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

At Biosphere Responsible Tourism (BRT) we assess and certify the conformity of sustainability practices in businesses and territorial tourism managers ‘destinations’, whatever their size or location: hotels, restaurants, museums and many other types.

We currently work under the Biosphere Scheme of the Responsible Tourism Institute (RTI), 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 required to assess it.

Once the outcome is favourable, your entity's certification will be available in our public web repository, where anyone interested can check the scope and validity of your certification. In this way, you provide clear and assessed information to customers, visitors, investors and the rest of your stakeholders.
