This project focuses on the consistency and the reasons linked with some of the Environmental behaviors of EPFL community. A statistical and segmentation analysis will be performed, at first to investigate the consistency between people's behaviors and then to investigate the factors that influence the realization or not of these behaviors. This environmento-sociologic work will bring informations concerning EPFL's users, informations that could be reused in order to analyze new strategies for having a green campus and to adopt the best decisions for convincing people to adopt a more eco-friendly behavior.
