Understanding the ITLOS Advisory Opinion on Climate Change

Understanding the ITLOS Advisory Opinion on Climate Change

On May 21, 2024, a pivotal moment in international climate change litigation occurred when the International Tribunal for the Law of the Sea (ITLOS) provided an advisory opinion. This opinion was sought by the Commission of Small Island States on Climate Change and International Law (COSIS), focusing on the obligations of parties to the United Nations Convention on the Law of the Sea (UNCLOS) to mitigate climate change.

Key Clarifications from the ITLOS Advisory Opinion

The advisory opinion clarified several important aspects regarding climate change and marine pollution:

• Prevention of Marine Pollution: States are obligated to take necessary measures to avert marine pollution resulting from greenhouse gas emissions (GHGs) as per UNCLOS.
• Classification of Carbon Dioxide: The opinion categorizes carbon dioxide produced by human activities as a pollutant detrimental to the marine ecosystem.
• Principle of Prevention: This principle mandates that states should prevent significant harm to shared natural resources, such as oceans, by regulating pollution-causing activities.

Legal Force and Implementation Challenges

While the advisory opinion is not legally binding, it carries substantial political and moral weight. However, challenges remain in its implementation:

• Lack of Specific Methods: The opinion does not provide precise methods for reducing emissions, leaving states to determine how to fulfill their obligations based on their capabilities and resources.

Significance of the ITLOS Ruling

The ruling signifies a critical step towards global cooperation in addressing climate change. It sets a precedent that emphasizes the urgency for robust measures in international climate policies, particularly for vulnerable regions like small island states.
