Awareness of environmental sustainability and ecological issues is growing, and different industry sectors are seeking ways to address them effectively. The Information Systems (IS) community is in a position to make a significant contribution to environmental efforts, not only by mitigating its own impact, but also by guiding the activities of other communities. To support environmental efforts, or to become more ―Green‖, several Green fields and research streams have emerged. Previous Green IT research focused on mitigating and reducing the impact of IT production and manufacturing, whereas Green IS research has the ability to re-design modern activities to support environmental efforts. This abstract reviews the state-of-the-art of Green IS research, and lists categories of IS solutions for environmental issues. A major contribution of this abstract is a suggested research agenda for Green IS.
