Become Certified as a Sustainable Accommodation

Increasingly, travelers and fellow travel provider clients are seeking confirmation that sustainability practices are in place.

According to’s 2021 Sustainable Travel Report, 83% of global travelers think sustainable travel is vital. 81% of travelers say they want to stay in a sustainable accommodation, a notable increase from 62% in 2016 and 74% in 2020, just prior to the pandemic. In 2019, 62% of global travelers said that they would feel better about staying in an accommodation if they knew it had an eco-label.

Sustainability certification (what some call eco-label) is a voluntary, third-party assessment, through an audit, of an accommodation for conformity to a sustainable tourism standard, the GSTC Criteria in this case.

Many sustainability standards exist out there. Some standards focus on a specific area within sustainability like energy management or building construction, but it is important to use holistic standards that cover all aspects of sustainability in tourism.

The GSTC Criteria serve as the global standards for sustainability in travel and tourism. They are the result of a worldwide effort to develop a common language about sustainability in tourism. They are arranged in four pillars: (A) Sustainable management; (B) Socioeconomic impacts; (C) Cultural impacts; and (D) Environmental impacts.  GSTC-Recognized Standards also cover the four pillars and are equivalent to the GSTC Criteria.

The Global Sustainable Tourism Council (GSTC) does not conduct certification. Certification is conducted by relevant Certification Bodies throughout the world. GSTC accredits those that certify.

There are many organizations that offer verification and certification services, and the quality range is enormous: from rigorous, impartial and excellent, to poor. This is why accreditation of how these organizations work is crucial, a formal approval by an independent accreditation body that a certification body operates according to international standards.

Accreditation is a mark of quality that GSTC places on Certification Bodies that choose our independent and neutral process to verify that they certify businesses, in a competent and neutral manner. Some refer to it as ‘certifying the certifiers’ (Learn more about the difference between Certification, Accreditation, and Recognition).

Being certified by a GSTC-Accredited Certification Body means that your accommodation complies with the highest social and environmental standards on the market through the highest assurance level that exists.

Certified sustainable hotels should proudly display information regarding their certificate and the certification body that issued it. Doing so informs your stakeholders — from hotel guests to ownership and to your supply chain — that your accommodation is operated with sound management that looks to the future and not merely at today. Those accommodations certified by a GSTC-Accredited Certification Body can use the GSTC logo along with the Certification Body’s mark.

Many owners, distributers and buyers of hotel spaces use the GSTC framework and highlight certified sustainable accommodations. 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.

How To Become Certified

Hotels and accommodations that wish to become certified as sustainable hotels or sustainable accommodations should follow these steps:

(1) Start by using the GSTC Criteria (or a GSTC-Recognized Standard) to assess your current situation and what should be improved. There are also optional training courses about the GSTC Criteria.

(2) Choose a Certification Body (CB) from the list below. These are organizations that GSTC has accredited based on the quality of their certification process.

(3) After working with a CB towards achieving full GSTC requirements compliance, your operation will receive its Certification by GSTC-Accredited CB.

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

To clarify: GSTC does NOT certify anything. GSTC provides accreditation to Certification Bodies. Certification and accreditation are different things.

Another option is to seek verification to a GSTC-Recognized Standard

There are many sustainable tourism standards out there. The following sustainable tourism standards are GSTC-Recognized Standards, equivalent to the GSTC Criteria. This means that the GSTC Criteria are included within the set of standards owned by a certification body or a local, national, or specialized tourism organization. These sets of standards are based on the 4 pillars of the GSTC Criteria: Environment, Social, Cultural, and Management principles.

GSTC Recognition is not a mark like accreditation; rather it is a status GSTC provides to a set of standards that complies with (includes) the GSTC Criteria within their standard. This does NOT relate to the process of certification, nor to accreditation. GSTC-Recognized means that a sustainable tourism standard has been reviewed by GSTC technical experts and the GSTC Assurance Panel, and deemed equivalent to the GSTC Criteria for sustainable tourism. The GSTC has verified that the standard aligns with the GSTC Criteria and that any additional clauses do not contradict GSTC Criteria requirements.


  • This is a list of standards. GSTC has NOT analyzed the quality of the process of certification of these standards. except those that are used by GSTC Accredited certification bodies.
  • GSTC does NOT certify directly. The GSTC Criteria appear in this list to clarify the point that Certification Bodies that gain accreditation have the option to certify by using their own GSTC-Recognized standard or by using the GSTC Criteria.
