On July 23, 2025, the International Court of Justice (ICJ) is poised to deliver a significant advisory opinion regarding states’ legal responsibilities in the face of climate change—an event hailed as a historic milestone for climate justice. This moment represents the culmination of a six-year campaign driven by Pacific youth, the Republic of Vanuatu, and various Pacific Island nations advocating for accountability and legal clarity in the battle against climate inaction.
Ralph Regenvanu, Vanuatu’s Minister for Climate Change, has underscored the transformative potential of this ruling. He noted, “This is a turning point for climate justice,” expressing hopes that the court will affirm the rule of law in addressing the climate crisis. The opinion is expected to clarify states’ obligations under international law, including human rights and environmental protections, specifically in their duty to prevent climate harm and; safeguard the rights of vulnerable populations.
The initiative for the advisory opinion was initially proposed by a coalition of law students from the Pacific Islands, emphasizing urgent legal clarity on climate action. Vishal Prasad, Director of the Pacific Islands Students Fighting Climate Change (PISFCC), reflected on the campaign’s significance, stating, “This opinion is a tool for justice—an opportunity to transition from systems of oppression to systems of change.” He highlighted the role of youth advocacy as a driving force in pushing for bold systemic reforms in climate justice, reinforcing that this ruling could provide crucial legal backing for ongoing advocacy efforts.
The potential consequences of the ICJ’s opinion extend beyond mere legal documentation. According to Coral Pasisi, Director of Climate Change and Sustainability at the Pacific Community, the court’s decision could bear significant weight in shaping global climate negotiations, thereby providing small island nations with a platform to demand reparations and climate finance from major polluters. As these nations grapple with rising sea levels, intensified storms, and the looming threat of catastrophic warming, the advisory opinion could serve as a beacon of hope, amplifying the voices of those most impacted by climate change.
This ruling, while advisory and non-binding, could significantly influence climate litigation and treaty negotiations, addressing long-standing calls for accountability from developed nations. The expectation is that the ICJ will underscore the urgent need for enforceability within international climate frameworks, empowering vulnerable nations by holding larger emitters accountable for their actions that contribute to climate harm.
As anticipation builds for the ICJ’s decision, the forthcoming opinion is viewed as a pivotal moment not only for the Pacific Islands but also for the global fight against climate change, offering a renewed sense of hope that legal frameworks may catch up with the scientific realities and needs of those at the front lines of the climate crisis.
