Human rights enjoy a presumption of inviolability that at least arguably "trumps" other public goods. To the extent that sustainable development has become bogged down in conventional economic thinking, a human rights analysis may offer a way to cut through "business-as-usual" thinking. International human rights offers society's most vulnerable inhabitants an additional route of legal recourse for environmental harms, one that protects them even in the face of state law to the contrary. As such, human rights can create a space for developing innovative solutions to thorny social problems like environmental injustice, particularly the unequal distribution of environmental harms across society. Because the human right to a healthy environment is "claimed not granted," there is value in"'examining what environmental activists actually do on the ground, and how they shape their environmental claims. This principle remains true even for actors who do not make human rights claims, and do not even view themselves as human rights actors. This article examines one such situation, using the successful campaign to shut the Charles A. Poletti Power Plant to glean human rights and environmental advocacy lessons for those who would vindicate environmental rights in an unequal world.
