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?

Intelligent packaging with sensors that monitor goods, such as vegetables, on long transport routes is a trend for the future. Yet printed and disposable electronics also cause problems: Metals in printing inks are expensive – and disposing of them in an environmentally sound manner is costly and exacerbates the problem of electronic waste. A new solution from Empa researchers aims to remedy this.

Buildings, roads, railways, supply and disposal networks and much more: The entire Swiss built environment is as complex as its challenges for the future – due to climate change, natural hazards, population growth and other factors. Where to start? With which priorities? An expert group has launched an initiative for an overall view – and thus is giving new impetus for research and practice.

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.

Indoor air quality has an influence on how many corona virus infections occur there. This has now been shown for the first time in a pilot project involving Empa researchers in 150 primary school classrooms in Graubünden. The analysis also showed that the air quality in many classrooms is poor. The study concluded that regular ventilation of classrooms is therefore very important, even in winter months.
