ECE’s overarching vision is to provide evidence-based, scientific roadmaps for feasible systems transformations that simultaneously meet the Sustainable Development Goals (SDGs) and ambitious climate change mitigation targets.

Emphasis is placed specifically on local policy decisions and actions required in the short term to put the world on track to achieve long-term targets while assuring human health, wellbeing, and the reduction of social inequalities in a socially and economically sustainable manner. The program’s systems analytical tools enable it to act as an objective scientific broker in support of sustainable transformational processes. ECE combines the research portfolios of the former Air Quality and Greenhouse Gases, Energy, and Transitions to New Technologies programs.

The ECE program is organized in four Research Groups which encompass different thematic areas of research:

ECE Research Groups

Integrated Assessment and Climate Change (IACC)

The IACC Group leads the development of tools for a new generation of “coupled” global transformation pathways that are able to represent bottom-up local constraints and opportunities at the national and sub-national scale, which is a major focus of the ECE Program.

Integrated Climate Impacts (ICI)

The ICI group focuses on advancing the understanding of physical climate impacts and risks in a scenario context, and their societal and economic consequences.

Pollution Management (PM)

The PM Group focusses on solving immediate and near-term environmental (health and ecosystems impacts from pollution), climate (non-CO2 greenhouse gases), and social (widening inequality gaps) problems in a cost-effective way, providing support to policymaking at local and regional scales.

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.

Transformative Institutional and Social Solutions (TISS)

The TISS Group explores innovative solutions to environmental issues that integrate social, institutional, and governance drivers with technological and economic considerations, with an emphasis on improving conditions for the most deprived and marginalized in society.

Mapping global rooftop growth for sustainable energy and urban planning

A novel machine learning framework developed by IIASA researchers to estimate global rooftop area growth from 2020 to 2050 can aid in planning sustainable energy systems, urban development, and climate change mitigation, and has potential for significant benefits in emerging economies.

Drowning in waste: pollution hotspots in aquatic environments

A new IIASA study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

Supporting the right small changes can have big impacts

Small changes in our everyday actions can trigger significant, rapid societal shifts especially when it comes to climate action. A new IIASA-led study highlights the importance of analyzing these dynamics with a comprehensive framework to harness their full potential for reducing carbon emissions.
