More than a certification: a process of continuous improvement involving external and independent audits

At Biosphere Responsible Tourism (BRT) we assess and certify compliance with sustainability actions in companies and tourism–territorial managers «destinations», whatever their size or location: hotels, restaurants, museums, among many other typologies.

We currently work under the Biosphere Scheme of the Responsible Tourism Institute (ITR), through our own platform, Biosphere Sustainable, where you will complete your certification process independently: you will be able to consult your documentation at any time and receive, 100% online, the external audits needed to verify it.

Once verified, your actions are published on our public web repository, where anyone interested can check the scope and validity period of your certification. This way, you provide clear, verified information to customers, visitors, investors and the rest of your stakeholders.
