WASHINGTON, CMC – Inadequate consideration has been given to the far-reaching actions taken by a number of small island states, led by Antigua and Barbuda and Tuvalu, to problem the destruction of their international locations by main world polluters.
In December 2022, these states boldly requested the first-ever advisory opinion on local weather change from the Worldwide Tribunal for the Regulation of the Sea (ITLOS). This request sought readability on states’ obligations beneath the United Nations Conference on the Regulation of the Sea (UNCLOS) to guard oceans from the antagonistic results of local weather change attributable to greenhouse gasoline (GHG) emissions.
In Might 2024, ITLOS delivered a historic, unanimous opinion confirming that GHG emissions represent marine air pollution, obligating states to take affirmative steps to guard the marine atmosphere primarily based on scientific proof to forestall catastrophic hurt. This opinion has allowed all states—not simply small island creating states (SIDS)—to pursue local weather justice. It is usually prone to affect how worldwide and nationwide courts deal with local weather change as different creating states push again in opposition to the threats to their international locations attributable to emissions from industrialized nations.
Frustration with the insufficient outcomes of the annual Convention of the Events (COP) of the United Nations Framework Conference on Local weather Change (UNFCCC) led small states to take authorized motion. The COP conferences have been lengthy on guarantees however brief on significant deliverables. In 2021, on the sidelines of COP26, Antigua and Barbuda and Tuvalu took the initiative to ascertain the Fee on Small Island States and Worldwide Regulation (COSIS). COSIS was mandated to leverage worldwide legislation to assist SIDS’s battle for local weather justice. The group has since been joined by a number of different small states, motivated by the failure of world local weather negotiations and their disproportionate vulnerability to rising sea ranges.
Rising sea ranges are one of the vital pressing challenges these nations face. World sea ranges have elevated by greater than 10 cm between 1993 and 2024, threatening not solely the bodily existence of islands like Tuvalu and the Maldives but additionally posing quick challenges to meals safety and displacement. Some projections point out that by 2100, 5% or extra of the land in small island states could possibly be completely submerged. With no worldwide legislation obliging different states to just accept local weather refugees, these small island nations acted urgently to guard their populations from the looming prospect of displacement.
By COSIS, 9 small island states turned to worldwide legislation for redress. Forty states and worldwide organizations participated within the ITLOS proceedings, and the 2024 opinion is predicted to set a big authorized precedent.
Whereas advisory opinions usually are not immediately enforceable, they supply authoritative interpretations of worldwide obligations. In follow, such rulings create authorized precedents influencing how future circumstances are judged in world and home authorized methods. The ITLOS opinion not solely shapes the understanding of local weather obligations beneath UNCLOS however might additionally present the muse for future compensation claims from affected nations in opposition to vital emitters.
This opinion has already discovered broader utility in different important circumstances.
In January 2023, Chile and Colombia requested an opinion from the Inter-American Courtroom of Human Rights on state events’ obligations beneath the American Conference on Human Rights, particularly concerning the influence of local weather change on human rights such because the rights to life, the rights of youngsters, future generations, and indigenous communities.
4 months later, in April 2023, Vanuatu spearheaded efforts that resulted in a UN Common Meeting decision requesting an advisory opinion from the Worldwide Courtroom of Justice (ICJ).
This request sought readability on states’ obligations beneath worldwide legislation, together with the UN Constitution, the UNFCCC, and the Paris Settlement, concerning the authorized penalties for states which have triggered vital hurt to the local weather and atmosphere, significantly for susceptible states and future generations.
The ITLOS opinion may strain industrialized nations into extra formidable local weather commitments by highlighting their authorized obligation to mitigate hurt. States could face growing litigation from susceptible international locations looking for reparations or extra vigorous mitigation efforts primarily based on this authorized groundwork.
There’s additionally potential for utilizing coal and oil and gasoline producing firms, that are accountable for a big share of world greenhouse gasoline emissions and local weather change. A current report reveals that 57 oil and gasoline firms are accountable for 80% of world carbon dioxide emissions. These firms have continued to broaden fossil gasoline manufacturing even after the signing of the Paris Settlement. Therefore, there’s a name by many small island states for a world levy on them to pay compensation for harm.
This potential for actionable authorized penalties makes the ITLOS opinion greater than symbolic—it establishes a important hyperlink between authorized ideas and sensible local weather motion, pushing world powers towards higher accountability.
Worldwide legislation acts as each a protect and a weapon for small states confronting existential threats. The success of the ITLOS Opinion demonstrates the potential of authorized motion in securing local weather justice. For that reason, small states ought to unite to totally leverage worldwide legislation in addressing the profound impacts of local weather change—rising seas, shifting borders, meals insecurity, and the displacement of their populations.
When main greenhouse gasoline emitters act to avoid wasting themselves, these islands could already be lowered to mere rocks, unable to say nationhood or maintain their populations.
