Resumen
Environmental aspects are considered a specific process that requires a multidisciplinary analysis, as the application of indicators in organizations stems from effective performance management; the tourism sector is no exception. In 2015, the United Nations formulated 17 sustainable development goals to contribute to a common vision for people and the planet. The main objective of this study is to propose a framework of science-based environmental sustainability indicators for the hospitality industry, which can be used by hotel managers to improve the efficiency of sustainable management of tourism destinations. This study used a mixed methodology of systematic review and content analysis, which is an innovative methodological approach; an in-depth analysis of various scientific articles, consultancy firms? websites, and technical books was carried out. The results categorized the environmental indicators into four domains: water, energy, waste, and emissions. After a framework was established with 24 environmental indicators, the most relevant were water consumption per guest, water consumption per occupied room, and energy consumption per square meter/foot. However, there were disparities in the use of indicators between the scientific literature, consultancy firms, and the technical books. In this way, there is a need to create stronger relationships between these sources for effective adoption by hoteliers, allowing for adequate environmental indicators with positive impacts on the tourism destination management.
