As a party to the United Nations Convention on the Law of the Sea (UNCLOS), Timor-Leste participated in the International Tribunal on the Law of the Sea (ITLOS) Advisory Opinion on the obligations of states with respect to climate change. This was a historic advisory proceeding, in which the question of the obligation under UNCLOS to protect the marine environment from the deleterious impact of climate change was elucidated.
