Implications of ICJ Advisory Opinion on the Climate Obligations of African States

On July 23, 2025, at the request of the United Nations General Assembly, the International Court of Justice (ICJ) delivered a unanimous opinion on the

obligations of states in the context of climate change. In this historic opinion, the court confirmed

that there are international law obligations of states to advance climate action, and that there can

be legal consequences arising from acts and omissions that cause significant harm to the climate

system and other parts of the environment.

Although the advisory opinion is not legally enforceable and binding, it carries significant legal

implications for states and ought to influence how African countries make decisions relating to

climate policy in the years ahead. Significantly, the decision provides authoritative legal guidance

from the world’s highest international court, cementing the importance of state climate obligations.
