Landmark Advisory Opinion on Climate Change Expected in 2025
The ICJ is expected to issue a landmark advisory opinion in 2025 outlining states' responsibilities in combating climate change, a move that could significantly influence future national and international legal actions.

The International Court of Justice (ICJ) is set to deliver a pivotal advisory opinion in 2025 that will clarify state responsibilities in addressing climate change. Initiated by Vanuatu and supported by over 130 countries, the case focuses on determining the legal obligations of states to protect the climate system from anthropogenic greenhouse gas emissions. Although the opinion is not legally binding, it is expected to carry significant political and legal weight on both national and international stages.
Recent hearings held in December 2024 have highlighted the global urgency of this issue, with nations like China asserting that UN treaties already encompass these climate obligations. The advisory opinion, anticipated by late 2025, comes amid a growing number of climate-related cases, marking a critical moment in international efforts to address the impacts of climate change. Detailed discussions during the hearings suggest that the outcome could shape future legal and policy actions against significant greenhouse gas emitters.
