Global warming and other environmental issues have become a major focus on the global agenda. Indonesia, as a developing country with a significant industrial sector including the electricity industry, faces significant challenges related to carbon emissions and environmental impacts. This study aims to investigate the influence of Green Human Resource Management (Green HRM) and Green Innovation on company Environmental Performance, considering the role of Employee Green Behavior as a mediator at PT. PLN Distribution Jakarta Raya. The research adopts a quantitative descriptive approach with a cross-sectional design. The research sample consists of employees from PT. PLN Distribution Jakarta Raya selected through purposive sampling. Data were collected via questionnaires and analyzed using Structural Equation Modeling (SEM) with Partial Least Squares (PLS). The analysis results indicate that Green Human Resource Management (H1) significantly and positively influences Employee Green Behavior and Environmental Performance at PT. PLN Distribution Jakarta Raya. Furthermore, Green Innovation also has a significant positive effect on employees' green behavior and Environmental Performance in the company. Employee Green Behavior has been shown to contribute significantly to Environmental Performance. However, the influence of Green Innovation on Environmental Performance is not significant. Moreover, Employee Green Behavior can act as a mediator linking the influence of Green Human Resource Management on Environmental Performance, but not in the case of Green Innovation. This study contributes to the fields of environmental management and human resources by highlighting the importance of integrative strategies to achieve better Environmental Performance in companies. The next step involves implementing these practices on a broader scale to support environmental sustainability in the future.
