In sum, the United States is undoubtedly at the top of the list of potential defendants against climate change suits brought by environmental lawyers and academics, native peoples such as the Inuit, and UNCLOS states parties such as Tuvalu. Moreover, UNCLOS’s compulsory dispute resolution tribunals are regularly cited as viable international forums for bringing an international climate change action against the United States.101
Thus far, the United States has denied potential climate change claimants their day in international court by withdrawing from compulsory ICJ jurisdiction and by refusing to accede to UNCLOS. Clearly, accession to the convention would open the door to these litigants as well as to their advocates in the international academic, environmental, and nongovernmental organization communities.
In sum, by acceding to UNCLOS the United States would unnecessar- ily expose itself to baseless environmental lawsuits, including a claim that its GHG emissions have caused harm to other nations. Because of its membership in the convention, the U.S. could be compelled to appear before a tribunal to defend itself in any such lawsuit. International courts and tribunals, including those created by UNCLOS, have not hesitated to assert jurisdiction and pass judgment in controversial social, political, and environmental lawsuits. The judgment of an UNCLOS tribunal in a climate change lawsuit would be final, unappealable, and enforceable in the United States.
The domestic enforceability of UNCLOS tribunal judgments was confirmed by U.S. Supreme Court Justice John Paul Stevens in Medellin v. Texas, a landmark case in 2008.27 In Medellin, Justice Stevens, writing in a concurring opinion, cited Article 39 of Annex VI for the proposition that UNCLOS members—presum- ably including the United States if it accedes to the convention—are obligated to comply with the judgments of the convention’s tribunals. The Medellin case concerned whether the ICJ’s judgment in 2003 against the United States in the Case Concerning Avena and Other Mexican Nationals (the Avena case) is domestically enforceable. Justice Stevens concluded that the relevant treaties in the Avena case—the U.N. Charter and the Vienna Convention on Consular Relations (VCCR)—did not require the Supreme Court to enforce the ICJ’s ruling. Justice Stevens contrasted the permissive language of the U.N. Charter and the VCCR with the explicit language of UNCLOS and concluded that the convention would indeed oblige the Supreme Court to enforce the judgments of UNCLOS tribunals within the United States.28
If the United States received an adverse judgment in an UNCLOS climate change lawsuit, the tribunal could order remedies similar to those imposed by the Trail Smelter tribunal—a regime of regulations, compli- ance measures, and even reparations. In anthropogenic climate change parlance, such a regime would be akin to mitigation measures (i.e., actions to reduce the level of U.S. GHG emissions).
A comprehensive GHG mitigation regime imposed on the U.S. would seriously affect the American econ- omy because carbon emissions and other GHG are produced throughout the United States by several signifi- cant sectors of the economy, includ- ing the electricity generation, transportation, industrial, residential, and commercial sectors. Like the “cap-and-trade” regulations that have been debated in Congress, the imposition of international Trail Smelter– style regulations on every U.S. power plant, refinery, automobile, chemical plant, and landfill would harm the U.S. economy.118
A claimant in a climate change lawsuit against the United States would face several legal and evidentiary challenges in proving its case in an UNCLOS tribunal, including jurisdictional hurdles, causation issues, and the question of equitable apportionment of damages.126 Nevertheless, regardless of whether the U.S. might ultimately prevail in such a case, acceding to the convention is fraught with political danger. Advocates of international climate change lawsuits see them as an acceptable way to achieve their environmental ends, including U.S. capitulation to a comprehensive climate change treaty:
Litigation or the threat thereof would emphasise the urgency of the need to agree [to] binding commitments on climate change and would put additional pres- sure on the negotiations process. Negotiators may feel more of a responsibility vis-à-vis the international community and have an additional lever in relation to their national governments. A high-profile court case would also engage a variety of actors in the debate and provide new momentum to find consensual solutions inside and outside the UNFCCC talks ... . Inter-State climate change litigation may help to create the political pressure and third-party guidance required to re-invigorate the international negotiations, within or outside the UNFCCC.127
One law professor believes that “litigation will very likely play a role” in determining who will bear the costs of climate change and singles out the United States for special treatment, stating that “litigation efforts need to be primarily focused on the United States as the major hindrance to beginning the remedial process” (i.e., by failing to ratify the Kyoto Protocol).128 Other proponents of the theory of anthropogenic climate change understand that there are precedents for using international courts to achieve purposes other than legal redress. For instance, the World Trade Organization “has similarly been strategically employed by governments to influence negotiations and clarify State obligations.”129
Those who believe the costs of ratification outweigh the benefits, because most of the benefits are already provided by customary law, might want to consider the global state of affairs that would unfold if the 160+ nations that are already a party to the Convention—including the critical straits states—chose to follow the U.S. lead and eschew adherence to a meticulously drafted convention in favor of malleable customary law rules. While the Convention’s 320 articles and 9 annexes are not always a model of precision, one can certainly question whether the Convention ambiguities the opponents point to are any clearer under the corresponding customary law and whether rule stability is better served by a conventional regime or the practice of 160+ states.
The Convention reduces, but doesn’t wholly eliminate, the indeterminacy inherent in customary law. The Convention also provides greater stability and predictability. Here it should be noted that the LOS Convention’s articles can only be amended through an elaborate process that, by design, provides the kind of stability the U.S. has long sought in the maritime domain. By contrast, customary law rules evolve by the practice of nations asserting, acceding to or persistently objecting to new norms, thus introducing unwelcome uncertainty into the nation’s maritime affairs. Moreover, as Edwin Williamson, President George H.W. Bush’s State Department Legal Advisor noted, the history of customary international law “reflects a steady deterioration of the freedom of the seas to the detriment of the essential rights of maritime nations, such as the U.S.”
