The UN General Assembly will seek the opinion of the International Court of Justice (ICJ) on countries’ obligations to address climate change, following the adoption by consensus of a resolution on Wednesday.

The resolution was put forward by the cyclone-battered Pacific Island nation of Vanuatu, supported by a “core group” of 17 countries from various regions, and is focused on the adverse impacts of climate change on small island developing States as well as climate justice.

The ICJ, also known as the World Court, is the UN’s principal judicial organ. Although its advisory opinions are not legally binding, they carry legal authority and moral weight.

Speaking ahead of the vote, UN Secretary-General António Guterres noted that the Court’s advisory opinions have tremendous importance.

“If and when given, such an opinion would assist the General Assembly, the UN and Member States, to take the bolder and stronger climate action that our world so desperately needs,” he said.
