A global study shows that the world’s groundwater resources are dwindling: levels are falling sharply worldwide, and the decline has accelerated in the 21st century. Nevertheless, there is still reason for hope.

The Federal Department of Foreign Affairs (FDFA) and ETH Zurich, in collaboration with their international partners, are launching the International Computation and AI Network (ICAIN) at the World Economic Forum (WEF) 2024 in Davos. Its mission is to develop AI technologies that benefit society as a whole, as well as being accessible to all and sustainable, thereby helping to reduce global inequality.

Researchers at ETH Zurich are developing a new method to remove CO₂ from the atmosphere. It involves molecules that become acidic when exposed to light. Their new process requires much less energy than conventional technologies.

Climate neutrality and nuclear phase-out: Switzerland's ambitious green electricity targets are realistic if the electricity supply is profoundly and rapidly transformed, as a study by the SWEET EDGE consortium shows. The researchers developed three strategies for expanding renewable energies.
