[Résumé aussi en Français / Resumen también en español] EJOs (environmental justice organizations) and their networks have introduced several concepts to political ecology that have also been taken up by academics and policy makers. In this paper, we explain the contexts in which such notions have arisen, providing definitions of a wide array of concepts and slogans related to environmental inequities and sustainability, and explore the connections and relations between them. These concepts include: environmental justice, ecological debt, popular epidemiology, environmental racism, climate justice, environmentalism of the poor, water justice, biopiracy, food sovereignty, "green deserts", "peasant agriculture cools downs the Earth", land grabbing, Ogonization and Yasunization, resource caps, corporate accountability, ecocide, and indigenous territorial rights...[refers to Chevron, Texaco, Keystone (part of Thor Industries), BP, Dole, Umicore, Bechtel, Edison, Abengoa, Vale, Eskom]
