Responding to environmental challenges is a new manifestation of innovation for organizations, which enables firms to gain competitive advantages by conducting innovative activities for not only themselves, but also for the whole society. In this context, much attention has been paid to “green creativity.” However, few studies have explored the impact of green creativity from the perspective of interactions between individuals and organizational contexts. Therefore, we aimed to explain the variance in employees’ green creativity by examining three factors outside the organizational context: transformational leadership, green human resource management (GHRM), and individual factors including employees’ green passion. Drawing from the ability–motivation–opportunity theory, we found that transformational leaders can inspire employees’ green passion through influencing GHRM, and ultimately positively affect employees’ green creativity. Data collected from two sources (employees and human resources managers) in medical firms in northeast China at two time points demonstrated the important effects of transformational leadership, GHRM, and employees’ green passion on green creativity, thus offering new theoretical insights and practical suggestions.

Based on natural resource-based theory, we examined how firms’ environmental strategies and environmental reputation depended on their green human resource management and discretionary slack. From the perspective of human resource management, we hypothesized that proactive environmental strategy predicted firms’ environmental reputation through the mediation of green human resource management. We further proposed that slack resources, which can be used discretely by managers for environmental management, enhanced the hypothesized relationships. Using data from firms in environmentally sensitive industries in eastern China, we provided empirical support for our hypotheses. The findings highlight the vital roles played by managers and green human resource management in implementing firms’ environmental strategies and promoting firms’ environmental reputation.
