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. Continue reading >>

From Strasbourg to Luxembourg?
KlimaSeniorinnen has established a remedy which, in EU law, is not easy to locate and may actually be unavailable in light of restrictive CJEU case law. Whatever one’s views on this restrictive case law, it is a fact that the EU Charter of Fundamental Rights now obliges the CJEU to do as much as it can to accommodate the KlimaSeniorinnen remedy and to interpret the relevant TFEU provisions flexibly. One may assume that, sooner or later, the CJEU will be confronted with a KlimaSeniorinnen claim. If the CJEU were to declare such a claim inadmissible, it will put itself in the corner of courts refusing to engage with climate change policies. That would be unfortunate for a court that has long been at the forefront of legal progress.

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.

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. Continue reading >>

After Switzerland Comes Austria
The KlimaSeniorinnen judgment of the European Court of Human Rights (ECtHR) has been the subject of intense debate for several weeks. One focus was on the question of standing, i.e., who can bring a lawsuit connected to climate change and human rights before the ECtHR. However, less attention has been paid to the question of the impact of the judgment on currently pending climate change cases before the ECtHR. This blog post sheds light on “climate change case number four”, a case against Austria primarily challenging the shortcomings of the Austrian Climate Protection Act.

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. Continue reading >>

Climate, Constitution and Party Politics
Recent developments in Scotland in relation to climate targets have presented interesting questions for both constitutional and climate law. After proudly announcing itself as a nation with world-leading targets for reducing greenhouse gas emissions and giving these legally binding status, now that it has been realised that the 2030 target will not be reached, that target has been abandoned. In turn, this has been the catalyst for the break-up of the two-party arrangement that supported the government and the resignation of the First Minister who faced losing a vote of confidence.
