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 proudly display information regarding their certificate and the certifying 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.

Increasingly, travelers and your fellow travel provider clients are seeking confirmation that sustainability practices are in place. Also increasingly, travel companies are looking for a product that is not only certified sustainable, but certified sustainable by a certification program that is GSTC Accredited. For example, Royal Caribbean Cruises give preferential buying treatment, when feasible, to operators of shore excursions that are certified by a GSTC-Accredited Certification Body. MSC Cruises follow a similar model. Other travel providers give preferential buying treatment to suppliers that are certified sustainable.

Join the growing number of tour operators throughout the world that have become certified sustainable, here is how.

How To Become Certified: Key Stages

1. Compare and Select a Certification Body
Choose from the list below, of “Certification Bodies” that are Accredited or “Certification Schemes” that are committed to partnering exclusively with accredited Certification Bodies.

2. Register and/or Contract with a Certification Body
The Certification Body may require tour operators to officially register, fill out an application and pay a one-time fee. Some certification bodies may require tour operators to enter into a contract with the certification body. Prior to starting the certification process, some certification bodies offer the option to conduct a short self-evaluation to determine if certification is worth the time, money and effort. Costs may be associated with this step.

3. Submit Application/Documentary Evidence to the Certification Body
When ready to formally start the certification process, the tour operator will submit an application. The certification body will request information and various business documents to see how the tour operator’s practices and procedures comply with the GSTC standard. The documents should be submitted within the deadline stipulated by the Certification Body. The Certification Body will review all documentation submitted and compare to their GSTC Recognized Standard. During this period the Certification Body will consult the tour operator to clarify any questions about its operations. The length of this process can vary depending on the extent of the tour operator’s documented policies.

4. Onsite Audit
The Certification Body will visit the tour operator’s office to see how its policies are put into action. A part of the Certification Body’s process would also evaluate a sample of Tour Operators’ services providers that represents the whole group to ensure that those service providers are in line with its declared business practices. After the Certification Body’s assessment, the tour operator should have a chance to view a draft report and voice any factual objections. This period allows the operator to contest or provide any supporting information to support certification. The Certification Body’s report will then be finalized, shared with the tour operator, concluding whether certification can be awarded.

5. Certification issued
Certification is issued once the Certification Body has confirmed that the tour operator meets the GSTC standard. A formal certificate will be issued by the Certification Body. If the certification application is not approved right away, the assessor would provide the tour operator with recommendations and corrective actions. Tour operators can then work with the Certification Body’s dedicated customer service representative to show the Certification Body that these corrective actions have been followed, so the tour operator can achieve certification. Tour operators should check with the Certification Body to see when the certification renewal process should begin. It generally is between 4-6 weeks prior to the expiration of certification.
