The climate trial: law and justice on a melting planet
In May 2025, a German court ruled for the first time anywhere in the world that major corporate emitters can in principle be held liable for their contribution to climate change harms. The case — Lliuya v. RWE — made headlines globally. But the full story of how this landmark lawsuit was built over a decade has never been told.
Join us for the launch of The Climate Trial, a new book by Noah Walker-Crawford that provides the first inside account of one of the most significant climate lawsuits ever brought. Walker-Crawford helped initiate the case in 2014, served as interpreter and scientific adviser to the plaintiff's legal team, and went on to study the lawsuit as an anthropologist. The result is a book that moves between German courtrooms, UN climate summits, and melting glaciers in the Peruvian Andes, revealing what climate justice looks like in practice: the legal strategy, the science, the corporate response, and the deeply personal motivations of a Peruvian farmer who stayed the course for a decade because he felt the mountains were suffering.
The event will open with introductory remarks from LSE's Mareike Winchell, followed by a video message from Saúl Luciano Lliuya, the plaintiff in the case, and a presentation from the author. A panel of respondents will then explore the book's themes from the perspectives of law, climate science, and anthropology, followed by an open discussion with the audience.
The panel brings together people with direct connections to the book's subject matter: Roda Verheyen, the lawyer who represented Luciano Lliuya throughout the case; Friederike Otto, whose field of climate change attribution science was at the centre of the evidentiary arguments in the courtroom; and Hannah Knox, whose anthropological work on climate and environmental governance speaks directly to the book's analysis. The discussion will be chaired by Joana Setzer, a leading researcher on climate litigation.
Following the discussion, guests are welcome to join a reception where they can collect copies of the book and have them signed by the author.
