Despite increasing emphasis on corporate sustainability and green IS, empirical research on the relationships between specific green IS artifacts and intended outcomes (such as various resource consumption) are relatively scant. In addition, research is silent on the firm-specific factors that could influence the benefits from such artifacts. This paper seeks to fill this research gap by examining the relationship between carbon management system (CMS) and energy consumption. The paper also explores the role of the environmental management system (EMS) and human capital development (HCD) in influencing the relationship between CMS and energy consumption. The study utilizes data from secondary sources and proprietary databases. Findings from this study empirically demonstrate the environmental value of specific green IS artifacts and the role of facilitating factors.
