The Global Sustainable Tourism Council (GSTC) is an independent organization established in 2007 by UNEP, the United Nations Environment Program, and UNWTO, the United Nations World Tourism Organization, for promoting the increased knowledge, understanding and adoption of sustainable tourism practices.
With GSTC certification, destinations can demonstrate their commitment to sustainable tourism through a credible and internationally recognized brand.
Obtaining GSTC certification is the most prestigious achievement for tourist destinations that make sustainability a fundamental element of their offer.

The GSTC criteria are recognized worldwide and are developed around four fundamental concepts:

  • Sustainable Management (Governance)
  • Socio-economic sustainability
  • Cultural sustainability
  • Environmental sustainability

The GSTC mark is obtained through the Vireo certification service. Vireo is a GSTC accredited certification body. This means that the certification service is carried out and managed according to the accreditation standard, which defines methods, procedures and timing for verification audits, 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 destination is ready to carry out the verification, Vireo schedules a first certification audit (Main Assessment). In this phase, the requirements of the GSTC standard applicable to the destination are verified and, if the verification is successful, the certificate is issued a few days after the verification.
he GSTC certificate has a duration of 3 years.
GSTC certified destinations can promote their status by using the GSTC logo on their website and promotional materials, distinguishing themselves and publicizing their commitment to implementing a sustainable asset management system
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.
