The study rests on a survey by the Cleantech Group consultancy, researched between February and April of this year. The consultants say they surveyed “over 8,000 … hosts and guests,” and then compared the responses with “research on residential and hotel sustainability levels and practices.” According to the study, North American Airbnb guests are more likely to use public transportation and to recycle than hotel guests are. Airbnb says this saves “the equivalent of 270 Olympic-sized pools of water,” and avoids “the greenhouse gas emissions equivalent to 33,000 cars on North American roads.” Airbnb also says that 95 percent of its North American hosts recycle - far higher than claimed U.S. averages, which vary loosely between 58 percent and 75 percent, depending on where you look.
