The aim of this paper is to investigate and map climate change discourses in legal spaces. We look at how issues concerning the injustice and human rights violations caused by climate change—and by mitigation and adaptation policies and strategies—are transformed and manifested in legal conflicts. The paper investigates ways in which climate change impacts are legalized, judicialized, and debated in relation to concrete conflicts about natural resources and environmental harm (which we refer to as conflicts over climate justice and sustainability). Today the law is in many ways “the new politics” in the sense that the legal field is expanding in social and political significance, not least in the contexts where other governance structures are weak.
