“Sustainability is not a destination we can reach, but a journey we must take together.” Ban Ki-moon, Former UN Secretary-General

For the fourth edition of ERFA DAY, we are shining a spotlight on the best sustainable practices in the Swiss hospitality industry across six key areas: electricity, heating and cooling, water, waste management, mobility, and nutrition.

Whether you’re running a hostel, managing an SME hotel, or leading a large hotel, taking conscious action toward a climate-friendly future is a responsibility we all share. No matter if you’re just starting your net-zero journey or already paving the way, ERFA DAY will provide you with valuable insights to keep progressing.

You’ll hear from industry experts, including representatives from the Bundesamt für Umwelt and sustainability specialists from Ernst Basler + Partner, as they share their perspectives on these critical topics and the future of a sustainable Switzerland.

Interactive workshops and stimulating activities await you, offering practical tools and fresh understanding to help us collectively move toward a net-zero future.

We look forward to welcoming you on June 3, 2025, to connect with the Swiss hotel community and explore concrete actions to continuously enhance your sustainable strategies.
