Responsibility and sustainability
Energy, climate, food, future cities and the handling of complex risks are all topics of global importance in which ETH Zurich has established itself as an international centre of excellence.

Most ETH departments and a growing number of competence centres are researching and creating solutions to ensure the sustainable development of our society.
In the field of energy, ETH Zurich has contributed significantly to implementation of the Federal Council’s Energy Strategy 2050. ETH is leading three of the eight Swiss Competence Center for Energy Research (SCCER) centres: external pagepower supplycall_made, energy efficiency in industry and external pagemobilitycall_made. Under the umbrella of the Energy Science Center, researchers from engineering, the natural sciences and social sciences are working together on renewable energies and their integration into the energy infrastructure, and on sustainable business models for the energy sector.
In climate research, ETH Zurich is working with partners to set up the external pageSwiss Polar Institutecall_made; it also operates the external pageNational Centre for Climate Servicescall_made (NCCS). Competencies relating to climate simulation and the modelling of its future development are combined in the Center for Climate System Modelling (C2SM). Climate scientists and researchers from various departments are also investigating how climate change affects ecology, the economy and society. ETH climate experts are involved as authors in the Intergovernmental Panel on Climate Change (IPCC) reports.
Research at the World Food System Center (WFSC) contributes to long-term food security. Agricultural, environmental and nutritional scientists are working with industry partners to develop innovative approaches to the question of how the world’s growing population can be sustainably and consistently supplied with high quality, healthy food. This requires environmentally friendly and robust production systems.
In the field of high density urban area development, ETH Zurich researchers at the Singapore ETH Centre are investigating the progress of sustainable urban development under different cultural, climate and economic conditions. The Future Cities Laboratory brings researchers from different disciplines together with designers and architects.
ETH takes a systematic and interdisciplinary approach to addressing the potentially enormous impact of global risks. The ETH Risk Center combines competencies from eight departments. The Future Resilient Systems project at the Singapore ETH Center examines how critical infrastructures can be better protected in modern, innovation-driven companies. The expanded Zurich Information Security & Privacy Center (ZISC) researches information security.
News on sustainability
How climate change is altering the Earth’s rotation
![Blocks of ice in the water](/en/news-and-events/eth-news/news/2024/07/how-climate-change-is-altering-the-earths-rotation/_jcr_content/pageimages/imageSmall.imageformat.contentteaser.989580216.jpg)
When the Earth’s ice masses melt, the way the planet rotates also changes. Researchers at ETH Zurich have now been able to show how climate change is altering the Earth’s axis of rotation and the length of the day. The speed of rotation, which was hitherto mainly influenced by the moon, will now also depend much more on the climate.
Mining rare earth metals from electronic waste

ETH researchers are developing a process inspired by nature that efficiently recovers europium from old fluorescent lamps. The approach could lead to the long-awaited recycling of rare earth metals.
Light green hydrogen will do

Whether sustainably produced hydrogen needs to be 100 percent green is currently under debate. Using the production of ammonia and artificial fertiliser as examples, researchers have calculated that "nearly sustainable" hydrogen would be better in the end.
