Methodological proposal to represent the local and global, direct and indirect environmental impacts of a service - Application to information technology.
type: Dataset
description: Services based on information technology in public and private sectors are growing. Therefore, the energy demand is more and more important to supply computer equipments within organizations and data-centers. So, environmental impacts of ICT are mostly “delocalised" and "invisible" from the end user.Gradually, the environmental issue takes place in the sector of information technology resulting in the new concept of the "Green IT". Nowadays, designers and users are seeking to assess the environmental impacts of information technology. In a context of environmental assessment for decision-making, the objective of this thesis is to assess the environmental impacts of devices of an organization. For this, we consider an approach to combine a product LCA approach with an inventory of data specific to a site.Literature searches have highlighted the specific and methodological needs in terms of impact assessment. Thus, a methodology for the expression of local and global environmental impacts associated with the production and use stages of information technology present within an organization is proposed. Applied in a partnership with a multinational society and validated by its application in a research laboratory, this methodology centralizes both generic data available in databases and specific data collected from users of the organization studied. This phase, key point of the methodology, provides firstly an inventory of present equipments and secondly the knowledge and comprehension of the actual behavior of users by the way of both a survey plus power and electric consumption measurements of representative equipments of the panel inventoried (use of acquisition boxes of values known as "energy meter").The environmental assessment approach developed in this work aims to highlight the environmental impact of the information technology’s equipments within an organization. One of the main results shows that the most environmental impacts are due to the production phase…
