The vision of the 2019 Swiss Wrestling and Alpine Festival (ESAF) in Zug was not only to organise an atmospheric and unique sports festival but, as the largest sporting event in Switzerland, also for it to be successful from an environmental and social point of view. To achieve this goal, a sustainability department was set up for the first time and a comprehensive sustainability management was launched. The myclimate foundation supported the department in its strategic decisions, the calculation of emissions for the event and the on-site communication measures. myclimate was also involved in creating the sustainability report.
