UN General Assembly adopts World Court climate accountability ruling

The United Nations (UN) General Assembly overwhelmingly adopted a landmark climate accountability resolution backing the International Court of Justice’s (ICJ) ruling that countries have a legal obligation to reduce carbon pollution and prevent worsening climate change. Spearheaded by Vanuatu, the resolution passed 141-8.

The ICJ, also known as the World Court, ruled that countries are bound by international law to tackle rising greenhouse gas emissions, and could face legal consequences if they don’t, based on various sources of international law, including environmental and human rights treaties.

Eight nations—including the United States, Russia, and Saudi Arabia—voted against the resolution, which calls on UN member states to step up actions to limit global emissions, eliminate inefficient fossil fuel subsidies, and achieve net-zero targets, citing concerns over legal enforcement and fossil fuel transitions.

“Today’s vote marks an important step in advancing climate justice,” said Camile Cortez, a senior campaigner on Climate Justice at Amnesty International. “By adopting this resolution, states have recognized that they have legal duties to address the profound human rights crisis posed by climate change as set forth in the 2025 International Court of Justice’s (ICJ) Advisory Opinion. This resolution brings renewed momentum towards ensuring accountability for climate-driven human rights harms and protecting present and future generations.”

The ICJ is the principal judicial organ of the United Nations. Located at the Peace Palace in The Hague, Netherlands, it settles legal disputes between countries and provides advisory opinions on international legal questions. Unlike the International Criminal Court (ICC), which prosecutes individuals, the ICJ only has jurisdiction over disputes between nations.

“At a time when fragmentation between nations feels more visible than ever, the UN resolution endorsing the ICJ climate ruling offers a renewed path for international cooperation,” said Cortez. “Political and authoritarian choices by some world leaders, like rolling back climate protections or revoking phase out regulations, have weakened global progress just when we need stronger climate action. Fossil fuel infrastructure alone poses risks for the health and livelihoods of at least 2 billion people globally, roughly a quarter of the world’s population.

“This new UN resolution paves the way for governments to show they stand for climate justice and has the potential to shape global climate accountability for years to come,” said Cortez.

The UN climate accountability resolution seeks to turn the ICJ Advisory Opinion on states’ obligations concerning the “urgent and existential threat” posed by climate change, into a roadmap for concrete action and accountability.

Vanuatu, which has repeatedly warned that it could disappear under rising sea levels, spearheaded the efforts to secure the resolution. The Pacific island nation and archipelago had previously also led the diplomatic drive for the ICJ’s 2025 Advisory Opinion through active campaigning initiated by a group of young law students.  

In a rare unanimous opinion, the ICJ made it clear that protecting the global climate system is a legal obligation – not a political choice.

Failure to do so threatens human rights and the well-being of present and future generations. The ICJ also stated that countries must act together to remediate existing harm and prevent more climate havoc.

In a bid to ‘operationalize’ this ICJ Advisory Opinion, a core group of states contributed to the “zero draft” first version of the resolution adopted, with cross-regional representation from Vanuatu, Barbados, Burkina Faso, Colombia, Jamaica, Kenya, the Marshall Islands, the Federated States of Micronesia, the Kingdom of the Netherlands, Palau, the Philippines, Singapore, and Sierra Leone.

Although not legally binding, the landmark 2025 opinion from the world’s highest court is widely seen as an authoritative statement that clarified states’ responsibilities regarding climate change.

It will greatly boost efforts to hold world leaders accountable, support the fair and balanced phaseout of fossil fuels, strengthen climate laws and policies, and promote climate justice for billions of people around the world.

Vanuatu, a nation that has often warned it could vanish due to rising sea levels, led the push to secure the resolution.

The Pacific island nation and archipelago also led the diplomatic drive for the ICJ’s 2025 advisory opinion through active campaigning initiated by a group of young law students.

The archipelago, which is of volcanic origin, is 1,090 miles east of northern Australia, 335 miles northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji.

The historic Advisory Opinion marked the first time the ICJ had examined the international legal framework as it applies to climate change. It is a milestone that was made possible by years of campaigning that brought together governments, youth movements, civil society organizations and frontline communities demanding climate action.

To reach its opinion, 15 judges from around the world sought to answer two central questions: what obligations do states have under international law to protect the climate and environment from human-caused greenhouse gas emissions, and what are the legal consequences for governments where their acts, or lack of action, have significantly harmed the climate and environment?

In a rare unanimous opinion, the ICJ made it clear that protecting the global climate system is a legal obligation – not a political choice. Not to do so threatens human rights and the well-being of present and future generations. The ICJ also stated that countries must act together to remediate existing harm and prevent more climate havoc.
