Abstract

In recent years, the green hotel market in Belize has experienced notable growth due to the rising adoption of eco-friendly practices and increased environmental consciousness among customers. Despite being an emerging concept in Belize, green hotels play a pivotal role in fostering a green lifestyle and raising environmental awareness among the population. This study focuses on understanding factors influencing customers' intent to choose green hotels in Belize, presenting a consumer-oriented model for assessing hotels' green scores. Through an extensive literature review, 50 critical indicators were identified and grouped into nine key aspects as crucial attributes for selecting green hotels. The proposed model utilizes the fuzzy AHP to determine criteria weights and the fuzzy Technique for Order of Preference by Similarity to the Ideal Solution (TOPSIS) to calculate green scores and rankings. The fuzzy Delphi method is incorporated for survey response analysis, distilling 50 indicators down to the most critical 40 factors grouped into nine key aspects for selecting green hotels. Results highlight "Social Responsibility and Communication" as the most critical dimension. Comparative analyses with fuzzy COPRAS and fuzzy VIKOR validate the findings, contributing significantly to Belize's sustainability, ecotourism, and green hotel selection. The study offers valuable insights for businesses and marketers to formulate effective strategies, providing constructive solutions and directions for future sustainability and green tourism research.
