The International Court of Justice’s long-awaited Advisory Opinion on the Obligations of States in respect of Climate Change embeds important principles of international human rights law. It confirms that people may be entitled to international protection – that is, as refugees or beneficiaries of complementary protection – where the effects of climate change expose them to life-threatening risks. It also affirms that even if a State’s population and territory were to decline on account of sea-level rise, the State would continue to exist. Finally, by affirming the binding obligations of climate change treaties and the obligation of States to cooperate in the context of climate change, the Advisory Opinion potentially strengthens the case for more climate adaptation and loss and damage funding, including to support people to stay in place or to move elsewhere in a safe and dignified manner.
