Science and justice in climate litigation

In this episode of Between Heat and Hope, we are joined by Professor Joyeeta Gupta. Joyeeta Gupta is Professor of Environment and Development in the Global South at the University of Amsterdam and Professor at IHE Delft Institute for Water Education. Her work sits at the intersection of climate law, earth system science, and environmental justice, with a particular focus on the Global South. She has been involved in the Intergovernmental Panel on Climate Change

The conversation begins by unpacking the role and working methods of the Intergovernmental Panel on Climate Change, where Joyeeta has been involved as a lead author. It then turnsto the current state of climate science and the prospects of limiting global warming to 1.5°C with no or limited overshoot. Joyeeta walks us through key concepts such as carbon budgets, net zero and overshoot, and explains how these concepts shape mitigation pathways and questions of equity. From there, we discuss the role and limits of science in climate litigation. The episode then turns to North-South equity, fossil fuel phase-out, carbon lock-in, and the particular justice questions raised by climate cases in Europe and the Global South. Finally, Joyeeta reflects on her long engagement with global climate policy and on what a more sustainable and equitable future would require.

The Indirect Impacts of Climate Litigation

In this episode of Between Heat and Hope we are joined by Professor César Rodriguez-Garavito. César Rodriguez-Garavito is Professor of Law at the Center for Human Rights and Global Justice at New York University School of Law. He is the founding director of the More-Than-Human Life Program, the Earth Rights Research & Action Clinic, and the Commons on Machines, Policy, Automation & Society at NYU Law. His work focuses on international environmental law, Indigenous peoples’ rights, technology, and more-than-human rights. In 2025, Cesar published Climate Change on Trial: Mobilizing Human Rights Litigation to Accelerate Climate Action with Cambridge University Press.

The conversation explores the indirect impacts of climate litigation and the ways in which climate cases shape politics, public discourse, and the democratic process beyond the courtroom. Cesar reflects on his trajectory from socio-economic rights and socio-environmental conflicts to climate litigation and the rights of nature. Throughout the talk, we compare the development of climate litigation in Europe with experiences from Latin America and other regions of the world, discussing how different legal cultures and political contexts shape climate cases.

Drawing on Cesar’s earlier work on judicial activism and socio-economic rights, we discuss the distinction between direct and indirect effects of litigation, as well as the material and symbolic dimensions of climate judgments. We also explore the emergence of a global “litigation ecosystem,” where lawyers, scientists, activists, and communities increasingly collaborate across jurisdictions and disciplines. From the KlimaSeniorinnen judgment before the European Court of Human Rights to broader questions of standing, representation, and access to justice, the episode reflects on the democratic implications of climate litigation and the risks and opportunities of rights-based approaches to the climate crisis. Finally, Cesar shares his thoughts on the future of climate litigation and the transformative potential that climate cases may still hold.

Standing at the European Court of Human Rights

In this episode of Between Heat and Hope we are join by Professor Corina Heri. Corina Heri is Associate Professor of human rights and climate change at Vrije Universiteit Brussel and Primary Investigator of the TEMPORALAW project. In this capacity she works on human rights law, climate change, the role of courts as well as the role of vulnerability in the law.

The conversation sets out discussing climate litigation before the European Court of Human Rights and particularly looks at different questions related to access to court and what kind of applicants can and should bring climate cases. Corina walks us through her critique of climate litigation exclusively being brought by associations as flattening the claims that can be made that way. From KlimaSeniorinnen we look to the wider set of climate cases before the ECtHR and discuss how Duarte Agostinho, Greenpeace Nordic, and possible the pending case Müllner v Austria fit into the puzzle and what they tell us about the Court’s approach to the climate crisis. Corina also shares some more structural insights on the functioning of the Court in relation to its narrative of limited resources and how that impacts its treatment of climate cases. Finally, we get a taste of the questions Corina’s new project TEMPORALAW will investigate.
