Sustainable Service Systems (S3)

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.

Why we must avoid temperature overshoot

A new international study coordinated by IIASA shows how near-term mitigation can help to prevent an overshoot in global temperatures, thereby reducing climate risks and bringing long-term economic gains.  More

Exploring pathways to reduce the economic and environmental risks of climate change

Allowing global temperatures to rise beyond maximum thresholds and then trying to bring them back down again through mitigation strategies is risky. A new study by an international team of researchers explored the physical and macroeconomic impacts associated with mitigation pathways with different levels of temperature overshoot.  More

The Indus basin: untapped potential for long-term energy storage

Hydropower has massive potential as a source of clean electricity, and the Indus basin can be a key player in fulfilling long-term energy storage demands across Africa, Asia, Europe, and the Middle East. IIASA researchers explored the role the Indus basin could play to support global sustainable development.  More

What Facebook can tell us about dietary choices

Lifestyle changes for demand-side climate change mitigation is gaining more and more importance and attention. A new IIASA-led study set out to understand the full potential of behavior change and what drives such changes in people’s choices across the world using data from almost two billion Facebook profiles.  More

Limiting climate risks for finance: Central banks and science publish scenarios

To improve climate related risk management in the financial sector and facilitate a smooth transition toward a sustainable economy, IIASA researchers joined forces with other scientists and a network of over 60 central banks and financial market supervisors to publish an updated set of scenarios. They show early greenhouse gas emissions reductions can minimize both physical and financial risk - in contrast, delayed action or no action would drive up costs.  More

New framework to enhance national climate action and achieve global goals

With the COP Climate conference in Glasgow only a few months away, the ambitions of the Paris Agreement and the importance of taking action at the national level to reach global climate goals is returning to the spotlight. IIASA researchers and colleagues have proposed a novel systematic and independent scenario framework that could help policymakers assess and compare climate policies and long-term strategies across countries to support coordinated global climate action.  More

Accounting for finance is key for climate mitigation pathways

A new study published in the journal Science, highlights the opportunity to complement current climate mitigation scenarios with scenarios that capture the interdependence among investors’ perception of future climate risk, the credibility of climate policies, and the allocation of investments across low- and high-carbon assets in the economy.  More

Is it worth investing in solar PV with batteries at home?

Solar energy is a clean, renewable source of electricity that could potentially play a significant part in fulfilling the world’s energy requirements, but there are still some challenges to fully capitalizing on this potential. Researchers looked into some of the issues that hamper the uptake of solar energy and proposed different policies to encourage the use of this technology.  More
