Sustainability is without doubt one of the most important challenges of our time. How can we develop prosperity, without compromising the life of future generations? Information systems (IS) provide organizations with the ability to change and improve business processes to better support sustainable practices. Therefore, IS can make a contribution to the sustainable development of organizations. However, the organizational change aspects of Green IS are covered only marginally in the emerging literature. This paper aims to contribute the debate on Green IS, by highlighting the role of sustainability in the projects developing or implementing IS.
