Que signifie l'avis consultatif de la Cour internationale de Justice sur le changement climatique pour l'adaptation climatique ?

This briefing by the International Institute for Sustainable Development examines the implications of the International Court of Justice (ICJ) advisory opinion on climate change, specifically regarding climate adaptation. It asserts that adaptation is a binding legal obligation under international law and provides recommendations for states to demonstrate due diligence in preventing and remedying foreseeable climate harms.

• The International Court of Justice (ICJ) has determined that engaging in adaptation planning and implementing adaptation actions is a binding obligation under customary international law and climate treaties, rather than a discretionary domestic policy choice.
• While states maintain discretion over how they plan and implement adaptation based on national circumstances, they must prove they have exercised due diligence. This requires timely adoption of appropriate measures, decisions based on the best available scientific data, and consideration of human rights risks, particularly for vulnerable populations.
• The document recommends that states develop and submit national adaptation strategies, policies, and plans by 2030 to demonstrate their commitment to international law.
• To meet their obligations, states are advised to use a participatory, transparent, and gender-integrated approach that prioritizes vulnerable ecosystems, locations, and people, while adjusting strategies as climate risks evolve.
• Developed states are specifically urged to provide capacity building, technology transfers, and the mobilization of adaptation financing for developing countries.
