The engagement of firms in environmental collaborations has become a ubiquitous phenomenon in today’s business landscape. Yet much of the research to date is fragmented across multiple disciplines and lacks a clear framework to support future study. The authors consolidate and synthesize existing contributions into a conceptual map comprised of antecedents, consequences, and contingencies to better understand environmental collaborations. This map offers a perspective on how firms develop strategies, structures, and capabilities to manage and balance environmental and economic performance and increasing demands for environmental sustainability from multiple stakeholders and society. The authors then highlight existing gaps in the extant literature and outline a future research agenda, including key questions and issues needing additional study.
