ISO 140001
The international standard for implementing an environmental management system (EMS), ISO 14001, provides companies with a concrete tool for doing so. This standard can be used to create the conditions for continuous improvement of an organisation's environmental performance.
Since 2021, both Castello del Sole and Storchen Zürich have been proudly ISO 14001 certified – traditional establishments that successfully unite timeless savoir-vivre with a strong commitment to environmental sustainability.
