The purpose of this article is to address the future of associative research aiming at building a partnership of knowledge, related in this article to environmental justice issues. The development of a new web, a "hermeneutic" web, makes us consider how possible it is to develop a science-society interface based on a political model of dialogue on knowledge. The ePLANETe knowledge portal on environmental education, ecological economics and sustainability anticipates such developments. Three tools are presented in this article, in order to mobilize actors and knowledge to build a collective representation of socio-environmental conflicts, to deliberate around social choice, and to make more accurate environmental governance.
