The Global Sustainable Tourism Council (GSTC) is the main international organization engaged in the promotion of sustainable tourism.
With GSTC certification, accommodation facilities can demonstrate their commitment to sustainable tourism through a credible and internationally recognized brand.
The Global Sustainable Tourism Council (GSTC) is an organization which aims to promote sustainability and social responsibility in the world of tourism.

  • Demonstrate effective sustainable management (Governance)
  • Maximize social and economic benefits for the local community and minimize negative impacts
  • Maximize the benefits to cultural heritage and minimize the negative impact
  • Maximize the benefits to the environment and minimize the negative impact

The GSTC mark is obtained through the Vireo certification service.
Vireo is a certification body accredited by ASI (Accreditation Services International) to manage GSTC certifications. This means that the GSTC certification service is evaluated and monitored by an independent third party ensuring the independence and credibility of the entire system.


In October 2021 Vireo opened operational headquarters in the Autonomous Province of Bolzano dedicated to GSTC Certification.


The GSTC certification aims to promote the concept of sustainability in the tourism sector in a practical and comprehensive way, through the implementation of basic principles and requirements which reduce the impact on the environment, highlight the local cultural heritage and optimize social and economic benefits for local communities.
When the company is ready to be audited, Vireo schedules a first certification audit (Main Assessment). In this phase, the requirements of the GSTC standard applicable to the structure are verified and, if compliance is established, a certificate is issued a few days after the audit.
he GSTC certificate has a duration of 3 years.
Hotel and resort guests are increasingly concerned about the sustainability of the services and products offered and they are aware of the need to adopt measures aimed at protecting and safeguarding the environment. The GSTC standard is internationally recognized and allows certified hotels to demonstrate their commitment to implementing and promoting a management system which is sustainable from an environmental, social and economic point of view.

Vireo is a young and dynamic certification body, able to manage any type of certification thanks to a wealth of experience and knowledge of the standards, as well as the competence and professionalism of its auditors.Companies choose us because our service is flexible, attentive and customer-focussed.
