This document presents four scenarios for sustainable lifestyles in Europe by 2050. The scenarios are: Pandemic Technology, Meritocracy, Endemic Technology, and Human-Centrism. They explore different social models and pathways to a sustainable society through disruptive changes in lifestyles, technologies, and policies. One scenario called "Local Loops" depicts a future where high energy and food prices lead to localized communities that share resources and rely on local production to meet needs in a sustainable way through the support of "gatekeepers" and lifestyle changes. The scenarios are tools to explore potential disruptions and evaluate experiments that could accelerate progress towards sustainability.
