In 2026, IGSD updated its compendium of key climate jurisprudence to reflect the monumental developments represented by the 2025 climate Advisory Opinions from the Inter-American Court of Human Rights and the International Court of Justice. Summaries and analyses of these opinions can now be found in Annex 2 of the document. The compendium now covers all 3 climate advisory opinions from major international courts and tribunals; the International Tribunal for the Law of the Sea (ITLOS), the Inter-American Court of Human Rights, and the ICJ.
IGSD’s original jurisprudence compendium of key climate cases, published in June 2025, analyzed 28 climate cases from 21 jurisdictions worldwide.
These cases were selected to highlight the following important themes in global climate change jurisprudence.
- Supervision and accountability of state and non-state actors in addressing climate change
- Use and importance of climate science
- Human rights and climate change
- States’ obligations under international treaties to address climate change
- Judicial development and evolution of legal principles to address climate change
- Access to justice and legal standing to bring climate cases
