Beyond «Climate Refugees»: Rethinking International Protection for Environmentally Displaced Persons

Climate change and environmental degradation are increasingly recognized as major drivers of human mobility, operating through both sudden-onset disasters and slow-onset processes such as sea-level rise, desertification and resource scarcity. Although estimates vary widely, projections suggest that millions of people may become displaced by 2050 because of climate change, predominantly within their own countries but also across international borders. This article examines the emerging phenomenon of “environmental migration” against the backdrop of international refugee law and broader human rights frameworks. It first maps the diverse environmental scenarios that trigger displacement before analyzing the existing international legal landscape. Particular attention is paid to the contested terminology surrounding “climate refugees”, “environmental migrants” and “environmentally displaced persons” and to the protection gaps that arise from current categorizations. This article argues that, while existing norms on human rights, disaster risk reduction and internal displacement offer partial safeguards, they do not provide coherent legal status or systematic protection for people displaced across borders by climate-related harms. It concludes that climate-related displacement should be addressed through a combination of evolving human rights-based climate litigation, enhanced use of existing instruments and the progressive elaboration of specific normative frameworks.
