LightStay, the sustainability measurement system used by Hilton Worldwide and its portfolio of 10 hotel brands, has saved the company more than $74 million since its launch in 2009.
According to 2010 results released this week, the LightStay strategy has so far reduced the hotel chain’s energy use by 6.6 percent and cut its carbon output by 7.8 percent, against a 2008 baseline.
The strategy also cut water use by 3.8 percent and waste output by 19 percent, the hotel chain says.
To date, Hilton Worldwide’s efforts are equivalent to the removal of more than 50,000 cars from the road, water savings that could fill more than 1,000 swimming pools and energy conservation that could provide power to nearly 20,000 homes a year, the company says.
By 2014 Hilton plans to reduce energy consumption, CO2 emissions and waste output by 20 percent and reduce water consumption by 10 percent from direct operations within the company’s properties, against a 2008 baseline.
Earlier this month it emerged that Hilton Worldwide received ISO 9001 and 14001 certifications at 2,750 properties in 85 countries.
The chain is one of 12 international hotel companies including Hyatt, Fairmont and Marriott, that are trying to create a single methodology for calculating carbon footprints and emissions.
