Tourism usually consumes natural resources. This behavior demands better environmental management that Leads to sustainability. This research aimed to ascertain the operational environmental sustainability practices of Bishoftu resort hotels. Managers attitude and factors affecting performance are also identified. A mixed research design is applied to the study. Quantitative data were gathered from hotel managers through a self-administered questionnaire, and qualitative data were collected through the semi-structured interview from hotel managers and observation on the ground. Quantitative and qualitative data were analyzed through descriptive statistics and thematic analysis, respectively. The environmental practice indicators were examined under the groups of water-saving, energy-saving, green purchase, waste management, and creation of clean air. The results show, that the installation of energy-efficient bulbs and key card/sensor for light, using energy-efficient appliances, the installation of dual toilet and other low-flow water technologies, reuse items like used water for gardening and cloth napkins, and buying of local products were implemented at significant level in sample hotels. But environmental certification program, setting up polices and targets, using alternative fuels and energy sources, and participating in carbon offset projects implementation were insignificant. The results also revealed that more than 99% of hotel managers possess positive attitudes but low level of performance because of owners' less awareness and commitment, low applicability of government rules and regulation on the ground, and the absence of incentives and motivation mechanism for better achievement. The literature to date researched more on corporate level issue, and their targets were external stakeholders and limited departments. But this research examined environmental sustainability practices at the core hotel outlets and property level where policies and programs are into practice. The study's findings provide practical guidance for hotel managers who seek to implement sustainability practices. The information reported in this study would be valuable and useful for the local government and hotel companies in the region as well.
