ABSTRACT In Justice for People on the Move, Gillian Brock develops a promising, original account of migration justice. In her view, states have a robust (though conditional) right to self-determination, which includes a reasonably strong right to regulate migration. However, in order for these rights to be justified, three legitimacy requirements must be met. Most obviously, states must respect the human rights of their own citizens and the international state system itself must be legitimate. This latter condition also requires states to do their part in sustaining a justified state system, which includes helping to alleviate ‘legitimacy gaps,’ including significant human rights violations in other states. Brock uses this framework to address several pressing migration-related policy issues, including Muslim bans, the deportation of unauthorized migrants, temporary labour migration, and refugee protection. However, one topic is notably absent from her analysis: climate-related displacement. Some theorists insist that climate change migrants should not be considered refugees because they do not fit the standard definition of a refugee. In particular, climate migrants were displaced by droughts, floods, storms, or sea level rise rather than by war or persecution, and many are able to remain in their homes at present but will be forced to relocate at some point in the future. This paper explores the implications of Brock’s theory of migration justice for climate migration. I suggest that although her approach to refugee protection may initially appear to exclude climate migrants, her understanding of the right to self-determination yields strong obligations to assist them. I take this to be a strength of her framework, which makes an important, albeit indirect, contribution to current debates on climate change migration.
