SWICE (Sustainable Wellbeing for the Individual and the Collectivity in the Energy transition) aims to answer: how to improve wellbeing for all with a much lower energy use? Wellbeing is a state of thriving, which involves full participation in society, a sense of prosperity and of leading a good life, based on the precondition of all needs being satisfied. Sustainable wellbeing extends this wellbeing to future generations. The concept of human needs is central to wellbeing, and the only approach that can define wellbeing in a broad culturally meaningful way, relevant now and far in the future. This common framework is developed to facilitate collaboration within SWICE.
