Using the natural resource - based perspective (NRBV) as our theoretical lens, green IS is conceptualized as comprising different dimensions of sustainability practices that can create competitive advantage for the organization. This study examine (i) the impact of adoption of green IS on organizational performance; (ii) the impact of the extent of adoption of green IS on organizational performance; and (iii) the impact of different dimensions of sustainability portfolio (pollution prevention, product stewardship, clean technologies and sustainability vision) on organizational performance. Data on green IS dimensions and performance measures of organizations are gathered from secondary sources. Results will indicate that if the adoption of green IS is positively associated with organizational performance. Further, we examine that among green IS organizations, do organizations with greater extent of adoption have better organizational performance. Finally, we examine the relationship between different sustainability dimensions and different measures of organizational performance. Findings from this study are expected to empirically demonstrate the business value of green IS.
