HONG KONG—Demonstrating its commitment to protecting the environment and mitigating climate change, Shangri-La Hotels and Resorts, one of Asia Pacific’s leading luxury hotel groups, announced that it will participate for a second consecutive year in Earth Hour, a global Worldwide Wildlife Fund for Nature (WWF) climate change initiative. On March 27, 2010, between 8:30 and 9:30 p.m., more than 60 Shangri-La Hotels and Resorts worldwide will turn off their lights in most back-of-the-house areas and dim the lights in public areas, restaurants and hotel exteriors. Guests will be encouraged to participate by turning off the lights in their guestrooms. Shangri-La estimates that for each hour of shutting off or dimming lights per hotel, it can save up to 60 megawatts of electricity, which is equivalent to providing the lighting energy requirements of a city of 500,000 residents for 24 hours.
