The European Union has formally welcomed the United Nations General Assembly’s adoption of a resolution endorsing the International Court of Justice’s (ICJ) Advisory Opinion on states’ obligations in relation to climate change, calling the move a “major step” for international law and global climate action. In a statement delivered at the UN General Assembly on Wednesday, the EU praised Vanuatu for steering the process over the past three and a half years and said the resolution reflects a renewed global commitment to tackling climate change through legal clarification and cooperation.
The EU said the ICJ’s advisory opinion provided “important clarifications” about states’ duties in relation to anthropogenic greenhouse gas emissions, including the obligation of parties to the Paris Agreement to “prepare, communicate and maintain successive and progressive Nationally Determined Contributions” (NDCs). The bloc reaffirmed its firm support for the Court and for the development and strict observance of international law as a tool to hold states to account on climate obligations.
Linking legal developments to the physical reality of climate change, the EU cited the European State of the Climate 2025 report, noting that Europe experienced record marine heatwaves, devastating wildfires and severe drought last year. The EU highlighted the report’s finding that Europe has warmed twice as fast as the global average over the past 30 years, underlining that climate change is already an immediate, cross-regional crisis rather than a distant threat.
Against that backdrop, the EU reiterated its mitigation and adaptation commitments. It restated greenhouse gas reduction targets of at least 55 percent by 2030 and 90 percent by 2040 compared with 1990 levels, and backed ambitions to triple renewable energy capacity and double energy efficiency improvements by 2030. The statement also reaffirmed the EU’s position as one of the world’s largest contributors to climate finance, pointing to ongoing support for adaptation funding and the Fund for Responding to Loss and Damage.
The EU explicitly acknowledged the particular vulnerability of Pacific island nations and other low-lying coastal states to sea-level rise, noting the ICJ’s observations that the disappearance of territory would not automatically mean loss of statehood. That recognition follows sustained advocacy from Pacific countries, including Vanuatu and Fiji, which have urged stronger global action and legal tools to protect their territories and populations.
At the same time, the EU warned against creating follow-up mechanisms or legal instruments that extend beyond the scope of the ICJ’s advisory opinion. “The envisaged report should not go beyond the scope of the Advisory Opinion. It should neither seek to establish new mechanisms nor engage in any determination of State responsibility,” the bloc said, signaling caution about pushing for novel legal avenues outside established frameworks.
The statement concluded that the EU will continue to address climate change within existing international agreements, including the UN Framework Convention on Climate Change and the Paris Agreement, while working with other states to implement the legal clarifications set out by the Court. For Pacific island nations and other vulnerable states, the EU’s message combines recognition of legal and climatic urgency with a pledge of climate finance and a cautious approach to how international law is developed in response.
