This article examines the diversity of opinions that exists within the ENGO community regarding their diagnoses of environmental problems and their preferred solutions to them. It provides a conceptual framework that consists of two components: values and governance approaches. Different values include ecological sustainability, distributive equity and economic efficiency. Governance approaches target states, international regimes, communities and markets as alternative loci for institutional solutions to environmental problems. The framework is used to illuminate salient patterns of conflict and coalitional behavior and to project future trends in global environmental politics.
