Recent advisory opinions from the International Court of Justice (ICJ) have emphasized that sovereign states are legally responsible for mitigating climate change and have the obligation to curb fossil fuel emissions. This monumental ruling has sparked discussions about the accountability of nations and corporations regarding greenhouse gas emissions and associated climate damage. Legal experts and leaders from Pacific communities, including Vanuatu, express optimism over the decision, interpreting it as a catalyst for potential massive lawsuits between nations and a shift towards climate justice. However, questions remain about the gender aspects of climate justice and the implications for military emissions. While the ruling is celebrated as a watershed moment, it also poses new challenges regarding corporate liability and compliance risks in the face of climate change litigation. As global calls for climate action grow louder, the ruling underscores the urgent need for concerted efforts in protecting the climate, while placing financial markets and corporations on notice about their roles in the climate crisis.
