Under the growing environmental pressure and concern, organizations invest in information technologies for analytics and decision support in environmental sustainability management. Specifically, organizations should ensure the proper utilization of green information systems (IS) to achieve appropriate environmental outcomes. Otherwise, green IS becomes a non-performing asset, making it a low priority in organizations’ sustainability plans and strategies. This study anchors to the operant resources hierarchy perspectives and investigates how green IS relevant capabilities build on each other for environmental performance. With a matched dataset of 73 organizations from multiple sources, this study tests the effects of green support and information assurance on the relationship between green IS capability and green performance. The findings indicate that as composite operant resources and interconnected operant resources, the interactions of green support, information assurance, and green IS capability can improve organizations’ green performance.
