in this area.Research limitations/implicationsThis review provides a novel perspective on GISC based on a multilevel theoretical framework of mechanisms.Practical implicationsThe causal mechanisms assessment of GISC can be adopted by organizations to convince their SC partners to engage in collaborative and more ambitious initiatives in the field.Social implicationsThe findings of this review could serve as an argument for more encompassing and ambitious GISC initiatives which can be of benefit to society.Originality/valueA thorough assessment of the interacting mechanisms in GISC has not been attempted before. The authors identify gaps in current literature and provide several propositions for further research avenues based on causal mechanisms framework.
