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.

The TISS Group specifically aims to develop more comprehensive and integrated approaches to simultaneously meeting developmental, planetary, and public health-related goals by taking a people-centered approach to sustainable development and mitigation of environmental impacts. The group investigates novel technological, social and institutional innovations to address environmental challenges with a focus on end-use services for human wellbeing, explicitly integrating distributional, equity, institutional, and governance aspects into the assessment of these novel solutions under a broader framing of transformations underpinning the Sustainable Development Goals (SDGs). Through its research, TISS endeavors to provide a basis for new innovations, new business models, and social entrepreneurship and a renewed emphasis on informing more equitable, effective, and acceptable policy design.

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.

New IPCC Report: we can halve emissions by 2030

Between 2010 and 2019, average annual global greenhouse gas emissions were at their highest levels in human history, but the rate of growth has slowed. Without immediate and deep emissions reductions across all sectors, limiting global warming to 1.5°C is beyond reach. However, there is increasing evidence of the success of climate action, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report.
