Interdisciplinary cooperation between specialised units is essential for an agile company. Thanks to modern means of communication, Skyguide is able to reduce business travel to a minimum while still ensuring communication between its 14 locations. The employees have 40 video conference rooms equipped with Skype for Business to hold web conferences. Operations permitting, working from home can also reduce travel costs. In the second half of the year, the employees in Switzerland did not travel by air but by train. These measures reduced the number of journeys by air by 1,000 units, which corresponds to a reduction in CO2 emissions of 80 tonnes.
