1 Introduction*
On 12 December 2022, the Commission of Small Island States on Climate Change and International Law (COSIS) submitted a request to the International Tribunal for the Law of the Sea (ITLOS) to render an advisory opinion. In its request, COSIS asked ITLOS to clarify ‘the specific obligations of State Parties to the United Nations Convention on the Law of the Sea [UNCLOS] […] to prevent, reduce and control pollution of the marine environment in relation to the deleterious effects that result or are likely to result from climate change’ as well as ‘to protect and preserve the marine environment in relation to climate change impacts’ more broadly (Request for an Advisory Opinion).
