at the heart of
your event

We are committed to working with all of our clients and suppliers to ensure that 100% of our events are sustainable.

A sustainable event is one that aims to reduce its impact on the environment and create positive economic and social impacts.

  • Environment: mobility of participants and employees, energy and water consumption, catering choices, waste reduction
  • Social: positive impact on the EPFL community, STCC employees and society in general
  • Economic: procurement of materials and services from local and responsible suppliers
