This document outlines an ICT tool to support more sustainable use of print and digital devices. It discusses the scientific basis of life cycle assessments that were conducted on production, use, and disposal of ICT devices and printing. It also describes the implementation and design of the tool, including calculations, a user input form, and database. Finally, it provides example scenarios comparing the environmental impacts of printing a book or bank statement versus using digital alternatives like a tablet or computer. The presentation ends with information for questions about the environmental science.
