The breaching of planetary boundaries and the accelerating impacts of climate change are prompting growing numbers of researchers to question the long‑held assumption that economic growth must be endless. This interdisciplinary symposium brings together academics from across the ������Ƶ and beyond to explore what Beyond Growth Economics might mean for economic stability, wellbeing and sustainability.

The event creates space to reflect on some of the most pressing questions facing contemporary societies: how economies might function without continued GDP growth, how innovation and productivity relate to post‑growth thinking, and whether alternative measures of wellbeing and sustainability offer more just and resilient pathways forward.

Through a combination of short research talks, a keynote address and panel discussion, the symposium will bring together diverse perspectives spanning economic modelling, policy, politics and social justice. The programme will feature a keynote presentation by Ida Kubiszewski from the Institute for Global Prosperity (University College London), followed by a panel chaired by Professor Caroline Lucas, former Green MP for Brighton Pavilion and Professor of Practice in Environmental Sustainability at the School for Progressive Futures, linking academic research with political experience and real‑world decision‑making.

Designed as an open and collaborative forum, the symposium invites dialogue across disciplines and encourages critical, constructive debate. It offers an opportunity to connect with colleagues, share emerging ideas and contribute to growing conversations about how economies can support both people and planet in a post‑growth future.
