Que signifie l'avis consultatif de la Cour internationale de Justice sur le changement climatique pour le droit international des investissements ?

The document argues that the International Court of Justice (ICJ) has established climate action as a binding legal obligation, meaning investment protections cannot override a state's climate duties. It suggests that this ruling challenges the legal basis of Investor-State Dispute Settlement (ISDS) claims against climate regulations, such as coal phase-outs or drilling bans. The brief recommends that states implement specific climate exclusion clauses in treaties, restrict prospective damages based on speculative future revenues, terminate obsolete investment treaties, and pursue a fundamental reform of the international investment regime.

• The International Court of Justice (ICJ) has determined that climate action is a binding legal obligation under international law rather than a discretionary policy choice, placing climate obligations and investment law on equal legal footing.
• The ICJ's advisory opinion challenges the legal foundations of Investor-State Dispute Settlement (ISDS) cases where investors claim that climate measures, such as coal phase-outs or drilling bans, violate investment protections.
• Commonly invoked ISDS standards—including fair and equitable treatment, protection against expropriation, and fair market value for compensation—can now be contested because investment treaties must be interpreted in light of states' binding climate obligations.
• To align investment governance with climate action, states are advised to adopt plurilateral climate exclusion clauses, limit prospective compensation based on speculative future revenues, terminate obsolete treaties (including their survival clauses), and reform the international investment regime.
