The International Court of Justice (ICJ) ruled that nations have a legal obligation to mitigate climate change, potentially facing liability for climate-related damages. This advisory opinion, a victory for vulnerable nations like Vanuatu, could bolster ongoing climate lawsuits globally. While not legally binding, the decision carries significant weight, potentially influencing future international negotiations and national court cases. The ruling emphasizes the need for emissions reduction and acknowledges states' responsibility for climate-caused harm. The US, which considers the decision non-binding, previously withdrew from the Paris Agreement.
