Sustainable Hotel Support Operations?

I’m working on a Management question and need guidance to help me study.

In recent years, most businesses have been striving to minimize their environmental footprint driven by increased cost and environmental concern. In a response to this, consumers and regulatory entities are demanding that hotel operators make an effort to minimize the environmental impact of their lodging operation. Doing so correctly will have a positive ecological, environmental and financial consequence. Hotel managers are looking for ways to reduce the use of water, maximizing the efficiency of electrical equipment, as well as minimizing the waste generated by the operation, all this without negatively affecting guest comfort.
