Evaluation model for the sustainable use of information technology

Research indicates that 2% of these emissions are caused by the information technology sector. The raise of ICT usage leads to the increase of energy consumption leading to a movement towards Green IT. While some companies are defending that sustainable practices are outside of their boundaries, others are taking green initiatives as a business value. This paper presents a decision model to support companies for the use of sustainable Information Technology, combining Fuzzy AHP and TOPSIS. Three cases studies were conducted in order to validate the applicability of the model. The perception of companies indicates that human behavior is the most important criteria for improving green usage of IT, and the sub-criteria related to prevent unnecessary printing of documents and concern about recycling obtaining the highest weights.
