A review of empirical studies on proenvironmental behaviors in organizational contexts is presented. Twenty-one studies met the inclusion criteria. Quantitative effect sizes were compared where statistics were available and research designs were comparable. Characteristics of the dependent variable and the targeted organizational (sub)populations were systematically examined. With respect to individual-specific determinants, the results show relatively consistent effects for attitudinal determinants and past behavior. For organization-specific influences, management and physical facilitation were frequently significant. Findings related to other factors are less conclusive. Given the available evidence and feasibility considerations, it is recommended that interventions focus on physical facilitation, tailored persuasive communication, and active engagement of middle management. It is further recommended that future research integrates the analysis of individual and organizational determinants.
