The wood craft industry in Badung Regency, Bali, significantly contributes to export value, yet faces challenges in maintaining sustainability and competitiveness. This study aims to examine the role of green human resource management as a mediator in the relationship between green human capital, green structural capital, green relational capital, and competitive advantage in wood small and medium enterprises. Employing a quantitative approach with descriptive and associative methods, the study sampled 267 enterprises from a population of 804 using proportionate stratified random sampling.

These results underscore the critical integration of green human resource management and green intellectual capital to achieve sustainable competitive advantage in the wood small and medium enterprise sector. The study highlights the strategic importance of aligning human resource practices with environmental goals to enhance efficiency, innovation, and market reputation, ensuring long-term sustainability and competitiveness.
