On 20 May 2026, after eleven rounds of informal consultations and months of hard-fought negotiation, the General Assembly adopted resolution A/80/L.65 on the Advisory Opinion of the International Court of Justice on the obligations of States in respect of climate change. The vote was 141 in favour, 8 against, and 28 abstentions. As the legal counsel for Vanuatu, Dr Wewerinke-Singh has noted the resolution does more than welcome the Court’s opinion; it “creates a multilateral framework for addressing dimensions of climate harm that the advisory opinion itself left for political actors to take forward.”
What happened in the hours before that vote, however, deserves close attention. The plenary debate shows how the global majority, acting within the most representative organ of the United Nations, the UN General Assembly, interprets international law: States’ climate obligations are rooted in the broader framework of international law. Four amendments were tabled by a few States that had sought to dilute the text; each was put to a vote and decisively rejected.
What follows is a close look at the substantive arguments those States made during their explanations of their vote, whether by sponsoring the amendments, voting against the resolution, or abstaining. They deserve a careful analysis— not because they were legally persuasive, but because they will return to the climate negotiations under the UNFCCC.
The States’ framing argument: the resolution treats a non-binding opinion as binding
The loudest objection, repeated by Saudi Arabia, the United States, the Russian Federation, and India, was that the resolution improperly treats the Advisory Opinion as a binding judgment. This is the most widely recycled argument and also the most confused.
No one disputes that the Opinion is not legally binding as a judgment under Article 65 of the ICJ Statute. The resolution does not claim otherwise. Operative paragraph 1 describes it as “an authoritative contribution to the clarification of existing international law.” The operative paragraphs call on States to comply with obligations that already exist under treaty and customary international law, obligations that the Court has now interpreted and articulated with authoritative force. As Wewerinke-Singh observes, States that voted for the resolution thereby signalled “broad acceptance of the most critical parts of the opinion,” and together with the advisory opinions of International Tribunal on the Law of the Sea (ITLOS) and the Inter-American Court of Human Rights (IACtHR), it confirms that States “can no longer credibly claim that climate obligations are confined to the UNFCCC framework, or that compliance with the Paris Agreement exhausts their legal duties.”
In this context, political disagreement with the rules clarified by the Court, particularly those concerning customary international law, cannot undermine their existence or their binding legal force. The Opinion does not create these obligations; rather, it clarifies them.
The argument that the General Assembly, in following up on a non-binding opinion, somehow overreaches also has no basis in UN practice. General Assembly follow-up to ICJ Advisory Opinions is well established. If accepted here, the argument would mean the Assembly could never act on any advisory opinion, a position that finds no support in the Charter or precedent.
On Operative Paragraph 2: replacing “as identified by the Court” with “taking into account the views of the Court, as appropriate.”
Saudi Arabia’s amendment to operative paragraph 2 was the most explicitly hedged. Replacing “as identified by the Court” with language allowing States to take the Court’s views into account only “as appropriate” would have converted a call to comply with identified legal obligations into an optional suggestion. As Mexico stated clearly at the plenary, obligations identified by the Court as erga omnes do not admit of conditionalities. They are not obligations “as appropriate.”
Saudi Arabia itself affirmed, while tabling the amendment, full respect for the ICJ. To that extent, respect for an institution that is conditional on whether one agrees with its conclusions is not respect for the rule of law and does not change its application. The authority of the ICJ lies precisely in its ability to interpret and articulate what the law requires, even where States would prefer a different result. The amendment failed: 34 in favour, 97 against.
On Operative Paragraph 3: the amendment on climate finance
Algeria introduced an amendment on behalf of a coalition of predominantly Gulf and fossil-fuel-producing states, drawing on the Paris Agreement’s language on means of implementation to argue that the resolution’s silence on finance was a fundamental omission. The argument has real political force. Egypt, Pakistan, and India all made versions of it with evident conviction. But the question in the plenary was not whether climate finance matters — it plainly does — but whether this amendment, at this stage, in this text, was the right vehicle.
