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. Businesses certified by a GSTC-Accredited Certification Body, meeting all the GSTC Criteria (or a GSTC-Recognized Standard), have the highest level of assurance* and credibility available. With an accredited certification, customers and buyers are assured that the business was certified in a credibly verified procedure in a transparent, impartial, and competent manner.

Logo for businesses certified to the GSTC Criteria

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 a GSTC-Accredited Certification Body can display a unique GSTC logo with a traceable code.

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.”

  • is currently highlighting hotels certified by GSTC-Accredited CBs along with other standards that are Recognized by GSTC.
  • Türkiye Tourism Promotion and Development Agency (TGA) with guidance from the GSTC, has developed the first mandatory national program for accommodations based on the GSTC Criteria and GSTC Assurance program. From 2022 through 2030, all accommodations Türkiye must be certified through a GSTC-Accredited Certification Body.
  • Singapore Tourism Board announced the launch of the Hotel Sustainability Roadmap. By 2025 its goal is for 60% of hotel room stock to achieve hotel sustainability certification through a GSTC-Accredited Certification Body.
