The study aimed to examine the mediating role of environment management practices between green intellectual capital and green human resource management. A positivism philosophy, explanatory research design and quantitative research methodology was employed for collecting data from 125 ready-made garment manufacturing firms in Bangladesh. Smart-PLS 3.2.9 was used to observe the proposed relationship. The results indicated that environment management practice has a significant influence in the relationship between green human capital and green human resource management, and green relational capital and green human resource management. Surprisingly, environment management practice does not play any significant mediating role in between green structural capital and green human resource management. In addition, green human capital and green relational capital has a significant direct influence on green human resource management. However, green structural capital does not have any significant direct impact on green human resource management.
