The Scenarios Forum 2025 is an influential multi-disciplinary conference organized by the Priestley Centre for Climate Futures and the University of Leeds, building on the successes of previous forums in Denver (2019) and IIASA (2022). Dedicated to advancing the use of socioeconomic scenarios in addressing some of the most complex and interconnected challenges of our time, this year’s forum is particularly timely as we navigate an era defined by rapid environmental shifts, social upheavals, and global uncertainties. The forum gathers experts from around the world to share knowledge, foster collaborations, and reflect on the use of scenarios, with a focus on identifying future research needs. This year, we are expanding our horizons to explore the transformative potential of scenarios that address health, inform policy, and open up new possibilities for the future. The need for robust, integrative scenarios has never been greater, and the Scenarios Forum 2025 aims to be at the forefront of these critical discussions.
