More than a Sink

The difference between treating the oceans as a mere sink versus protecting them as a vital part of the environment has important implications under international law. These implications come to the fore when considering the relationship between the UNCLOS on the one hand and the UNFCCC and its Paris Agreement on the other. While the latter treaties in no way legitimize pollution of the marine environment, their focus on oceans as sinks could be misinterpreted to deprive UNCLOS and the customary rules it codifies of a meaningful role in addressing climate change.

Why Climate Science Matters for International Law

The International Tribunal for the Law of the Sea (ITLOS) issued an advisory opinion on May 21, 2024 in response to a request submitted by the Commission of Small Island States on Climate Change and International Law (COSIS). While various aspects of the advisory opinion have already been discussed in this joint blog symposium, this post focuses on a feature of the opinion that has so far received little emphasis: the strong role of science. The scientific evidence presented by the tribunal provides a solid basis for its conclusions on State obligations to prevent, reduce, and control climate pollution.

Finding Light in Dark Places

Can the new advisory opinion interpreting the United Nations Convention on the Law of the Sea (UNCLOS) move us beyond the lethargy of unmet climate change policy needs? The International Tribunal for the Law of the Sea established the gravity of this question by stating that “climate change represents an existential threat and raises human rights concerns”. The Tribunal acted both boldly and conservatively by interpreting UNCLOS as an independent source of international legally binding obligations to address climate change and ocean acidification.

ITLOS and the importance of (getting) external rules (right) in interpreting UNCLOS

The Advisory Opinion handed down by the International Tribunal for the Law of the Sea (ITLOS) on 21 May 2024 is truly remarkable. However, while ITLOS succeeded in noting the relevance of many other treaties and customary norms in international law, it fell short of a comprehensive and consistent approach to determining which other treaty norms would be relevant to the interpretation of UNCLOS and how. Establishing coherence by “taking into account external rules” means more than a general reference or a pick-and-choose approach to some relevant norms in an external treaty, while not to others.

A Small But Important Step

While no advisory opinion can solve the climate crisis, the ITLOS decision does provide an important push for action, both globally and at the national level. It cleared the way for the ICJ’s forthcoming opinion on climate change, demonstrating how a clear and solid line of arguments can be developed. Although the ICJ may decide differently due to variations in the questions posed and treaties interpreted, it is unlikely to diverge significantly from the ITLOS narrative or reject its findings on related topics.

Consensus, at what Cost?

After four applications for provisional measures, three sets of formal orders and two rounds of oral hearings, on Friday night, the International Court of Justice in South Africa v. Israel delivered a long-awaited Order. It is, to be frank, most unsatisfactory. While the Court is known for its “Solomonic” decisions, which try to give each party a little of what they asked for at times to no one’s satisfaction, this is not a maritime boundary delimitation where equidistance can be imposed in pursuit of impartiality.

The ITLOS Advisory Opinion and Marine Geoengineering

The ITLOS advisory opinion does little to resolve the long-standing uncertainty regarding the legal status of marine geoengineering activities. On the contrary, the opinion raises more questions than it answers. ITLOS seems content to leave those questions to others. Indeed, in the advisory opinion, ITLOS noted that “marine geoengineering has been the subject of discussions and regulations in various fora,” including the London Convention and Protocol. But after nearly twenty years, the regulatory framework for marine geoengineering adopted by the parties to the London Convention and Protocol is still not, strictly speaking, legally binding. Perhaps the advisory opinion will spur the parties into action.

Unlocking UNCLOS

By advancing a more holistic vision of climate-relevant international law—one that seeks to harmonise but also allow for complementary interaction amongst the obligations set under different regimes—the ITLOS advisory opinion offers hope. It holds out the promise of a synergistic international legal response to climate change that better maps to the integrated and interconnected nature the ecosystems at stake and to the multi-pronged regulatory effort that will be needed to safeguard our climate system.

The ITLOS Advisory Opinion on Climate Change

On May 21, 2024, the International Tribunal for the Law of the Sea (ITLOS) delivered a long-awaited Advisory Opinion on climate change and international law. This marks the first time that an international tribunal has issued an advisory opinion on State obligations regarding climate change mitigation. The Advisory Opinion addresses several key questions regarding application of the United Nations Convention on the Law of the Sea (UNCLOS) in the context of climate change. There is much to explore in terms of both the content of the ITLOS advisory opinion and its potential implications for global, regional, and local efforts to combat climate change. To facilitate discussion and the exchange of ideas, the Sabin Center's Climate Law Blog and Verfassungsblog are partnering on a blog symposium on the ITLOS opinion. In this first, introductory blog, we outline the background to the advisory opinion and highlight some of the key takeaways from it.

Anträge mit Sprengkraft

Am 20.5.2024 hat der Chefankläger des Internationalen Strafgerichtshofs bekannt gegeben, dass er in der „Situation Palästina“ mehrere Haftbefehle gegen ranghohe politische und militärische Führungspersonen beantragt hat. Dass der Ankläger zeitgleich gegen Mitglieder der Hamas und der israelischen Regierung vorgeht, bedeutet nicht, dass er eine Terrorgruppe mit einer demokratisch legitimierten Regierung gleichsetzt. Er bringt vielmehr zum Ausdruck, dass das Völkerstrafrecht für alle Konfliktparteien gilt und bemüht sich um einen ausgewogenen und (soweit in diesem Konflikt überhaupt möglich) neutralen, zumindest entpolitisierten Ansatz. Damit wird der Grundstein für eine gleichmäßige Anwendung des Völkerstrafrechts gelegt.
