Building sustainable models
and recognizing good practices


Biosphere® is the international system worldwide for applying continuous improvement processes, connected in real time with the United Nations 17 SDGs and 169 targets, and with indicators developed with the UN-SDSN.

Created by the Responsible Tourism Institute (RTI), Biosphere is the unique sustainability management and certification methodology for companies and destinations, where their sustainable efforts are connected, publicly valued and guaranteed with universally recognised criteria.

With a 100% digital methodology and management platform, at Biosphere we involve and mobilise all stakeholders for a real commitment to sustainability. Communicating in 9 languages, we have created a global community, with thousands of companies and destinations where people share experiences and good practices, between different sectors and realities, under a common language.

Biosphere represents the universal homogenising and facilitating system, with close connection to official or UN-related bodies, to implement continuous improvement processes that integrate all international sustainability criteria and standards.

Biosphere was the first methodology in the world to address socio-cultural, as well as environmental and economic aspects in sustainability management and certification processes. It was also the first to be applied at destination level on an international scale, and the first to certify sustainability with its three fields in the hotel accommodation sector in 1997.

After more than 25 years of being applied in companies and destinations all over the world, Biosphere is recognised as the best sustainability management and recognition tool in the world, as stated in the international report drawn up by the University of Sherbrook and Tourisme Durable Quebec.

More than 55 destinations around the world work with Biosphere to align their public policies and business models with the objectives and principles of the United Nations, and it is a system chosen by more than 4,000 companies from 77 different countries.

The bodies behind Biosphere

Responsible Tourism Institute (RTI)

BIOSPHERE© certification is awarded by the Responsible Tourism Institute (RTI), an independent body created in 1997 with the aim of promoting sustainable development actions and programmes in tourism destinations and companies. With more than 25 years of experience in the sector, the RTI was created with the support of UNESCO through a Memorandum of Understanding that has enabled the development of activities, projects and cooperation events between the two organisations. It is also a founding member of the Global Sustainable Tourism Council (GSTC).

A pioneer in the sector, Biosphere was the first sustainability certification system to incorporate social and cultural issues (1998), the first system able to recognise and value the sustainable efforts of a destination worldwide (2009) and the first to develop an online certification process (2015). Since 2017, the Responsible Tourism Institute's system has been chosen as the best sustainability certification tool, constituting the only methodology to align the practices of destinations and companies jointly and with the 2030 Agenda, its 169 goals and 17 Sustainable Development Goals (SDGs).
