Study Identifies European Cities with Highest Mortality Due to Air Pollution
Study Identifies European Cities with Highest Mortality Due to Air Pollution
A health impact study has for the first time estimated the mortality burden attributable to air pollution in more than 1,000 European cities. The study, published in The Lancet Planetary Health, includes a ranking of the European cities with the highest rates of mortality attributable to each of the two air pollutants studied: fine particulate matter (PM2.5) and nitrogen dioxide (NO2).

Modelling the energy transition
Modelling the energy transition
An interdisciplinary research team from ETH Zurich is developing the Nexus-e modelling platform in a project supported by the Swiss Federal Office of Energy. The platform facilitates the analysis of how technological, economic and regulatory developments affect the energy system of the future. Switzerland's energy system will undergo a fundamental transformation in the coming years.

Changing resilience of oceans to climate change
Changing resilience of oceans to climate change
Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. An international team of scientists led by ETH Zurich used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago - and found limited expansion of seafloor anoxia (absence of oxygen).

How will we achieve carbon-neutral flight in future?
They emit must be systematically stored underground. This is the most economical of various approaches that ETH researchers have compared in detail. It is politically agreed and necessary for climate protection reasons that our entire economy becomes climate-neutral in the coming decades - and that applies to air travel, too.

Packaging database for fact-checking sustainability promises
Packaging database for fact-checking sustainability promises
Researchers have created a database of over 3,000 primary and secondary packaging items from the range of the retailer Denner as a basis for ensuring more environmentally friendly packaging. The presents are unwrapped, the takeaway is eaten and the latest online order has arrived - and now there is packaging everywhere.

Wastewater treatment plants retain 96 percent of mercury
Wastewater treatment plants retain 96 percent of mercury
Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion's share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).
