We intend to give an account of the privatization of global environmental governance through the monitoring of transnational multi-stakeholders initiatives for social and environmental regulation. These multi stakeholders initiatives have proliferated during these recent 10 years . Number of them have been institutionalized, following the example of forest certification FSC (Forest Stewardship Council), certification of the good practices halieutics (Marine Stewardship Council), standards of the organic farming carried by the IFOAM (International Federation off Organic Agriculture Movement… Most narratives on their rise and proliferation stress on the driving role of the multinational firms through blame avoidance strategy on one side; or on the increasing political weight of the social movements, which fight to embbed justice and environmental concerns civil society into global market. Our research aims to explore another explanatory framework, starting from the following assumptions: the rise of the devices of standardization hightlight the extension and the dissemination of market rationalities in the field of the environmental policies; in addition this neoliberal rationality is diffused by a managerial elite, composed of TNC, NGO and experts. To check these assumptions, the program declines 3 scientific tasks (T2, T3, T4) narrowly articulated and a task of coordination This proposal for a research positions in the axis set of themes 1 of the call to project, and mobilize a multi-field collective of 13 researchers.
