Related with this issue, recently many organizations and companies are starting to implement the "Green Business" policy pattern, companies are paying attention to the importance of integrating Environmental management and Human Resource management such as the implementation of "Green HRM" or green human resource management. The Ministry of Finance and Bank Mandiri are the two government agencies that have pioneered the implementation of GHRM in human resources management and  environment in Indonesia. This research was conducted in both agencies and aims to analyze the impact of implementation of these policies on environmental friendly (green) behavior in increasing organizational commitment. This research involved with 209 managerial employees as respondents who were obtained by convenience sampling technique. The data were collected using the g-form and the tests on the model were applied and met the model fit requirements. These findings proved that not all GHRM dimensions have a significant effect on green behavior and organizational commitment.

However, the green behavior was significantly mediates the effect of GHRM training and development in increasing organizational commitment.
