Sustainability Certifications.

And why they matter!

Why look for certified options?

Certifications can guide both the tourism industry in creating more sustainable businesses and travelers in making more sustainable choices.

Why certifications are important.

We can acknowledge sustainability actions as travelers, but only experts can validate the impact of these actions.

Certifications provide businesses with an important framework to implement and measure their sustainability efforts.

How do I know if a certification is reliable?

Just in tourism alone there are more than 150 certifications, so it can be tricky.

Check if the certifications are validated through third-party accreditation, such as GSTC, ISO, etc.

How do Iย find certified places?

Still less than 1% of tourism industry businesses holds a certification.
On TripDoodler, you can see multiple certifications displayed next to the travelers sustainability ratings.