It was not, for a straightforward reason. The amendment would have reopened, by way of the UNGA resolution, the very financial provisions of the Paris Agreement that are subject to ongoing and deeply polarised negotiations between the Global North and the Global South countries under the UNFCCC. Alliance of Small Island States (AOSIS), whose members stand to gain more from ambitious climate finance commitments than any other group, opposed the amendment on exactly this basis. As Palau put it, “there is no group that has been a stronger supporter of the Paris Agreement than AOSIS. Our long-held position is that we do not renegotiate the Paris Agreement here in the General Assembly.” Accepting the amendment would have required reopening a carefully balanced resolution text with no guarantee of a better outcome and would have created an opening for further dilution.
It is also worth noting that the resolution is not silent on finance as a matter of legal structure. OP4 references the COP 28 Global Stocktake outcomes on tripling the renewable energy capacity and transitioning away from fossil fuels, commitments that necessarily require adequate financial support. OP10’s request for a Secretary-General report explicitly covers gaps in multilateral efforts. Wewerinke-Singh’s reading of the Secretary-General report provision is apt: it “opens a pathway for multilateral action to safeguard the rights of those who are injured by the conduct that causes climate change, effectively challenging those who are concerned about duplicating efforts under the climate change regime to demonstrate that the UNGA’s action in this area would indeed be duplicative.” The amendment failed: 53 in favour, 91 against.
On Operative Paragraph 4: the amendment on energy transition
The proposed amendment to operative paragraph 4, voted on jointly with the L.66 amendment, rested on the claim that the resolution’s language on fossil fuel transition and the 1.5°C temperature goal selectively rewrote COP 28 outcomes. The Russian Federation was clearest about this at the plenary, arguing that 1.5°C is “an ambitious political goal, but in no way a legally binding threshold.”
This misreads what the Court actually found. The ICJ did not impose 1.5°C as a new treaty obligation. It found that 1.5°C has been recognised as the consensus goal based on the science, the Paris Agreement, and COP decisions, and that States are bound by their own agreed obligations to pursue it. The resolution’s OP4 tracks this precisely. Its language on transitioning away from fossil fuels “in a just, orderly and equitable manner” is drawn from COP 28’s own Global Stocktake, decision 1/CMA.5. It did not originate with the Core Group.
The Russian Federation further argued that the UNFCCC and the Paris Agreement contain no prohibition on fossil fuel extraction and that greenhouse gas emissions do not, by themselves, constitute an unlawful act, a point the Court itself acknowledged. But the resolution does not prohibit fossil fuels. It calls for a transition away from them, consistent with what the states have already agreed to. Pretending the two are the same does not make it so. The amendment failed: 53 in favour, 91 against.
On Operative Paragraph 11: the amendment to delete the follow-up agenda item
Kuwait’s amendment to delete operative paragraph 11, which establishes a follow-up agenda item at the 83rd session, was presented on budgetary and procedural grounds: that, in light of the administrative and budgetary concerns surrounding the UN80 reform initiative, a new standing item after a “contentious process” was inconsistent with General Assembly practice and unwise, as it would not best serve the membership
This reasoning is thin. Decisions to include follow-up items on subsequent session agendas are standard practice after significant legal developments in the UN system and after the delivery of ICJ rulings. The Climate AO involved the highest level of State participation in ICJ proceedings in history. The argument that a single follow-up item is fiscally reckless is a procedural cover for the substantive objection that continued multilateral engagement will provide new platforms for accountability.
The concern that OP11 establishes a parallel mechanism duplicating the UNFCCC is addressed in the text itself. The resolution explicitly states that the Secretary-General’s report must ensure “coordination, coherence and complementarity with existing mechanisms and procedures, including under the UNFCCC and the Paris Agreement,” and that it operates without prejudice to States’ legal positions and obligations. The amendment failed: 33 in favour, 100 against.
