The emergence of sustainable design has brought attention to the consideration of human behavior in creating environmentally-friendly operations. This study examines the role of the Theory of Planned Behavior (TPB) and the Value-Identity-Personal Norm (VIP) model in shaping employee green behavior (EGB) and explores how green human resource management (GHRM) practices impact EGB. Based on a review of 40 scholarly articles, the study proposes a conceptual model that integrates individual-level constructs from TPB and VIP, and highlights GHRM as an antecedent of EGB at the organizational level, with psychological capital and organizational identity as mediators. The study suggests a multilevel approach to examining EGB, incorporating person-environment interaction, job performance, and motivation theory. Ultimately, the study aims to provide a research agenda that encourages further investigation of the topic.
