World's top court paves way for climate reparations

World's top court paves way for climate reparations

The ICJ will deliver a historic climate ruling

The world's highest court Wednesday declared that states are obliged under international law to tackle climate change and warned that failing to do so could open the door to reparations.

In a historic statement, the International Court of Justice said climate change was an "urgent and existential threat" and countries had a legal duty to prevent harm from their planet-warming pollution.

Countries breaching their climate obligations were committing a "wrongful act", the court said in its advisory opinion, which is not legally binding but carries political and legal weight.

"The legal consequences resulting from the commission of an internationally wrongful act may include... full reparations to injured states in the form of restitution, compensation and satisfaction," said ICJ President Yuji Iwasawa on behalf of the 15-judge panel.

This would be on a case-by-case basis where a "sufficient direct and certain causal nexus" had been shown "between the wrongful act and the injury", the court added.

Campaigners and countries on the climate frontlines hailed a milestone moment in the fight for accountability from big polluters most responsible for global warming.

"This is a victory for our planet, for climate justice and for the power of young people to make a difference," said UN Secretary-General Antonio Guterres.

Ralph Regenvanu, the climate change minister for Vanuatu, the Pacific island nation that spearheaded the case at The Hague, was jubilant.

Speaking to AFP outside the court, Regenvanu said it was "a very strong opinion at the end" and better than hoped. 

"We can use these arguments when we talk with our partners, some of the high-emitting states. We can say you have a legal obligation to help us," he said. 

"This helps us in our arguments. It's going to give us a lot more leverage... in all negotiations."

- Catalyst for change -

This was the biggest case in ICJ history, and seen as the most consequential in a recent string of landmark climate moves.

The United Nations had tasked the 15 judges at the ICJ, a UN court in The Hague that adjudicates disputes between nations, to answer two fundamental questions.

First: what must states do under international law to protect the environment from greenhouse gas emissions for the future?

Second: what are the consequences for states whose emissions have caused environmental harm, especially to vulnerable low-lying island states?

In a detailed summary of the opinion, Iwasawa said the climate "must be protected for present and future generations".

The adverse effect of a warming planet "may significantly impair the enjoyment of certain human rights, including the right to life", he added.

Legal and climate experts said the opinion, while not legally binding, could have far-reaching consequences for national courts, legislation and public debate.

"The court's clear and detailed articulation of state obligations will be a catalyst for accelerated climate action and unprecedented accountability," David Boyd, a former UN Special Rapporteur on Human Rights and the Environment, told AFP.

Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research, said the ruling bound all nations by international law to prevent harm from emissions of planet-warming greenhouse gases.   

The court was "pointing the direction for the entire world and making clear that every nation is legally obliged to solve the climate crisis", he told AFP.

- Classroom to court -

Courts have become a key battleground for climate action as frustration has grown over sluggish progress toward curbing planet-warming pollution from fossil fuels.

The Paris Agreement, struck through the UN Framework Convention on Climate Change (UNFCCC), has rallied a global response to the crisis, but not at the speed necessary to protect the world from dangerous overheating.

The journey to The Hague began six years ago with students from the climate-imperilled Pacific region fed up with the lack of accountability for the damage afflicting their homelands.

"Young Pacific Islanders initiated this call for humanity to the world. And the world must respond," said UN chief Guterres, praising Vanuatu's leadership.

The fight pitted major wealthy economies against the smaller, less developed states which are most at the mercy of a warming planet.

More than 100 nations and groups made submissions, many from the Pacific who gave impassioned appeals in colourful traditional dress.

"It's such a perfect ending to a campaign that started in a classroom," said Vishal Prasad, director of the student-led campaign that kicked off the case.

"We have now a very, very strong tool to hold power accountable, and we must do that now. The ICJ has given everything possible," he told AFP.

French Ecological Transition Minister Agnes Pannier-Runacher hailed the advisory opinion as a "victory for the most vulnerable states, a victory for France and a victory for the climate".

John Kerry, the former US special envoy for climate change, said "it should not take the stamp of international law to motivate countries to do what is already profoundly in their economic interests".

"We shouldn't need another reason to act and accelerate action," he told AFP.
