Environmental governance may be distinguished from environmental management by the implication that, in the former, some form of participatory process is involved. Here, the focus is upon the potential for women's movements and networks to influence the principles and practices of global environmental governance (GEG). It is contended that, in principle, women are uniquely placed to oppose the dominant norms informing GEG; and that women's participation would, in consequence, be crucial to the achievement of equitable and environmentally sound forms of governance. In practice, however, a number of factors combine to create divisions between women, and hence to impede transnational mobilization by women around environmental issues. This article examines these issues.
