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.

Pivotal moment for humanity as tipping point threats and opportunities accelerate

The world has reached a pivotal moment as threats from Earth system tipping points – and progress towards positive tipping points – accelerate. The just released Global Tipping Points Report – the most comprehensive assessment of tipping points ever conducted – highlights that humanity is currently on a disastrous trajectory.

New research exemplifies collaboration between IIASA and EAP

IIASA and the University of Wisconsin Madison's Energy, Analysis, and Policy (EAP) Program have a history of collaborating on impactful research and formalized their partnership in 2022 thanks in part to a generous donation from Wes and Ankie Foell. Wes Foell, EAP co-founder, completed modeling work for IIASA in the 1970’s, and hopes to see the collaboration continue to grow.

Mind the gap: caution needed when assessing land emissions in the COP28 Global Stocktake

The land use, land use change, and forestry sector plays a strong role in achieving global climate targets, but a gap exists between how scientists and countries account for its emissions. A new study highlights how mitigation benchmarks change when assessing IPCC scenarios from a national inventory perspective, with net-zero timings arriving up to five years earlier and cumulative emissions to net-zero being 15-18% smaller.
