Trend no. 5 : sustainability goes mainstream For those who thought two years ago that sustainability would flame out as a trend (as has occurred in the past), it is now clear that customers’ demand for sustainable hotel operations has taken root and expanded. The hotel industry has taken notice, as demonstrated by a push for consistent reporting standards and industry best practices coming from our industry roundtables in both Asia and North America. In that regard, meeting planners and corporate planners are now requesting that hotels provide sustainability-related information (such as energy use or recycling policies). Third-party certification of green claims has become an important part of sustainability reporting, as demonstrated for instance by Travelocity’s Green Hotel Directory, which does not recognize self-certified hotels.
