Becoming Certified as a Sustainable Hotel/Accommodation

Increasingly, travelers and your fellow travel provider clients are seeking confirmation that sustainability practices are in place ( Sustainability Report 2021). Also increasingly, travel companies are looking for a product that is not only certified sustainable, but certified sustainable by a Certification Body that is GSTC Accredited (Trivago recommendation).

Being certified by an Accredited Certification Body means that your tourism product or service complies with the highest social and environmental standards on the market. As public concern grows about the harmful effects and the positive impacts of travel and tourism, certification provides you a credible solution to complex environmental and social issues.

Travel providers should proudly display information regarding their certificate and the certification body that issued it. Doing so informs your stakeholders — from customers to ownership and to your supply chain — that your business is operated with sound management that looks to the future and not merely at today. Businesses certified by an Accredited CB can use the GSTC logo along with the Certification Body’s mark.

Many owners and buyers of hotel spaces use the GSTC framework and highlight those accommodations certified by GSTC Accredited CBs. Here are a few of them:

  • Hilton: “We continue to identify opportunities to achieve GSTC certification for our hotels to ensure the sustainability of our operations.”
  • TUI Group “encourages all hotels offered to its 27 million customers to obtain certification that meets the GSTC Criteria.”
  • easyJet holidays “is focused on supporting tourism destinations by committing to encouraging 100% of its contracted hotels to achieve certification by a GSTC-Accredited Certification body […] by the end of 2025.”
  • AMEX GBT “will highlight hotels and other accommodation partners as “sustainable” that meet GSTC’s standards or, even better, are certified by a GSTC-Accredited Certification Body.”
  • is currently highlighting hotels certified by GSTC-Accredited CBs along with other standards that are Recognized by GSTC.

How to become certified as a Sustainable Hotel

To become certified, travel and tourism companies and touristic destinations must:

1 – Choose a Certification Body (CB) from the list below — these are organizations that have been accredited based on the quality of their certification process

2 – After working with a CB towards achieving full GSTC requirements compliance, your operation will receive its Certification by an Accredited CB.

The Certification Bodies listed below have gained Accreditation to certify hotels as sustainable. As such, these Certification Bodies and their certificate-holders are authorized to display the designated GSTC Logo (upon completion of a licensing agreement with the GSTC).

To be clear: GSTC does NOT certify anything. GSTC provides accreditation to Certification Bodies through our partner ASI, Assurance Services International. Certification and accreditation are different things.

  • The above Certification Bodies have been Accredited for compliance with the requirements of the Manual for GSTC Accreditation. GSTC-Accredited mean that the certification procedures largely meet international standards for transparency, impartiality, and competence.
  • Certification by a Certification Body whose standard is “GSTC Recognized” does NOT carry the same meaning as certification by a Certification Body that is accredited by GSTC. “GSTC Recognized” relates to a published set of standards and NOT to the process of certification or accreditation.
