A private estate in the canton of Vaud, in the same family for over 700 years, offering visits of its historical gardens and sculpture park, wine tourism events, as well as venue rental for weddings and corporate events. The architecture of the Château de Vullierens, the historic farm, its remarkable gardens and sculpture park make it one of Switzerland’s most outstanding cultural estates.
By 2027, 10% of our clients choose sustainability-oriented alternatives for their events, compared to 0% in 2024.*
* This is supported by an emissions calculation tool used during the planning phase and our recommendations. The tool is currently under development.
Goal 2
In progress
Internal Operations
By 2030, we reduce fossil energy consumption of the Portes des Iris building to zero (compared to no reduction in 2025) and produce more electricity than our operational needs outside of events.*
* Achieved through an energy transition including heating system replacement, solar panel installation, and building renovation.
Goal 3
In progress
Internal operations
By 2026, we reduce our non-recyclable waste by 30% (food waste, metal, plastic) compared to no reduction in 2024, and reduce by 30% our glass (water) and PET waste (water and other soft drinks) sold to clients.*
* Enabled by dedicated sorting stations by waste type, facilitating waste separation and monitoring the practices of our service providers.
Goal 4
In progress
Internal Operations
By 2025, we train 100% of our employees on sustainability best practices and organize at least two training sessions.*
* Two half-day sessions (Climate Fresk, “2 tonnes” workshop), each lasting 3 hours.
Goal 5
In progress
Supply Chain
By 2026, we raise awareness and train 100% of our caterers on sustainability best practices, and 50% of them comply with our sustainability charter.*
* One training session is offered per year. Starting with the Climate Fresk, followed by trainings related to the catering activity (food waste, product origin, etc.).
