Drawing upon the resource-based view and the situated learning theory, this study examined the effect of green human resource management (HRM) practices on the firm environmental innovativeness. The moderating role of organizational innovative culture on the relationship between green HRM and firm environmental innovativeness was also assessed. A survey of 212 furniture manufacturing companies in Malaysia was analyzed using structural equation modeling. Results from the data analysis suggest that green HRM practices are positively associated with the firm environmental innovativeness. The positive effect of green training and green compensation on firm environmental innovativeness was found to be increased by moderating the role of organizational innovative culture. The present study clarifies key green HRM practices that can assist the environmental innovativeness in Malaysian furniture manufacturing firms and advances related research by proposing and examining an overarching model to enlighten such synergies and the moderating role of organizational innovative culture. The findings further extend the scope of green HRM research to promote innovation in the manufacturing firms. The theoretical and practical implications of green HRM are presented to enhance the environmental innovativeness.
