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.

Identifying global poverty from space

Despite successes in reducing poverty globally in the last two decades, almost one billion people are still living without access to reliable and affordable electricity, which in turn negatively affects health and welfare, and impedes sustainable development. Knowing where these people are is crucial if aid and infrastructure are to reach them. A new IIASA-led study proposes a novel method to estimate global economic wellbeing using nighttime satellite images.

The concept of nexus thinking has gained traction amongst the applied research community to examine cross-sector linkages between land, water, and energy strategies. A nexus approach identifies the interactions among sectors to better understand the synergies and trade-offs involved in meeting future resource demands in a sustainable way.
