Mobility

How much does a country's vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more "crossover" models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. Empa researchers analyze databases using deep learning methods - and can make precise statements: In which region of the country do the fattest cars drive? What can car buyers do to reduce CO₂ consumption?

Shared e-scooters and e-bikes transport the image of a climate-friendly mobility solution. ETH researchers have now shown that shared micromobility solutions in Zurich emit more CO₂ emissions than the alternatives they replace.

Noise barriers or improved wheel systems and brakes that are less noisy are not the only ways to reduce railway noise for close-by residents. An inconspicuous component under the tracks is a source of hope for a research team including Empa scientists.
