Green growth can be achieved through environmental sustainability which can be translated into workplace pro-environmental behavior at the individual level. Workplace Pro-environmental behavior refers to a range of actions directed toward the environment that includes all forms of voluntary or prescribed activities performed by individuals at work to protect the natural environment or enhance organisational green practices. Therefore, necessary efforts in identifying the key determinants of pro-environmental behavior among Malaysian public servants should be taken to realize Malaysia’s green growth achievement since public servants are the largest workforce in Malaysia. Moreover, studies on pro-environmental behavior among the Malaysian public servant is still limited. Hence, this study aimed to explore the determinants that influence workplace pro-environmental behavior (WPEB) based on systematic literature review and preliminary study. A comprehensive systematic literature review has been conducted to identify articles that empirically examined the determinants of employee pro-environmental behavior through the trusted SCOPUS databases sources. Next, a preliminary study was done to further evaluate and rank the importance of each determinant obtained from the systematic literature review conducted earlier in this study. A total of five key figures were chosen to participate in the preliminary study based on their experience and expertise and they were requested to evaluate the importance of each determinant of WPEB based on the experience of WPEB in their workplace setting. Overall analysis results from the mean value obtained from the preliminary study showed two individual environmental concern and environmental harmonious show a high level of mean score of 4.80. Likewise, environmental transformational leadership and perceived organization support toward environment achieved the highest mean score of 4.80 collectively represented organisational determinants.
