An advisory opinion from the International Court of Justice last year left no doubt that states have a legal obligation to prevent significant harm to the climate system, and that a failure to do so carries legal consequences. Now, a new United Nations resolution seeks to put this ruling into practice.
By Ralph Regenvanu
PORT VILA—Last year, the International Court of Justice (ICJ) delivered a legal opinion on climate change with a clarity of purpose not seen since the 2015 Paris agreement. It left no doubt that states have a legal obligation to prevent significant harm to the climate system, and that failure to do so carries legal consequences.
My own country, Vanuatu, brought this question to the world and to the ICJ. But we were not alone. We built a coalition of countries spanning every region and gained sustained support from youth movements. Ultimately, 132 countries co-sponsored a motion for a United Nations resolution asking the ICJ to rule on the matter, which then passed by consensus. It was a historic moment, and one that did not happen by accident.
Now we are back at the UN General Assembly, presenting a resolution to give the ICJ’s advisory opinion practical effect and calling on the world to support it. It is normal practice for ICJ advisory opinions to go back to the UN General Assembly, where resolutions give member states an opportunity to amplify such rulings’ political and normative authority. This new resolution not only calls on the UN to endorse the opinion but also urges all member states to uphold the obligations that the Court identified. It sets the stage for follow-up action within the UN system, such as a formal request to the secretary-general to find ways to advance compliance.
We believe this new resolution is the best way to ensure that legal obligations to deal with climate change do not just sit on a shelf. They must be reflected in the real world, even if certain states would rather pretend that the ruling did not happen.
We are under no illusions that the ICJ’s ruling will be difficult for some countries to implement. But we cannot ignore the costs of inaction. This is a critical moment, not just for the climate but also for the future of international cooperation. The entire postwar, post-colonial multilateral order is under significant pressure. Large states are withdrawing from international agreements and withholding funding from multilateral organizations. Bilateral deals are replacing collective frameworks. Many fear that the global architecture of rules, norms, courts, and international accountability is crumbling before our eyes.
In this context, reaffirming the role of institutions like the ICJ would be a shot in the arm for multilateralism. What Vanuatu, a country of only around 340,000 people, has accomplished shows that the system can still function. We took a legal question to the appropriate institution, and that institution did its job. The process was slow, and we faced plenty of resistance along the way. But justice prevailed. All states had a chance to argue before the Court, whether they were for or against the motion, and the outcome was clear.
International response to climate change
The ruling gave vulnerable people around the world hope and lent new momentum to multilateral climate action, especially the UN Framework Convention on Climate Change—the process that has organized the international response to climate change for more than 30 years. Everyone participating in the annual UN Climate Change Conferences (COPs) now knows where the world court stands. The obligation to cooperate on meaningful solutions is not merely political and moral, but legal.
Following weeks of negotiations, our new resolution has been shaped by input from almost every UN member state and facilitated by a core group of countries from every region of the world. That breadth of engagement is no accident. It shows that the appetite for a truly global response to climate change remains strong, even at this fraught geopolitical moment.
There is no defensible reason for states to vote against the resolution. If we fail here, we will be signaling to current and future generations that we have moved from a system built on cooperation to one governed by power alone. We will be conceding that pressure from vested interests can derail the progress we have made toward guaranteeing our collective survival.
It is no secret that powerful vested interests want to delay the transition away from fossil fuels. Despite the rapidly falling costs of renewables, they have no problem leveraging their money and influence to frustrate efforts to mitigate climate change. Small island states like Vanuatu are particularly vulnerable to these bad-faith actors.
Still, the world is now witnessing the consequences of relying on a fossil-fuel economy. While Vanuatu has long been vulnerable to growing climate-related risks like cyclones and drought, we are currently experiencing a different kind of storm. Those fueling up at gas stations in Port Vila are seeing the same high prices as hundreds of millions of others around the world. We are all learning the hard way what a failure to phase out fossil fuels looks like.
The conflict in the Middle East reminds us that fossil fuels do not just heat the planet; they also inflame conflicts. The sooner all of us move away from such volatility, the better.
Rising seas
We all have a duty to keep fighting for international cooperation, because the alternative—a world that stops trying to solve its hardest problems collectively—would be worse than the current one. Vanuatu and its many like-minded partners will continue to push forward, not only on behalf of our own communities but on behalf of yours, too. Billions of people are already facing, or will soon face, rising seas, intensifying storms, deadly wildfires, and the relentless erosion of everything we have built.
The law has spoken. The question confronting every state is simple: We know the rule of law applies to climate change, but do you intend to act on it?

Executive Summary

The International Court of Justice (ICJ) issued an advisory opinion last year stating that states have a legal obligation to prevent significant harm to the climate system, and failure to comply carries legal consequences. This ruling was prompted by a motion co-sponsored by 132 countries. Following this, a new United Nations resolution was presented to give the ICJ’s advisory opinion practical effect and calls on member states to uphold the identified obligations. The author argues that this process reinforces the role of international institutions like the ICJ in addressing climate change and emphasizes that the legal obligation is not merely political or moral, but legally binding. The text posits that this action is necessary to prevent inaction, noting growing pressure on the existing multilateral order and the need to counter vested interests delaying climate transition.

Full Take

The narrative frames the climate crisis as a legal failure requiring immediate institutional enforcement. The core pattern involves elevating a legal finding into a moral imperative, leveraging the authority of the ICJ and the UN to pressure states that are perceived as acting against collective survival. This tactic utilizes fear appeals—specifically concerning the crumbling of the international system and the costs of inaction—to build consensus and demand action. The argument relies heavily on establishing a binary choice: either states act based on the rule of law or they concede that progress is being derailed by powerful, vested interests. This framing shifts the focus from complex geopolitical and economic drivers of climate change to the failure of adherence to existing legal structures. The invocation of the "postwar, post-colonial multilateral order" functions to create a sense of historical grievance and urgency, suggesting that current systemic pressures are not merely economic but existential threats to global cooperation. The implication is that the institutional framework itself is under threat, requiring a defensive, legal-based assertion of authority to resist fragmentation. The focus on small states like Vanuatu demonstrates a pattern of using marginalized voices to assert systemic accountability.
