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

The document argues that climate adaptation is a binding legal obligation under international law and treaties, rather than a discretionary domestic policy choice. It outlines how states must demonstrate due diligence by using the best available scientific data, prioritizing vulnerable populations, and implementing national adaptation plans by 2030. Additionally, it recommends that developed nations provide financing, technology transfers, and capacity building to developing countries to meet these obligations.

• The International Court of Justice (ICJ) has determined that planning and implementing climate adaptation is a binding legal obligation under customary international law and climate treaties, not a discretionary policy choice.
• While states maintain some discretion based on national circumstances, they must prove they have exercised due diligence to prevent and address foreseeable climate harm. This requires timely adaptation measures, decisions based on the best available scientific data, and consideration of human rights risks, especially for vulnerable groups.
• To demonstrate compliance with international law, states are advised to develop and submit national adaptation strategies, policies, and plans with a goal of progressing in their implementation by 2030.
• Developed states have a specific responsibility to mobilize and provide capacity building, technology transfers, and adaptation financing for developing countries.
