It is an old management adage still true today: “You can’t manage what you don’t measure.” Fortunately, the lodging industry is getting better all of the time at managing its environmental impact. One sure proof of this is the just-released “Hotel Sustainability Benchmarking Index 2016: Energy, Water, and Carbon.” The report was produced by Cornell’s Center for Hospitality Research. Eric Ricaurte, Founder & CEO of Greenview, was the lead researcher and compiled 2014 data from 11 global hotel firms. I spoke with Ricaurte and he told me the data set grew by 40 percent—from 3,250 properties to 4,457 properties since last year’s report. “We are showing more granularity and improvement every year,” Ricaurte said. This is the third year for the study. In the first year the database included utility information from about 2,000 hotels.
