The United Nations General Assembly recently adopted a landmark resolution, by a vote of 141-8 with 28 abstentions, backing an International Court of Justice (ICJ) advisory opinion concerning countries' legal obligations to address climate change. This significant vote underscored the responsibility of governments to protect their citizens from the escalating climate crisis, as highlighted by UN Secretary-General António Guterres. He welcomed the resolution as a powerful affirmation of international law, climate justice, science, and the duties of states.

The resolution, spearheaded by the Pacific island nation of Vanuatu, affirms a July 2025 ICJ advisory opinion stating that nations are obligated to reduce fossil fuel use and combat global warming. While not legally binding, this advisory opinion is already making an impact, being cited in climate litigation worldwide and referenced by judges in their climate-related rulings. However, its use as a diplomatic tool has proven more challenging, notably failing to gain traction at last year’s UNFCCC climate talks in Belem, where Saudi Arabia deemed its inclusion a “red, red line.”

A small group of eight countries opposed the resolution: the United States, Saudi Arabia, Russia, Israel, Iran, Yemen, Liberia, and Belarus. The US, recognized as the world’s largest historical emitter, was among the prominent dissenters. Its deputy ambassador to the UN, Tammy Bruce, stated that the resolution contained “inappropriate political demands relating to fossil fuels” and that Washington saw no basis for requiring the secretary-general to report on the legal issues. The Trump administration, known for withdrawing the US from the Paris climate agreement and other environmental accords while boosting fossil fuel production, had reportedly urged other nations to pressure Vanuatu to withdraw the resolution.

Among the countries that abstained from the vote were Cop31 climate summit host Turkey, India, and major oil producers Qatar and Nigeria. In contrast, 141 nations, including Australia, Germany, France, and the UK, voted in favor, signaling broad international support for the ICJ's stance on climate obligations.

Vanuatu’s ambassador to the UN, Odo Tevi, passionately articulated the resolution’s importance, emphasizing the tangible harm already affecting island and coastal communities through droughts and failed harvests. He stressed that those bearing the heaviest burden often contributed least to the problem. Vanuatu’s Minister of Climate Change, Ralph Regenvanu, further asserted that in the current geopolitical climate, a sustained commitment to the rule of law is crucial, and climate change is no exception. Upholding the court's clarification of existing obligations is essential for the credibility of the international system and for effective collective action.

For decades, Pacific nations have witnessed the gradual disappearance of their homelands due to climate change. In Tuvalu, where the average elevation is merely two meters above sea level, over a third of the population has sought climate migration visas to Australia, with projections indicating much of the country will be underwater by 2100. Nauru’s government has resorted to selling passports to wealthy foreigners to generate revenue for potential relocation efforts. The Paris climate agreement, established in 2015, aimed to limit global warming to 1.5 degrees Celsius above preindustrial levels; however, scientists now suggest even best-case scenarios may surpass this critical target. Vishal Prasad, director of Pacific Islands Students Fighting Climate Change, which spearheaded the campaign for an ICJ opinion, viewed the vote as a commitment to making these climate goals a reality.
