During my stay at EUI in Florence, on 22 October 2025 I gave a presentation at EUI Visitors’ Seminar on „From Fragments to Framework: The ICJ as Architect of a Harmonious International Climate Law Framework and the Judicial Function“, based on a paper with Denise Köcke.

Many thanks to Pierre-François Mercure and Judith Van Veldhuizen, as well as the other participants, for their insightful and valuable comments!
