The fifth annual Cornell Hotel Sustainability Benchmarking study includes data from substantially more hotels than in all previous years. While the bulk of the data come from hotels in the United States, the study also recorded a greater international participation, with fifty-one nations and thirteen international brands represented. More than 10,400 hotels contributed information regarding their energy and water use, as well as greenhouse gas emissions. Complete as of 2016, the data show that the participating hotels generally have continued to reduce their energy and water usage, although the energy intensity recorded by luxury hotels continues to be relatively high. While these data will permit hoteliers and potential guests to see benchmarks for various hotel segments and locations, individual hotel amenities cannot be accounted for in terms of energy or water use. The study was supported by over a dozen international hotel firms, namely, Club Med Resorts, Hilton Worldwide, Host Hotels & Resorts, Hyatt Hotels Corporation, InterContinental Hotels Group, Mandarin Oriental Hotel Group, Marriott International, MGM Resorts International, Park Hotel Group, Saunders Hotel Group, Six Senses Hotels Resorts Spas, The Hongkong and Shanghai Hotels, and Wyndham Worldwide. Data collection is now underway for the 2019 study, and the author encourages additional hotels to participate, especially those in the lower tier segments, which are not as strongly represented in these data.
