The type of research called causal associative research is quantitative-based. The population in this study is employees of Bank BUMN Selayar Regency, namely: Bank Rakyat Indonesia, Bank Negara Indonesia and Bank Mandiri where the number of population members is unknown, respondents determined by convenience sampling technique with a total of 96 respondents. The results of the study found that green training, green performance management, and green employee involvement were proven to have a positive and significant effect on organizational citizenship behavior for the environment (OCBE), while green rewards did not have a significant effect. These findings indicate that employees' voluntary behavior in supporting sustainability is more influenced by aspects of learning, management systems, and active engagement, rather than just incentives or rewards provided by organizations.Keywords: Green Training; Green Performance Management; Green Employee Involvement; Organizational Citizenship Behavior for The Environment
