The purpose of this study is to explore the relationship between green human resource management (HRM) practices, including Green recruitment and selection, Green training and development, and Green rewards, and environmental performance in Jordanian health service organization. The research hypotheses are tested by means of a questionnaire survey carried out among health service organizations in Jordan between April and May 2018. Our design choice to focus on a single sector was because of our intention to diminish the confounding effects of non- controllable factors in our research study, such as legislative, culture, and economical contexts. The results show a moderate implementation of Green HRM in Jordanian hospitals, the strongest correlation was with recruitment and selection while the weakest correlation was with training and development. Statistical positive association also was indicated between the three HRM practices and environmental performance.
