Today, the issue of corporate environmental practice has been discussed extensively in research and operation because the future of sustainability is at stake. Thus, this paper’s objectives are 1) to understand the corporate environmental practice and 2) to determine the key factors of successful corporate environmental practice. Data were gathered from semi-structured interviews with representatives from several prominent Public Listed Companies (PLCs) in Malaysia, which are the pioneer in this area. Findings from this study reveal that companies should have clear environmental guidelines, and most importantly enhanced data governance for greater corporate environmental practice. The conclusion discusses the continuous improvement in navigating and planning future research.
