<p>This article explores the transformative potential of legal pathways and societal struggles to conserve biodiversity and achieve sustainability transformations toward multi-species justice. Exploring contemporary discourse on sustainability transformations, including emerging attention to relationality and critical perspectives, we analyse a range of legal instruments and measures to assess their transformative potential drawing upon their capacity to overcome rigid Cartesian dichotomies between humans and nature, to challenge capitalist accumulation imperatives and hence to contribute to a new societal sustainability goal of pluriversal, multi-species justice. Ranging from mainstream approaches in existing biodiversity and environmental instruments and supply chain instruments, such as environmental and deforestation due diligence, to newly emerging, more radical propositions of Rights of Nature, Ecocide and Restorative Justice, we review existing literature and empirical cases to interrogate and reflect upon their transformative potential, and to identify potentially effective combinations of socio-legal pathways.</p>
