This Article outlines a role that human rights organizations in the United States and elsewhere can play in linking environmentally irresponsible conduct by governments and corporations to the violation of basic human rights. In addition, this Article identifies rights-based remedies for those violations. The goal is neither to assert a new right to a clean (or cooler) environment nor to prescribe specific climate change policies to governments or others. However, climate change and related environmental decisions made by governmental and corporate authorities must now take into account both procedural and substantive human rights and the impact of those decisions on the world’s poor. For the same reason, organizations committed to overcoming poverty, defending the environment, and protecting human rights should revise their tendency to view challenges, in developing nations and elsewhere, through a single lens and should pursue, either together or on parallel paths, an integrated vision of justice that takes into account economic equity, human rights, and respect for the natural and urban environment. Many U.S. human rights organizations have also ignored or treated as background the growing numbers of people living or dying in extreme poverty in the developing world. Yet climate change is certain to exacerbate the severe environmental and economic conditions already faced by billions of people. These conditions contribute to widespread violations of civil, political, economic, social, and cultural rights that are the central concern of human rights organizations.
