How we created the Travelers’ Choice Sustainable Hotels 2024 list

  • We started with diverse, credible and external inputs from our sustainability data partners BeCause. BeCause collated data detailing hotels that have been certified by at least one of a number of Global Sustainable Tourism Council and Travalyst approved organisations (“certifications”).
  • Eligible hotels were those who had valid certifications during the 12-month period of January 1, 2023 to December 31, 2023.
  • In order to help rank the eligible hotels, we underwent an exercise to identify certified hotels on Tripadvisor’s platform. For the identified hotels we then used 70 sustainability terms and phrases used to indicate that Tripadvisor users were talking about “sustainability” in reviews over a 12-month period (January 1, 2023 to December 31, 2023) and thus defined these as ‘reviews discussing sustainability’. Examples of terms and phrases are: “environmentally friendly,” ”refillable,” ”eco-tourism,” “waste reduction,” etc).
  • Then, using the digital listening tool, Brandwatch, we analyzed approximately 23,954 Tripadvisor reviews (in English, which made up 71% of reviews), over the 12-month period for the certified hotels that also mentioned sustainability and had an average Tripadvisor review bubble rating of 4 or above (used as a measure of an overall positive review).
  • Next, for each of these suitable hotels, we calculated reviews discussing sustainability as a percentage (%) of total hotel reviews during the 12 months.
  • This allowed the identification of hotels in order of rank, starting with the hotel with the highest percentage (%) of reviews discussing sustainability (and had a bubble rating of 4 or above) amongst all reviews of that hotel - this hotel ranked (no.1 on the list), through to the hotel ranked no.25, thus creating the Tripadvisor Travelers’ Choice Sustainable Hotels 2024 list.
  • And finally, Tripadvisor is proud to serve a broad and diverse community of travelers and their interests from all over the world. As such, Tripadvisor reserves the right to determine the eligibility of any hotel for an award based on additional factors that reflect Tripadvisor’s brand, corporate policies and values, inclusive of, but not limited to serious safety incidents (e.g. a hotel in an active war-zone, etc).
