Que signifie l'avis consultatif de la Cour internationale de Justice sur le changement climatique pour les accords environnementaux multilatéraux ?

This policy brief examines the implications of the International Court of Justice (ICJ) advisory opinion on climate change for multilateral environmental agreements (MEAs), emphasizing that states must now implement climate provisions in an integrated and systemic manner to ensure compliance with international law.

• The ICJ advisory opinion transforms the coordination of climate provisions across different multilateral environmental agreements (MEAs) from a discretionary activity into a requirement for assessing due diligence and compliance with international law.
• States are required to integrate climate-related impacts, factors, and obligations when fulfilling their duties under MEAs, such as the Convention on Biological Diversity and the United Nations Convention to Combat Desertification. Conversely, a state's compliance with the international climate regime is evaluated based on its efforts to protect human rights, oceans, land, and biodiversity.
• The document recommends that states align national policies and actions with legal obligations from the international climate regime, human rights law, and other MEAs, while continuously assessing national capacities to ensure differentiated responsibilities reflect the highest possible ambition.
• The ICJ advisory opinion establishes specific legal obligations across other domains: climate adaptation is no longer optional, there is a legal obligation to phase out environmentally harmful subsidies, downstream emissions from fossil fuel combustion must be included in environmental impact assessments, and investment protection cannot override state climate obligations.
