Brebbia and Pineda (2004) claim that financial savings are one of the most significant factors that influence the implementation of environmental initiatives in a hotel. This is especially evident for hotel businesses that operate in a highly competitive market and where the cost of energy, water and waste disposal are high. Hotel operators that can maximize their efficiency and reduce waste will be more cost-effective than their competitors. For example, a hotel can reduce its energy consumption by 20-40% without adversely affecting performance.
