The International Court of Justice held significant hearings from December 2 to 13 concerning the responsibilities of States under international law in combating climate change. Small island nations, particularly Vanuatu, emphasized the dire consequences of climate change and sought justice for their plight. Countries including Brazil and China highlighted the need for differentiated responsibilities, while positions diverged on the binding nature of climate treaties. The awaited advisory opinion is expected to influence future international climate law, critical for vulnerable communities.

The International Court of Justice (ICJ) conducted landmark hearings from December 2 to December 13, addressing the obligations of States under international law concerning climate change. This process, initiated through a UN General Assembly resolution, involved 96 nations and 11 regional organizations articulating their perspectives on the responsibilities of States in relation to climate change. Although the anticipated advisory opinion will be non-binding, it is poised to significantly influence the evolution of international climate law.

The hearings commenced with passionate appeals from representatives of small island nations, particularly Vanuatu and the Melanesian Spearhead Group, which face dire consequences from climate change. Ralph Regenvanu, Vanuatu’s special envoy for climate change, emphasized the historical importance of the proceedings, stating that their outcomes would affect future generations and the fate of vulnerable nations. Moreover, Vanuatu’s Attorney General Arnold Kiel Loughman asserted that high-emitting States’ failure to discharge their international obligations is an affront to humanity and leads the world closer to disaster.

The Alliance of Small Island States (AOSIS), representing small island developing States (SIDS), urged the World Court to endorse international legal principles that address challenges such as sea-level rise. Their request included recognizing maritime boundaries and statehood irrespective of territorial inundation, thereby seeking justice for those most threatened by climate change.

Brazil voiced its commitment to substantial emissions reductions while highlighting the significant difficulties faced by developing nations like itself. Luiz Alberto Figueiredo Machado, Brazil’s special envoy on climate change, articulated the principle of “common but differentiated responsibilities,” stressing that developed nations should be held accountable for greater climate action. Meanwhile, China emphasized the need for the ICJ to work within existing frameworks, advocating for historical responsibility from developed countries while allowing developing nations extended timelines to achieve climate objectives.

The United States acknowledged the severity of the climate issue but contended that international treaties, such as the Paris Agreement, do not impose legal obligations. U.S. representative Margaret Taylor further refuted the concept of “common but differentiated responsibilities” as a cornerstone of international law. Conversely, the European Union (EU) advocated for cooperative approaches, underscoring the significance of current treaties without pushing for enforcement mechanisms.

As the ICJ continues its deliberations, the legal interpretations regarding State responsibilities for climate change await the court’s advisory opinion. For small island nations and at-risk communities, the implications of these proceedings hold grave existential significance.

The hearings at the International Court of Justice mark a crucial moment in recognizing and addressing the obligations of States to combat climate change, particularly highlighting the urgent situation faced by vulnerable nations like small island states. This is part of a greater global effort, initiated by a UN resolution, to assess and define the legal responsibilities that various nations have towards climate change mitigation and adaptation, amid ongoing debates on accountability and differentiated responsibilities in global climate action.

The ICJ hearings represent a pivotal development in international climate law, underscoring the responsibilities of States, particularly for major emitters. Voices from small island nations advocate for recognition and protection against climate impacts, while varying perspectives from larger countries such as the U.S., EU, Brazil, and China reveal tensions over responsibilities and legal frameworks. The forthcoming advisory opinion may provide critical guidance for future climate actions and obligations of States globally.
