sustainable leadership in hospitality

CSR and ISO 20121

our purpose

CSR at bnetwork goes beyond rhetoric; it is a critical mission we take to heart. our approach is about embodying a commitment to the planet and its people.

we have held ISO 20121 certification since december 2024 and transitioned to ISO 20121:2024, the second edition of the standard, in december 2025.

180 colleagues across our offices contribute to the implementation and continuous improvement of the management system.

our strategic approach aligned with ISO 20121

we reviewed more than 50 sustainability labels and recognise only those we can verify - among them Green Key, EarthCheck, EU Ecolabel, ISO 14001 and ISO 50001. an annual partner survey lets hotels submit credentials, which our consultants check before they reach our booking sites.
