The International Court of Justice (ICJ) has delivered a groundbreaking advisory opinion that has the potential to significantly influence global climate action. The Court has determined that States have binding international law obligations to protect the climate system, and failure to do so may constitute an international wrongful act. This opinion stems from a request made by the United Nations General Assembly under Resolution 77/276, seeking clarity on the legal duties of States related to climate change and the repercussions for those causing substantial harm.
Judge Iwasawa Yuji presided over the announcement at the Peace Palace in The Hague, where the Court described climate change as “an existential problem of planetary proportions” and emphasized that safeguarding the climate is crucial for the well-being of present and future generations.
The ICJ articulated that states are obliged to adhere to various legal frameworks, such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Paris Agreement. It affirmed that nations must prepare and uphold Nationally Determined Contributions (NDCs) aimed at limiting global warming to 1.5°C, acting “with due diligence” and utilizing their “best efforts.”
Crucially, the Court linked climate obligations to human rights, emphasizing that the preservation of the climate system is essential to ensuring rights to life, health, and adequate living conditions. This statement highlights the intersection of climate action with broader human rights protections, recognizing the specific vulnerabilities of women, children, and Indigenous peoples.
The ICJ also addressed the duty of states to prevent pollution, specifically greenhouse gas emissions, which it classified as “pollution of the marine environment” under the Law of the Sea. A state causing significant climate harm could be liable for an “internationally wrongful act,” prompting obligations for reparation.
The opinion particularly empowers vulnerable nations, especially small island developing states (SIDS), to seek greater accountability from larger emitters during climate negotiations. The Court acknowledged the unique challenges faced by these nations, affirming their right to hold others accountable for climate-related damages.
The implications of this advisory opinion extend beyond mere legal interpretation. It’s expected to shape climate negotiations, policy decisions, and potential litigation, embedding climate action within enforceable legal commitments rather than relying solely on political goodwill.
Importantly, while the advisory opinion is non-binding, it represents a favorable shift towards recognizing the urgent need for enforceable climate actions on the global stage. By fostering a cooperative approach and highlighting the role of international law in climate justice, the ICJ’s opinion may drive the necessary change to combat the climate crisis effectively.
This moment symbolizes hope for a unified global response to climate change, with the potential to inspire further action and accountability from all nations as the world grapples with this pressing issue.
