Litigation Note on Remedies and Reparations

The document distills the International Court of Justice (ICJ) 2025 advisory opinion to assist practitioners in seeking climate-related remedies. It establishes that State responsibility for climate harm is governed by customary international law and can trigger a full range of legal consequences, including cessation, non-repetition, and reparation (restitution, compensation, and satisfaction). The note clarifies that a plurality of contributors does not exempt individual States from responsibility and that scientific evidence allows for the determination of each State's total contribution to global emissions. It further outlines how these findings apply to human rights cases, corporate accountability litigation, and inter-State proceedings.

• The ICJ established that legal consequences for States breaching climate obligations are determined by primary rules and customary rules on State responsibility, specifically noting that climate change treaties do not displace this general international law.
• The material scope of a State's responsibility includes all actions or omissions that adversely affect the climate system through anthropogenic GHG emissions, encompassing both production and consumption activities. This includes failures to regulate private actors, such as neglecting to limit emissions through legislative measures or providing fossil fuel subsidies.
• Climate obligations pertaining to the protection of the climate system are classified as erga omnes (under customary law) or erga omnes partes (under treaties), meaning any State may invoke responsibility for breaches. However, only injured States can claim reparation; non-injured States are limited to claiming cessation and guarantees of non-repetition.
