We have designed and developed the Personal Assessment Tool (PAT) to make users aware of the impact of their behavior on the environment and helping them to reduce it. PAT aims at promoting more sustainable print behavior in a corporate work environment. We have deployed and experimented PAT in our research center and describe this experiment along with preliminary findings and observations. From these findings we conclude that PAT definitely motivated the participating users to improve their print behavior. Nevertheless it also highlighted the constrained aspects of printing in a work environment calling for organizational changes of established work processes.
