Environmental measures for hotels’ environmental management systems

Purpose – Implementation of environmental management systems (EMS) in hotels is gaining popularity world-wide. ISO 14001, which is the only certifying document in the ISO 14000 series, provides guidelines to set up an EMS. However, there is a paucity of information about the actual environmental measures implemented in ISO 14001 certified hotels. Therefore, the purpose of this paper is to identify and generalize the environmental measures undertaken by studied hotels and to evaluate the performance of these environmental measures. Design/methodology/approach – Three case studies were carried out to identify the green measures undertaken in ISO 14001-certified hotels. Both qualitative and quantitative data were collected and analyzed. Then, regression analysis was conducted to examine the relationship between monthly utilities input (electricity, gas, fuel oil and water) and activity parameters. Findings – A total of 113 measures were identified, nearly half of which concern energy conservation. Results of multiple regression showed that R 2 for different utilities varied. The explanatory power of equation was strong for electricity consumption, moderate for fuel gas consumption, and weak for both gas and water consumption. Practical implications – The identified measures provide hoteliers with a thorough picture about the actual environmental works involved in this internationally recognized EMS. Hotel operators and owners can use these measures as a reference either for applying EMS certification or for developing their own EMS. Originality/value – The paper, which was based on operational experiences from existing hotels, was a collaborative work between hospitality industry practitioners and educators. The paper is also the first of its kind to unveil the comprehensive environmental measures undertaken in city hotels with ISO 14001 certification.
