Ecological economists need to pull all sorts of leverage points to enable a just future in which the economy flourishes within planetary boundaries. One of the leverage points that is receiving increasing attention is climate and nature litigation. But what do we as community need to know about climate litigation, historical responsibility for climate change, and how litigation works in practice? We welcome Dr Benjamin Franta onto the show to discuss all things related to climate litigation. Ben is the founder and director of the climate litigation lab at the Smith School for Enterprise and the Environment at the University of Oxford. Hosted by Sophus zu Ermgassen. Edited by Aidan Knox.
