Abstract :

This study aimed to assess the influence of management commitment in the implementation of hotel environmental management practices and its effect on business sustainability among hotels in Tanzania. Studies have shown that management commitment plays a significant role in the implementation of hotel Environmental Management Practices (EMPs). Based on that argument, two hypotheses were formulated as follows; Firstly, Management commitment influences the implementation of environmental management practices. Secondly, Implementation of environment practices have effects on hotel business sustainability. The study was conducted in two cities namely: Arusha and Dar es Salaam whereby a structured questionnaire with Likert scale range from 1 to 5 was used to collect information from the sample of 400 managers and supervisors of hotels.   SPSS software was used for data entry and AMOS software version 23 was used to analyze multivariate analysis and Structural Equation Modeling (SEM) was used to test the hypotheses. The findings indicated that both hypotheses were accepted that is, Management commitment has a positive influence on the implementation of the EMPs with highly significant at p<0.000. Also, the implementation of EMPs has a positive effect on hotel business sustainability strongly significant p<0.000. Therefore, the implications to industry managers and expertise are: first, hotel managers’ commitment plays a pivotal role in the EMPs implementation. Second, the implementation of EMPs in hotels serves as a vehicle in achieving hotel business sustainability. This contributes to a body of knowledge by showing that an environmental factor is a major external component that affects business sustainability in organizations like hotels. Moreover, the study has enlightened that, a hotel manager stands a strategic role in managing the organization based morals and values that address the interest of a bigger segment of its stakeholders. The study recommends future research on further study of water conservation especially on reducing water for showering and bathtubs. It was concluded that commitment of hotel managers in the implementation of EMP plays a pivot role in the sustainability of hotel business in Tanzania.
