The S3 Group focuses on demand-side systems as entry points for sustainable transformations. The group analyses demand for energy and materials through the lens of service provision of mobility, shelter, and consumer goods, as well as how lifestyle changes can contribute to consumption reduction.

The S3 Group have two overarching research objectives. First, to understand the evolution of behaviors and lifestyles around energy services and assess their environmental impacts; and second, to identify and understand policy interventions that can change behaviors and lifestyles to minimize environmental impacts. The group’s research binds together work on three domains that are critical for a transformation toward sustainable societies, namely buildings, mobility, and consumer goods, which are connected through changes in infrastructures and lifestyles. S3 aims to establish and lead a research community on demand-side transitions and to innovate conceptual frameworks for demand-side model comparisons.

Feasible futures

Policy Brief #41, October 2023. Embracing the notion of feasibility, this research shows that the world will probably overshoot 1.5°C, largely owing to low institutional capacity. Energy demand reduction and electrification are two options to turn down the heat, and addressing weak institutions is crucial.