On the procedural manoeuvres
The saga over bundling the amendments is worth setting out in sequence, because the voting record tells its own story. Vanuatu moved that all amendments be treated as a single package, prompting Saudi Arabia, Kuwait, Iran, and Pakistan to raise Rule 90 points of order, arguing that each amendment had to be voted on individually. The Assembly voted 92 to 56 in favour of Vanuatu’s bundling motion. At that point, Saudi Arabia withdrew its amendment to OP2 (L.67), and Kuwait withdrew its amendment to delete OP11 (L.68), both citing concern about the precedent of having their proposals subsumed into a package vote. The two remaining amendments – L.66 on climate finance (OP3) and L.69/Rev.1 on energy transition (OP4), were then put to a joint vote and failed: 53 in favour, 91 against. Saudi Arabia and Kuwait then reintroduced their withdrawn amendments under Rule 80, and these were voted on individually. The amendment to delete OP11 failed: 33 in favour, 100 against, 23 abstentions. The amendment to OP2 failed: 34 in favour, 97 against, 26 abstentions. The resolution itself was then adopted: 141 in favour, 8 against, 28 abstentions. The procedural strategy pursued by the group of countries proposing last-minute amendments, withdrawing two of the four of these amendment-proposals to avoid their inclusion in a package vote and later reintroducing them under Rule 80 for individual consideration, backfired at every vote and, if anything, sharpened the signal that the General Assembly had weighed these arguments, rejected them, and instead demonstrated notable support for the resolution as proposed.
The arguments advanced against it were not frivolous; the concerns about finance, about UNFCCC primacy, and about process carry genuine political weight. But they were not arguments for improving the resolution. As Wewerinke-Singh has noted, the late-introduced amendments, “read alongside the advisory opinion,” would have substituted the Court’s integrated identification of legal obligations with “selectively extracted, programmatic language from the Paris Agreement’s objectives clause.” Their effect would have been to make it harder, not easier, for climate-vulnerable states to anchor demands for accountability in the Court’s own reasoning.
What comes next
141 States voted for this resolution.
The resolution now establishes, with the imprimatur of the General Assembly, that obligations governing climate change exist across the full breadth of international law, that breaches carry legal consequences, and that follow-up is not optional. The Secretary-General’s report, due at the 82nd session, and the agenda item at the 83rd session, are the next steps.
As Belize put it on behalf of AOSIS: “Future generations will ask whether we rose to meet this challenge with the full force of international law. Today, the General Assembly answered: yes.” The task now is to make that answer mean something.
The first real test of that commitment is already underway. The UN Special Rapporteur on human rights and climate change has called on the 141 States that voted in favour to now “live up to their commitment to translate the Court’s findings into enhanced multilateral cooperation,” and has urged States that abstained or voted against to engage constructively, without attempting to prevent negotiations based on the Advisory Opinion altogether. In concrete terms, this means three things. In the climate finance negotiations, States cannot invoke cooperative obligations while resisting the Court’s finding that those obligations are stringent and legally binding in character; the Advisory Opinion does not reopen the Paris Agreement’s finance architecture, but it does raise the legal floor beneath it. In the Mitigation Work Programme, the Court’s due diligence standard — explicitly described in the resolution as stringent — should inform the ambition and timelines States are prepared to accept. And across the negotiations more broadly, the Advisory Opinion needs to be socialised as the authoritative legal framework it is, so that when parties arrive at COP 31, the space to anchor outcomes in the Court’s reasoning is already in place.
In the halls of the SB 64s, the voting decisions in New York are drawing negative attention on the incoming host of COP 31, Türkiye, and the host of COP 32, Ethiopia, as both countries have chosen to abstain from the vote. The signal these States should be sending, as stewards of the world’s climate negotiations, should be clear, yet it remains questionable. The Secretary-General said it plainly on adoption day: the path to climate justice runs through a rapid, just, and equitable transition away from fossil fuels.
