This study is important for hotel managers because it shows what practices can be adopted at the environmental level to reduce energy and water consumption as well as to obtain better economic results with their adoption as a set of practices that can be used as benchmarking. Considering all the sustainability practices adopted and described throughout this work, the hotel management estimates that it achieves savings of $40\%$ in the total sum of consumption in relation to the budget forecast for $2019.$ This study also shows managers that the adoption of environmental practices can be considered an investment rather than a one$-$off cost that, thus, might reduce their resistance to adopting them. One of the reasons identified in the literature for not implementing the practices is related to the costs of implementing them $[81].$ This study goes some way in helping managers reconsider this issue. It also contradicts the idea that sustainability practices in luxury hotels dilute the perceived comfort in the eyes of clients $[9,10,11,41],$ and the image and prestige of the hotel $[9,10]$ by showing that, despite the implementation of these practices, the level of client satisfaction remains high, the image of the hotel is good, and the occupancy rate continues to increase. Thus, our study highlights compatibility between luxury and environmental sustainability practices in the hospitality context. This $$positive$$ view is more in line with recent studies that explain the positive reaction of consumers when learning that a luxury hotel is committed to sustainability $[8],$ and studies that show that consumers favor luxury hotels that communicate their focus on environmental sustainability $[8].$ This study also shows that the environmental strategy as referred to in the literature is a key factor for the hotel$$s long$-$term competitiveness.

What are the advantages for hotels and hospitality companies when they implement sustainability practices?
