This Article traces how policy reversals in the first years of the Trump Administration implicate protections for diverse, low-income communities in the context of environmental pollution and climate change. The environmental justice movement has drawn critical attention to the persistent inequality in exposure to environmental harms, tracking racial and income lines. As a result of decades of advocacy, environmental justice has become an established, if not realized, principle in environmental law. Shifting positions under the Trump Administration now undermine this progress. To illustrate, this Article uses three exemplary contexts—agency transition, environmental law implementation, and international relations on climate change—to outline the impacts of reversing course on environmental justice.
