Abstract: This seminar will report on several streams of research within the "Living Well Within Limits" project. The Living Well Within Limits project investigates the energy requirements of well-being, from quantitative, participatory and provisioning systems perspectives. In this presentation, I will communicate individual and cross-cutting findings from the project, and their implications for the physics research community. In particular, I will share our most recent results on the international distribution of energy footprints, results on the national characteristics that enable high well-being at low energy use, and modelling of universal well-being energy requirements. I will show that achieving low-carbon well-being, both from the beneficiary ("consumer") and supply-chain (producer) sides, involves strong distributional and political elements. Simply researching this area from a technical or economic lens is insufficient to draw out the reasons for poor outcomes and most promising avenues for positive change. I will connect this research to potential contributions from the physics community to some of the most important challenges humanity has ever faced.
